This mirrors gtk_css_node_add/remove_class() APIs and allows you to
specify a (set of) state(s) to set or unset.
These functions are purely convenience.
The idea is to wrap size request, size allocation and drawing each into
a function that takes care of the CSS box and then calls a callback to
request/allocate/draw the contents.
The idea is that complex widgets then nest these calls for all the css
nodes they need to handle.
During copy/paste, it may be common that we receive several property changes
around the selection atom, this results in warnings when cancelling the previous
write attempt. We already honor the last request properly, so we should just
cancel silently.
Sometimes path nodes can survive longer than the style context that
created them. Don't crash in those cases.
Fixes startup of mutter.
Testcase included.

This allows monitoring the CSS tree. For now, moving a child to a
different position relative to its siblings while keeping the same
parent will cause a child-added + child-removed emission.
We need to properly track if a node needs to propagate invalidation
state information to its children. We didn't do this properly before and
that could lead to us forgetting to invalidate nodes in corner cases.
Do not propagate the TIMESTAMP change through the node tree, as that
causes lots of uneeded markings of nodes as invalid.
Instead, walk the node tree and find the nodes that have a non-static
style and only invalidate timestamps on those.
Only invalidate timestamps if the node is marked as invalid. We overload
the meaning of "invalid" as "tracks timestamps".
While I don't like the way this is written, it is an important
optimization because 95+% of nodes don't animate so timestamps don't
matter to them. But timestamps are invalidated 60x per second.
We don't return a NULL style to mean "no changes" anymore, instead
we check new_style == old_style to mean that.
Make sure the code reflects this, otherwise we'll send
GTK_CSS_CHANGE_PARENT_STYLE invalidations everywhere and screw up
performance.
Now that the widget node recomputes styles on update_style() we can just
call it during validate(). That way, we don't need the widget node to
manually compute its style.
If CSS values are queried from a widget, recompute them if necessary. Do
not emit style-updated until the validation phase however.
This way, we don't run into performance traps when style-update causes
invalidations that cause new style-updated to be emitted.
... and pass it to the API that computes new styles.
A special timestamp of 0 means "please don't animate" and is used when
no frame clock is available for a node.
This is mainly an attempt to merge the update_style() and validte()
vfuncs. Code is not there yet, but that's the idea.
Also, gtk_css_node_set_style() should not be public. And this gets
closer to that goal, too.
After measuring it, I realized the optimization never triggers for
Adwaita and rarely ever triggers for simple themes. So it is not
useful to keep it around.
This allows adding more API for it.
It also includes code that tracks modifications and invalidates siblings
and their positions whenever nodes get added or removed.
If we know the parent's get_path_for_child() implementation is safe to
be used with GtkCssNode because it doesn't do anything special, we do
that. Unfortunately that requires whitelisting vfuncs because the vfunc
is public API so anyone can override it.
Instead, use gtk_widget_get_path() which makes GtkWidget cache the path.
This is a temporary solution until we can get rid of widget paths.
This increases memory usage quite noticably.
The node declaration has the same functionality as
gtk_css_node_declaration_add_to_widget_path(). So instead of using that
function on a path, you can use the original path and the declaration in
a matcher.
So far the vfunc is kinda quirky (the path argument is an out argument
for something you have to free when you're done with the matcher), but
I'm about to change that.
We don't want to add the current classes to the widget path - which
might potentially be different after a gtk_style_context_save() - but
the root node's ones. So what better thing to do than actually using the
root node?
Instead of directly requesting the layout phase, register a tick
callback. This is what the docs suggest for animations and it's what we
need for the next commit.
... to a bunch of functions.
This requires a tiny change to the heuristics for the style cache - we
now cache styles when they have the same style provider as their parent
instead of when they have the default provider - but that change doesn't
have any effect in practice.
The parent refs the child, so gtk_css_node_set_parent() adds/removes a
reference.
We should probably refactor this so that we name the function
parent.add(node) instead of node.set_parent(parent) - makes the
refcounting more clear.
Instead of passing the style declaration, take the node's style
declaration. Add arguments to allow overriding the state for the one
case where this didn't work.
The code is confusing the stylecontext=>node transition, so I'll remove
it.
WIth the recent introduction of the parent style cachen, I'm not sure
it's worth it at all. Some crude benchmarking suggests a slight speedup
when removing the cache.
So no guarantees about adding it back later.

- GtkCssPathNode

The functionality of it is supposed to grow, so better put it in a
custom file early.
This is just a naive split so far, the next patches will split things
further.
The wl_data_source may be the clipboard's. Looking up the drag context in
order to get the display isn't going to fare well there. So, just use the

This commit adds the GtkTextTag:underline-rgba and :strikethrough-rgba
properties and the necessary plumbing to apply these colors in GtkTextLayout.
With this change, you can alter the color of underlines including those
of type PANGO_UNDERLINE_ERROR.
You might want to alter the underline color to differentiate between
spelling and grammer mistakes. In code editors, it is convenient to
differentiate between errors and warnings.
Note that the GtkTextAppearance struct is public ABI and has no spare
room for new fields, so we are resorting to some tricky packing to store
the colors in the unused pixel field of the fg_color and bg_color structs.
This packing is accomplished by the macros in gtktextattributesprivate.h.

We are testing -gtk-icon-style and assume the theme doesn't touch it.

Support scaling of cursors created from themes. The default scale is

The setting of the the surface scale even when the surface is not

that we get the buffer from a non-existing surface when the wl_cursor

With the 3.0 transition, this code went from just querying the entry's
height request to doing a full size request.
Then it got code to revert the features that a full size request does.
And then it grew code that manually computed the baseline.
Avoid this and just do what happened back in the days: Do a regular
height request.
This changes the semantics of the get_frame_size() vfunc wrt its
behavior towards subclasses overwriting the get_height() vfuncs, but I'm
happy to live with that.

When the scrollbars are overlayed, the size requisition of the

This is somewhat tricky to work out, so put some example

"Install" the .pdb files that were generated along with the build, to make
it easier for people to develop and debug GTK+, especially when used as a
stack, and as the .pdb files are already generated with all builds.
Also make the copy of the .dll, .lib and .exe files more selective so that
we do not accidently copy files that are not meant to be "installed", or
end up making extra copies of plugin DLLs in the wrong places, when the
projects here are included as a part of a grand solution that is used to
build the entire GTK+ stack, for example.
For Visual Studio 2010 and later, the .pdb filename needs to be explicitly
specified so that it will match the filename of the target, if the project
name differs from the filename of the target. Make sure that is the case
for the 3 DLLs that we build for Visual Studio 2010 and later.
Postpone until the last moment whether the target widget still
potentially uses updates from this sequence, or window dragging
actually applies because all gestures on the target went to denied
state.

Use the /MP compiler option, where the build time for release builds can
be cut down by quite a bit. This will however cause a brief warning with
debug builds due to the use of /Gm, but the code will otherwise build
normally. Unlike the Visual Studio 2010+ builds, we can't use /d2Zi+ as
Visual Studio 2008 does not support that, so we can't get a better
debugging experience for release builds here.
Use Multiprocessor compilation which can cut down build times by quite a
bit and use the /d2Zi+ flag to have better debugging info being logged to
the .pdb for release builds.
These are only applicable for Visual Studio 2010/2012 and later.

When a window is hidden, its surface and all its roles are destroyed,
if this happens when we already issued a wl_surface_commit and are
awaiting for a frame callback, the clock will remain frozen for the

and ensure the clock is thawed after hiding. If we happen to receive

The gesture is hooked to the capture phase, so it works for buttons in
header bars and whatnot. In order to be friendly to the widget it is
capturing events from, an ugly hack is in place to avoid capturing
events when the target widget has a gesture that would consume motion
events.
This happens on button release, which is more convenient if the gesture
can be consumed by something else (eg. window dragging), and already behaves
correctly wrt cancelled gestures, broken grabs, etc.
This also allows us to unify pointer and keyboard behavior, popping up the
menu widget in a single place.
There are two scenarios. A widget sub-class owns a GtkEventController
and passes itself to it, or a controller owned by something else is
passed a widget.
In the second case, if the widget is destroyed before the controller,
we will have a crash when destructing the controller because we will
be accessing invalid memory. Adding a weak reference on the widget
addresses that problem.
This leads to a crash in the first case. When the widget is getting
destroyed, it will drop the reference to its own controller. The
controller will skip touching the widget because the weak reference
would have turned it to NULL. However, when the widget sub-class chains
up to GtkWidget it will try to free all the controllers in its list.
Unfortunately, all these controllers have already been destroyed. So
we need to guard against this too.

Add a way to set a delay factor that can be used
to make the long press more or less sensitive.
Making this a factor instead of exposing the delay
itself preserves the value of the setting as an
overall 'slow down long press' setting.
As Sebastian pointed out, just resetting the initial slider
position was an incomplete fix, because it does not cause the
delta to be recomputed, which is important in this scenario,
because you've likely travelled some distance over the slider
before the long press kicks in.
Instead, explicitly record both the slider position and the
delta.
We record the starting position on button press, but only
start the zoom mode when the long press timeout kicks in.
Depending on circumstances, this can cause a noticable jump.
Avoid this by resetting the recorded starting position after
the long press timeout. Suggested by Sebastian Keller.
First, attributes can be NULL (which is always the case when calling
gdk_window_ensure_native) so do not unconditionally dereference it.
Then the window_type should be taken directly from the GdkWindow as

While a popover is hiding, the modal grab is already gone and the toggle
button is clickable again, but clicking again at that time will result in
gtk_widget_show() trying to show an already shown widget (although fading
out and hidden soon) and the toggle button activated.
So let the menubutton set the active status only if the menu/popover
widget wasn't already shown, and ensure this doesn't get triggered by
double/triple button press events.
As an implementation detail, the popover hooks the fade out animation
on ::hide. Destroying the popover right away here is not a problem, but
prevents the animation from actually running. ::unmap will be run after
the animation is finished, so destroy the popover there.
These have the same visual effect and timing than the gnome-shell ones.
During the hide animation, the popover has been made to take focus
elsewhere, and refuse to take any pointer/keyboard input until the popover
is shown again.
This has been based on work from Timm Bäder.

It will be useless to check the source window on the destination side,
it's at the moment always NULL. Fetch the display from the device instead,
which will be set for every GdkDragContext.
At the time of creating the indicator window, the scrollbar allocation is
poked and reused as the initial window dimensions. This usually happens
on two circumstances, either initially (so a ::size-allocate is emitted,
relocating the windows in the right places), or post-initialization when
calling set_overlay_scrolling() (so the scrollbars already have a valid
size allocation)
However, if the scrolledwindow is unrealized, and later re-realized again,
the scrollbars will already have a valid allocation, although 0,0 based
due to being contained in the previous indicator window. This comes out
wrong then, and the indicator window is given 0,0 based coordinates too.
Fix this by refactoring the scrollbar allocation code out of size_allocate,
and also use that given size at the time of creating the indicator windows,
this will provide the right widget-relative allocation anytime.
Currently, GtkGLArea will leak GError instances set during the context
creation, if an error is set.
If any error is set post-context creation, it should be displayed even
in the case a GL context exists; for instance, we can use the error
display facility for shader compilation errors.
Make that variable go from 0.0 to 1.0 where 0.0 means inactive (slider
is on the left) and 1.0 means active (slider is on the right).
The math is simpler that way and most importantly the value is
independent of size.
Add a button to allow restricting search to the current
folder (and subdirectories). This makes the search more
useful, and makes the file chooser more similar to
nautilus.
In search, we show files from differnt locations, and it makes
sense to show where they come from. This makes the file chooser
more similar to nautilus, too.
Folders that show up among search results were unexpectedly
returned even for GTK_FILE_CHOOSER_ACTION_OPEN. Change things
around so that we switch to the folder instead, which is the
behavior we had in GTK+ 2.x.

Some compositors might not offer wl_seat 4 resulting in GTK+ clients not
working on that compositor.
wl_seat 4 introduces keyboard repeat information, but when that information
is missing it is retrieved from settings, hence there's no reason to
require wl_seat 4.

This is necessary to avoid unwanted drag cancel animations,
now that GtkNotebook is careful about cancelling a drag
when the dragged tab disappears unexpectedly.
The existence of OpenGL implementations that do not provide the full
core profile compatibility because of reasons beyond the technical, like
llvmpipe not implementing floating point buffers, makes the existence of
GdkGLProfile and documenting the fact that we use core profiles a bit
harder.
Since we do not have any existing profile except the default, we can
remove the GdkGLProfile and its related API from GDK and GTK+, and sweep
the whole thing under the carpet, while we wait for an extension that
lets us ask for the most compatible profile possible.
https://bugzilla.gnome.org/show_bug.cgi?id=744407
Store the OpenGL version when we first do the extensions check; this
allows client code to check the available GL version without requiring a
call to gdk_gl_context_make_current() and epoxy_gl_version().
When using GDK_GL_PROFILE_3_2_CORE, we are not only specifying that the
GDK should create a core profile; we are also specifying that the
minimum required version of OpenGL is set to 3.2.
We should also specify that the GDK_GL_PROFILE_DEFAULT profile is an
alias for GDK_GL_PROFILE_3_2_CORE.
Now that we have a two-stages GL context creation sequence, we can move
the profile to a pre-realize option, like the debug and forward
compatibility bits, or the GL version to use.
gtk_list_box_bind_model() binds a GListModel to a GtkListBox.
This is a first step towards having GListModel support in Gtk. It's not
useful for large models, because GtkListBox always creates all widgets
for all rows.
Emit an error if the profile is different.
This is a follow-up commit to commits cc45e82 (x11/gl: Ensure we use the
3.2 core profile) and 2d9081d (wayland/gl: Ensure we use the 3.2 core
profile), so that we do the same on GDK-Win32. Update variable names and
comments so that the code is clearer to people, as we still need a
temporary legacy WGL context first before we can use
wglCreateContextAttribsARB() to create a WGL core (3.2+) context.
https://bugzilla.gnome.org/show_bug.cgi?id=741946
Using version 1.20 with a forward compatible 3.2 core context is incorrect
since OpenGL 3.2 deprecates shader version 1.20 (See section E.2). The latest
fglrx drivers will not compile these shaders.
https://bugzilla.gnome.org/show_bug.cgi?id=744203
Since we dropped the legacy OpenGL compatibility profile, we need to use
recent OpenGL APi and concepts. This also means that the example code
gets a tad more complicated.
https://bugzilla.gnome.org/show_bug.cgi?id=741946
We simply don't want to care about legacy OpenGL.
All supported platforms also have support for OpenGL ≥ 3.2; it would
complicate the internal code; and would force us to use legacy GL
contexts internally if the first context created by the user is a legacy
GL context, and disable creation of core-3.2 contexts after that.
We will need to fix all our code examples to use the Core 3.2 profile.
https://bugzilla.gnome.org/show_bug.cgi?id=741946
Like what is being done in the X11 and Wayland backends, create the
GdkWin32GLContext in 2 steps, where we only create the actual WGL context
in _gdk_win32_gl_context_realize().
https://bugzilla.gnome.org/show_bug.cgi?id=741946
Users of the GdkGLContext API should be allowed to set properties on the
shim GdkGLContext instance prior to realization, so that the
backend-specific implementation can use the value of those properties
when creating the windowing system specific resources.
The main three options are:
• a major/minor version tuple, to request a specific GL version
• a debug bit, to request a "debug context", which provides additional
validation and run time checking
• a forward compatibility bit, to request a context that does not
have deprecated functionality
See also:
- https://www.opengl.org/registry/specs/ARB/glx_create_context.txthttps://bugzilla.gnome.org/show_bug.cgi?id=741946
One of the major requests by OpenGL users has been the ability to
specify settings when creating a GL context, like the version to use
or whether the debug support should be enabled.
We have a couple of requirements in terms of API:
• avoid, if at all possible, the "C arrays of integers with
attribute, value pairs", which are hard to write and hard
to bind in non-C languages.
• allow failing in a recoverable way.
• do not make the GL context creation API a mess of arguments.
Looking at prior art, it seems that a common pattern is to split the
construction phase in two:
• a first phase that creates a GL context wrapper object and
does preliminary checks on the environment.
• a second phase that creates the backend-specific GL object.
We adopted a similar pattern:
• gdk_window_create_gl_context() creates a GdkGLContext
• gdk_gl_context_realize() creates the underlying resources
Calling gdk_gl_context_make_current() also realizes the context, so
simple GL users do not need to care. Advanced users will want to
call gdk_window_create_gl_context(), set up the optional requirements,
and then call gdk_gl_context_realize(). If either of these two steps
fails, it's possible to recover by changing the requirements, or simply
creating a new GdkGLContext instance.
https://bugzilla.gnome.org/show_bug.cgi?id=741946
This guarantees we only create 1 extra style cascade in total for hidpi
and not one per style context.
Style cascades are now nested like this:
GtkSettings root cascade (scale == 1)
|
+-- GtkSettings per scale cascade (for any scale, no custom providers)
|
+-- GtkStyleContext custom cascade (for any scale, custom providers)
This requires a bunch of care when changing cascade-related properties
inside GtkStyleContext, so that it ends up with a properly setup
cascade, but I think I got those cases right.
The only thing we don't do yet is reverting to a GtkSettings cascade
when the last custom provider is removed from a custom cascade.
The default ->upload_texture() works also for Windows since commit 27cf0fa,
as some of the problems described in 742953 also applied for GL core
contexts on Windows as well before 27cf0fa. Clean up the GDK-Win32 code a
little bit as a result.
This property is necessary to ensure widgets automatically update after
the text scale factor is changed desktop-wide.
And if I'm already doing a property like this, I can make it
overridable. So now you can override the dpi per-widget with CSS like
GtkSwitch {
-gtk-dpi: 48;
}
if you want to debug things.
Long-term, we want to get rid of this property and insist on dpi being
96 everywhere and people can change the font size to get larger fonts.

Mouse over a parent menu[bar] didn't work while the menu was open.
The fix was to correct the behaviour of pointer crossing events so that
the pointer appears to be only inside one window at a time.
See: http://tronche.com/gui/x/xlib/events/window-entry-exit/normal.html
We need this because it fixes menu activation. The menu activation code
looks at the time between events to determine if mouse clicks happen too
quickly.
This avoids showing the scrollbars if we are positive the child widget
is being manipulated, regardless of the pointer being close to any of these.
On the next motion event after finishing the operation, the scrollbar will
be shown if necessary.
https://bugzilla.gnome.org/show_bug.cgi?id=743894
is_visible() wasn't the right check to perform here before unmapping,
and gtk_widget_unmap() already avoids being doubly called by checking
gtk_widget_get_mapped() anyway.
Rename the "install" projects as "gtk-install" as we are planning to have a
grand solution file that incorporates all project files of the GTK+ stack
with their dependencies, to make it easier for people to build GTK+ from
scratch from a stock installation of Visual Studio 2008 and later.
In that case the scrolledwindow still gets events through the captured
handler, and can thus still control visibility, so hiding the indicators
in this case can only lead to flashing.
This will be used to just detect when an edge of the scrollable area is
reached - as opposed to the edge-overshot signal that is emitted when
the user scrolls past the edge.

If a side of the box is 0px wide, make the corners owned by the adjacent

got rid of it when amending the test.
Commit ff256956b2 introduced a frame_clock_events_paused

The code here was always a bit buggy: We removed the tab from
the notebook in a ::drag-data-received handler. But with
GTK_DEST_DEFAULT_DROP, that signal is emitted before we inform
the source side that the drag is finished. With its improved drag
handling, GtkNotebook now interprets this as a 'spontaneous'
removal of the tab being dragged, and cancels the drag, leading
to an unwanted cancel animation.
The easiest fix is to just defer the tab removal to an idle.
When a tab is dropped, we have to remove it from the notebook to
insert it elsewhere. This is expected part of the tab dnd operation,
and we need to differentiate it from 'spontaneous' removals which
cause us to cancel the drag operation.
when the dragged tab is being removed during the drag operation,
we need to cancel the drag. To do so, we have to keep around
a reference to the drag context.
This should fix
https://bugzilla.gnome.org/show_bug.cgi?id=732051
Add a gtk_drag_cancel() function that can be used on the
source side to cancel an ongoing drag operation. This can
be useful, e.g. if the data that is being dragged becomes
unavailable.
It is a bit misleading to have one of the places in the sidebar
selected while in search mode, since the search is not relative
to any location. So, unset the sidebar selection when we enter
search mode.
If the search entry doesn't consume the key event, don't
change to search mode. Otherwise, we interfere e.g. with
Ctrl and Shift keys for selection.

