8596f7edc5 Plug same refcount leaks as in the X11 backend.
2000-05-17  Tor Lillqvist  <tml@iki.fi>

* gdk/win32/gdkevents-win32.c (gdk_event_translate): Plug same
refcount leaks as in the X11 backend.

* gdk/win32/gdkgc-win32.c (gdk_win32_gc_set_values): Logging
cosmetics.

* gdk/win32/gdkwindow-win32.c: Similar changes as in X11
backend. Add _gdk_windowing_window_destroy().

* gtk/gtkcolorsel.c: Include correct backend-specific header.
Don't use XColor unless on X11. (No GDK_VISUAL_STATIC_COLOR
either, but these probably do exist on nanox?)

* gtk/gtkhsv.c: Use G_PI (fresh from <glib.h>) instead of M_PI
which isn't necessarily defined by <math.h>.

* gtk/gtkobject.c (gtk_object_init): Don't go up the class
ancestry past GtkObject.

* gtk/gtktypeutils.h: Mark GTK_TYPE_IDENTIFIER for export/import
from DLL on Win32.

* gtk/gtk.def: Update corresponding to recent changes.

* gtk/makefile.{cygwin,msc}: Updates.

386ae20970 A bit of editing.
Fri May 12 18:46:51 2000  Owen Taylor  <otaylor@redhat.com>

	* docs/Changes-1.4.txt: A bit of editing.

	* gdk/gdkwindow.c (_gdk_window_clear_update_area)
	* gdk/x11/gdkwindow-x11.c (gdk_window_hide): Add a function
	to clear the update area for the window, and clear it
	when hiding a window.

	* gdk/gdkwindow.c (gdk_window_begin_paint_region): Ignore
	if window destroyed.

	* gdk/gdkwindow.c (gdk_window_end_paint): Likewise.

	* gdk/gdkwindow.c gdk/x11/gdkwindow-x11.c gdk/gdkinternals.h: Move
	gdk_window_destroy() to the generic code, since there was a lot of
	window-system-independent logic it in. Add a function:

	 _gdk_window_destroy()

	to the internal API to destroy a window without unreferencing it.
	Add a function:

	 _gdk_windowing_window_destroy()

	That does the windowing-system-dependent part of destroying
	the window.

	* gtk/testgtk.c: Fix various memory leaks of pixmaps.

Fri May 12 11:06:10 2000  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkwidget.c docs/Changes-1.4.txt (gtk_widget_shape_combine_mask):
	Make gtk_widget_shape_combine_mask() keep a reference count on
	the pixmap since it keeps it around.

Fri May 12 10:53:29 2000  Owen Taylor  <otaylor@redhat.com>

	* gdk/gdkwindow.c (gdk_window_process_updates_internal): Fix refcount

	leak with event filters.

Thu May 11 14:29:44 2000  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkdnd.c (gtk_drag_dest_set_internal): Remove the
	signal handlers with the right data arguments. (Fixes
	some warnings when a widget was repeatedly set as a drag
	destination.)

	* gdk/x11/gdkdnd-x11.c (gdk_window_register_dnd): Set data on the
	window so we can avoid avoid setting the DND properties on the
	toplevel window repeatedly.

cab7ca49d5 Define more message types missing from mingw headers.
2000-05-13  Tor Lillqvist  <tml@iki.fi>

* gdk/win32/gdkwin32.h: Define more message types missing from
mingw headers.

* gdk/win32/gdkevents-win32.c (gdk_event_translate): On WM_DESTROY
call gdk_window_destroy_notify(). It was never called. This
probably meant that the GdkWindow was never freed. Thanks Owen for
noticing (!).

* gdk/win32/gdkwindow-win32.c (gdk_window_internal_destroy): Mark
window as destroyed before calling DestroyWindow(). DestroyWindow()
causes a call to the window procedure (gdk_WindowProc), which
calls gdk_event_translate(), which calls
gdk_window_destroy_notify(), which gets confused unless the window
is set as destroyed.

* gdk/win32/gdkcolor-win32.c (gdk_win32_color_to_string): Rename
this function to indicate it's win32 only. Put inside #ifdef
G_ENABLE_DEBUG.

* gdk/win32/gdkevents-win32.c (gdk_win32_message_name): New
debugging function. (gdk_event_translate:) Add a default branch
that uses the above function to print debug messages with all
Windows messages symbolically.

* gdk/win32/gdkprivate-win32.h: Declare it, and
gdk_win32_color_to_string, but only if G_ENABLE_DEBUG.

Fri May 12 17:13:32 2000  Tim Janik  <timj@gtk.org>

	* docs/Changes-1.4.txt: documented necessary changes for 1.4 transition.

	* gtk/gtktext.c: made the adjustments no-construct args, simply
	provide default adjustments.
	(gtk_text_destroy): release adjustments.

	* gtk/gtkprogressbar.c (gtk_progress_bar_class_init): made the
	adjustment argument non-construct.

