Issue #5676 found a case where GTK tried to focus a widget with
a NULL GtkRoot. That specific case was a GtkButton which was a
GtkExpander's child, and until the GtkExpander is expanded (and
thus the GtkButton becomes visible) the button has no GtkRoot,
yet GTK tried to focus on it when GtkExpander's code called
gtk_widget_focus_child() on it.
We could change GtkExpander code to check if widget has no GtkRoot
and in that case avoid calling gtk_widget_focus_child(), but
it seems generally better to handle this at GtkWidget level so
it may cover other widgets that could misbehave in a similar way
as GtkExpander.
So in this patch:
We turn a critical message (failed assertion) into a proper warning
which informs the user about the non-allowed action.
We also make sure gtk_widget_focus_child() properly returns FALSE
when called on an unrooted widget.
Fixes#5676
Calling gtk_list_box_remove_all() is a no-op with a bound model; after
the introduction of the remove_all() method in 49e56fc7, we were left
with row widgets after the dispose() call chained up.
We could restore the explicit unparenting inside dispose() instead of
calling remove_all(), but since the bound list model is provided by the
user of GtkListBox, it's more appropriate to unbind it in the dispose()
implementation, to avoid any potential reference cycle (especially in
higher level languages that have no explicit reference acquisition).
We clean up the bound model, and its associated state, if any; and then
we remove all the row widgets that are left.
Basically what GL does, but without any debug or feature flag
to gatekeep it, since the Vulkan backend itself is experimental
already.
Ceil surface sizes, and floor coordinates, to the fractional scale
value.
The rects passed to the clip region are in buffer coordinates, and
must not be scaled. Consider the following scenario: Wayland, with
a 1024x768@2 window. That gives us a 2048x1536 raw image. To setup
the Vulkan render pass code, we'd scale 2048x1536 *again*, to an
unreasonable 4196x3072, which is (1) incorrect and (2) really
incorrect and (3) can lead to crashes at best, full GPU resets
at worst - and a GPU reset is incredibly not fun!
Now that we pass the right clip regions at the right coordinates
at all times, remove the extra scaling from the render pass.
This part of the Vulkan renderer is almost exactly equal to the GL
renderer, and the GL renderer already does that since at least
2a38cecd33. Copy that into the Vulkan renderer.
A nice side effect from this commit is that resizing a window now
actually works again.
Sneak in a trivial cleanup by using a variable to hold the draw
index.
This was a tricky one to figure out, but it's pretty simple to
understand (I hope!).
So, this AMD card I'm using requires buffer memory sizes to be
aligned to 16 bytes. Intel is aligned to 4 bytes I think, but
AMD - or at least this AMD model in particular - uses 16 bytes
for alignment.
When creating a a particular texture (I did not determin which one
specifically!) a buffer of size 1276 bytes is requested.
1276 / 16 = 79.75, which is clearly not aligned to the required
16 bytes.
We request Vulkan to create a buffer of 1276 bytes for us, it
figures out that it's not aligned, and creates a buffer of 1280
bytes, which is aligned. The extra 4 bytes are wasted, but that's
okay. We immediately query this buffer for this exact information,
using vkGetBufferMemoryRequirements(), and proceed to create actual
memory to back this buffer up.
The buffer tells us we must use 1280 bytes, so we pass 1280 bytes
and everyone is happy, right? Of course not. We pass 1276 bytes,
and Vulkan is subtly unhappy at us.
Fix that by passing the value that Vulkan asks us to use, i.e.,
the size returned by vkGetBufferMemoryRequirements().
This is what GL does, and for a reason: it can lead to width or
height for very small glyphs. Also, switch to dividing by a float
(1024.0) instead of an integer (1024).
This doesn't make any difference now, but will allow us to copy
subregions more easily. This is not obvious, but here's a quick
explanation:
Leaving 'bufferRowLength' and 'bufferImageHeight' implies that
Vulkan will assume the size passed in the 'imageExtent' field.
Right now, this assumption is correct - the only user of this
function is the glyph cache, and it only copies and uploads
exact rects. Next commits will change that assumption, so we
must pass 'buffer*' fields, and tell Vulkan, "this part of the
buffer represents an image of width x height, and I want the
subregion (x, y, smallerWidth, smallerHeight) of this image".
When creating an image using gsk_vulkan_image_new_for_framebuffer(),
it passes VK_IMAGE_LAYOUT_COLOR_ATTACHMENT_OPTIMAL.
However, this is a mistake. The spec demands that the initial
layout must be either VK_IMAGE_LAYOUT_UNDEFINED or
VK_IMAGE_LAYOUT_PREINITIALIZED.
Apparently this was an oversight from commit b97fb75146, since the
commit message even documents that, and all other calls pass either
VK_IMAGE_LAYOUT_UNDEFINED or VK_IMAGE_LAYOUT_PREINITIALIZED.
Create framebuffer images using VK_IMAGE_LAYOUT_UNDEFINED, which is
what was originally expected.
Removing all items from containers is a common use case.
Without this applications needed to implement this manually.
It makes senses to handle it here.
Fractional scaling with the GL renderer is
experimental for now, so we disable it unless
GDK_DEBUG=gl-fractional is set.
This will give us time to work out the kinks.
This commit combines changes in the Wayland backend,
the GL context frontend, and the GL renderer to switch
them all to use the fractional scale.
In the Wayland backend, we now use the fractional scale
to size the EGL window.
In the GL frontend code, we use the fractional scale to
scale the damage region and surface in begin/end_frame.
And in the GL renderer, we replace gdk_surface_get_scale_factor()
with gdk_surface_get_scale().
Whenn setting gtk_builder_set_allow_template_parents(), the builder
instance will accept
<template class="GtkWidget">
for a GtkBox instance.
It's going to be used with the new GtkColumnViewCell objects, so that
it's backwards compatible with ui file factories that use GtkListItem.
That way, local scrolling is available and the scrolling isn't random.
Recycling should now involve reordering the recycled widgets instead of
just keeping their order because all of them got recycled.
This allows setting a factory to toggle per-row properties.
Implemented are selectable, focusable and activatable.
These are meant to supercede the per-cell selectable and activatable
properties, which make no sense individually.
The focus property makes it possible to focus rows instead of cells,
which is the default behavior.
There is no way to set it yet, this is just to prove that it works.
It also changes the focus behavior of rows. They are now always
focusable - unless turned off by the factory once that is possible.
This makes the question if a listitem can be focused or not an explicit
decision by application developers.
Previously an item could be focused if it was selectable and no child or
grandchild was focusable - so if you put a label and icon into it, the
item was focusable, but if you put a GtkTreeExpander or a GtkButton into
it, the item wasn't. This needs to be decided explicitly now.
Technically this is an API break, because the previous behavior does not
exist anymore.
But I really don't want to make this a tristate (focusable, not
focusable, automatic), because then binding it to other things gets
hard, and because all the other focusable proeprties are booleans, too,
and working with them gets a lot harder.