If the grab belongs elsewhere, the window won't claim the sequence right

Previously, we would not include any child widget on the first
allocation, which happens right after realize(), but before map(). No
widget is drawable at that point.
The rotation code in the draw_arrow function was assuming that the arrow
would be drawn pointing upwards but it was pointing to the right
resulting in the rotated arrows pointing in the wrong direction.
The recent refactoring caused a pi/2 rotation to be lost. Rather than
adding that back somehwere (to lose it again in the future), we just
draw the arrow pointing upwards as it is expected to do with a 0 angle.
Yes, I like playing around. To enjoy, add this CSS to your application
of choice (preferrably glade or something with lots of images):
GtkImage { animation: spin 2s linear infinite; }
You can thank me later.
The spinner is a regular builtin image now. There is no need to go
through the shadows code manually anymore as regular items do get
shadows automatically.
This also allows simplifying the actual spinner drawing code so that it
actually works.
The order in which properties are defined depends on the order in which
they are computed. And that means that properties can only depend on
other properties that are defined before them.
The next patches will need this reordering.
Instead of supporting every angle, just support top, right, bottom and
left and round the angle to one of those directions.
Adwaita overrides arrows anyway and doesn't even look at the angle, so
this should not be a problem.
Also, make it have a generic entry point with
gtk_css_image_builtin_draw().
The only feature lost so is the drawing of shadows for spinners, but
that will come back later.
The file chooser code now calls into the path bar in init,

GtkImageMenuItem always packs a GtkImage when it is synced with a

The last round of filechooser redesign work had left
search somewhat dysfunctional. This commit fixes things
up enough that search is once again a working feature

There are some cases where we can end up showing the path

1) Open file chooser
2) Hit ~
3) Hit Ctrl-L
While this is a bit of a workaround, at least it makes sure
that we never end up with an empty space where the path bar

This gets rid of a bunch of awkward transitions. It's not a perfect

If this is done on dispose(), the widget may be destroyed (and its
controllers list NULLified) within _gtk_widget_run_controllers(),
causing warnings/crashes when it just tried to hop on the next
controllers.
Freeing the controllers here should be a safety net for implementations,
so it also makes sense to do this late. The widgets that choose to
free their controllers on dispose can still do so, and get
_gtk_widget_remove_controller() called for these as an indirect result.

If a gtk_style_context_invalidate() is called on a widget's style

the animations.
Fixes crashers in Nautilus.
When we get a leave event, we need to remove the over bit,
since we may not get motion events that tell us when we lose
proximity, but we don't have to fade out right away - that
will happen on its on due to inactivity a bit later. Having
the indicator stay visible for a bit feels more relaxed.
If we use GDK_GL_PROFILE_3_2_CORE we are asking for a core profile
according to the GLX_ARB_create_context_profile extension. For that,
we pass the GLX_CONTEXT_CORE_PROFILE_BIT_ARB value for the
GLX_CONTEXT_PROFILE_MASK_ARB attribute.
The specification for the extension says that:
If the requested OpenGL version is less than 3.2,
GLX_CONTEXT_PROFILE_MASK_ARB is ignored and the functionality
of the context is determined solely by the requested version.
Since we're asking for a core profile, we assume a GL version greater
than or equal to 3.2; thus, we don't need to specify the
GLX_CONTEXT_MAJOR_VERSION_ARB or the GLX_CONTEXT_MINOR_VERSION_ARB
attributes, and instead just rely on whatever version GLX gives us.
This seems to work around a strange issue in Mesa; if we ask for a core
profile and any version > 3.0, we get broken rendering on any shared
context we create.
Since gsize doesn't work as a typename in a ui file,

We need to clear the cache manually on full revalidates because
_gtk_css_change_for_child() will clear the full revalidation flags.
And then gtk_style_context_update_cache() will not do the right thing
(which is to clear itself).
Because we can switch from animating to non-animating pretty much
anywhere, do the check for animations unconditionally instead of trying
to cram it into the correct if path (and failing).
We now cache the results of lookups on the parent GtkCssStyle. This
allows sharing styles between widgets (recursively). However, this
only works if the styles can't potentially depend on siblings -
neither directly via sibling selectors or via position pseudo-classes
like :first-child.
Unfortunately, Adwaita currently uses first-child a lot, and in
particular for labels, which are the most common widgets.
The big benefits of this change are both less CPU - due to not needing
to compute styles again - and less memory usage - due to sharing of
the styles between widgets. Here's some nonscientific numbers I
collected while pondering the usefulness of this patch:

Previously we looked at the save/restore state when determining the
parent. This is wrong in the case where we're updating the cache though.
So we now save the parent in the style info.
After the parent changes in commit
3a337156d1 we need to refresh the cached
styles after the current style. After all, they now depend on the base
style.
After 3a337156d1 style lookups still used
the parent context's style as the parent style, even though after a
gtk_style_context_save() the root style of the style context is the
proper parent.
Testcase attached.
Instead of keeping an animated style everywhere, we replace it with the
static style when nothing gets animated.
Apart from making the code cleaner, this gets rid of a bunch of animated
style values that do nothing but wrap a static style.
The only style that is animated is the style of the unsaved primary
node. So there's no need to create animated style objects for the other
ones.
There is a bunch of ugliness in the code currently. Further commits are
expected to fix them.
For now, this is only an implementation detail of the animated style.
The idea is to use GtkCssStaticStyle as the result of CSS queries and
then put a GtkCssAnimatedStyle on top that manages the animations. The
neat thing about this is that you can cache the static values.
GtkCssStyle is the base class to be used for all types of styles that do
exist.
GtkCssAnimatedStyle is the only implementation so far, that is exactly a
copy/paste of the old GtkCssStyle code.
I removed it in 14f5ce7108 because I
thought it was unnecessary, but it wasn't. When we build a tree like
this:
.matches ─┬─ .doesntmatch
└─ .alsodoesntmatch
We would get the changes for the .matches part returned. This is however
only right if that node of the tree contains results. If results only
exist with the child nodes (all of which don't match), then this part
should not match either.
GtkCalendar can have an invalid date — mostly at initialization. This
means that GDateTime construction may fail. We need to handle that case
gracefully, like the old code did.
This fixes the `notify` test suite, which started failing with:
/Notification/GtkCalendar:

Sending backingScaleFactor to a NULL NSWindow will silently give the

properly anymore, since we forgot an invalidation flag. The
problem can be observed e.g. by running gtk3-demo and calling
gsettings set org.gnome.desktop.interface font-name "Cantarell 22"
On the wayland backend, set up GDK_WINDOW_SUBSURFACE windows
for popovers. In the popover code, the popover-relative-to-parent
calculation had to be tweaked, and it's been made to always prefer
the given popover position, since there's no sizing limitations.

We were asserting priv->filename != NULL in various places,
which leads to apps refusing to work when HOME is set to a
nonexisting or nonwritable value. Since it isn't hard, just
make GtkRecentManager survive without a filename. We won't
save or read any recently used files in this state, but
thats ok.

Provide a mechanism for hiding the "Quit", "About" and "Preferences"
menu items from the normal places in a traditional menubar layout (in
the File and Edit menus) when the menu is being rendered in the Mac OS
menubar.
These items can already be found in the application menu.
With this feature, applications can now define a single menu to use in
all 'traditional' scenarios.
Use this new attribute in Bloatpad.
https://bugzilla.gnome.org/show_bug.cgi?id=741610
In addition to the fixed-size mode that is used by the text view,
add a mode in which the magnifier requests enough size to render
the entire inspected widget at the current magnification. In this
mode, the magnifier will update its size when the size of the
inspected widget changes. Also, make the magnifier redraw on its
own whenever the inspected widget draws.
There is no good reason to assign the value directly.
Also, this fixes d23f3254b7
where widgets that chained up instead of calling
gtk_widget_set_allocation() would not draw becaues of empty clip.
(1) Get rid of supports_clip flag. All widgets (implicitly) support
clip.
(2) Don't reset the clip to { 0, 0, 0, 0 } before the "size-allocate"
signal.
(3) Make gtk_widget_set_allocation() set the clip (to the allocation).
This ensures that eveyr widget has a clip set.
Note: It overrides previous calls to gtk_widget_set_clip(), while in
3.14 this didn't happen.
(4) As the clip is set by gtk_widget_set_allocation() now, don't set
it after the "size-allocate" signal anymore.
This fixes calls to gtk_widget_queue_draw() from inside the
size_allocate vfunc.
We've observed hangs of mutter when it initializes GTK+, which
are caused by initializing GL, which in turn makes xwayland
call back into mutter. With this change, mutter should just
disable GL support in GDK, and things will work.
Override the gtk-shell-shows-app-menu and gtk-shell-shows-menubar
settings to FALSE, if we can detect that we are not on the same
session bus as the xsettings provider that we got these settings
from.
We determine this by comparing the bus ID of 'our' session
bus with the one reported in the Gtk/SessionBusId xsetting.
If they are different, then it very likely that we are in an ssh
situation where we see the forwarded X display, but not the
session bus. The D-Bus based menu exporting will not work
in this situation.
https://bugzilla.gnome.org/show_bug.cgi?id=671802
The magnifier is now set enough height to show the line being currently
manipulated, which makes it just big enough to show the layout height at
that size and magnification.
- It is not possible anymore to trigger text DnD through touch, pressing
and dragging from within the selection will instead extend it. Text
shrinking is still available through the handles
- The selection mode for touch is per-word, char-level manipulation is
still available through the handles.
- Tapping within the selection will bring in text handles, and toggle
text selection popover.
This mode could also shrink the selection, plus the starting point would
seem somewhat arbitrary (actually dependent on the dragging direction of
the last selection).
Made this mode more consistent by only allowing it to extend the selection,
only in one direction for each operation, and so it keeps the current
selection as a minimum.
Instead of passing a GdkEvent and let the function figure out whether the
selection should be extended, let that to the caller and just pass a
boolean here.
Using the parent widget context is a leftover of the pre-popover
implementation, which used GdkWindows directly. This will make the context
reflect widget state, at the expense of changing the selector paths
that used to match the handles.
Checking the return value was valid for most gestures, but
GtkGestureLongPress, where the first press triggers internally an action,
but does nothing for the sequence to be claimed/denied, FALSE was eventually
returned, and the button/sequence functions would be incorrect when
::pressed is emitted.
So check that the sequence is being handled by the gesture, this is more
desirable than the return value as it's independent of sequence state,
and still will be FALSE for the cases we want to catch here.
When a RTL paragraph is not set to wrap, the right margin is not respected
because of the margins counted twice so we replace
display->width by PIXEL_BOUND (extents.width), the same quantity
without the margins.

GtkIconTheme doesn't scale icons beyond the size specified in the theme
anymore. This can result in arbitrarily large menu items when a theme
only provides large icons.
Force icons to always be 16x16 to ensure that menu items always have the
same height.

Since the support for GL support in the GDK Windows backend has landed in
master, we need to build it in the Visual Studio builds. Update the
projects for that and "install" the public header that was added.
This adds support for OpenGL to the GDK Windows backend using the WGL API
calls, which enables programs that uses the GTK+ GLArea widgets to work on
Windows as well.
This also adds a simple utility function to query for the version of OpenGL
that is supported by the Windows system, like the one provided by the X11
backend.
Many thanks to Alex (and Emmanuele, who started the OpenGL integration in
GTK+) who offered advice and help along the way, as well as the X11 and
Wayland backend for this work to refer to and to model upon.
https://bugzilla.gnome.org/show_bug.cgi?id=740795
As the alignments, strides and image formats may be different across
platforms, make the texture upload a vfunc to allow backends to override
the GL commands for uploading textures for the software implementation for
gdk_gl_texture_from_surface(), if necessary.
Suggested by Alex to avoid copying non-trivial portions of code which would
then add maintainenace burden.
https://bugzilla.gnome.org/show_bug.cgi?id=740795
This drops the maybe_allocate_buffers that re-allocates buffers
at any point. Instead we just set have_buffers to FALSE and have
the buffers re-created when needed.
This also makes the buffer creation code imdeponent and makes it
clean up no longer needed buffers in order to handle being called
multiple times due to the above.
We also ensure we re-allocate the buffers when we're resizing
and the buffers are already created.
We can't combine multiple draws into one for the software fallback,
because each quad has a different texture. And we generally don't
want to make a larger single texture because then we would have
to upload more data.
On creation, we call action_removed() in case the action was missing
from the start. Because we just created the action, 'can_activate' will
always be FALSE here and this function will therefore always do nothing.
We do want the visibility state to be updated though, for the case where
the action is missing but the item should still be visible from the
start.
Update the visibility directly instead of trying to call
action_removed().
https://bugzilla.gnome.org/show_bug.cgi?id=735122
We were only properly setting the "is-visible" flag to TRUE for menu
items with associated actions and not (for example) on submenus.
This was fine because the code for building GtkMenus from models
(correctly) assumed that submenus should always be visible and never
checked the property.
This is not true for the Mac OS code, which actually checked the
property and found it to be false for submenus.
Initialise the property to TRUE so that we get the correct value
reported for items that don't have actions.
https://bugzilla.gnome.org/show_bug.cgi?id=735122
All popover sides have extra margins to possibly hold the tail, this is
accounted for in gtk_popover_get_rect_coords(), and should be accounted
for too in the tail position calculation.
This fixes the gtk_render_frame_gap() warnings seen when a popover is
pushed far too close to window sides.
After b49c7c3421 we were no longer doing a
full revalidate after GTK_CSS_CHANGE_SOURCE changes.
This fixes spurious failures of widgets not properly updating when
changing the theme.
These functions, while added for use by the GTK inspector, are generally
useful to applications that need to resolve what action groups are
available to a particular GtkWidget.
https://bugzilla.gnome.org/show_bug.cgi?id=741386
Without this, the focus will not be inside the top_stack when
we switch to the statistics page and it shows the excuse. This
in turn will make the next page not take focus as expected when
switching away from the statistics page again.
Add notebook-like focus handling: Keep track of the last focused
descendent of each page, and focus it again when switching back
to the page. If there is no last focused child, we move the focus
into the page as if the user had hit Tab.
When using a completion with some custom cells in the cell layout,
if would often size wrong when first presented on screen.
The entry completion is the only place in the entire gtk code base
that calls gtk_tree_view_column_cell_get_size outside of gtktreeview
itself. It calls into the function before the tree view has done some
important validation on its cell state, the net result of which is
only the first element in the gtkcellareabox the entry completion uses
well actually have its size respected.
We now call gtk_widget_get_preferred_size on the tree view before
calling into the individual cell size routines, to guarantee that the
tree view has run its validate_rows routine and cell state is valid.
https://bugzilla.gnome.org/show_bug.cgi?id=741130
Use the new scrollable API for getting non-scrollable borders
and draw over/undershoot at the right place. In practice, this
means that they now appear below treeview headers.
Add a vfunc to return a non-scrollable border around scrollables.
This would be nicer as a property, but we can't add properties
to an interface without breaking 3rd party implementations, so
make this an optional vfunc, and handle it not being set.
The new region selector tracks more than just one soimple selector, so
it requires some more advanced specificity tracking.
Technically, this is still not correct, because it will report the same
specificity for
tab:sorted
and
tab:sorted:sorted
(and the second selector will be printed as the first) but this is
regions, so meh.
This is just a way to handle regions more conveniently. What this does
is to change the descendant matcher into a maybe-descendant matcher
whenever the current object we're parsing might be a region. Because "*"
might also refer to a region and not just a new element.
See testsuite/reftests/css-match-region-matches-star.ui for a testcase.
When parsing a selector like
tab:active
We used to create 2 selector objects, one for the region, and one for
the pseudoclass. Now, for convenience, we special-case region
pseudoclass parsing so that the active flag is added to the region
selector.
A side effect is that ":nth-child(1)" no longer works for regions.
Hopefully people didn't use this but used the saner ":first-child"
instead.
We used to switch to the objects tab when an object is
picked, but now may have two places with picker buttons:
the objects tab and the interactive tab.
So, just don't do that anymore.
Currently we only take into account the window GActionGroup for
activating the accels.
However, the application could have some custom GActionGroup in the
chain of focused widgets that could want to activate some action if
some accel is activated while that widget is focused.
To allow applications to set accels on widgets that use custom
GActionGroups, simply use the muxer of the focused widget, which
already contains the actions of the parents.

Adding rows to the bottom of the list is confusing as you cannot see

Most of the core GNOME applications (eg., gnome-control-center,

Since widgets subelements are now both widget childs and widget
classes, say .spinbutton.button and .spinbutton .button,
the linking logic needs to be adapted to be stricter with
child selectors. This fixes vertically linked spinbuttons.
Since widgets subelements are now both widget childs and widget

This fixes vertically linked spinbuttons.
If the previous focus widget is unmapped (eg. hidden, scheduled for
destruction, etc), make the popover forget about it and grant focus
back to the window itself.
The shadow rendering code had code to exit early if we determine
that the shadow is entirely clipped away. Unfortunately, the check
based on cairo clip extents fails for any clip regions that are
more complicated than axis-aligned rectangles, and we are using
a hollow rounded rectangle here. So, instead, do the check manually,
using the just-introduced API in GtkRoundedBox.
This adds two functions for checking whether an axis-aligned
rectangle is completely outside or inside of a rounded box.
These are not trying to be exact, but fast.
As the print preview command is moved into the sources, don't define it in
the preprocessor definitions. However, define the
GTK_PRINT_BACKEND_ENABLE_UNSUPPORTED in the preprocessor definitions, to
make the build in-line with the autotools builds.
We were concatenating "file://" to the result of g_get_user_special_dir() to build
a URI, but this is not enough on Windows. Use g_filename_to_uri() instead.

Previously, the inspector would not change the hilight while the
previous hilight was still flashing.
This is inconvenient while arrowing through the object selection
treeview though where you want the currently selected row to hilight
when arrowing quickly.
The GTK_FILE_SYSTEM_ENABLE_UNSUPPORTED define is not used anymore,
and we don't install a gtk.css file for Raleigh, so no need to
uninstall one either.
gtk-update-icon-cache is no longer used at build time, so a lot
of the complicated machinery we have around that (conditional
build, cross build, etc) are no longer required.
The files for build of GtkInspector have been intergrated into the build of
the main GTK+ DLL, and the Visual Studio project templates for those have
been removed as well. Make that removal complete by removing from the
solution files references to it and make the 'gtk' project not to depend on
the gtk-inspector project.
1) Use font-size instead of color
This makes it easier to compare reference and test because the values
don't change.
2) Actually sort the reference properly
This unbreaks the test.
This subdirectory gets in the way when integrating the inspector
build more fully with GTK+, and does not really add anything.
Just move everything one level up.
I checked Cairo source code (actually pixman, as Cairo just passes
through) to make sure that the behavior stays identical: negative values
cause an error message from pixman, zero is allowed. Both return an
empty region which gtk_widget_queue_draw_region() would then proceed to
ignore.
The calls to cairo_translate in
_gtk_print_context_rotate_according_to_orientation,
_gtk_print_context_reverse_according_to_orientation and
_gtk_print_context_translate_into_margin assume an unscaled context.
These functions should therefore be called before scaling the context,
otherwise the origin does not always end up in the top left corner.

gtk_window_propagate_key_event() will run unstopped from the focus widget up to the
popover if GDK_EVENT_PROPAGATE was returned along the chain, resulting in infinite
recursion. This could be just triggered by pressing some modifier key on an entry...
If a file system event arrives while GtkFileChooserWidget is asking the
user to edit the name of a newly created folder, the file system model
will drop the row with the editable cell, and the user will have to
start from scratch.
This makes creating new directories impossible inside a directory with a
file currently being downloaded, for instance, and it's really unhelpful
to the user because the editable row simply disappears.
We already have a mechanism in place to freeze the file system model, so
we can reuse it between the add_editable() and the remove_editable()
calls.

We directly get the length of the secret from the g_variant

This is a bit bizarre, but the cell renderer can apply different
flags from the actual style context, and we should use those instead
of the widget flags.
:not() works for names, ids, classes and pseudoclasses based on states.
It does not yet work for positional pseudoclasses (like :last-child or
:even) as there is region madness going on with those.
The adjustment value being equal is checked by
gtk_adjustment_set_value() and the necessity of calc_layout() is handled
by the value_changed signal handler.
This is the expected behavior while the popover keeps the grab, leaving
this up to the toplevel implementation gives place to key handlers
connected there to handle the event otherwise, and maybe redirect key
events somewhere else.
NULL-plus-something could be seen by the compiler to attempt to do
arithmetic with void *, which is a GCCism. Instead, do the math normally

Use xdg_surface_set_window_geometry() to tell the compositor about the
shadow widths, this makes some gnome-shell/mutter features (edge resistance,
frames around windows in the overview, side maximization, ...) work alright
with GTK+.
In order to add this, some other places in gdkwindow-wayland had to gain
some knowledge about margins:
- xdg_surface_configure() now syncs the shadow after applying the state,
and gdk_wayland_window_set_shadow_width() possibly reconfigures the
window in order to preserve window geometry. This is necessary to keep
shadows in sync with state/geometry changes, as this does not happen
all at once.
- xdg_popups relative to an xdg_surface are shown relative to buffer
coordinates, so the left/top margins must be added there.