	* gtk/gtkprogress.c (gtk_progress_destroy): release adjustment here,
	instead of in finalize.
	(gtk_progress_get_text_from_value):
	(gtk_progress_get_current_text):
	(gtk_progress_set_value):
	(gtk_progress_get_percentage_from_value):
	(gtk_progress_get_current_percentage):
	(gtk_progress_set_percentage):
	(gtk_progress_configure): ensure an adjustment is present.

	* gtk/gtkcolorsel.[hc]:
	* gtk/gtkcolorseldialog.[hc]:
	* gtk/gtkhsv.[hc]: major code cleanups, destroy handlers need to chain
	their parent implementation, use bit fields for boolean values, don't
	create unused widgets, usage of glib types, braces go on their own
	lines, function argument alignment, #include directives etc. etc. etc..

	* gtk/Makefile.am (gtk_public_h_sources): install gtkhsv.h.

Wed May 10 23:29:52 2000  Tim Janik  <timj@gtk.org>

	* gtk/gtktoolbar.c (gtk_toolbar_destroy): don't unref a NULL tooltips.

	* gtk/gtkfilesel.c (gtk_file_selection_destroy): don't free a cmpl_state
	of NULL.

	* gtk/gtkcombo.c (gtk_combo_item_destroy): don#t keep references
	to freed data.
	(gtk_combo_destroy): don't keep a pointer to a destroyed window.

	* gtk/gtkmenu.c (gtk_menu_init): reset the menu's toplevel pointer
	to NULL when the toplevel is getting destroyed.
	(gtk_menu_set_tearoff_state): same here for the tearoff_window.
	(gtk_menu_destroy):
	(gtk_menu_init): store the information of whether we have to
	readd the initial child ref_count during destruction in a new
	GtkMenu field needs_destruction_ref_count.

	* gtk/gtkviewport.c: SHAME! ok this one is tricky, so i note it
	here, those reading: learn from my mistake! ;)
	in order for set_?adjustment to support a default adjustemnt if
	invoked with an adjustment pointer of NULL, the code read (pseudo):
	if (v->adjustment) unref (v->adjustment);
	if (!adjustment) adjustment = adjustment_new ();
	if (v->adjustment != adjustment) v->adjustment = ref (adjustment);
	now imagine the first unref to actually free the old adjustment and
	adjustment_new() creating a new adjustment from the very same memory
	portion. here, the latter comparision will unintendedly fail, and
	all hell breaks loose.
	(gtk_viewport_set_hadjustment):
	(gtk_viewport_set_vadjustment): reset viewport->?adjustment to NULL
	after unreferencing it.

	* gtk/gtkcontainer.[hc]: removed toplevel registration
	functions: gtk_container_register_toplevel(),
	gtk_container_unregister_toplevel() and
	gtk_container_get_toplevels() which had wrong semantics
	anyways: it didn't reference and copy the list.

	* gtk/gtkwindow.c: we take over the container toplevel registration
	bussiness now. windows are registered across multiple destructions,
	untill they are finalized. the initial implicit reference count
	users are holding on windows is removed with the first destruction
	though.
	(gtk_window_init): ref & sink and set has_user_ref_count, got
	rid of gtk_container_register_toplevel() call. add window to
	toplevel_list.
	(gtk_window_destroy): unref the window if has_user_ref_count
	is still set, got rid of call to
	gtk_container_unregister_toplevel().
	(gtk_window_finalize): remove window from toplevel list.
	(gtk_window_list_toplevels): new function to return a newly
	created list with referenced toplevels.
	(gtk_window_read_rcfiles): use gtk_window_list_toplevels().

	* gtk/gtkhscale.c (gtk_hscale_class_init): made the GtkRange
	adjustment a non-construct arg.
	* gtk/gtkvscale.c (gtk_vscale_class_init): likewise.
	* gtk/gtkhscrollbar.c (gtk_vscrollbar_class_init): likewise.
	* gtk/gtkvscrollbar.c (gtk_vscrollbar_class_init): likewise.

	* gtk/gtkrange.c: added some realized checks.
	(gtk_range_destroy): get rid of the h/v adjustments in the
	destroy handler instead of finalize. remove timer.
	(gtk_range_get_adjustment): demand create adjustment.

	* gtk/gtkviewport.c: made h/v adjustment non-construct args.
	we simply create them on demand now and get rid of them in
	the destroy handler.
	(gtk_viewport_destroy): get rid of the h/v adjustments in the
	destroy handler instead of finalize.
	(gtk_viewport_get_hadjustment):
	(gtk_viewport_get_vadjustment):
	(gtk_viewport_size_allocate): demand create h/v adjustment
	if required.

	* gtk/gtkwidget.c (gtk_widget_finalize): duplicate part of the
	gtk_widget_real_destroy () functionality.
	(gtk_widget_real_destroy): reinitialize with a new style, instead
	of setting widget->style to NULL.

Fri May  5 13:02:09 2000  Tim Janik  <timj@gtk.org>

	* gtk/gtkcalendar.c:
	* gtk/gtkbutton.c: ported _get_type() implementation over to
	GType, either to preserve memchunks allocation facilities,
	or because Gtk+ 1.0 GtkTypeInfo was still being used.