Cairo can do that, so just enable it:
* Create surfaces with the correct fractionally scaled size.
* Set the Cairo surface's device scale to that number.
Instead of setting the buffer scale via the buffer-scale command, set it
via the viewport.
This technically allows setting fractional scales, but we're not doing
that.
Instead of tracking a single scale, track x and y scales separately.
Factor out gsk_vulkan_render_pass_new() into a private function that
receives both scales, and pass 'scale_factor' for both.
April fools!
No, really.
The fractional scale protocol is just a way to track the surface scale,
but not a way to draw fractional content.
This commit uses it for that, so tht we don't rely on tracking outputs.
This also allows magnifiers etc to send us a larger (integer) scale if
they would like that, that is not represented by the outputs.
This is mostly a cosmetic change, and the goal is twofold:
1. Make it easier to spot unimplemented render node types; and
2. Prepare for a small rework
The implementation for each node now lives in specific functions,
like the GL renderer; unlike the GL renderer, however, we use a
node type vtable to map GskRenderNodeType → implementation. Render
node without an implementation map to NULL, and use the fallback
implementation. Render nodes that fail any check and return FALSE
also use fallback implementation.
The scrolling code assumes the adjustment values are up to date or
it crashes and before we've run size_allocate() we haven't update them.
Fixes a crash in the gtk-demo scrollinfo that would set the adjustments
with random values (via ScrolledWindow.set_child()) and then scroll in a
tick callback right before the (first) size_allocate().
The Lunarg validation layers seem to have been deprecated in favour
of the Khronos ones. There's no reason not to have both, to accept
loading both - simultaneously, even.
Instead of passing a single, potentially massive rectangle that is
just the extents of the damage rect, collect and pass all damage
rects individually.
Add a new flag to track whether buffer scale is dirty or not,
and centralize calling wl_surface_set_buffer_scale() in a single
place: gdk_wayland_surface_sync_buffer_scale().
gdk_wayland_surface_sync_buffer_scale() is only called by
gdk_wayland_surface_sync(), which itself is called by the GL,
Vulkan, and Cairo contexts, right before submitting a frame.
This ensure that each frame has an up-to-date buffer scale.
This mimics how opaque and input regions are tracked.
According to the at-spi2 docs, for a widget to be considered visible,
it needs both the showing and visible states. Many applications rely on that,
for example the flat review functionality of Orca.
this fixes#5194
Don't fudge around poking through the listview, trying to get a model
and selecting it directly. Instead, use the proper way and activate the
"listitem.select" action.
Instead of directly calling select_item(), trigger the select-item
action of the focused child.
We do this convoluted calling into the widget because that way
GtkListItem::selectable gets respected, which is what one would expect.
Plus, this code is usually triggered via keybindings, and this way the
ListBase keybindings work identical to the ListItem keybindings.
If we encounter a node or texture the 1st time and they are going
to be used again, give them a name.
Then, when encountering them again, print them by name instead
of duplicating them.
We extend the syntax for nodes from:
<node-type> { ... }
to
<node-type> { ... }
<node-type> <string> { ... }
<string>;
where the first is the same as before, the 2nd defines a named node and
the last references a previously defined node.
Or to give an example:
color "node" {
bounds: 0 0 10 10;
color: red;
}
transform {
bounds: 20 0 10 10;
child: "node";
}
This will draw the red box twice, once at (0,0) and once at
(20,0).
The intended use for this is both shortening generated node files as
well as allowing to write tests that reuse nodes, in particular when
dealing with caches.
We extend the syntax for textures from just:
<url>
to
[<string>] <url>
<string>
where the first defines a named texture while the second references a
texture.
Or to give an example:
texture {
bounds: 0 0 10 10;
texture: "foo" url("foo.png");
}
texture {
bounds: 20 0 10 10;
texture: "foo";
}
This will draw the texture "foo.png" twice, once at (0,0) and once at
(20,0).
The intended use for this is both shortening generated node files as
well as allowing to write tests that reuse textures, in particular when
mixing them in texture and texture-scale nodes.
If we map, reposition, unmap, remap, the reposition feedback from the
last time a popup was mapped might be received while we're dealing with
the new version of the popup. At this point, the old reposition token
has no meating, so lets drop it. Also reset the reposition tokens when
creating new protocol objects, so that the reposition token are as if
we're in the initial state.
This fixes an issue where we'd get stuck if repeatedly smashing a button
that'd create popups that'd immediately get dismissed by the compositor.
Since Wayland 1.15, it is now possible to use absolute paths in
"WAYLAND_DISPLAY".
In that scenario, having a valid "XDG_RUNTIME_DIR" is not a requirement
anymore.
For this reason we remove the "XDG_RUNTIME_DIR" check and we let
`wl_display_connect()` decide if our environment is correct.