This requires us to use GL_TRIANGLES and six verts per quad instead
of four, which makes me think it might not be worth it on
well-optimized GL drivers. However, from talking to some driver
developers about it, the GL_TRIANGLES should be faster, since this
means that there's one giant contiguous buffer instead of many small
buffers.
If we were really rendering a lot of quads, I'd use an element buffer
and GL_PRIMITIVE_RESTART, but we're really not ever rendering that
many quads, and the setup cost for that would just be too annoying.
It's unused. At the same time, rename "begin_paint_region" to
"begin_paint". This will help us clean up how GDK painting works
in the future to allow more creative use of double-buffering.
...for Broadway builds, as it was producing a wrongly-named check file for
that configuration, so that a clean would not be correctly performed and
subsequently affected rebuilds.
This is needed in the edge case where the X11 backend rounded the actual
size, and the GL flipping really needs the correct window height to
do proper Y coordinate flipping.
https://bugzilla.gnome.org/show_bug.cgi?id=739750
This is required for the X backend GL integration. If the
window has a height that is not a multiple of the window scale
we can't properly do the y coordinate flipping that GL needs.
Other backends can ignore this and use the default implementation.
https://bugzilla.gnome.org/show_bug.cgi?id=739750
Rather than just rounding down the position *and* the size separately
we correctly calculate a rectangle in scaled window coords that fully
covers the real window size. This really only makes a difference
when the window size/position isn't a multiple of the window scale.
https://bugzilla.gnome.org/show_bug.cgi?id=739750
Keep track of the exact size of X windows in underlying pixels; we
generally use the scaled size instead, but to properly handle the GL
viewport for windows that aren't a multiple of window_scale,
we need to know the real size.
https://bugzilla.gnome.org/show_bug.cgi?id=739750
Although we specify a resize increment to try and get a size that is
a multiple of the window scale, maximization typically wins
over the resize increment, so the window might be odd sized.
Round *up* in this case, rather than down, since it's better to
truncate a line or two at the bottom and right of the window rather
than have a line or two that we don't know what to do with.
https://bugzilla.gnome.org/show_bug.cgi?id=739750
The intention was that ::iconic indicates which representation is
preferred (text or icon). We fall back to the other representation
if one is missing.
If the widget is an action widget, it's been previously added with
gtk_dialog_add_action_widget, which calls add_response_data on it, which
in turn connects to the clicked/activate signal of that widget, so we
don't need to connect to that signal a second time in
gtk_buildable_custom_finished.
When overshooting through touchpad kinetic scrolling, the scrollbar remains
mostly static as it already hit a boundary. However, the fade in/out checks
are constantly run during scroll events, causing needless redraws in this
specific case.
The scrollbars are still internal children of the GtkScrolledWindow
and handled in ::forall(), no need to propagate draw here again
after chaining up in ::draw().
During size request, all sides' margins are ensured to be as big
as TAIL_HEIGHT, just to avoid possible relocation loops if the
popover doesn't fit in its original position. This must be
accounted for in size_allocate() as well.
Look for themes in $prefix/themes/$name/gtk-$version/ (for
version = 3.16, 3.14, ...), before using the old location
$prefix/themes/$name/gtk-3.0/. This gives theme authors a
way to support multiple versions of GTK+ 3 with separate
css files.
We really want margins around the scrollable content, not around
the viewport. Make it so by using textview-specific properties.
This is unfortunately a little complicated for top/bottom.
Css margin now works on the slider as they do on the trough.
The margin is not considered in the space allocation as it is for
the trough, so the slider width will be the set slider-width -
margins. Spefifying margins on the main widget in the css will
clearly affect both the trough and the slider, so theme changes are
needed.
The current way of exposing GDK API that should be considered internal
to GTK+ is to append a 'libgtk_only' suffix to the function name; this
is not really safe.
GLib has been using a slightly different approach: a private table of
function pointers, and a macro that allows accessing the desired symbol
inside that vtable.
We can copy the approach, and deprecate the 'libgtk_only' symbols in
lieu of outright removal.

Instead of possibly calling wl_surface_commit() out of
GdkFrameClock::after-paint, tick the transient parent clock so ::after-paint
can be eventually run.
This ensures that the subsurface coordinates (considered part of the state
of the parent) aren't committed untimely, and guaranteed to be orderly with
the wl_subsurface-relative state.
This is a gtk-side fix for https://bugzilla.gnome.org/show_bug.cgi?id=738887
cairo_region_copy(NULL) will effectively return an empty region, as this
function is always meant to return valid memory. This however inverts the
meaning of the NULL region and results in entirely non-clickable windows.
This event might not have an action yet, but certainly accounts, and
should be triggering recognition.
This fixes a crash when attempting to drag CSD windows through touch. As
since cfaec2d2f5, gtk_gesture_single_get_current_sequence() would
rightfully return NULL if the gesture didn't enter recognition, making
event lookup fail.
We need to export the symbols so they can be used in the
inspector, but we don't really want to make this supported
public API, so keep them out of installed headers.
Store the cursor name on the cursor (rather than always using its type).
Use this when setting a cursor on a surface.
The mir server will fallback to using standard cursors from the cursor
theme if the name used is not one of those defined by mir, which is more
or less what we want to happen here in case of creating a cursor by
name.
If buffer age is undefined and the updated area is not the whole
window then we use bit-blits instead of swap-buffers to end the
frame.
This allows us to not repaint the entire window unnecessarily if
buffer_age is not supported, like e.g. with DRI2.
This moves the GDK_ALWAYS_USE_GL env var to GDK_GL=always.
It also changes GDK_DEBUG=nogl to GDK_GL=disable, as GDK_DEBUG
is really only about debug loggin.
It also adds some completely new flags:
software-draw-gl:
Always use software fallback for drawing gl content to a cairo_t.
This disables the fastpaths that exist for drawing directly to
a window and instead reads back the pixels into a cairo image
surface.
software-draw-surface:
Always use software fallback for drawing cairo surfaces onto a
gl-using window. This disables e.g. texture-from-pixmap on X11.
software-draw:
Enables both the above.
The Mir backend was checking for button mask changes to generate the appropriate
GDK event. When Mir generates a touch event it has no button mask. In this case
we'll just generate a primary button event.
This was unnecessarily creating a framebuffer in the texture case,
and it was not properly setting up a framebuffer with the texture
as source in the software fallback w/ texture source case.
Commit afd9709aff made us keep impl window
cairo surfaces around across changes of window scale. But the
window scale setter forgot to update the size and scale of the
surface. The effect of this was that toggling the window scale
from 1 to 2 in the inspector was not causing the window to draw
at twice the size, although the X window was made twice as big,
and input was scaled too. Fix this by updating the surface when
the window scale changes.
We need to use this in the code path where we make the context
non-current during destroy, because at that point the window
could be destroyed and gdk_window_get_display() would return
NULL.
The child property setting must be prepared to deal with any
child property for any child, even if it doesn't make sense,
like the pack-type for the custom title. This is happening
in glade when undoing a change in the custom-title property.
When a GtkRadioButton has no focus, it will accept it when there is no
other active button in its group.
If the active button in the group is hidden, for example because the UI
desires not to have a default option pre-selected, currently the focus
will not be accepted, which is not desired behavior.
This commit changes the code to only consider visible buttons in the
group when checking whether another button is active.
https://bugzilla.gnome.org/show_bug.cgi?id=739474
Stop using activate-on-single click for the property list -
it is a little annoying to have the popover come up when you
just click in the list to get the focus there.
This restructures the way buffers are allocated and bound in a way
that is more flexible.
Buffer operation happens in three phases:
create_buffer() - Creates the gl objects
allocate_buffers() - Allocates space for the buffers at a given size
attach_buffers() - Attaches the buffers to the framebuffer and makes
the framebuffer the default drawing target
And destroy via
delete_buffers()
We call all these the first draw, and after that we allocate buffers
each time the widget changes size until the buffers are deleted.
We delete the buffers at unrealize.
However, anyone that wants to manually control buffer allocation strategies
can manually call allocate/delete_buffers().
There are also some other changes:
* Support for stencil buffers.
* A manual render mode where ::draw doesn't render unless you manually
invalidated the previous rendering.
This moves the code related to the frame sync code into
the is_attached check, which means we don't have to ever
run this when making non-window-paint contexts current.
This is a minior speed thing, but the main advantage
is that it makes making a non-paint context current
threadsafe.
This is not really needed. The gl context is totally tied to the
window it is created from by virtue of sharing the context with the
paint context of that window and that context always has the visual
of the window (which we already can get).
Also, all user visible contexts are essentially offscreen contexts, so
a visual doesn't make sense for them. They only use FBOs which have
whatever format that the users sets up.
We had some code that tried to reuse the context over realize, but
that doesn't work as we need to share with the possibly new
paint context of the re-realized window.
To properly support multithreaded use we use a global GPrivate
to track the current context. Since we also don't need to track
the current context on the display we move gdk_display_destroy_gl_context
to GdkGLContext::discard.
Removed bright translucent outer border for "top level" osd widgets,
insensitive osd entry styled, more meaningfull color variables and
some code rationalization.
We used to have a weak ref to the cairo surface and it was keep
alive by the references in the normal windows, but that reference
was removed by d48adf9cee, causing
us to constantly create and destroy the surface.

We want to create windows with the default visuals such that we then
have the right visual for GLX when we want to create the paint GL
context for the window.
For instance, (in bug 738670) the default rgba visual we picked for the
NVidia driver had an alpha size of 0 which gave us a BadMatch when later
trying to initialize a gl context on it with a alpha FBConfig.
Instead of just picking what the Xserver likes for the default, and just
picking the first rgba visual we now actually call into GLX to pick
an appropriate visual.
Add a menu-name property and use it in a default implementation
of ::clicked to switch menus if we are inside a stack. This means
GtkModelButton is no longer entirely generic, but rather expects
to be used inside a GtkPopoverMenu. It still works in other contexts
too, of course.
Rename the "toggled" property to "active", since that is what
GtkActionHelper expects to update for check and radio actions.
Also make the property readable, since GtkActionHelper wants
to read it.
The visuals are typically sorted by some sort of "most useful first"
order. And picking the last one is likely to give us the weirdest
matching glx visual.
Under wayland, the compositor doesn't have a 'overall window alpha'
knob, we just need to add the alpha to the buffers we send.
Client-side alpha, if you want to call it that.
Implement this by reusing the existing alpha support for non-toplevel
widgets. As a side-effect of the implementation, windows with RGBA
visual under X will now also use per-pixel alpha, instead of
overall alpha.
The differences between the mutter and GTK+ code are subtle, but it
turns out that _gtk_cairo_blur_compute_pixels actually returns the
shadow *spread*. Since we use a triple box blur, the constant was
multiplied by 1.5 to approximate three chained box blurs. Split this
out and use the correct value for the lobe width.
We weren't passing in the right "d" value, which was causing the blur to
behave incorrectly, especially in the case of 1px blurs, which would
cause no blurs at all.
The blur should now match the web.
We don't want separators in both side of an iconic section
and use a 10px margin to separate two iconic sections.
Separators are also updated in case of dynamic insertion
( often used with menu items for plugins )

Commit 30a1c4ab fixed several memleaks including one in
gtk_font_chooser_widget_find_font.
However, the fix causes one extra call to gtk_tree_model_iter_next()
after finding the font we look for (ie pango_font_description_equal
returns TRUE): the 'increment' part of the for loop
(gtk_tree_model_iter_next) is run before the 'exit condition' of the for
loop is evaluated.
This commit reverts this part of commit 30a1c4ab and adds an extra
call to pango_font_description_free in order to fix the leak.
https://bugzilla.gnome.org/show_bug.cgi?id=739111
When using GtkFontChooserButton, the same GtkFontChooserWidget can be
hidden and shown multiple times. When doing that, the font that was
chosen the previous time should be the selected one in the
GtkFontChooserWidget, however this does not work as expected and a
somehow 'random' font gets selected (or none) instead.
Every time the font chooser widget is shown, its style will be updated,
causing gtk_font_chooser_widget_style_updated and then
gtk_font_chooser_widget_load_fonts to be called.
gtk_font_chooser_widget_load_fonts starts by clearing the GtkListStore
listing the available fonts, repopulates it, and then makes sure the
current font is selected.
However, this does not work as expected, as during the call to
gtk_list_store_clear, the cursor_changed_cb will be invoked multiple
times when the GtkTreeView cursor gets moved when the line where the
cursor currently is gets removed. This will cause the 'current font'
state (priv->font_desc) to be unexpectedly modified, and when
gtk_font_chooser_widget_load_fonts tries to reposition the cursor to the
'current font', we won't get the expect result.
This commit avoids that by making sure cursor_changed_cb does not get
called when we call gtk_list_store_clear in
gtk_font_chooser_widget_load_fonts.

Commits 314b6abbe8 and eb9223c008 were ignoring

that (since 2003 !). Fix things up by storing the final col
value in a separate variable and using that after the loop.

Failure to do so results in custom styling leaking through in
the inspector. This is pretty obvious, now that the inspector
is using a separate display connection and is generally isolated
from style changes.
In various places, the broadway backend was just using
the default display and assumed that it is the broadway
display. That may not be the case in a multi-backend world,
so instead iterate over all displays and use the first
broadway display - still not perfect, but enough to survive
for now.
When the window is on a non-default screen, popover_realize
ended up passing a visual and a parent_window from different
screens into gdk_window_new, which doesn't work. Fix it by
using the visual of the parent window.
GtkStyleContext was not properly handling the style cascade when
setting a screen, causing the inspector global CSS to affect the
inspector window, even though the inspector is using a different
screen now.
This helps isolate the inspector from some of the changes that
it can trigger. To specify a different display, set
GTK_INSPECTOR_DISPLAY to the name of the display to use for
the inspector window. If no display is specified, GTK+ will
use a separate connection to the default display.
When a new screen is set on a window, we unrealize it, to
recreate all the resources. But we don't reset the client_decorated
flag, so realize() doesn't call create_decoration() - which makes
sense, since the decoration already exists. But the side-effect
of create_decoration() is to select the rgba visual, and visuals
are per-screen.
Fix this by looking for the rgba visual in set_screen(), and
replacing it with the rgba visual for the new screen, if necessary.
This special code was added back in the days when computation wasn't

The gtkglarea and sidebar demos have been added, so build them in the

Patches have been submitted to the libepoxy project so that it can be built
under Visual Studio. This will allow the GDK, GTK and gtk3-demo projects
to build, but the gtkglarea code is not usable at this time as

The current implementation of this script generate headers with \x-escaped

... and make it the default. This takes over the meaning from "none" for
this property in that it draws the fallback builtin image.
"none" now literally means no image will be drawn.
This commit adds a mode to GtkScrolledWindow in which it puts
narrow, auto-hiding scrollbars over the content, instead of
allocating room for the scrollbars outside of the content. We
use traditional scrollbars if we find a mouse or if overlay
scrolling has explicitly turned off.
For test purposes, GTK_TEST_TOUCHSCREEN can be used to get
overlay scrolling even in the presence of a mouse. The
environment variable GTK_OVERLAY_SCROLLING can also be used
to force overlay scrolling on or off.
This is just meant as a prototype for how we can show a
scroll position indicator for touch. This uses GTK_POLICY_EXTERNAL
to hide the scrolled windows scrollbar while still allowing
scrolling.
This will be used to identify a scrollbar is being dragged - we
don't actually need the style class; another way to keep track
of the dragging status would be ok too.
When a getter function (like get_color()) is called and the passed in
state doesn't match the current state returned via get_state(), we used
to do a trick: We called save()/set_state() on the context before
getting the values.
Unfortunately, since 3a337156d1 this
has the unfortunate side effect that it also creates a child element.
This breaks various old codebases (spinbutton has been fixed in
998feeb2bc, Webkit is fixed in
https://bugs.webkit.org/show_bug.cgi?id=137803 ) unfortunately.
So instead, look up the values manually ensuring that no child element
is created but the correct state is used.
Keeping them is a bad idea now where the widget paths are actually
changed by a save(). And almost all of the time, state or style classes
will be changed anyway.
Looking them up again is just a hash table lookup anyway.
GtkCssNodeDeclaration is a new struct with copy-on-write semantics.
It encapsulated the properties used to define a node in the CSS tree.
The idea is to use it in various places for caching, in particular as
key in hash tables.
This signal is emitted whenever user scrolling hits the overshoot
edge in the given direction. May be useful to add "reload" or "load

When gtk_window_set_titlebar (win, NULL) is called, we were taking
an early exit and forgot to re-map the window. This does not normally
happen in practice, but glade is about to get a 'csd' switch which
lets one toggle back and forth between titlebar and no titlebar.
With the recent save-is-child changes, using
gtk_style_context_get_padding (context, different_state)
will now open a subelement.
This is not what we want, so we check the state whenever we get the
button contexts.
Now it's based of fg color, so the list row gets darker on the
bright variant and brighter on the dark variant, similarly to what
we do for spinbutton buttons.
Flat buttons gets the button decoration on hover, while transitioning
the decorations of adiacent flat buttons are both shown (one fading in
and the other fading out) so the borders clashes, since normally there's
no spacing between them, to avoid it the transition on the normal state
is set to none and added back to the hover state, so the decoration
won't fade out. To make the transition more evident the duration is
increased.
This is mostly useful for fallback testing.
I suppose if people want finer grained GL ability testing, they can use
Mesa environment variables to tune things.
This is a change for how CSS is applied.
Previously, subelements (I'll take GtkEntry icons as an example) were
treated as having the same parent as the regular elements. So a selector
such as
.entry
would match an entry inside a window. But it'd also match the icon image
inside the entry. So CSS like
.entry { padding: 10px; }
would add 10px of padding to both the entry itself and to the icon image
inside the entry, so the icon would effective have 20px padding. To get
around that, one would have to unset it again like so:
.entry { padding: 10px; }
.entry.image { padding: unset; }
This is getting more and more of a problem as we make subelements
respect more properties that aren't inherited by default anyway, like
backgrounds and padding/margin/border.
This patch has one caveat though: It makes calling
gtk_style_context_save() the first time have an important side effect.
It's important to audit code to make sure it is only used for
subelements.
And last but not least, this patch is only useful if code unsets
parent's style classes that it doesn't want to apply any longer. Because
style classes are inherited by default (and I don't think we want to
change that), the example will still apply until the subelements no
longer contain the .entry style class.
If the menubar has an app-menu popover, and it is shown at the time of
disposing the window, it will attempt to transfer focus back to the
previous focus widget when undoing modality, even though the dispose()
code already did set_focus(NULL) previously.
At the time the popover is removed, there aren't many hints as to whether
the toplevel or the focus widget are being destroyed (ie. not still under
in_destruction), so just swap the order of these two calls.
For every other popover, this would all happen within dispose/destroy,
which is handled better.
This way we don't have to clear/refill the model every time but can keep
the existing model and only update the values.
A nice side benefit is that running an update keeps the current selection.
Its not really reasonable to handle failures to make_current, it
basically only happens if you pass invalid arguments to it, and
thats not something we trap on similar things on the X drawing side.
If GL is not supported that should be handled by the context creation
failing, and anything going wrong after that is essentially a critical
(or an async X error).
We make user facing gl contexts not attached to a surface if possible,
or attached to dummy surfaces. This means nothing can accidentally
read/write to the toplevel back buffer.
This adds the new type GdkGLContext that wraps an OpenGL context for a
particular native window. It also adds support for the gdk paint
machinery to use OpenGL to draw everything. As soon as anyone creates
a GL context for a native window we create a "paint context" for that
GdkWindow and switch to using GL for painting it.
This commit contains only an implementation for X11 (using GLX).
The way painting works is that all client gl contexts draw into
offscreen buffers rather than directly to the back buffer, and the
way something gets onto the window is by using gdk_cairo_draw_from_gl()
to draw part of that buffer onto the draw cairo context.
As a fallback (if we're doing redirected drawing or some effect like a
cairo_push_group()) we read back the gl buffer into memory and composite
using cairo. This means that GL rendering works in all cases, including
rendering to a PDF. However, this is not particularly fast.
In the *typical* case, where we're drawing directly to the window in
the regular paint loop we hit the fast path. The fast path uses opengl
to draw the buffer to the window back buffer, either by blitting or
texturing. Then we track the region that was drawn, and when the draw
ends we paint the normal cairo surface to the window (using
texture-from-pixmap in the X11 case, or texture from cairo image
otherwise) in the regions where there is no gl painted.
There are some complexities wrt layering of gl and cairo areas though:
* We track via gdk_window_mark_paint_from_clip() whenever gtk is
painting over a region we previously rendered with opengl
(flushed_region). This area (needs_blend_region) is blended
rather than copied at the end of the frame.
* If we're drawing a gl texture with alpha we first copy the current
cairo_surface inside the target region to the back buffer before
we blend over it.
These two operations allow us full stacking of transparent gl and cairo
regions.
This is a new function that gets called every time we're drawing
some area in the Gtk paint machinery. It is a no-op right now, but
it will be required later to keep track of what areas which
we previously rendered with GL was overwritten with cairo contents.
First of all we track the current update area during an
update in window->active_update_area. This will be used later
in end_paint to know the damaged area.
Secondly we keep track of old update areas for the last 2
frames. This will later allow us to reuse old framebuffer
contents in double or tripple buffer setups, only painting
what has changed since then.
If we want to use OpenGL in GDK then we have two choices; either:
- find the GL headers on each platform
- do extension discovery
- implement all the crazy dlopen()/dlsym() dispatch tables
*or* use libepoxy, which shields us from all this madness and provides a
decent layer for GL clients to use, without creating its own namespace.
Epoxy is also used by other projects, like Xorg and piglit, and it's
portable to all the platforms GDK cares about.