An inert gridview is a gridview that does not use the factory. This
allows faster updates because no calls into user code need to happen.
A gridview is inert when either:
- It is not rooted.
- It is not visible.
- No factory is set (that one is obvious)
The gridview does not need to be inert without a model, as that case is
handled by the item manager.
This should allow Nautilus to keep both the gridview and the columnview
around, and just gtk_widget_hide() the unused widget.
The code for now does not disable the item manager, as some
functionality of the item manager is required to allow setting scroll
positions and such.
But that is a place where more gains could be found if profiling showed
that was useful to do.

The widget would teardown the factory on unroot to avoid unnecessary
work when it isn't shown.
However, recycling may reposition widgets, and repositioning widgets
does a unroot/root.
We don't want to recycle widgets then.
The implementation lives (as always) in GtkListBase.
This is a feature request from the Nautilus developers, who currently do
some hacks to emulate that behavior and it apparently only breaks
sometimes.
We connect gtk_scrolled_window_update_use_indicators
as signal handler in realize(), but we were disconnecting
gtk_scrolled_window_sync_use_indicators in unrealize.

Just like GdkToplevel::compute-size, the size argument of the signal is
given to the handlers by GDK; it's not an out argument meant to be
allocated by the caller.
The size argument is passed to the signal by the GDK surface machinery,
as is: it's not going to be allocated by the caller (since it's a
signal), and it's not an out argument.
The cursor-theme-size setting is documented as
'0 means the default size'. Make it so by using
size 24 if we see a 0. Its better than crashing.
Fixes: #5700
The function is going away, and the computation
here was wrong anyway. Instead, add a helper that
properly computes the pointing-to rect in surface
coordinates and use it everywhere.
The widget paintable uses the widgets bounds
as intrinsic size, so we need to offset from
that to the allocation, which is what the
coordinates are relative to.
Text handles had the same problem as popovers.
They were interpreting their pointing-to rectangle
relative to the widgets bounds, when it is meant
to be relative to the widgtets allocation.
While we touch this code, rewrite it to use
gtk_widget_compute_point.
When we don't have a pointing-to rectangle, we want to place
the popover wrt to the parents bounds. But if we have a
pointing-to rectangle, it is relative to the widgets allocation,
which is different from the bounds.
We were not handling the second case correctly, leading to context
menus in the text view being mispositioned by the widgets CSS padding.
While we are touching this code, rewrite it to handle transforms.
Fixes: #5695
Since we are making GdkGLContext call the core wgl*() functions directly
instead of via libepoxy, drop the workarounds that we needed for notifying
libepoxy that wglMakeCurrent() outside of GDK/GTK was called.
This way, we clean up the code, and as a result, we can use the GstGL
APIs like the other platforms to query what GL api that is to be used.
For ensuring that things work between different threads, we now call
gdk_gl_context_clear_current() in place of calling wglMakeCurrent(xxx,
NULL), so that we make sure that there is no current GL context on a
thread outside of GstGL's thread, which Windows does not like.
We might be dealing with GL contexts from different threads, which have more
gotchas when we are using libepoxy, so in case the function pointers for
these are invalidated by wglMakeCurrent() calls outside of GTK/GDK, such as
in GstGL, we want to use these functions that are directly linked to
opengl32.dll provided by the system/ICD, by linking to opengl32.lib.
This will ensure that we will indeed call the "correct" wgl* functions that
we need.
This should help fix issue #5685.
When the GL texture already has a mipmap, we don't
have to download and reupload it to generate one.
We differentiate the handling for texture scale nodes,
where we do want to force the mipmap creation even if
it requires us to reupload the GL texture, and plain
texture nodes, where we just take advantage of a
preexisting mipmap to allow trilinear filtering for
downscaling, or create one if we have to upload the
texture anyway.
Make GdkGLTexture determine if the texture has
a mipmap, and provide private API to query this
information.
This check is done in gdkgltexture.c instead of
gskgldriver.c, since we're already binding the
texture here for other reasons, so it is easy