Before 5e325c4, the default BitGravity was NorthWestGravity.
When static gravities were removed in 5e325c4, the BitGravity regressed
to the X11 default, Forget. Forget causes giant graphical glitches and
black flashes when resizing, especially in some environments that aren't
synchronized to a paint clock yet, like XWayland.
I'm assuming that the author assumed that the default of BitGravity was
NorthWestGravity, which is the default of WinGravity. Just go ahead and
fix this regression to make resizing look smooth again.

The last change accidentally removed the later restore, and

Currently writing wl_data_offer data into the fd is 1) synchronous, which

We want to render a background *and* the current color (if there is

This also adds a custom function gtk_render_add_content_path() which

This is a convenient shortcut for a common case. It is implemented
by adding a .monospace style class to the text view, and letting

Same here: We need to synchronize the visible child with the
selected row when setting a stack on the sidebar. I've noticed
this problem in the sidebar example in gtk3-widget-factory.
The documentation explicitly states that 0 is an allowed value for using
the same scale as the window. This 0 value is also explicitly checked
down in the call chain and handled.
Drawing text with Pango is quite expensive, and drawing text and also
blurring it is *really* expensive. To prevent us from drawing a lot of
text and then blurring it a lot is *really* expensive.
We now cache the blurred pixels for the last layout and shadow we made,
which means we can repeatedly draw labels with a blurred text-shadow
extremely fast.
To detect whether the shadow is up-to-date, we track the serial of the
PangoLayout alongside the radius of the box shadow. We don't support
inset shadows nor spread on text-shadow, so we don't need to track
these.
There is no need for a critical warning just because somebody

We get multiple notifications from the bookmark manager when
something changes. Every time, we reconstruct the sidebar contents
completely, by clearing the store. The bookmarks are added with

async requests, leading to multiple instances of the same bookmark
getting added. Use the cancellable we already have to prevent that.
This could be made much more efficient by not recreating the entire
sidebar quite so often (3-5 times for a single bookmark rename).

Parent is guaranteed to not be NULL. It can only ever be NULL for root

"Well, it just looks like black text on a white background."
"You mean it's the same as if we just duplicated the text?"
"Yeah!"
"Hrm, maybe we can put a frame around it."
"Sounds good. I'll stuff the textviews in a GtkFrame."
"What? Why? Let's use a GtkEventBox and override its background"
"Why is that a good idea when we have GtkFrame?"
"Because I said so!"
"Okay."
Overriding the background color for a color swatch is wrong. The color
is not the background, it's the foreground, so it should be painted in
a draw signal handler.
- gtk_style_context_get_background_color()
- gtk_style_context_get_border_color()
Those functions shouldn't be used anymore, because they don't represent
anything from the CSS styling we support. The background color often
isn't used due to background images and there are actually 4 different
border colors (1 for each side) - if there isn't also a border image in
use.
Instead of drawing a gradient in the background color, draw a CSS box.
And change the theme so instead of setting just a background color it
draws a gradient.
The resulting visuals are the same.
Instead of drawing text for selections and links manually, use the
gtk_render_background() and gtk_render_layout() functions.
As a side effect, this allows shadows on selected text and links
and real backgrounds (like gradients or images), too.
I tried asking but nobody knew why it is necessary to set the background
color of the first cell. It seems with CSS styling this is completely
unnecessary.
This fixes shadows that are animated not updating the clip of the widget
they are drawn on. An example of this are the buttons in the CSS shadows
example in gtk-demo.

broken in this scenario.
Fix this by always placing the main part directly under

The warning may have had some value at some point, but if
people uninstall large icons just to make the warning go
away, it does more harm than good. So just remove it.
Context menus inherit their style from the widget they are attached
to. This can have unexpected effects in particular for font, as can
be seen in gedit or gnome-calculator. Prevent this by resetting
the font of context-menus to the initial value.
GtkSidebar behaves internally much like GtkStackSwitcher, providing a vertical
sidebar like widget. It is virtually identical in appearance to the widget
currently used in GNOME Tweak Tool.
This widget is connected to a GtkStack, and builds its own contents as a
GtkListBox subclass, using the "title" child property to provide a consistent
navigatable widget.
Being a subclass of GtkListBox it benefits immediately from strong keyboard
navigation, and minimal changes are required for theming.

Add some docs/example about the possible event handling ordering issues
that may appear on GtkGesture::begin between multiple gesture groups.
Mostly relevant for state changes.
The remaining code assumes that the dialog doesn't get destroyed, but
it actually does on delete-event.
In particular, the filter function and the preview text are lost as
soon as the dialog is created and thus when we create a new dialog we
don't have those properties to set on it anymore.

The scale in the selectable listbox in page 2 of gtk3-widget-factory
has the flaw that the row is getting selected even when one only
interacts with the scale - unlike e.g. the checkbutton and button
further down in the listbox.
The problem is that GtkRange is trying to claim the sequence for
the drag gesture from the ::pressed handler of a multipress
gesture. Since the drag gesture hasn't seen the sequence at this
point, that is ineffective.
The fix here is to rearrange the gestures so that the multipress
gesture sees the sequence before the drag gesture, and then
claim the sequence from the ::drag-begin handler.
Binding signals can return a boolean indicating whether they
handled the event. Use that here and return FALSE if the
inspector keybinding is disabled.
Loading a builder file with a window leaves a ghost behind, since
windows need to be explicitly destroyed. Avoid that by using
gtk_builder_add_objects_from_resource.
When closing the inspector before the main window, we must take
care to sever all signal connections and weak refs, otherwise
things will go bad when the window is closed later.
When GtkGestureMultiPress::released happens, in_button should be unset
after emitting GtkButton::released, whose default implementation uses it.
Moreover, in_button should only be unset there for real touch events, not
guaranteed to trigger crossing events, as opposed to every pointer/touch
events from touchscreens.
https://bugzilla.gnome.org/show_bug.cgi?id=737297
Instead of hardcoding these actions, consult the settings.
Note that not all of the actions supported by gnome-shell are
implemented here, only maximize, minimize, lower, and menu.
https://bugzilla.gnome.org/show_bug.cgi?id=729782
These match the GSettings that mutter/metacity/gnome-shell have
for this. We change the default for the middle-click action to
none, since lower is just a terrible default.
We're slightly bending the rules here, since we're adding new
settings after .0, but a) it is just barely after .0, and b) settings
are not really application API.
https://bugzilla.gnome.org/show_bug.cgi?id=729782
Some recent refactoring changed things so that in_button is no
longer TRUE when released() is called for touch events. As a minimal
fix, let GtkButton do more of the work by chaining up to its
pressed and released handlers, which know how to handle touch
events. This could be further improved by leaving more of the
state handling to GtkButton, like it was done for GtkToggleButton.
If we have a fullscreen window that covers a monitor, desktop

A popover can go unmanaged for 2 reasons, when the widget it points to
gets destroyed, or transitionally in gtk_popover_set_relative_to(). In
both of these cases it makes sense to only unset popover information
about the previous widget managing it, if the popover is meant to
survive the unmanaging through extra refs.
Also, the focus widget prior to a modal popover being shown is considered
information about the relative_to widget, unset it on
gtk_popover_update_relative_to() with the rest.
https://bugzilla.gnome.org/show_bug.cgi?id=736193
This gives an opportunity for implementations to handle these events
differently, instead of hardcoding the WM-triggering behavior.
gtk_window_event() only forwards events for WM management if the event
widget is not the window (ie. caught when bubbling), so is safe to be
called here without triggering gtk_window_handle_wm_event() twice.

If !owner_events, the pointer window has been usually set to NULL if
the pointer fell outside the grabbing widget, but it was not being

On regular scrolling (ie. not natural scrolling), positive deltas in the
Y axis (downwards) should actually move the value towards the adjustment
minimum value to be more intuitive. This also makes the scrolling

Windows needs a shared library to link the modules against, otherwise
the undefined symbols make it not work.
So build a shared library on Windows.
We don't want a library elsewhere, as that just complicates things, so

For symbolic icons, we prefer symbolics in inherited themes over
generic icons in the theme itself. So far this was implemented
by looking at icon_name[0] and looking that up in inherited themes
if it is symbolic. But with automatic rtl/ltr handling, the first
icon name will always have an -rtl or -ltr suffix, and an icon
with that suffix is not going to exist in most cases. To fix this,
look for shorter icon names too, as long as they are still symbolic.
https://bugzilla.gnome.org/show_bug.cgi?id=737000
This is a noinst library for now, but the idea is to turn it into a
proper DLL on Windows, so that we can install it and properly link the

Otherwise, they might not be properly set before the window is mapped.
For the opaque region and border window, it means that they won't get
set before the next size allocation, which tends to not be a bit deal.
For the shadow width, though, _GTK_FRAME_EXTENTS has a different meaning
when it's set before the window is mapped, so we need to make sure that
it's properly set when the window is mapped.

This updates the property sheets that are used to "install" builds of GTK+
after the libraries and the gtk3-demo programs are built. Note that these

move the header installation part to use autocompletion by the autotools

This allows us to access otherwise hidden windows, which can be

The list of devices was being scanned over incorrectly, causing us to
never actually fetch the keymap from the keyboard, as the keyboard was
the second device in the list, not the first.
This causes us to create a new temporary keymap every time, which is
quite expensive, because it involves parsing the entire XKB
file. Scanning the list correctly will cause us to use the XKB rules
file that was passed to us.
The "too dark" background was caused by box-shadow inherited by

This is a temporary workaround for scrolling units being amplified

Those used to work indirectly due to GtkEntry not setting GDK_TOUCH_MASK,
so pointer emulation would happen on those, but the event handlers on icons
and its icon-pressed/released signals have never been explicitly touch
aware, and this broke since the GDK_TOUCH_MASK can be set indirectly by
GtkGestures.
So make the icon event handler handle touch events, each icon can get hold
of one GdkEventSequence, reacting exclusively to it. This is still not
ported to GtkGesture due to GdkEvent exposure in these icon signals, as
users might expect GDK_2/3BUTTON_PRESS while GtkGesture ignores those.
Also, unset all icon pressed/sequence state on grab-notify, this used to
happen ad-hoc when initiating icon DnD, but that doesn't cut it for
user-defined reasons to initiate a grab (eg. popovers).

Using the setting for this property conflicts with the documentation

The entry mixin now allows to specify the color of the widget bottom

When recursing the update area down into native subwindows we forgot

Tools like damn-lies rely on being able to generate .pot files
from pristine checkouts, so everything that goes into the .pot
file has to be in git. This is not ideal, but we already do
the same for other .ui.h files in GTK+.
Otherwise, git.mk will add them to .gitignore, and we want to
add them to source control for the benefit of tools like damn-lies
which rely on being able to generate a .pot file from a pristine
checkout.,
A surface may be hidden when a frame is already scheduled, which may cause

Only static cursors are supported in gdk_device_grab() so far. Obey the

cursor will be restored as usual.

On DnD, pointer_handle_leave may be triggered without the pointer actually
leaving the window, and pointer_handle_enter() happening after intra-window
DnD won't actually manage to update the cursor (it does nothing directly,
and to the upper layers the cursor is still the same and consistent, so no
attempt will happen).
To fix this, keep the pointer cursor on leave, and ensure it is updated
on enter. The pointer cursor will be updated to any current new one through
the enter/motion events generated if it needs be.

cairo_surface_destroy() is called after the buffer is released, for every
wl_buffer. Windows usually reference their cairo surface before rendering,
so that extra reference is consumed after the buffer is released, so do
the same with cursor surfaces and add an extra reference whenever a cursor
surface change is about to be scheduled.
Otherwise, the GdkWaylandCursor is left with an invalid cairo_surface_t,
which causes crashes the next time it is used.

This must be called while the window is not realized yet, and sets the

Subsurface position is deemed part of the state of the parent surface, so

The pre-gestures code used to compare the current button press with the
previous one on !activate_on_single_click, and unset the previous event

Since GLib ≥ 2.41, attempting to release an unlocked mutex will abort(),
as it happens on most systems already.
Given the lack of proper documentation on how to use GDK with threads,
there is code in the wild that does:
gdk_threads_init ();
gdk_init ();
...
gtk_main ();
instead of the idiomatically correct:
gdk_threads_init ();
gdk_threads_enter ();
gtk_init ();
...
gtk_main ();
...
gdk_threads_leave ();
Which means that gtk_main() will try to release the GDK lock, and thus
trigger an error from GLib.
we cannot really fix all the wrong code everywhere, and since it does
not cost us anything, we can work around the issue inside GDK itself, by
trying to acquire the GDK lock inside gdk_threads_leave() with
trylock().

gtk_css_section_get_end_position() can return a position one byte beyond

adds tracking of the fullscreen mode if externally modified, as well
as toggling the native fullscreen mode of the window as needed.
The timeout ID used to be unset after we got the targets from the
clipboard, but there's still a moment between the clipboard request and
the GDK_SELECTION_NOTIFY event that the ID points to an already gone
timeout.
There is an insensitive label in widget-factory which was
not getting any different from the sensitive label next
to it. With this patch, it does, again.
Use U+00D7 MULTIPLICATION SIGN and U+200A HAIR SPACE instead of plain
old 'x' and ' ', following https://wiki.gnome.org/Design/OS/Typography.
Sadly, many fonts don't have space variations, so Pango/harfbuzz fall
back to using the regular space glyph anyway.
NULL was returned in case of an empty last line. Every users needed to
special-case this. Now it will return the expected result: char_len of 0
with one PangoLogAttr.
In compute_log_attrs(), 'paragraph' will be the empty string "" with
'char_len' == 0.
pango_get_log_attrs() works fine with an empty string, it will return
one correct PangoLogAttr (because there is one text position for the
empty string).
It fixes the unit tests for gtk_text_iter_is_cursor_position().

There was some confusion between unflipped and flipped positions.
Both final_position and current_position are meant to be unflipped,
and get_effective_position() needs to be applied to them to get
a flipped position. _gtk_window_set_popover_position() also expects
an unflipped position.

This was introduced as a hackish way in 3.6 to make font updates
propagate properly. But since then, font handling has been changed and
this flag is no longer necessary.
gtk_style_context_invalidate_internal() will respect only the current
saved state of the style context, which is wrong when updating the scale.
In that case, the whole style context needs updating.
- only one blank line is enough to separate code sections.
- the 'signals' variable was in the middle of function prototypes.
- compare pointers to NULL in some conditions ("if(blah) should be used
only if blah is a boolean variable). It makes the code clearer.
- various other things.
This is a hack to get around the optimizations done by the CSS engine.
The CSS engine will notice that no CSS properties changed on the
widget itself when going from one state to another and not queue
a redraw.
And the reason for no properties changing will be that only the
checkmark itself changes, but that is hidden behind a
gtk_style_context_save()/_restore() pair, so it won't be caught.
This is more for GTK developers to catch when they forgot to change
GTK_STATE_FLAGS_BITS after adding a new state flag than to prevent
widget developers from using the wrong flags.
This was a hack we added in early 3.x to allow themes to customize their
checkmarks.
Now that we want to properly support real backgrounds everywhere,
supporting this feature would cause double draws of backgrounds.
... in places where we draw a background. This was changed for GTK 3.0.0
to allow animations, but these days it doesn't make sense anymore to use
gtk_render_activity() for backgrounds.
All buttons should always be marked as :active when they are pressed.
That includes checkboxes (which are never activated in real code anyway,
so this change pretty much doesn't matter).
It doesn't make sense to support child displacement in a world where
pseudoclasses behave different from the actual displacement states.
Nobody would ever understand why a widget is displaced.
It is easily possible to simulate child displacement by using padding
CSS properties.

- GtkToggleButton
- GtkCheckButton
- GtkRadioButton
- GtkModelButton
- GtkCellRendererToggle

- Adwaita
- Raleigh

The new :checked state replaces :active for the actual checkedness of
the widgets and :active is now used exclusively while the button is being
pressed.

The font chooser constructs the display name for the font from
the family and face names. Do the same in the font button, so
we don't end up calling the same font by different names, which
would be confusing.
Instead of reconstructing a display name from the
PangoFontDescription, use the font family and face
objects, which have the original font. This lets us
get the names of fonts like Noto Sans CJK DemiLight
right, which would be shown as Noto Sans CJK SemiLight
when mangled via PangoFontDescription, since Pango
treats 'DemiLight' as an alias for the SemiLight weight.

gtk_statusbar_remove_all() was popping the top message if its

Changing adjustment via the property setter would not emit
value-changed, however changing it via gtk_spin_button_configure would.
This inconsistency had the following side-effects:
- Setting an adjustment with a different value would not update the
value shown by the spin button.
- Creating a spin button like this (common in GtkBuilder XML) will
not show the initial value:
g_object_new (GTK_TYPE_SPIN_BUTTON, "adjustment", adj, NULL);
Let's use the same code path (ie. gtk_spin_button_configure) for all
public facing API for setting adjustment. The code that handled the
details of swapping out the old adjustment with the new has been split
into an unset_adjustment method and the rest has been folded into
gtk_spin_button_configure.
A spin button really needs an adjustment to work, so we don't need
most of the NULL checks. However we do need to check in
unset_adjustment because setting a new adjustment during object
creation might try to unset a non-existent one.

As a noinst_PROGRAMS, the libtool generated for cross-compiling will be
used, which will mess up the linking. Create a all-local target instead.
Also ensure that building uses always a native version of the tool by
specifying a GTK_UPDATE_ICON_CACHE automake variable.
Finally "config.h" has been created to work for the target platform and
causes problem when cross-compiling. So we temporarily generate a basic
config.h which contains only the strict minimum.
It is actually a bad idea to use noinst_PROGRAMS for build tools,
because it adds a $(EXEEXT). It is best to override the all target
with all-local to trigger the tool build.
When using the pre-rendered png symbolics it seems that we're off a
tiny bit in a few of the pixels on the antialiased borders of a
stroke. To fix this we switch the icon to media-playback-stop-symbolic
which has no such antialiased borders.
I don't quite understand why the pixels are off, this needs more
research.
https://bugzilla.gnome.org/show_bug.cgi?id=734668
If the foreground color has an alpha != 1 we used to just pass that into
the svg. This is useful to e.g. render an insensitive icon. However,
that is not an ideal model for symbolics. For instance, if the icon uses
overlapping areas when drawing, expecting these to be opaque then the
transparent color will result in a different alpha value for the overlapping
area. Also, non-foreground symbolic colors are still rendered opaque, and
the recoloring of pngs can't handle transparent colors.
So, instead we extract any alpha from the foreground, render using the
opaque colors and then apply the foreground alpha to the entire result.
This means we get an even transparency, even for other colors, and we
can apply alpha for the pngs too.

_gtk_icon_helper_get_size() is often used during size request and may
not necessary mean that the icon will be displayed immediately. In
many common cases we know the size without having to ensure a surface.
In many cases this means we can avoid loading an icon until needed, and
in the case of stateless IconHelpers such as GtkCellRendererPixbuf this
is very important as otherwise it will constantly be reloading icons
if the displayed set is larger than the in-memory icon cache.

This check used to be present in the pre-gestures code, but was unintentionally

This was another victim of clipping changes - the labels were
overdrawing each other, leading to test failure. Prevent this
by separating the grid columns.
I found that setting margins to zero makes the textview clip

do this test with a 2/8 split of margins, to avoid the clipping

AM_PATH_GTK_3_0([3.4], [], [], [gthread]) results in calling

For that to happen the libgtk3 is embedded with a manifest that requests
common controls library 6.x, and GTK lazily calls InitCommonControlsEx()
to initialize those. Then this manifest is used to temporarily override
the process activation contest when loading comdlg32 (which contains the

controls 6.x, even if the application that uses GTK does not.

It is bad if the image that is used as a fallback for missing
images goes missing itself, so include it as a resource. This
way, it will always be available.
The rules-hint property has always been a fairly bad application API, as
it set some wrong expectations for the developers; deferring to the
theme makes it impossible to design application reliably, and if this is
a usability setting we should either impose this setting on every theme,
or simply drop it.
Our own default theme does not honour the zebra striping, which makes
this function even more questionable.
In practice, usability studies on zebra striping have demonstrated that
alternating colors on a list it improves readability just as much as
clear ruling between rows, or by visually differentiating the selected
row. Zebra striping improves readability (or, at least, it does not
hinder it) on static displays, like a table on paper or a document; on a
dynamic display, like an application's UI, there are different
strategies that yield similar, if not better, results.

It turns out that when we were painting the shadows, we painted the them
with the base color once, which contained the alpha, and then blurred it
and used it as a mask for the fill, which has the fill again.
To fix this, always paint the base surface with full alpha. The existing
code applies the blur conditionally sometimes in weird ways, so the code
shuffling fix may not look correct, but be assured it is. If the blur
happens, the new cr we return has the *default* color applied, which is
fully opaque black, which works perfectly against the A8 surface.
The fallback spinner code needs some modification, since it is
intentionally using the alpha to paint the lobes which are "in the past".
Since we shouldn't be hitting this fallback path very often, we use a
temporary group and paint it with paint_with_alpha, even though it is
slow.

Use (cairo) input shape of the window to check whether a point is inside or not

Don't do any of the above if the window has CSD-incompatible styles (WS_BORDER

This allows subclasses to render things below and above the text

work anymore since the view now renders a background, and due to the

This was silently broken - the code was just assuming that the

For images without a concrete size but with an aspect ratio, we took the
wrong code path.
(I even copied the documentation that said "Otherwise" but didn't put an
else clause there, go me!)
The widget path code copies elements only in gtk_widget_path_copy() -
which is essentially unused - and in
gtk_widget_path_append_with_siblings() - which is used by GtkBox.
So stuff the widget we are testing in a GtkBox to reroduce the problem.
Now that widget paths are allowed to have a state, use that state when
querying style properties. This uses a fast path in gtkcssprovider.c and
that is great.
Header-bar and action-bar buttons used to be bigger then others
now everything is as big as those, maintaining two different sizes
for default widgets depending on the placement is a maintainance
nightmare and having controls the same size is good from a usability

With this, Ctrl-Q will close the window, and Ctrl-D will
toggle the dark theme. The accelerators are currently not

Fix that by setting halign to fill. To keep the menu label
left-aligned, set xalign to 0 to compensate.
Make gtk_widget_path_append_for_widget() add the state flags of the
widget, too.
This enables the ability to select pseudoclasses on all elements in a

Don't take a state when constructing the CSS matcher. Instead, rely on
the newly introduced state in the widget path.
This way, the state can be queried not only on the first element, but on
all elements of the widget path.
Set the widget path state flags with the state flags of the style
context.
We do not update the state flags but replace the previous one because we
want to be able to have save()/restore() unset state flags.
Make backdrop insensitive state more similar to the focused
windows one, mostly to make dark variant more usable and
focused -> backdrop transition less distracting.
Add left/right/top/bottom style classes according to which edge(s)
of the progressbar the progress is adjacent to. Only for a fraction

xdg-shell has moved on and replaced set_margin with set_window_geometry.
To properly support set_window_geometry requires a full rewrite of how
we've been dealing with toplevel windows for now, so just don't set any
margin until we can have a proper toplevel window abstraction in GTK+.
Don't shadow existing variables. Instead of sharing the allocation and
then overwriting the width/height when convenient, declare it in the
block we use it in, as, really, the three different paths are all
extremely different, and there's no sense in sharing the variable.
We can't avoid calling set_titlebar in buildable_add_child, since
GtkBuilder assumes that it can e.g. call grab_default at the end,
which only works if the widget is inside a toplevel at that point.
Instead, drop the titlebar and clean up priv->headerbar in constructed
if we find that we don't want a headerbar.
find_by_log_attrs() can return true only in this case:
return moved && !gtk_text_iter_is_end (arg_iter);
So if the iter moved (i.e. something has been found), but is the end
iter, find_by_log_attrs() returns false.
Now the same checks are made in find_visible_by_log_attrs(). The public
functions using find_visible_by_log_attrs() say in their documentation
that false is returned for the end iter, hence the check with
gtk_text_iter_is_end().
https://bugzilla.gnome.org/show_bug.cgi?id=618852
attrs[len] is the last PangoLogAttr available, at the iter position after the
last character of the line.
For a line in the middle or the start of the buffer, the '\n' is taken
into account by 'len'. For example the is_word_end is generally reached
before the '\n', not after. But for the last line in the buffer, where
there is no trailing '\n', it is important to test until attrs[len].
The bug didn't occur before because find_by_log_attrs() worked directly
on the iter passed as the function argument. But now it is no longer the
case.
https://bugzilla.gnome.org/show_bug.cgi?id=618852
- Return true (found) and false (not found) explicitly.
- Set found_offset only when something has been found.
find_backward_cursor_pos_func() was a bit different, the while loop had
the condition "offset > 0" but the return was "offset >= 0". Probably a
micro-optimization, since offset == 0 is always a cursor position.
Anyway now the code is the same as the other functions.
https://bugzilla.gnome.org/show_bug.cgi?id=618852
Do not work with the iter passed as the function argument. Work with
another iter, and set it back to the function argument only if something
has been found.
This fixes a few unit tests. But there are regressions for a few others.

The Adwaita icon theme ships spinners in a scalable directory
with MaxSize=32 and Scale=1. One way to make them scale up in
hi-dpi would be to add an @2 directory with MaxSize=32 and Scale=2,
but that directory would also be consulted in non hi-dpi situations
and give us an effective spinner max size of 64.
Instead, treat svg icons implicitly as hi-dpi, and scale them
up to MaxSize * 2 when in hi-dpi.
This was causing menus to show up in the wrong position in case the menu
popped up towards the top and/or left.
The change to the requisition was in error; it is the allocated size
of the menu, not the toplevel, and doesn't include the shadow.
https://bugzilla.gnome.org/show_bug.cgi?id=591258
This had originally been added to Adwaita in the gnome-themes-standard
commit 7bf01517bc2 but was lost during 3.13 theme changes, causing bug
591258 to reappear.
Like the autotools builds of the introspection files, don't include gtkx.h
in the introspection prepropcessing as it should not be included by other
GTK+ headers.
We now apply the .button style class to rows that are either
activatable or selectable. Selectable rows only get the .button
if the listbox allows selection. This implies that we need to
update row styles when the selection mode changes, or when the
row gets added to a listbox.
Having an explicit property for this will make it easier
to have a hover style only for rows which are activatable
or selectable.
Rows are selectable by default, to preserve compatibility.
It's hard to figure out what the "expected_reply" means except under
close examination -- it's actually talking about whether this was a
reply to a ConfigureRequest or not. The inversion in the check doesn't
help either.
Make the code cleaner by moving it above the freeze/thaw case, and
making the check more explicit and without a confusing variable. If we
haven't sent any ConfigureRequests out, then it must be a gratuitous
ConfigureNotify.
Some windows, like GtkWindow and some other apps, set a transparent
background. The guarantee for begin_paint_region is that there should
be a full clear to the specified background color, not a composite
against what was there before.
This fixes repaint artifacts in Wayland and Weston in a better way than
76922c169f.
Slapping file:// in front of a path does not guarantee a working
uri (e.g. if you are on windows and the path looks like F:\\...).
Therefore, go back to using g_file_new_for_path if we don't have
to deal with a resource.
It turns out that activate-on-single-click interferes with the
expected multi-selection behavior. Turn it off, since there's nothing
to activate in this list, anyway.
The animated scrolling interferes with incremental validation.
As short-term solution, disable scrolling animation during
incremental validation. This is not a proper solution, but
it avoids broken behavior like scrollbars that are not reacting
to clicks. The problem was visible, e.g. in the list view
example in gtk3-demo.

gdk_x11_display_set_window_scale() affects the interpretation of the
Xft/DPI XSETTING - it is substituted inside GDK with the value of
Gdk/UnscaledDPI xsetting. However, this change is not propagated to
GTK+ and from GTK+ back to gdk_screen_set_resolution() until the
main loop is run.
Fix this by handling the screen resolution directly in gdk/x11.
This requires duplication of code between GDK and GTK+ since we still
have to handle DPI in GTK+ in the case that GdkSettings:gtk-xft-dpi
is set by the application.

Conceptually, text handles are boxes, whose content is a 'handle',
so draw background, frame and handle. With this, and the previous
commit, the cursor-handle theming in Adwaita now works as intended.
The text handles reuse the style context from their parent widget,
and just add .cursor-handle. That means that the more specific
entry selectors override the .cursor-handle theming unless we
select for .entry.cursor-handle. We also need to work harder to
keep the .entry styling from drawing decorations around the outlines.
The listbox code relies on the container focus adjustment handling
to scroll the cursor row on screen. But GtkContainer has no idea
about row headers, so ensure that we scroll the header on screen too.
Use gtk_text_iter_set_line_offset (&tmp_iter, 0) instead of
gtk_text_iter_get_line(). The difference should not be big. In the first
case the line doesn't need to be traversed thanks to the offset 0. For
get_line(), the btree must be traversed.
A temporary iter is needed to not break the behavior. But the behavior
is quite strange, the function works directly on the iter passed as an
argument to the function, even if the function returns FALSE (not
found). So maybe a later commit will fix this strange behavior.

find_by_log_attrs() was a recursive function. It is replaced by an
iteration.
The already_moved_initially parameter was TRUE only for the recursive
call, so the paramater is removed.
There is also a small cleanup of the find_visible_by_log_attrs()
(remove trailing spaces, fix indentation).
There is still a part to optimize for a later commit.

This is fallout from the recent dialog changes. We don't set the
headerbar as titlebar early enough anymore, so when the window title
gets set, it does not get passed on to the headerbar. So, re-set it
manually when the titlebar is put in place.

This will let us theme activatable rows differently.
We also avoid emitting the ::row-activated signal for
rows that are not activatable. For compatibility reasons,
rows are activatable by default.

Move the touchscreen switch to the other debug switches, and
move the hidpi spin to the other graphical controls. Since the
Visual tab is getting large, make it scroll. The General tab
is purely informational again.
Otherwise, the CSS background we draw would be clipped if the ink rect
was smaller than the allocation (a very common thing).
Broken since 37030a7710 where we clipped
to the ink rect.
The paned examples on page 2 were implicitly relying on labels
drawing unclipped. Instead of setting the view class only on the
labels, set it on the paned's instead.
The overlap was caused by using pack-end for the arrow, which
causes it to be allocated from the other end. Avoid the problem
by using pack-start for both the title and the arrow, and
reordering them according to xalign.
... so that it works with wide separators. Or rather: with separators
that don't request 1px size but any other number. Do that by making the
placeholder request the same size by indeed stuffing (hidden) separators
in it.
Some of the features we expose can be hardcoded via environment
variables. In that case, don't confuse the user by letting them
change settings that have no effect.
The displacement animation has been replaced by edge gradients, that
have a stronger color the harder overshooting is hit. This makes it
possible to remove the internal overshoot window, which was merely
used to have contents displaced when overshooting to top/left.
Overshooting to bottom/right used to cause queue_resize() to be
called on the scrolled window, this isn't necessary anymore either.
https://bugzilla.gnome.org/show_bug.cgi?id=731297
There was this hack, taken verbatim from GtkCList according to the comment,
that would recursively translate the allocation during scrolling, and set
it on children widgets through the direct gtk_widget_set_allocation() setter.
Since commit 4f89eb05cf, this has caused the wrong clipping areas to children
widgets of a textview. The reasons for this seem lost in time, and the approach
seems indeed wrong for windowed widgets as the repositioning of those windows
couldn't happen.
So replace all of this with just a gtk_widget_size_allocate() call, which does
work ok for the children widgets embedded in the "multiple views" gtk demo, and
ought to work for every other widget.

The reparenting happening on the column header so it gets a movable

Among other things, this fixes a lack of discernible border when

The recent reshuffling caused an ordering problem where we would
hide the action area before relocating the buttons to the header
bar. But hiding makes the default button loose its defaultness.
Rearrange things so that we move the buttons before hiding the
action area, and thus preserve the default.
If the drag gesture gets a GtkGesture::updated signal, the user
is directly interacting through pointer/touch with the range slider,
animating the adjustment value change in this situation can produce
perceived lag, so set the value immediately when this is happening.
Use the adjustment target value when repositioning the cursor, and remove the
checks that ensured the cursor was made onscreen immediately, as there will
be definitely a delay on animated adjustment changes.
When moving the cursor, compare current adjustment value with the post-animation
target value, in order to avoid false "keynav failed" positives as the animation
hasn't started yet, so dx/dy are still 0 at that time.
We move our menus.ui file into Gtk's namespace so that it will get
picked up. Accordingly, we no longer have to do any of the work for

Use the new ::resource-base-path property on #GApplication to attempt to
load the menu layout of the application.
We look first at gtk/menus-appmenu.ui or gtk/menus-traditional.ui
depending on the setting of gtk_application_prefers_app_menu(). Failing
that, we fall back to the common case of gtk/menus.ui (which should
always be given). This provides a convenient way for application
authors to provide a different set of menus, depending on the desktop
environment they find themselves in.
As is the intention with other resources, if the resource base path is
unset, nothing will be loaded. Additionally, if the expected files are not
found, it is not an error -- just nothing happens.

For the transition to work the box-shadows types in the shadow list

Keep Ctrol-Shift-D as a straight toggle-the-inspector keybinding,
but make Ctrl-Shift-I always bring up the inspector, and point
it at the widget under the pointer.
When clicking 'Action' in the 'Act' dialog, we mark the third
page as needing attention a second later. This unveils that we
currently don't have any theming for needs-attention in Adwaita.
The way that GtkTextView et al pop up their context menu is to first
query to see if the clipboard has some text, and if so, enable the Paste
menu item. But since the Wayland backend hasn't had the greatest
selection and clipboard code, the callback for the clipboard got dropped
on the floor.
Add some simple code to respond to the TARGETS selection.
This makes right-clicking on a GtkTextView work fine.
Resize grips were introduced for GNOME 3.0, before we had any of the
"new GNOME app" features like invisible borders and CSD. With OS X 10.6
and 10.7, Apple has replaced the classic grips in their applications
with invisible borders as well.
New GNOME app designs don't use resize grips anymore and the new
default theme for GTK+, Adwaita, disables them entirely by forcing their
width and height to 0.
They're past their time. Remove the code to support them. This can
always be reverted if some app relies on them.
The resize grip code in GTK+ likes to call gdk_window_raise a lot. The
unfortunate side effect of gdk_window_raise is that it queues an
invalidation on the entire window, even if it's already the topmost
child.
Add a return value to gdk_window_raise_internal, and only queue the
invalidation if the raise had an effect.
Otherwise, a user that calls gdk_window_resize (window, 0, 0); over and
over won't properly fizzle out, and will queue a redraw. Clipped, but
still. These redraws can be chatty on some platforms like Wayland, and
there's no good reason to not avoid them.
This was the case for resize grips.
We decided in f8412eca34 that
we still need to react to these for a11y reasons, but left
the (then) harmless property deprecation in place. Now, the
deprecation causes runtime warnings for merely reading the

This will be %FALSE on desktop environments that do not have an

We were only setting the state transiently in ::draw, leading
to various drawing anomalies, such as labels not picking up
the appropriate color from BUTTON styles.
This is expected to happen on wayland and other platforms with no primary selection,
and just leads to the selected text being cleared after any attempt to change the
text selection itself through either mouse/keyboard.

When there area explicitly added buttons in the action area,
we were trying to ensure that the action area is visible,
but failed, since we are now hiding the action_box. Fix it
by showing the action_box when things are left in the action

We need to enclose paths containing $(BinDir) with double quotes as it
points to something like c:\foo\gtk+-x.yy.zz, which the copy command on
Windows does not like "+" in paths unless enclosed in quotes.
As the Visual Studio 2012/2013 are only slightly different from the Visual
Studio 2010 projects, we can provide support for them by using scripts to
copy the Visual Studio 2010 projects, and update the specific parts as
necessary.
Thus, there would be little maintenance overhead for these as only the 2010
projects need to be kept up-to-date as a result. This might change when we
do get the stack working with WinRT/Metro, but that's going to be another
totally different issue.
The stock icons are now built into the GTK+ DLL via resources, so don't
try to install the stock icons, and the icons don't reside in their former
positions anymore, causing messages indicating that the files cannot be
found.
This reverts commit 2e0ce67f8a.
Since g-i 1.40.0 we are using the .lib file(s) to determine the DLL(s) that
the introspection files should look for, instead of directly using the
DLL(s) directly, so it is no longer necessary to make copies of the GDK
.lib file to match the <namespace-name>-<namespace-version> convention when
we are building the introspection files for GdkWin32. Remove that from the
introspection build process as a result.
We don't set use-header-bar for message dialogs, since we
want the buttons in the action area, but we do want a nice
rounded csd titlebar. Add back the box that was used before

Give GtkAboutDialog buttons in the action area instead of hard-coding
use-header-bar to TRUE. This is for environments which don't have the
Gtk/DialogsUseHeader xsetting turned on.

We use gtk_adjustment_enable_animation to enable animated
updates of the adjustments. Currently, this is enabled
unconditionally, and with a duration that is hardcoded.
https://bugzilla.gnome.org/show_bug.cgi?id=732376
Add a private API that lets widget opt-in to animated updates of
the adjustment value. When enabled, all calls to
gtk_adjustment_set_value will smoothly transition from the old
value to the new value, using a fixed easing function and a
configurable duration. The animation is tied to the frame clock
of the widget.
By implementing this in GtkAdjustment, we can enable animation
for both scrollbars and keybindings, which are often implemented
in the child widget of the scrolled window.
https://bugzilla.gnome.org/show_bug.cgi?id=732376
This makes it possible to look up icons in resources using
the icon theme api, and should be used as a replacement
for installing icons below $pkgdatadir/icons and adding
that location to the search path.
Make icon lookup from resources work without the extra hicolor
component in the path. It is redundant, since we always treat
builtin icons as part of hicolor anyway.
Otherwise, we get every icon twice. To switch between symbolic
and non-symbolic icons, this css fragment comes in handy:
* { -gtk-icon-style: symbolic; }
Grabbing on a non-toplevel might not do what we want it to do, since it
will go on the focused widget, not the grabbed widget. Since we don't
focus the widget before clicking on it, that means that putting the
focus somewhere else and then clicking on the accelerator editor will
freeze the app. Additionally, since it's a global system grab that can't
be exited except by a key press that we won't ever get, it effectively
locks up your system as well unless you know how to break the grab or
kill the app. Ouch.
Since doing a device grab on a non-toplevel is generally considered a
bad idea, just don't do it. Use a GtkInvisible and take a grab on that
instead.
When validating the style context, we are copying the animations
from one StyleValues instance to another, and cancel the old ones.
It turns out that sometimes the old and the new StyleValues are
the same, and in this case, we end up cancelling the animations
for good.
One case where breakage from this was observed is that the spinners
in gtk3-widget-factory stop spinning when you open and close a modal
dialog on page 2. This depends a bit on the window manager; the problem
can only be seen if opening the dialog causes a transition to backdrop.
This changes the calculation of activity mode progress in the
same way as was done in GtkProgressBar a while ago, and make it
smooth, using a tick callback.
We want to stop people from using configure events
entirely. GtkDrawingArea synthesizes a configure event, but we can just
make the only user of this functionality stop it, and correct the
documentation to not mention it.
GtkCheckButton sets a different initial value for this property without
actually changing the declared default, and then relies on change notification
to update other properties (such as xalign). This, combined with glades
insistance on putting default values into ui files creates a situation
where we can't remove the redundant notification for ::draw-indicator
without causing lots of checkboxes to suddenly have centered labels.
This was seen in gnome-terminal, evolution, and other applications.
Therefore, keep the extra notification for now. This can be revisited
when we clean up the button hierarchy.
Instead of code that internally does weird things, use the FLAT style
class if has-frame is FALSE and remove it otherwise.

Since we have a paint clock, we shouldn't be sending out EXPOSE events
for OR windows inside the ALLOCATE cycle. The idea here was that we
would have to wait for a map to get an OR window to paint to, but since
then this has been abstracted away inside GDK and the paint clock.
We already update the grip position in _gtk_window_set_allocation, which
is done through the size_allocate above. Receiving a ConfigureNotify
also won't ever change a grip's visibility, so there's no point in
refreshing it.

The template documentation is lacking inlined examples on how to use the
templates API, like binding children and callbacks. This makes looking
for best practices a bit harder than it ought to be, for a feature this
useful.
These non-standard icons were dropped from Adwaita. Eventually,
the icon-browser code should be changed to show all standard
icons + whatever is actually in the icon theme, instead of
hardcoding a list of non-standard names.
If the event triggers GtkGesture::begin, and the handler ends up resetting
the gesture (say, due to taking a grab somewhere else within the handler),
still take the event as "managed", as it actually triggered recognition,
even if just to end abruptly.