to query a few more things.
- grab_focus() on a row (happens with scroll_to()) keeps the focus
column intact if possible.
- <Tab> and <Shift-Tab> move through the cells in order, and move
to the next row when at the end.
- <Up> an <Down> move to the next/prev row, keeping the same column
focused.
- <Left> and <Right> move to the prev/next cell, if one is available.
If not, they stay where they are.
Make it move focus just like GtkWindow would.
Otherwise the listview will (try to) handle it and move focus between
cells - which doesn't do anything for lists and only works with grids.
This is a split of GtkListItemWidget into the generic parts of factory
using widgets.
On top of it there's GtkListItemWidget, which takes care of GtkListItem.
They're not used outside of GtkListBase, so no use to have them in the
header.
Requires moving one function up in the source now that the forward
declaration is missing.
create_at_context was confused - it stored a reference
to the newly created context in priv->context, but then
also returned a reference, and the caller stored that
in priv->context again.
Change it to only return a reference.
Fixes: #5690
Store texture coordinates for each slice
instead of assuming 0,0,1,1, and generate
overlapping slices to allow for proper mipmaps.
This almost fixes trilinear filtering with
sliced textures.
This one exhaustively tests reusing the same model as a child model for
many nodes.
This tracks that multiple items-changed signals emitted at the same time
(or multiple handlers for one such signal) doesn't put the treelistmodel
in an inconsistent state while it is handling all of them.
I'm not sure this (ab)use of treelistmodel should be officially
supported, but it works today, so let's test it to see if we can keep it
working.
If there is no other widget in the group that we can focus, don't focus
and activate ourselves.
Otherwise the arrow keys on checkbuttons toggle the checkbutton.
If a GtkImage is using an icon we use a gtk-icon-filter to se the icon
opacity when in insensitive state, however when using other kinds of
pictures we do not apply the same style leading to an inconsistent
result.
Closes: #5683
Items should be cleared when the node is discarded, not when the node's
children are discarded - which can also happen when a node is collapsed.
Fixes an error introduced in 9048e391b6Fixes#5681
In constrast to our other tests, these use
textures that are big enough to force slicing
with setting GSK_MAX_TEXTURE_SIZE, which we
will use in the following commits to improve
test coverage.
It is useless to have node files with references
to external files in the testsuite, so turn such
textures into data urls by doing a serialization
roundtrip.
No user knows that we have an internal function called
gtk_tree_list_row_destroy() that gets called when a row gets removed
from the treelistmodel.
So everyone was probably just making stuff up about what "destroy"
means.
Related: #5646
That way, we can return the item even after the row is removed. This is
particularly relevant in ListItemFactory::unbind callbacks because they
often use gtk_tree_list_row_get_item() and user code never tracks
changes to this property.
A side effect of this is that the item will survive until the row gets
destroyed, but that's what users expect anyway, so we can live with it.
Related: #5646
This is a good idea to avoid reentrancy problems when any child model
(or potentially more than one child model) has started emitting
items-changed but the emission hasn't arrived in this model yet.
At tat point, we'd get_item() the wrong item from those models.
We want to avoid such cases of reentrancy.
Related: #5646
We cheat and just set the texture parameters instead and hope nothing
explodes.
So far it didn't.
This is only needed to support GLES 2.0 so it's quite a limited set of
hardware these days.
Instead of uploading a texture once per filter, ensure textures are
uploaded as little as possible and use samplers instead to switch
different filters.
Sometimes we have to reupload a texture unfortunately, when it is an
external one and we want to create mipmaps.
When filtering changes for an already-cached
texture, we need to clear the render data
before setting the new one, otherwise it
does not take and we end up reuploading
the texture every frame.
Code above ensures that i is always in [0, n_columns - 1] range, so
the condition was always true, which resulted in filler tile always
being added to the grid. As the result, an empty row appeared at the
end of the grid if the number of columns divided the number of items.
Only add filler tile if last row is not full, i.e. when i > 0.