Prevent a segfault in unknown circumstances, and break the ignore
deprecations wrapper out from the if statement so that we don't
cover too much ground by accident.
This reverts commit b875572f2a.
Apps like Abiword, gnumeric and gnome-chess, and toolkits like
ClutterGTK were all using this for various purposes, and this made them
break. Bring back this feature for now.
It still won't work under Wayland.
Apps had quite a bit of difficulty getting used to the new rules.
While we weren't expecting anything too deadly, it seemed that
gnumeric and Abiword both used gdk_cairo_create like this.
If a window both has an impl and its impl_window is of type offscreen,
that must mean that it is the offscreen window, and the impl window is
itself. We can reduce the indirection here and make it more clear.
This functionality is only exercised by gnome-shell, currently.
Therefore, forgetting to copy a field here means an instant
gnome-shell crash :-(. More tests needed.
Recent changes made it a breaking mistake to install symbolic icons
of the wrong size into a theme directory, or into the legacy unthemed
icon location.
Since this change affects many apps, do the extra work to keep these
icons working, but emit warnings, in the hope that this will lead to
cleaning up the mess over time.
The -gtk-icontheme() function not have any automatism for
symbolic or rtl variants built-in, instead, we expect the theme
to use selectors to provide the right icon for each situation.
The recent icon theme scaling changes make the code more
sensitive to mis-sized icons (e.g. application icons in
the app chooser). A single row whose size gets blown out
of proportion by a big icon is never wanted in a list.
We can avoid this situation by telling GtkIconHelper to
force-scale the pixbuf to the requested size.
When force_scale_pixbuf is set, the icon helper will scale the
icon to the requested size (either the pixel size, or the resolved
icon size), so we can just as well instruct the icon theme code
to do the scaling for us.
Reuse the scale information that we have from loading icons
normally, when loading a symbolic icon, so that we apply the
same size constraints.
This commit assumes that svgs have the nominal size of the
directory they are in, which will be true for all current
symbolic icons.
Previously, we were taking thresholds and min/max sizes into
account when choosing the best theme dir, but when it came
to loading the icon, we always scaled icons from scalable
directories all the way, ignoring the min/max size limits.
This commit changes things around so that we now load icons
in Threshold directories at their nominal size, and scale
icons in Scalable directories only up to the specified limits.
To override this and keep the previous behaviour of scaling
all the way to the desired size, use the GTK_ICON_THEME_FORCE_SIZE
flag.
Since the Win32 code never actually called InvalidateRgn or used the
Win32 update area at all, that meant the only thing that could possibly
invalidate the window was the Win32 window manager as part of scrolling
or resizing, which would also send it a WM_PAINT message.
But the WM_PAINT handling called BeginPaint / EndPaint, which clears the
update area completely! We also draw out-of-band, not directly when
handling WM_PAINT, so there's no way that the update area inside the
Win32 WM would match our local one.
There is no possible way that this queue_antiexpose implementation could
do anything. Remove it.
We removed the parameter from callers and from the implementation, but
not from the signature up top. I didn't notice because the branch I was
working on removed the signature entirely.
This code is only called with the current paint region as its argument.
Instead of having to copy it and do a no-op intersect against itself,
just use the current paint directly.
There's nothing better we can do for this case, now that we always
redirect drawing to a temporary pixmap. Maybe since this is already
X11-specific code, we should just do everything with Xlib directly.
cairo_surface_create_for_rectangle takes a ref on the parent surface,
so we need to drop ours.
Rename get_window_surface to ref_window_surface to make the code more
clear and to stop this error from happening again.
Previously, each begin_paint_region added to a stack of current paints,
and when end_paint was called, the paint was popped off of the stack and
the surface was composited into the parent paint surface.
However, the code was broken in the case of a backend like Wayland which
didn't keep track of nested calls and simply wiped and returned the
native impl backing surface every time.
Since this feature is flat out unused by GTK+ and we don't want to
really support tricksy things like these for other clients, just remove
the feature. If somebody does call begin_paint_region more than once,
warn and return without doing anything.
Traditionally, the way painting was done in GTK+ was with the
"expose-event" handler, where you'd use GDK methods to do drawing on
your surface. In GTK+ 2.24, we added cairo support with gdk_cairo_create,
so you could paint your graphics with cairo.
Since then, we've added client-side windows, double buffering, the paint
clock, and various other enhancements, and the modern way to do drawing
is to connect to the "draw" signal on GtkWidget, which hands you a
cairo_t. To do double-buffering, the cairo_t we hand you is actually on
a secret surface, not the actual backing store of the window, and when
the draw handler completes we blit it into the main backing store
atomically.
The code to do this is with the APIs gdk_window_begin_paint_region,
which creates the temporary surface, and gdk_window_end_paint which
blits it back into the backing store. GTK+'s implementation of the
"draw" signal uses these APIs.
We've always sort-of supported people calling gdk_cairo_create
"outside" of a begin_paint / end_paint like old times, but then you're
not getting the benefit of double-buffering, and it's harder for GDK to
optimize.
Additionally, newer backends like Mir and Wayland can't actually support
this model, since they're based on double-buffering and swapping buffers
at various points in time. If we hand you a random cairo_t, we have no
idea when is a good time to swap.
Remove support for this.
This is technically a GDK API break: a warning is added in cases where
gdk_cairo_create is called outside of a paint cycle, and the returned
surface is a dummy that won't ever be composited back onto the main
surface. Testing with complex applications like Ardour didn't produce
any warnings.
gtk_widget_set_double_buffered is now deprecated, and we don't support
non-double-buffered widgets. This means that under normal circumstances,
paints are never outside of a begin_paint / end_paint sequence, which
natively-double-buffered backends like Wayland can't possibly support.
Weston releases buffers almost immediately after they're done, which
means that GTK+ doesn't use a temporary surface and instead paints
directly onto the SHM backing store that Weston will use.
Normally, after painting to the temporary surface, GTK+ *replaces*
the existing backing surface with CAIRO_OPERATOR_SOURCE. However,
if we immediately paint to the backing surface, it might have junk
from the last paint in it. So clear out the backing surface whenever
somebody calls begin_paint_region().
Maybe we should just always use the temporary surface like the X11
codepath, since that prevents us from having to do weird things like
this, but oh well.
Add /org/gtk/libgtk/icons as a resource path, and ensure
that we always parse an index.theme file for hicolor which
makes the builtin icons available as part of the hicolor theme.
We add a new API, gtk_icon_theme_add_resource_path, which
can be used to add resource path as a base location for
icon theme content, similar to gtk_icon_theme_append_search_path.
We're going to require a complete icon theme, and we have
a test that checks for all the icons we use, so there is
no need to include all these fallback icons.
Regions are done in a very non-css way. They don't fit the DOM in that
they don't integrate into the CSS tree and they have very weird matching
behavior in selectors.
So I'm deprecating them now. GtkNotebook and GtkTreeview will continue
to use them and as long as they do, we can't remove the code for it.
But once those are ported it might be safe to remove the code as it will
clean up lots of places in the code by quite a bit.
wl_surfaces can't switch roles, so destroying the xdg_surface but not
the wl_surface means that we could get an error when trying to re-map
the surface.
We could fix this by not destroying the xdg resource and only do it at
finalization time, but it's just as easy to just create a new wl_surface.
Since the xdg roles are a special case of the surface, some compositors
like Weston destroy them automatically when the wl_surface is destroyed.
Thus, we need to destroy these first.
The Wayland compositor is completely allowed to send us configure
events for the same size, and this validly happens if we're changing
states. Fizzle these out.
The rubberband rendering code was assuming that we just have
a 1-pixel border and the rest of the rubberband is uniform.
That is not a safe assumption to make with css-styled
rubberbands, so remove it.

Paradoxically, we were loading svgs at the nominal size when
FORCE_SIZE is specified, while scaling them exactly when it
isn't.
../build/win32/vs10/gtk.vcxproj
When we switched the default for gtk-update-icon-cache to
not include image data, we should have thought about the
builtin icons. For them, we rely on image data being included.
This made the notify test fail in gnome-continuous, where we
build from git and always regenerate the builtin cache.
This pushes the initialization of is_svg to an earlier point
when the GtkIconInfo is created. This is needed because an icon
info doesn't necessarily always have a filename that we can later
extract the suffix from. For instance, builtin icons have NULL
filename.
https://bugzilla.gnome.org/show_bug.cgi?id=721895
Copy the icons in stock_icons accordingly, so that the built-in icons can
be found by GTK, as it seems that not all of them are built into
gtkbuiltincache.h.
We want to have the "-gtk-" prefix for our custom CSS properties. But
we also want to parse names starting with a "-" as style properties.
So make sure that "-gtk-" is treated like a normal property and we emit
errors when somebody uses it wrong.
This is to catch errors with people typing
-gtk-iconsource: none;
instead of the correct
-gtk-icon-source: none;
We want to make sure that the submenu action is changed back to FALSE
_after_ the menu item has been activated. This prevents the menu
teardown handler from deleting the menu item before it can be activated.
Unfortunately, GtkMenuShell emits "hide" before the item activation.
This is probably done to prevent the application from doing things like
showing dialogs when the menu is still holding the grab.
In the case where we are doing an activate, set a boolean flag on each
of the open menus (following the parent stack) indicating that we'll be
emitting another signal soon (selection done). If that flag is set, we
defer the setting of the submenu action until we receive the second
signal.

That test is not working anymore by design since commit 57c4f01e.
It was introduced pre-3.0.0 in commit 12d6b588 and the feature was never
utilized. So it seems safe to just remove the test.
When duplicating the icon_info, we forgot to set is_svg. This meant that
any application that used gtk_icon_info_load_icon_async wouldn't have
is_svg set properly.
This fixes blurry icons in the gnome-shell app picker.
TextView border windows are internal windows used to draw on the gutter
of the textview (e.g. line numbers). The test uses the gmodule hook to
programmatically draw on the border-windows at each side of the textview
and compares the result with 3x3 grid of labels.
add a reftest that checks GtkTextView text margin property comparing
with the normal margin added to the widget (they are the same when there
is nothing drawn in the gutter like line numbers etc).
Previously GtkMenuTracker tried to access "gtk_menu_tracker_item_get_is_visible",
but the correct getter is "_gtk_menu_tracker_item_is_visible". This commit
corrects this reference
https://bugzilla.gnome.org/show_bug.cgi?id=731430
Since large images are in the icon cache, and apps don't tend to use that
many icons anymore, simply don't include image data and instead make apps
load files from disk. Additionally, since they're stored in GdkPixbuf data,
that means that we have to first convert them either to a cairo_surface_t,
which requires converting pixel data to be premulitplied, or an OpenGL
texture, which requires a whole GPU upload anyway.
So, even with the icon cache, the goal of icons through zero-copy, mmap()'d
data from disk just isn't doable with the icon cache format we have. The
icon cache on my disk is nearing 100MB, since we include a bunch of
high-resolution application icons, that I doubt would be used by apps at all.
Removing this inefficient pixel data makes memory usage for all applications
go down, with no speed loss.
The icon cache also, however, has an index of what icons are in each folder,
which prevents a readdir() and allows GTK+ to know what icon is where without
having to do a bunch of stat(); calls. Keeping this data is good for GTK+,
so we should still keep the index.
It doesn't make sense to remove any code for mapping pixel data from the icon
cache. There's a plan in the works to have a symbolic icon cache that does
pixel math on 16x16 icons to prevent slow SVG rendering. 16x16 pixels are
fairly small, and such images are flat colors, which should compress easily,
so the icon cache would be worthwhile here. So let's keep the code around
in preparation for that case.
https://bugzilla.gnome.org/show_bug.cgi?id=721895
This changes makes svg icons go through the same scale calculation
code as png icons. As a consequence, an svg that is put into the
32x32 directory will actually be loaded at size 32, even if it
gets requested at a bigger size. This will let us avoid giant
spinners.

Having the same, usable, default appearance acroll platforms
trumps having a more-or-less working native theme. The default
will be Adwaita on all platforms. The native ms-windows theme
is of course still available.
Making gtk.gresource.xml generated was causing a problem for
srcdir!=builddir builds from git. Builds from tarballs are
not affected, because the tarball contains the generated file.
The former can be called individually on each sequence, and the latter will
always call the former on all currently active sequences, so only implementing
resetting on cancel() works for both cases. Also, chain up on subclasses
implementing cancel.
This fixes clicking on nautilus' file list after popping up a menu, as broken
grabs are one of those situations where sequences get cancelled individually,
the "current button" wasn't properly reset, and further clicks with button != 3
were ignored.
This used to be done before the gestures port, and was removed
accidentally, so keep the motion_notify_event handler just for
this, and fallback to having those events handled by gestures
too.
This way plain clicks can be handled in gtkmain through the usual delivery mechanism,
and get possibly handled too by widgets holding a GTK+ grab. If window dragging is to
be started, the sequence will be claimed (and a grab will happen afterwards), notifying
properly the grabbing widget that event delivery was interrupted.
This makes it possible to dismiss popovers by clicking on window headerbars, while
still making it possible to drag the window with the popover opened.
Weston numbers its touch sequences ids starting from 0, thus simply
setting the GtkEvents touch.sequence to the touch id value typically
causes gdk_event_get_event_sequence to return NULL. Unfortunately this
confuses other parts of GDK.
As both weston & mutter keep the sequence id between 0..max_dev_touches
-1 simply use + 1 to keep the id > 0. While this isn't entirely correct
(compositor could send -1 as the touch id), this keeps the touch id in
gtk tied to the touch id from weston which is useful for debugging. A
more thorough solution could be done when it turns out this is an issue
in practise
https://bugzilla.gnome.org/show_bug.cgi?id=731371
The non-zero default default-border was causing buttons to shrink as
the focus moves around them. Themes which want a default-border should
define it explicitly.
The code is actually prepared for that, the gesture was initially limited
to only handling GDK_BUTTON_PRIMARY because it only used to handle row
activation.
This gesture acts only on events from the bin window, and checks that
either the pressed row is draggable, or the conditions for rubberband
selection apply.
A multipress gesture takes care of autosizing on double click, and
a drag gesture is used for both column dragging/resizing (only one
can happen at a time).
When placing tooltips, the csd shadow will get 'pushed up' and
may end up underneath the pointer. We don't want this to cause
the tooltip to be hidden, because that leads to flickering, so
ignore the shadow when finding the widget under the pointer.
For csd override-redirect windows, we don't set up resize handles,
but we were not ignoring the margin in all places, causing some
size calculations to go wrong.
... from per style data to only existing once per style context. This is
technically an API break because it no longer allows getting different
style properties between save()/restore() pairs, but I don't think this
was ever intended to work that way, as the style property API was to be
used and is used via gtk_widget_get_style().
And it simplifies code a lot.
We used to accept the same syntax for text-shadow and icon-shadow as
we accept for box-shadow. However, box-shadow does accept a spread and
the inset keyword while the others should not.
The signal needs to be emitted after the text insertion as at-spi gets
the text to compute the inserted text due to the AtkText::insert-text
signal not containing it.
Also adjust position to reflect changes to the offsets.

This is old code from dating back many years. Nowadays, we can
just use css drawing and csd windows to achieve much the same
effect.
Themes will need some adjustment for this change.
https://bugzilla.gnome.org/show_bug.cgi?id=731187
This commit makes it possible to use client-side decorations for
override-redirect windows by calling _gtk_window_request_csd()
before realizing the window. Since the wm won't do interactive
resizing for us in this case anyway, don't bother creating
the border windows we use for this purpose on regular toplevels.
To make this accessible to themes, we set a "csd" style class
on client-side decorated windows. With this, .window-frame.csd.menu
can be used to define the shadow for csd menus, and .menu can be
used to define a border for menus under non-composited wms.

This tests just a few basic things for now. Mainly, that we don't
emit redundant notifications for enum, flags, int and boolean
properties. It also checks that we do emit the expected notifications
when the value actually changes. This is checked for string, double
and float properties as well.
There is a large number of exceptions in the test, and a lot more
checks that could be done. One class of exceptions is all the places
where we have -set booleans to go along with another property. We
should have a dedicated test for these pairs. Another class of
exceptions is where naked objects created by g_object_new () just
don't have the full functionality - e.g. a tree selection without
a tree view does not work very well. We set up the instance object
better for these situations.
A few properties here are special, and can't benefit from it:
those which are just shorthands, like ::margin and ::expand,
and those that have explicit -set properties, like::hexpand
and ::vexpand.
This one is a little tricky, since we override this property
in many places, and you cannot add flags when overriding. So,
all places where this is overridden will have to make sure to
notify explicitly.
When we expanded the GtkLicense enumeration in 3.12, we forgot
to update the limit check in gtk_about_dialog_set_license_type.
Caught by testing property notification for enum properties.
The reftest is testing "transparent" works as expected by drawing a
purple background once with purple and once with transparent and
expecting the same result. This works fine unless anti-aliasing happens
at rounded corners. The overdraw of the 2nd background changes the
antialiased pixels.
Fix this by explicitly setting the border radius to 0.
Also reindent the file to make it more readable.
The a11y headers are now listed with the main Makefile.am of GTK, and
GDK introduced deprecated headers, so we need to account for them for the
build of the introspection files.
Currently, due to the way that Visual Studio 2010+ projects are handled,
the "install" project does not re-build upon changes to the sources, as it
does not believe that its dependencies have changed, although the changed
sources are automatically recompiled. This means that if a part or more
of the solution does not build, or if the sources need some other fixes
or enhancements, the up-to-date build is not copied automatically, which
can be misleading.
Improve on the situation by forcing the "install" project to trigger its
rebuild, so that the updated binaries can be copied. This does trigger an
MSBuild warning, but having that warning is way better than not having an
up-to-date build, especially during testing and development.
Otherwise, it is pretty hard to keep track of what
classes are missing from the list. As a consequence,
several of the existing classes were missing. Add those
at the same time.
We were applying response based heuristics, even if the button
is explicitly put in the headerbar. That broke button placement
in some epiphany dialogs, such as the Cookies one. Therefore,
restrict the heuristics to action widgets that are added through
gtk_widget_add_action_widget() or <child type="action">, where it
is not possible to specify placement explicitly.
There are plans to add session-dependent defaults to GSettings
(based on the newly standardized XDG_CURRENT_DESKTOP); until
then, the WM uses a different schema for its button-layout
setting in classic mode. So for the time being, do the same
and pick the alternative schema when XDG_CURRENT_DESKTOP
indicates that we are in a classic session.
(It's not pretty, but hopefully won't be with us for too long ...)
https://bugzilla.gnome.org/show_bug.cgi?id=731273
Pick up the setting from the org.gnome.desktop.wm.preferences schema
if available. It is slightly more involved than other settings, as
the actual button names used in the schema differ from the ones we
use, so we need an additional translation step.
https://bugzilla.gnome.org/show_bug.cgi?id=731273
When combining action child type with <action-widgets> to assign
response ids, we were not properly updating buttons that ended up
getting added to the headerbar before they have a response id.
Fix this by reapplying the headerbar button setup after parsing
<action-widgets>, and make sure to also update the suggested-action
style class.
If called when already popped down, warnings would be issued due
to priv->grab_pointer being unexpectedly NULL, this would happen
in regular operation when selecting items in appears-as-list mode.
So both add a NULL check for priv->grab_pointer, and bail out early
if the popup window is already hidden.
GtkKineticScrolling implements the actual physics laws for friction
and springs. When created, position/velocity/boundaries/constants are

A multipress gesture takes care of link handling, and char/word/all
selection mode on selectable labels. A drag gesture is used for both
text selection and DnD checks on selectable labels.
A multipress gesture takes care of clicks, and where those happened.
If the click is meant to move the slider while pressed, the drag gesture
takes over, dragging the slider while active.
Widgets becoming insensitive won't receive further events, but there
could be chances the controllers don't get properly notified and reset
in those situations.
The signal handler for the visibility of menu items changing had the
wrong signature, resulting in the GParamSpec from the notify signal
being treated as a boolean (which was always true). This resulted in
items being added over and over and never being removed.
Fix that...
Since commit 872fbfac the GtkWindowGroup was split out from the GtkWindow
sources, so include gtkwindowgroup.h to avoid C4013 warnings/errors
(implicit declaration of ...) on gtk_window_group_add_window().
We were setting the next-tab properly, but were trying to
read it off the wrong object. Now, going from a cell renderer
attribute mapping to the model, or from an action-name to the
action actually works.
The touch_event handler was missing those when emulating pointer events
for the widgets that get GDK_TOUCH_MASK set, but have no specialized
touch handlers.
This code is a product of early stages in the gestures branch, where
capturing would have an effect outside grab boundaries. But this isn't
really the case, so every gesture outside the grab scope must be reset
to avoid keeping stale data.
This tests both a sequence being claimed early to be then denied
(and handled deeper in propagation chain), and a sequence being
claimed late in the capture phase (and thus being cancelled deeper
in the propagation chain)
Before this change, a sequence being claimed deep in the event propagation
chain would make the sequence go denied on every ancestor, regardless of
previous state.
To make things more consistent, only deny the sequence if it was previously
claimed, so the behavior is the same for gesture groups within the widget
than for those outside the widget.
The gestures testsuite has been updated to reflect this new behavior.
It might happen that a gesture claims a sequence before any other gesture
in its group even handled a single event from that sequence. In that case,
ensure the state is set accordingly right when the sequence is handled in
those.
The "group" gesture testcase has been updated to observe this behavior.
The CSS editor was feeling a little sluggish, because it was
reparsing and reapplying the CSS on every keystroke. Add a small
delay, to make this feel smoother.
Like the GDK and GTK portions, use autotools scripts to generate the
complete projects for gtk-inspector as sources there seem to change from
time to time.
It might be so that this, like the a11y sources, will be referenced from
the main Makefile.am of GTK directly, but just do this so that the
projects can build properly.
This test check that resizing the window when expanding
the expander yields the same end result as having the
expander expanded to begin with. The test uses the inhibit
mechanism introduced in the previous commit.
This adds an inhibit api that code from the reftest module
can use to delay the taking of the snapshot. Also refactor
the code in gtk-reftest to use the inhibit mechanism for
its own delaying of the snapshot until after the first
expose.
Every button press/release event reaching the the multipress gesture in GtkWindow
and happening in the "title" region must be handled, regardless of the event widget.
Children there wanting the event(s) for themselves are (and were always) expected
to stop event propagation.
So the only place to check for the event widget's "window-dragging" style property
is the "content" region, which matches the pre-gestures behavior.
This fixes some issues with sequences being mistakenly claimed (and events not
propagated further) on situations it shouldn't.
The multipress gesture must react to either direct events on the
GtkWindow (special cased through _gtk_widget_check_handle_wm_event),
or bubbled events from child widgets. Ensure bubbled events go
through the gesture, those are fed manually to make sure events are
only handled once, in either one or other place. The implicit grab
will ensure that doesn't change mid-action.
Otherwise the event is possibly handled, but still propagated further anyway.
Ensure the event is consumed by claiming the current sequence on the
GtkGestureMultiPress::pressed handler.
::row-activated only used to be triggered by GDK_BUTTON_PRIMARY, so make
the multipress gesture handling this now to be only triggered by that same
button.
https://bugzilla.gnome.org/show_bug.cgi?id=731020
This gesture was only meant to react on GDK_BUTTON_PRIMARY (either
through real pointer events, or implicitly assumed from touch events),
as it used to behave before gestures. Otherwise the gtk_drag_begin*()
call assumes being triggered by button 1, and the drag misbehaves
because that button isn't really in the state mask.
https://bugzilla.gnome.org/show_bug.cgi?id=731016
When going from attribute mapping to model, it makes most sense
to go directly to the data tab, and when going from an action
name to the owner, we want to show the actions tab. Make it so.
This reftest makes use of the new feature to add signal handlers.
It adds a libreftest.so module containing all the code for the reftests.
When adding a test named reftest.ui, please keep code contained in a
source file names reftest.c and add that file to Makefile.am.
https://bugzilla.gnome.org/show_bug.cgi?id=730833
When connecting signal names, gtk-reftest now allows you to use a colon
in the signal handler name like so:
module:function_name
where module is a module loaded from the same directory (or the .libs
subdirectory for compatibility with uninstalled libtool) as the running
test and the function is resolved in that module. Of course, normal
function names work as before.
The extra condition here that caused the current child to
not redraw during reordering was introduced in f383e1f1
during the port to ::draw, but was not explained in the
commit message, and removing it has no obvious negative
effect.
https://bugzilla.gnome.org/show_bug.cgi?id=730767
Just calling get_type() does not ensure that the signals, properties
and everything else gets set up properly. Ensure it is, by calling
g_type_class_ref() before using the type. This fixes the testcase
added in the previous commit.
Those might trigger the destruction of some widget that would dispose the
event controller while the event is still being handled, so keep an extra
ref on the controller during event processing.
Without this information introspection-based consumers don't realize
they can include context information, but instead think that they
receive an extra gpointer argument (which they don't know how to
handle).

This will hopefully help resolve the circular dependency between
libgtk linking against inspector/libgtkinspector and inspector/
needing extract-strings from gtk/.
I didn't preserve the EXEEXT decorations in this operation -
automake gave me stern warnings about it, so I just dropped them
all. Somebody who cross-builds GTK+ will have to reconstruct this.
This prevents some of our generic object implementation tests
from working with gesture objects. Instead, add g_return_if_fail
checks in all the gesture constructors.
Mainly doing s/TARGET/BUBBLE/ on the fully ported widgets, but GtkTreeView
where the double click handler has moved to GTK_PHASE_TARGET so it runs
parallelly to the still existing event handlers.
Previously, there would be globally just a capture and a bubble phase,
with the event just going down the hierarchy once, and the up once.
GTK_PHASE_TARGET actually meaning "run within event handlers", so in
a hierarchy of 3 widgets, emission would be:
Capture(C)
Capture(B)
Capture(A)
Target(A) (if event handlers allow)
Bubble(A)
Target(B) (if event handlers allow)
Bubble(B)
Target(C) (if event handlers allow)
Bubble(C)
This commit changes this behavior and uses GTK_PHASE_TARGET in a less
misleading way, running only on the widget that was meant to receive
the event. And GTK_PHASE_BUBBLE has taken over the execution place of
GTK_PHASE_TARGET, so the emission remains:
Capture(C)
Capture(B)
Capture(A)
Target(A)
Bubble(A) (if event handlers allow)
Bubble(B) (...)
Bubble(C) (...)
As it was, GTK_PHASE_BUBBLE was useful for running event controllers
paralelly to event handlers, without modifying a single line in those.
For those mixed scenarios, Any of the other phases will have to be
used at discretion, or the event handlers eventually changed to chain
up and let the default event handlers in GtkWidget to be run.
The events to those are fed outside the regular event propagation scheme,
through _gtk_window_check_handle_wm_event(), so set the controller to
GTK_PHASE_NONE so events aren't processed first manually, and then
automatically.
Event controllers now auto-attach, and the GtkCapturePhase only determines
when are events dispatched, but all controllers are managed by the widget wrt
grabs.
All callers have been updated.
Go back to respecting GtkMisc::xpad/ypad. Not doing so breaks
the misc-alignment reftest. As long as we still derive from
GtkMisc, we may as well do this.
The icontheme lookup code has a special-case that prefers builtin icons
if the theme name is "hicolor". This is problematic for our reftests,
which run in a barebones environment with not settings.
Drop the ref on the action muxer in finalize, and also make sure
shutdown() tears down the muxer setup done in startup().
When GtkApplication adds itself to a muxer, it causes the muxer to take
a ref on the GtkApplication. This has to be undone in shutdown() to make
sure the GtkApplication doesn't end up holding a ref on itself.
https://bugzilla.gnome.org/show_bug.cgi?id=730383
And handle the fact that drawing bounds are now handled by this API and
the corresponding gtk_widget_get_clip().
Also add _gtk_widget_supports_clip() function to check if a widget has
been ported to the new world.
Now that labels and images no longer use x/yalign in their code,
we need to make gtk_misc_set_alignment set the h/valign for these
widgets, to keep it stumbling along until its final demise.
https://bugzilla.gnome.org/show_bug.cgi?id=730613
Those get in the middle more than help on these widgets, the widget
is already packed with clickable areas and having handles (and their
invisible clickable area around) hovering above don't help, plus the
purpose in most likely numeric values is a bit doubtful.
All touch events are either consumed by the up/down panels, or
the swipe gesture, all GtkEntry handling of touch events on the text
window is avoided, so handles to not appear anymore.
the "bubble" phase used to run before event handlers before GTK_PHASE_TARGET
was added, in order to keep phases in the expected order, move GTK_PHASE_BUBBLE
to be run (still invariably) after event handlers.
The only behavioral change should be wrt widgets wanting mixed event handler/
gesture handling, they could previously attach the gesture to the bubble phase
and check for gtk_gesture_is_active() in the event handler to bail out, they'll
have to use GTK_PHASE_CAPTURE for that purpose from now on.
The handle is still centered horizontally, but the extra vertical
space wasn't taken into account, leading to misplacing the dragging
point (and the handle) during motion events.
GtkPaned may just capture pointer events because the child widget
doesn't happen to have GDK_TOUCH_MASK set, resort to checking the
device in that case.
Dragging is all handled by a GtkGesturePan now, matching the
paned orientation.
On touch events, a wider area is listened for, so touch events
don't need to be as accurate to initiate dragging, if no dragging
is truly initiated in this case, events are just forwarded for
child widgets to handle.
A pan gesture is used to handle switch dragging, which is only triggered
by horizontal panning movements. A multipress gesture handles the cases
where clicking without dragging happens, just toggling the switch.
A pan gesture is optionally attached if there is only one scrolling direction, the pan
gesture orientation is changed so movements tangential to the scroll direction get
scrolling cancelled (The pan gesture is automatically denied when that happens, and
that state change spreads to the others gestures in the group). If the pan direction
happens in the expected directions, no cancellation happens, and scrolling eventually
takes place.
Multiple calls are supposedly allowed to change the phase (although
unlikely to happen), so remove the g_return_if_fail() checking whether
the controller was already added.
Presses alternatively show and dismiss the popover, the popover is still
always shown invariably after any dragging happens (either text selection,
or dragging a text handle)
Presses alternatively show and dismiss the popover, the popover is still
always shown invariably after any dragging happens (either text selection,
or dragging a text handle)
Similarly to GtkTextView, a GtkGestureMultiPress gesture handles
button/touch presses to initiate one selection mode or other, and
a GtkGestureDrag is used to handle text selection and DnD checks.
The code from button press/release, motion, and grab_notify handlers
has been shuffled into the actions triggered by those gestures.
A GtkGestureDrag is used for color selection, removing also the
need to track the pointer state in widget data. The GDK grab performed
just to set the crosshair cursor has been replaced by a call
to gdk_window_set_device_cursor(), which will be unset if the
drag operation is finished, or cancelled due to the implicit grab
being broken.
When the pointer cursor is updated on CSW, lookup for either a device
cursor, or a global one. It would previously lookup for windows with
a global cursor, and then check if it had a device cursor, which would
skip windows with only device cursors set, and unexpectedly set the
global cursor.
All "exclusive" gestures listen for either pointer events, or
"pointer emulating" touch events, so only a single sequence at
a time can make these run.
This signal will always be paired with a ::pressed signal, unless
the sequence is cancelled, or the controller is reset. the n_press
argument in the signal always matches the ::press signal one, even
if GtkGestureMultiPress::stopped was emitted in between.
The current sequence (as per gtk_gesture_single_get_current_sequence)
is used to find out the coordinates. And only emit ::pressed if the
gesture began through a GDK_BUTTON_PRESS/TOUCH_BEGIN (eg. not due to
an extra touch being lifted)
Just call the controllers on that phase if the default widget handlers
are run.
For compatibility reasons, in the touch event handler, let the pointer
emulating touch be transformed to a pointer event as usual, in order to
have widget handlers a chance to run at all. If they have to be managed
by a controller in that phase, it'll have to be through the default pointer
event handlers.
This phase is meant to run in the default widget handlers, as opposed
to externally as in the bubble/capture phase. This will be most usually
the expected phase for every controller replacing code in event handlers
in GTK+, just so invocation and triggering order is kept unaltered.
That may happen separately from grab-notify, and also due to external
reasons, so ensure all sequences are cancelled if a grab is taken
in some GdkWindows that would obscure events on the controller.
We can end up with _gtk_widget_remove_controller getting called
while we are iterating over the list in _gtk_widget_run_controllers.
To avoid trouble, only mark the event controller as dead by
setting data->controller to NULL, and defer the actual freeing
and list manipulation to the loop in _gtk_widget_run_controllers.
Update other places that operate on controllers to handle
data->controller being NULL.
Make it really sure that the event is only emitted after every gesture
that consumed the button press is done with the sequence.
The event must only be emulated if a gesture in the capture phase happened
to consume the event, be cancelled, and
Sequences may be cancelled within the ::sequence-state-changed handler, which
would change the points hashtable as it's being iterated in this function. So
iterate over a list of sequences and let the hashtable change freely.
The propagation phase property/methods in GtkEventController are gone,
This is now set directly on the GtkWidget add/remove controller API,
which has been made private.
The only public bit now are the new functions gtk_gesture_attach() and
gtk_gesture_detach() that will use the private API underneath.
All callers have been updated.
Within a widget, if a gesture accepts a sequence, it would previously
cancel every other gesture that not in the same group. Change this to
only cancelling gestures that previously claimed the gesture, and let
gestures with state=NONE for that sequence remain like that.
This enables late recognition of gestures, even on the presence of
another gesture group that was more eager at claiming the gesture.
One usecase is user-defined panning gestures on scrolledwindows,
if ::capture-button-press is TRUE (eg. the default), the gesture is
claimed early in order to consume the button press, but that would
tipically make every other gesture group deny the sequence. With
this change, the pan gesture can keep state=NONE, and later claim
the sequence for itself if the panning gesture is recognized.
Also, do not propagate state=DENIED to every gesture in the widget,
that was unintended.
If no match is found with the gesture widget when poking the event
window parents, bail out safely instead of falling in an infinite
loop. This was seen on Mutter.
The utility of those signals is somewhat dubious now that there is
gtk_gesture_group(), so make that the only way to coordinate gestures.
The cooperation model offered by gtk_gesture_group() is flexible
enough,
Listen for notify::sequence-state-changed on the controller, so the
only way to manipulate a sequence state are gtk_gesture_set_sequence_state()
and gtk_gesture_set_state().
Also, make use of gesture groups, so the sequence state is set at once
on all gestures pertaining to a single group. Within a widget, if a sequence
is claimed on one group, it is made to be denied on every other group.
This API eliminates the need for overriding
GtkWidget::sequence-state-changed virtually everywhere. Grouped
gestures share common states for a same GdkEventSequence, so the
state of sequences stay in sync across those.
A multipress gesture is used to control all this, replacing
single/double click custom code, and triggering window dragging
when the multipress is stopped, yet active (ie. the sequence remains
pressed).
This gesture is used by gtk_drag_source_set() to determine
whether dragging moved past the threshold. The gesture events
are handled via the usual ::event callbacks, so we don't mess
up with callers expecting that to happen in a signal handler.
If the sequence gets claimed somewhere else in the event widget
stack, the DnD gesture will be cancelled.
With gtk_gesture_get_point() returning events in
gtk_event_controller_get_widget() coordinates, we no longer need
to compensate for the overshoot here.
GtkEventController may be certainly useful to keep event
handling self-contained in other places than gestures, but
the current widget API is highly related to gestures, so
just using GtkGesture as the argument there will be quite
more convenient. The other places where GtkEventController
make sense as a base object will better provide their own
hooks.
Gestures attached with this phase will expect callers to have it
receive events through gtk_event_controller_handle_event(), but
the gesture will still be notified of sequence state changes,
grabs, etc...
Translate events meant for other widgets/windows, so gtk_gesture_get_point()
always returns coordinates based on the gtk_event_controller_get_widget()
allocation.
If a gesture has denied sequences (so those are presumably handled above/below
the widget), it shouldn't attempt to handle extra touches, even if those end
up matching the expected number of touches.
Gestures should always receive one of such events in order to be activated,
and the propagation mechanism will ensure they do so if the original event
was caught up the widget hierarchy by another gesture that is now declining
the sequence.
If the captured touch begin or button press event have been consumed
for the given sequence, propagate it upwards if the sequence goes from
claimed to denied, so the widgets on the way to the event widget receive
a coherent event stream now that they're going to receive events.
The policy of sequence states has been made tighter on GtkGesture,
so gestures can never return to a "none" state, nor get out of a
"denied" state, a "claimed" sequence can go "denied" though.
The helper API at the widget level will first emit
GtkWidget::sequence-state-changed on the called widget, and then
notify through the same signal to every other widget in the captured
event chain. So the effect of that signal is twofold, on one hand
it lets the original widget set the state on its attached controllers,
and on the other hand it lets the other widgets freely adapt to the
sequence state changing elsewhere in the event widget chain.
By default, that signal updates every controller on the first usecase,
and propagates the default gesture policy to every other widget in the
chain on the second. This means that, by default:
1) Sequences start out on the "none" state, and get propagated through
all the event widget chain.
2) If a widget in the chain denies the sequence, all other widgets are
unaffected.
3) If a widget in the chain claims the sequence, then:
3.1) Every widget below the claiming widget (ie. towards the event widget)
will get the sequence cancelled.
3.2) Every widget above the claiming widget that had the sequence as "none"
will remain as such, if it was claimed it will go denied, but that should
rarely happen.
This behavior can be tweaked through the GtkWidget::sequence-state-changed and
GtkGesture::event-handled vmethods, although this should be very rarely done.
The kinetic scrolling feature is now implemented using a
GtkGestureDrag and a GtkGestureSwipe, plus a GtkGestureLongPress
in order to denying the sequence, so it is possibly handled
underneath.
A controller can be optionally hooked on the capture or the bubble
phase, so the controller will automatically receive and handle events
as they arrive without further interaction.
Now, all captured events run from the toplevel to the deepmost widget,
regardless of GTK+ grabs. This makes captured events more useful to
event controllers if used together in the hierarchy with widgets doing
old fashioned event handling and GTK+ grabs.
This gesture handles any number of clicks, ensuring multiple presses
stay within thresholds and timeouts. When anything of that happens,
the gesture is reset and press count starts from 1 again.
Optionally, the gesture can be given a rectangle, used in in presses > 1
to ensure the consecutive presses happen on user imposed areas.
This gesture implementation recognices swipes on any direction.
The "swipe" signal has the X/Y velocity vector components, so
those can be used for direction guessing and velocity thresholds.
This test just checks that all the icon names that GTK uses are present
in the default icon theme.
As icon names are not checked programmatically and we do not want to run
into missing-icon icons in the code, this test seems necessary.
For now, it's just a stub that tests stock icons.
The change to take out unneeded NULL checks requires some care
at startup: we check both adjustments when any of them changes;
we need to do those checks in the same order in which we create
the scrollbars, otherwise we'll try to get the adjustment of
the vscrollbar when we just set the up the hscrollbars' adjustment.
When the color editor is visible, there is no way for the
application to know about the changes that are happening.
Fix this by emitting property notification for the "rgba"
property.

This avoids a bunch of policy problems with deciding how to lay
out the window menu under different WMs.
For now, we use the special event _GTK_SHOW_WINDOW_MENU, but we
hope to have this standardized in wm-spec quite soon, as KDE wants
it as well.
To make the icontheme test run successfully when installed,
we need to use the correct test-framework-provided location,
and we need to install the test theme without stripping its
subdirectory structure.
We see an active link when creating the menu, but by the time
the menuitem is activated, we've received a leave notify that
makes the label clear its active link. Instead, give the
menuitems a direct reference to the link that is active when
the menu is created.
Problem pointed out by Tim Baedert
We know the objects in a size group are always widgets, so we
can avoid hard-to-track down problems with weak references by
just cleaning up when the object gets destroyed. There is still
a chance that we show a widget as part of the group after it
has been removed, but size groups simply have no signals that
would let us avoid that.
Add a tab that shows size groups of a widget. The properties
of the size group are available here, as well as the widgets
that are part of the size group. We highlight the widgets in
the application when their row in the inspector is hovered.
In contrast to the flashing, where we blink the widget a
few times, this is explicitly turned on and off.
It will be used for indicating widgets that are part of
a size group, in the next commit.
The focus widget might be unset, just to be set again on a widget inside
the popover. Have the popover wait till the focus is actually moved outside
before dismissing.
Move away from cell editing, and use a popover instead. This makes
it easier to e.g. use a color chooser - there's just not enough room
in a cell for many things.
Much of this code is adapted from tests/prop-editor.c.
The child properties in GtkAssistant are somewhat broken, since
they are not on direct children - but that is no reason to crash
if somebody does ask for child properties of direct children.
When a model is sortable, but the the column is not currently used
for sorting, we want to reserve the space for showing the sort
indicator. But we currently set the icon to 'missing-image', which
is not great to show all over the place. So, just set the opacity
to 0.
With the keybinding, it is possible that users may trigger the
inspector unintentionally. Show a dialog that informs them about
whats going on and gives them a chance to back out.
The warning dialog can be bypassed with the
org.gtk.Settings.Debug inspector-warning setting.
All the globals we care about should appear before doing anything
else, up-front, so a single round-trip after adding the registry
should be more than enough.
Update visual.c to use Windows themes rather than the stock Raleigh theme,
and avoid hardcoding data paths for Windows (and Mac). As the dlfcn.h
functions are only used when Python is enabled, move its inclusion there[*].
Also ensure that variables are declared on the top of the block.
[*] Python support Windows needs to be investigated, as POSIX signal
handling is used there.