The GtkUriLauncher calls into the openuri portal, which distinguishes
between files, directories, and URI. The GtkFileLauncher contains logic
to deal with this, because it can already handle the file and folder
differences.
If we have a file:// URI it's easier to create a GFile out of it, and
use the GtkFileLauncher API, while leaving the GtkUriLauncher API for
every other URI scheme.
Same fix as de3c1d0c73, for GtkLabel.

Otherwise GL surfaces that redraw without changing the hotspot have it
applied on top every frame and quickly slide away.
The cairo path and the X11 backend do not have this bug.
The GL Wayland drag surface code path has a bug where it does not reset
the hotspot, so if a GL-backed draw surface redraws without resizing or
resetting the hotspot, it moves away. The next commit will fix that, but
this commit adds a test for that.
Allow to set max texture size using the
GSK_MAX_TEXTURE_SIZE environment variable.
We only allow to lower the max (for obvious
reasons), and we don't allow values smaller
than 512 (since our atlases use that size).
GdkDragSurface-backed widgets are not parented to an existing widget,
unlike popovers, and like toplevels. This means that there's nobody to
actively call gdk_drag_surface_present() to update the size, and
GdkDragSurface should do it on its own, just like GdkToplevel.
This commit implements this for the Wayland backend.
Compute our size when requested by the backend. This makes GtkDragIcons
actually recompute their size when it changes, instead of getting stuck
with the first size and potentially underallocating.
Similarly to GdkToplevel, GdkDragSurface's compute-size should be called
by backends to query the current surface size, and should be connected
to by widget implementations (like GtkDragIcon) to report the current
size.

This allows dropping or copy/pasting rendernodes into apps that accept
SVGs.
Not sure how useful this is because we advertise text/plain from
rendernodes already and we prefer that.
Doing it on hide() is not enough, since in some edge cases we didn't
ever actually map, we just attempted to compute the size, e.g. in
response to a ConfigureNotify event, then the window was destroyed.

... and make the tile finding code use distance.
This also changes how gtk_list_item_manager_get_tile_at() finds the
right tile, so this is a custom commit for bisectability.
gtk_list_item_manager_get_nearest_tile() isn't used yet.
This way, listview and gridview don't need to check if the rect is out
of bounds and nothing is selected, a quick rectangle_intersect() does
the job for them.
Just get the position right and give them a height of 0px, that should
be good enough.
If we don't do that, code will think the item doesn't exist, which is
not what we want.
This state is used for visited link-like widgets.
It has no ARIA equivalent, e. g. can not be set programmatically, but it
exists in the browser environment as well.
When the folder changes, do not select the first item in the list,
so if the user enters a folder and then clicks the accept button,
the current folder is returned instead of the selected one.
To maintain consistency with the previous implementation, when a
folder in the path bar is clicked the previously-entered folder is
selected, and when the file chooser is in open file mode the first
item is always selected.

Nodes can be given a name by adding a string after the `<node-type>` in their definition. That same node can then be used further down in the document by specifying just the name identifying the node.
### Textures
Just like nodes, textures can be referenced by name. When definining the named texture, the name has to be placed in front of the URL.