Add project files to build the GtkInspector sources, as gtk-inspector is a
required portion for GTK+. "Install" the
org.gtk.Settings.Debug.gschema.xml gsettings schema file as well, so that
people can trigger GtkInspector as they develop and test their GTK+-based
programs.
Since you can't take grabs on unmapped windows, GtkMenu takes a grab on
the menu in a convoluted way: it first grabs another window, shows the
menu window, and then transfers the grab over to the GtkMenu widget.
For normal menubars, this is perfectly fine, as the first window it grabs
is our toplevel, and that gets picked up in our transient path. For
GtkMenuButton or other spurious uses of gtk_menu_popup, it creates a new
temporary input-only window which it takes the grab on, known as the "grab
transfer window". Since this window isn't a transient-for of our new menu
widget window, the grab isn't noticed when we go to show it, and thus the
menu ends up as a new toplevel.
Add a special hack to GtkMenu and the Wayland backend which lets us notice
this "grab transfer window", and include it in our grab finding path.
It's sort of terrible to have to hack up the widgets instead of just the
backend, but the alternative would be an entirely new window type which is
managed correctly by GDK. I don't want to write that.
The entire UI is constructed with templates, so the wrapper
constructors are never called, except for gtk_inspector_window_new,
which gets called from the GTK+ code.
Show the actions that are added to GtkApplication and
GtkApplicationWindows, as well as action groups that are
inserted elsewhere with gtk_widget_insert_action_group.

Moving the inspector into libgtk lets use reuse internals without

Add two new icon lookup flags, GTK_ICON_LOOKUP_DIR_LTR and _RTL,
which tell GtkIconTheme to look for icon variants which have a
-ltr or -rtl suffix. GtkIconHelper adds these lookup flags when
looking up icons.
Note that due to the way this overlaps with symbolic icon lookup,
directional variants of symbolic icons must be called -symbolic-rtl, not
-rtl-symbolic.

Provide API to query the matrix instead of API that applies the matrix
directly. This makes the API more flexible.
See the commits implementing shadows.
This test is a bit brittle because it doesn't properly rely on CSS
properties but needs to use widget style properties to turn of extra
sizing from widgets.
It might break in the future when porting widgets to draw properly.
When forcing regular or symbolic icons, fall back to the default
specified icons. This ensures that when no symbolic icon is present, an
icon will still appear - the regular one.
GTK_ICON_LOOKUP_FORCE_REGULAR and GTK_ICON_LOOKUP_FORCE_SYMBOLIC can be
used to force a regular or symbolic icon to be loaded, even if the icon
names specify a different version.
This is intended to support the CSS property -gtk-icon-style.
The values can be:
"requested" - the style as requested
"regular" - use a regular full-color icon
"symbolic" - use a symbolic icon
The property defaults to "requested", so no changes should be seen
unless CSS overrides it.
It is also inherited, so that using this CSS
.toolbar { -gtk-icon-style: symbolic; }
is enough to force the whole toolbar to use symbolic icons.
The value implements the 2D parts of CSS transforms. See
http://www.w3.org/TR/css3-transforms/
For the specification.
All it does is give us an expressive way to define Cairo matrices (and
their transforms)
This allows using icons from the icontheme as images in CSS. The
reasoning is that this allows to give the image control about how it's
scaled (by using the icon theme's scaling method. So we can get crisp
images at different resolutions.
Replace them by GtkWidget h/valign. The only remaining uses
are those where a size group is involved; they can't be replaced
until GtkLabel stops looking at GtkMisc alignment for size
allocation.
Wayland's mechanism tells us all of our new states, rather than
telling us which ones were added and removed. Add a new private
interface so that we can simply specify the new states as a
bitfield directly rather than having to compute which ones were
added and removed.
Make the relative_to widget the parent for a GtkPopover's
GtkActionGroup. This, for example, makes the menu model of a
GtkMenuButton find action groups attached to the button.

Instead of manually doing it everywhere, just call set_object (NULL)
from the selection_changed handler. Fix all the set_object() functions
to deal with NULL.
Nice to have a quick way of testing this everywhere.
The implementation is not quite perfect: due to the way text
direction works in GTK+, widgets that appear in the inspector
window while we are flipped will inherit the flipped direction
instead of the fixed direction of the inspector window.
The widget-tree was not safe against object just going away.
Fix this by using row references instead of iters where
necessary, and by using weak refs to clean up when objects
die.
It does not really add much over the sensitive/insensitive rendering
that is already indicating which widget is mapped. At the same time,
set up signal handlers so we can update that when the widget changes.
Not only was the property list connecting to notify::bla for
each property individually, it was also leaking the signal
handlers when the selected object changed. Fix both.
When showing the objects in the tree, use the property name
as the name thats shown in the list. This makes it easier
to differentiate e.g. hadjustment and vadjustment in a
GtkScrolledWindow.
Add a tab that shows available signals for each object. For now,
we only show if each signal has handlers connected or now. More
functionality will be added later.
The list of toplevels also includes hidden combobox popups
and the like, so we have to be a little careful. To ensure
the right choice, we now pick the first visible window
that is not a GtkInspectorWindow.
Instead, we want to let GTK+ open a window whose life-cycle
it can control. We just ensure that all our types are registered
when the module is loaded, so GTK+ can find them.
The positioning of the highlight window was not reliable; instead
just use a after-handler for the draw signal, in the same way that
drag highlights are drawn by GTK+ itself.
And copy the code for grabbing a widget via pointer from testgtk;
that code is known to work.
Quoting the spec:
If the cascaded value of a property is the unset keyword,
then if it is an inherited property, this is treated as
inherit, and if it is not, this is treated as initial.
Spec in question:
http://dev.w3.org/csswg/css-cascade/
Also use unset in the reset-to-defaults.css we use to reset css in
reftests.
In the GTK_IMAGE_ICON_NAME case, instead of keeping around the icon_name,
create a GThemedIcon and use that. This way, we can reuse the code paths
for the GTK_IMAGE_GICON case.
We have to use the internal accessor to the visible flag, instead of
calling gtk_widget_set_visible(), from within the show() and hide()
implementations - otherwise we'll recurse.

This small refactor makes the code more readable when adding more
transition types that have left, right, up, and down variations.
It adds inline boolean functions to tell information about transition
types (avoiding long if clauses) and changes long chains of "else if

to get longer as more transition types are added.

PropertyInfo: Use a GParamSpec instead of a char * for the property name.
SignalInfo: Use signal id and detail quark instead of a detailed signal name string.
This not only save us a few malloc in each case but lets us simplify the code

...unless they are labeled.
To implement this, keep track of the nesting depth of section boxes,
starting from 0 for the toplevel and the submenu ones, and only
insert unlabeled separators if the depth is at most 1.
When the adjustment changes (due to e.g. a mouse wheel scroll) we update
the prelight. The part that un-prelights the previous prelight was
broken by the the pixel cache, as it called update_prelight in the
middle of the scrolling operation, where the windows were moved
but the tree_view->priv->dy was not changed to the new value. This
caused the updates to the pixel cache to go to the wrong place.
We fix this by fully doing the scroll before we update_prelight().

GtkMenuTrackerItem::visible was removed a few commits ago.
It is not necessary to bind visible anyway, since the menu
tracker will insert and remove items as their visibility

Rendering doesn't do much about clipping drawing operations to the window shape,

When activating an item using mnemonics GtkRecentChooserMenu does not select a

Fixes Bug 495105 "Open recent file keyboard shortcuts do not work correctly"
The real reason for the problem that the just reverted change

Instead of using GtkMenuTracker to flatten the sections into a single
linear menu, handle the sections ourselves by nesting boxes.
Each section gets an inner and outer box. The inner box numbers its
children in the way that the tracker instructs. The outer box
containes the inner box and the separator, if appropriate.
Having the two separate boxes will allow us to change the orientation of
the inner box if we want to pack widgets horizontally within a section.
Add the possibility of a GtkMenuTracker that performs no section
merging. Instead, it will report an item in the form of a separator for
subsections. It is then possible to get a separate tracker for the
subsection contents by using gtk_menu_tracker_new_for_item_link().
We have some API in GtkMenuTracker and GtkMenuTrackerItem that is
specifically designed to deal with submenus.
Generalise these APIs to take a 'link_name' parameter that we always
give as G_MENU_SUBMENU for now. In the future, this will allow creating
trackers for other types of links, such as sections.
Make this a property just like all of the other things and make the APIs
for accessing it non-private (but add a note that they are not intended
to be used).
This is not a great name to use in themes; instead, add the
menuitem class, so themes can use .button.menuitem for styles
that are specific to menuitem-like buttons.
We were not really handling all cases correctly here. We want
the suggested-action style class to only be set on headerbar
buttons, and it should be set on the default widget. Ensure
this by syncing the suggested-action style class with the
default style class. As a side-effect, setting has-default
on an action widget in ui files will now have the expected
effect.
https://bugzilla.gnome.org/show_bug.cgi?id=728846
GtkDialog has convenience API for adding action widgets that are

The documentation for the GtkWidget::size-allocate signal is missing the
description of the "allocation" parameter. Add the missing description
to the parameter.
https://bugzilla.gnome.org/show_bug.cgi?id=726179
Use GSlice to allocate all types of segments:
- char
- toggle
- mark
- pixbuf
- child widget
Char segments are a bit more complicated because the length of the text
is determined at run time and stored in the 'byte_count' field. If the
text is long, GSlice will call the system malloc() anyway, so it's
better to always use GSlice for GtkTextLineSegment.
Toggle segments are also freed in gtktextbtree.c, hence the function
_gtk_toggle_segment_free() (for a later commit it would be nice to
rename those functions with the _gtk_text prefix).

There is a possible confusion with the sentence:
"@iter is inside a natural-language word"
The iter should be viewed here as the pointed character (i.e. on the
right of the iter), not as a position between two characters.
Instead of improving the documentation, another solution would have been
to change the implementation so it is interpreted as an iter position
inside a word, i.e. between two characters that are part of a
natural-language word. But maybe some applications rely on the current
implementation.

We are using the actionbar in the middle of the window, which
is not really what it is designed for. To avoid the unfinished
appearance on the sides, move it into the frame that we have

The text view is resizing several times after the window is mapped.
Not setting a hscrollbar-policy of never avoids that, and a

The incremental loading was broken by GtkIconHelper - queuing a

The use of border-width-set here was an attempt to differentiate
between explicitly set (from code / ui files) border width from
theme changes. But when we are calling gtk_window_set_border_width
to apply the theme value, the -set property gets set, and all
further theme changes are ignored. This has the effect of only
letting the default value of these properties get applied.
Fix this by unsetting border-width-set after applying theme values.
Because GTK does not invalidate windows that aren't mapped, we cannot
update the pixel cache when the window it handles isn't mapped. So we

Add support to build the introspection files for GdkWin32, as done recently
in the autotools builds and clean up the NMake Makefile for building the

For some reason, gdk_win32_display_manager_get_type() was not exported in
gdk-3.0.lib, force its export, so that the GdkWin32-3.0.gir can be built

* Makes listbox background white instead of default grey
* Uses gradients or W32 theme parts to draw sexy selection/prelight

text color though. This partially fixes text color propagation from

...on Windows 8+ and when the system setting for non-Unicode programs do

GTK_TREE_VIEW_TIME_MS_PER_IDLE is currently 30 milliseconds, meaning
that validate_rows will validate rows up until all the validations have
taken over 30 msecs. So it's likely to block redrawing via the clock
frame update mechanism, as that tops at 16.66 milliseconds per frame
(1/60th of a second).
Stop validating rows if we've spent more than 3/5 of our allotted budget
for inter-frame processing, so as to avoid blocking.
In the future, we would probably want to calculate how long we would
have left until the next frame, especially if higher priority idles
and timeouts have already consumed a portion of that allotted time.

The compositing that is meant here is really specific to the

This is very rarely used functionality anyway, and none of

This fixes an issue where the theme-provided border-width prevents
dialog contents from lining up properly with the headerbar. To make

width of the action area to 0.
In select-folder mode, we are putting the directory name into the

Widgets should only call set_realized() after having created and
registered their GDK windows. In this case, the creation of the style

We had a margin of 30 before/after the text. Put that add around
the icon as well, and separate the icon and text by 30 pixels.
This does not affect the appearance of message dialogs without
icons.
It seems that some backends implemented get_root_origin wrong
and returned the client window coordinates, not the frame window
coordinates. Since it's possible to implement generically for all
windows, let's do that instead of having a separate impl vfunc.
Lots of code, including dragging code in GtkWindow, use these
fields. Setting them to 0 causes lots of strange and weird bugs.
Use the same "hack" from query_device_state of just using
win_x / win_y for now. We'll convert this to the proper fake root
coordinate system used by get_root_coords in the next commit.
If a textview had lateral windows that might displace the text window, the
handles and popovers would appear displaced. Those lateral windows aren't
affected by RTL/LTR settings, so just checking for left/top is ok here.
And the counterpart to unmaximize when dragging a maximized window, if
touch devices aren't going to use EWMH moveresize, having this one at least
makes things feel a bit less awkward.
https://bugzilla.gnome.org/show_bug.cgi?id=709914
Sadly, EWMH moveresize mechanism can't work with touch devices for two
reasons:
1) As a mutter implementation detail, the device is queried in order
to check whether the dragging button is still pressed. Touch devices
won't report the button 1 being pressed through pointer emulation.
2) Even bypassing that check, on X11 touch events are selected prior
to sequences being started, either through XISelectEvents or
XIGrabTouchBegin, no late registering through active grabs is allowed,
as WMs do on reaction to EWMH moveresize messages.
So for the time being, make touch devices fallback on emulated window
dragging, which at least allows for moving windows.

We want to present a clean, rounded top when there is nothing
else to show, but many dialogs in applications rely on showing
information in their title, so add a label and show the title
when it is not empty.
Add gdk_device_get_last_event_window(), and use to implement the window
tracking we need for synthesizing crossing events for sensitivity changes
and gtk grabs, rather than keeping the information in qdata and updating
it based when GTK+ gets events.
https://bugzilla.gnome.org/show_bug.cgi?id=726187
Stop ignoring various crossing events from grabs:
Enter events with type GRAB/GTK_GRAB/GTK_UNGRAB/STATE_CHANGED:
Ignoring these events was added as a workaround for synthesized
events not having the right coordinates (see bug 555109) but
now they do have the right coordinates. (see bug 704456)
Leave events with types types GTK_GRAB/GTK_UNGRAB:
Ignoring these events was added because since we were ignoring
the enter events as above, ignoring the leave events meant we
could lose the prelighted row in a grab-triggered leave/enter
pair. (See bug 653676. It's also now impossible to
reproduce the leave events that were reported in that bug as causing
problems.)
Leave events of type GRAB.
Ignoring these events was added without a ChangeLog entry in 2001,
possibly to keep the prelight from flashing when activating menus.
But ignoring these events could lead to stuck prelighting, and we don't
do it for any other widgets.
https://bugzilla.gnome.org/show_bug.cgi?id=726209
The bug this patch is fixing is that currently if you have a GtkPopover in
clicking off the popover to dismiss it on a GtkTreeView (which triggers
a synthetic enter event on the GtkTreeView) will leave the GtkTreeView
in a confused state until the user moves the mouse again.
That doesn't make sense.
And it causes issues, because when holding down the tab key, we
show/hide a lot of windows and cause a lot of map/unmap events that
stall the event pipeline.
We did not set an input shape on the window, so the region outside
the invisible border where we draw the outer edges of the shadow
were still part of the window, as far as clicks and cursors were
concerned. Fix this by setting an input shape that makes all clicks
outside of the resize borders go through to the underlying window.

window->x / window->y are in "root window coordinates", e.g. relative
to the topmost toplevel. However, the coordinates in get_xdg_popup are
relative to the passed-in surface, so we need to do the reverse
translation here.
As discussed on desktop-devel-list [1], "There should be an intuitive,
consistent, immediate way to jump to the widgets that live in the
header bar." F10 has been suggested for this as it is already used to
active menubars.
F10 will focus the custom titlebar widget if the window has one and it
isn't already focused. If the titlebar widget doesn't exist or is
already focused then F10 focuses the menubar if there is one.

We have a hack in the XSETTINGS code to substitute gtk-xft-dpi
with gdk-unscaled-dpi unless the screen has a fixed window scale,
in which case we just use gtk-xft-dpi.
But if the screen is changed to have a fixed window scale, then
the substituted value of gdk-unscaled-dpi will stick around until
the next (coincidental) change to XSETTINGS. To fix this, force
an immediate reread of the XSETTINGS property when

It may be unusual, but handlers of day-selected may want to transfer
focus somewhere else, without getting it reset back right after by/to
the calendar. This makes popovers demo work on the calendar again, for
one...
Make the popover temporarily undo the GTK+ grab, so it remains modal
to its window, but does not attempt to steal focus on other non-modal
windows that get the focus.
This was most confusing with keyboard navigation, as the focus would
remain stuck on the popover, and not move to the newly focused window
after the popover was dismissed. It didn't have as much effect on
pointer operations as only the first click would be consumed in order
to hide the popover.
There are early returns in this method before the completion timeout
is set later on, so set the source to 0 to avoid trying to remove it
later again.

This is not necessary for the popover itself, but helps tooltips

The point of GdkWindowImpl::get_root_coords is to translate the passed
in coordinates against the passed-in impl window. For a child window,
in fact, window->abs_x and window->abs_y already track the child
window's coordinates against the impl window.
If we pass in a child window, and backends don't explicitly get the impl
window from it, we'll double-count the child window.
Really, we should *always* be passing impl windows to backends, and
never child windows. However, I'm a bit worried for regressions late
in the cycle if we want to fix up the rest of the callers, like
gdk_window_get_geometry, so I'm only going to touch get_root_coords
for now after careful review of all the backends.
GtkWindow calls set_shadow_width then maps the window, meaning
that we never set the margin. Save it when we set and then set
it when we create the XDG surface.
In the unlikely case that there is another GPL released in the future
it would be best if we link directly to the 3.0 version of the
license description instead of the alias to the latest
version.
Old code assumed that AT-SPI would keep track of references and
therefore tried to only hold weak references. On the other hand it also
tried to keep objects alive so it referenced objects very randomly. All
of that lead to cycles and leaking.
As AT-SPI does not keep track of objects at all, the treeview now does.
The refcounting looks as follows:
GtkTreeViewAccessible
=> creates per row/column
GtkTreeViewAccessibleCellInfo
=> which references 1
GtkCellAccessible
If there is only one cell, this accessible is a
GtkRendererCellAccessible, otherwise a GtkContainerCellAccessible is
created and that accessible holds references to the
GtkRendererCellAccessibles that are created for every cell renderer.

GObject-Introspection was recently changed to support acquiring the name of
the DLL from a library (.lib, etc) that was passed into g-ir-scanner on
Windows, like the *nix builds, instead of directly passing in the name of

This updates the introspection build process, so that introspection files
for GTK+ can continue to be properly built.
The code in GDK is incredibly broken and nobody is quite sure what's
right-side-up and what's upside down, but this breaks mutter-wayland
now, so let's remove it. It might leak, but we should probably do a
full restructuring of GDK drawing to fix it.
Like in other backends (except X) we can't resize cairo image surfaces
so let's sync the code here with what the other backends do.

The new() function is supposed to return an empty fully initialized
GtkCssKeyframes object, while the alloc() function just allocates and

Fixes a memleak when resolving keyframes.
With the code as written, use-popover has to be set first,
before the model. To avoid this ordering dependency, re-set
the model when use-popover changes.
The convention we follow is that the PROP_foo define should
match the property name. Therefore, change PROP_MODEL to
PROP_MENU_MODEL to match "menu-model".
gtk_tree_view_remove_column was first removing the column from
its list, then call gtk_tree_view_column_unset_tree_view, which
would then call gtk_container_remove to remove its button from
the treeview. But the treeview remove implementation relied
on the column being still in the list in order to recognize
the button as 'special', so in effect the button was never
properly removed and thus, leaked.
Fix this by callling unset_tree_view before removing the
column from the list.

In practice this shape is only used to outline the popover when it is

visibly, so popovers will still be able to cast a shadow there.
If there are native windows below the popover, the shape will exclude the
shadow, so there are no alpha contents above the window. One worst case that
might happen is that the popover lays above patches of native/client-side
windows, so the shadow could come and go around the border. But first let's
see whether that happens often or visibly enough before adding something more
convoluted.
The update of the needs-attention state is done via its own property,
so it doesn't need to be done via visibility changes.
This patch is largely the result of inspecting the code due to a warning
and not a result of testing. So if issues pop up that bisect back to
this patch, that's why.