	* gtk/gtkobject.[hc]: derive from GObject. ported various functions
	over. prepare for ::destroy to be emitted multiple times.
	removed reference tracer magic. chain into GObjectClass.shutdown()
	to emit ::destroy signal.

	* gtk/gtksignal.c: removed assumptions about GTK_TYPE_OBJECT being
	fundamental.

	* gtk/gtkmain.c: removed gtk_object_post_arg_parsing_init()
	cludge.

	* gtk/gtksocket.c:
	* gtk/gtkplug.c:
	* gtk/gtklayout.c:
	* gtk/gtklabel.c:
	* gtk/gtkargcollector.c:
	* gtk/gtkarg.c: various fixups to work with GTK_TYPE_OBJECT
	not being a fundamental anymore, and to work with the new
	type system (nuked fundamental type varargs clutter).

	* gtk/*.c: install finalize handlers in the GObjectClass
	part of the class structure.
	changed direct GTK_OBJECT()->klass accesses to
	GTK_*_GET_CLASS().
	changed direct object_class->type accesses to GTK_CLASS_TYPE().

	* gtktypeutils.[hc]: use the reserved fundamental ids provided by
	GType. made most of the GTK_*() type macros and Gtk* typedefs
	simple wrappers around macros and types provided by GType.
	most notably, a significant portion of the old API vanished:
	GTK_TYPE_MAKE(),
	GTK_TYPE_SEQNO(),
	GTK_TYPE_FLAT_FIRST, GTK_TYPE_FLAT_LAST,
	GTK_TYPE_STRUCTURED_FIRST, GTK_TYPE_STRUCTURED_LAST,
	GTK_TYPE_ARGS,
	GTK_TYPE_CALLBACK,
	GTK_TYPE_C_CALLBACK,
	GTK_TYPE_FOREIGN,
	GtkTypeQuery,
	gtk_type_query(),
	gtk_type_set_varargs_type(),
	gtk_type_get_varargs_type(),
	gtk_type_check_object_cast(),
	gtk_type_check_class_cast(),
	gtk_type_describe_tree(),
	gtk_type_describe_heritage(),
	gtk_type_free(),
	gtk_type_children_types(),
	gtk_type_set_chunk_alloc(),
	gtk_type_register_enum(),
	gtk_type_register_flags(),
	gtk_type_parent_class().
	replacements, where available are described in ../docs/Changes-1.4.txt.
	implemented compatibility functions for the remaining API.

	* configure.in: depend on glib 1.3.1, use gobject module.

	"A over B" composite. This was clearly the intent, and it was easy
	to fix the code to do it. (Note to those that read my earlier tries
	at a patch; this version fixes typos that were present in all
	my patch attempts. I checked the final version by adding more tests.)

2000-05-02  Tor Lillqvist  <tml@iki.fi>

Large changes to the Win32 backend, partially made necessary by
the changes to the backend-independent internal
structures. Attempts to implement similar backing store stuff as
on X11. The current (CVS) version of the Win32 backend is *not* as
stable as it was before the no-flicker branch was merged. A
zipfile with that version is available from
http://www.gimp.org/win32/. That should be use by "production"
code until this CVS version is usable. (But note, the Win32
backend has never been claimed to be "production quality".)

* README.win32: Add the above comment about versions.

* gdk/gdkwindow.c: Don't use backing store for now on Win32.

* gdk/gdk.def: Update.

* gdk/gdkfont.h: Declare temporary Win32-only functions. Will
presumably be replaced by some more better mechanism as 1.4 gets
closer to release shape.

* gdk/makefile.{cygwin,msc}: Update.

* gdk/win32/*.c: Correct inclusions of the backend-specific and
internal headers. Change code according to changes in these. Use
gdk_drawable_*, not gdk_window_* where necessary.

* gdk/win32/gdkdnd-win32.c: Use MISC selector for GDK_NOTE, not
our old DND.

* gdk/win32/gdkdrawable-win32.c (gdk_win32_draw_text): Don't try
to interpret single characters as UTF-8. Thanks to Hans Breuer.
Use correct function name in warning messages.

* gdk/win32/gdkevents-win32.c: Use correct parameter lists for the
GSourceFuncs gdk_event_prepare and gdk_event_check.
(gdk_event_get_graphics_expose): Do implement, use
PeekMessage. Thanks to Hans Breuer.
(event_mask_string): Debugging function to print an GdkEventMask.
(gdk_pointer_grab): Use it.

* gdk/win32/gdkfont-win32.c: The Unicode subrange that the
(old) book I used claimed was Hangul actually is CJK Unified
Ideographs Extension A. Also, Hangul Syllables were missing.
Improve logging.

* gdk/win32/gdkgc-win32.c: Largish changes.

* gdk/win32/gdkim-win32.c (gdk_set_locale): Use
g_win32_getlocale() from GLib, and not setlocale() to get current
locale name.

* gdk/win32/gdkprivate-win32.h
* gdk/win32/gdkwin32.h: Move stuff from gdkprivate-win32.h to
gdkwin32.h, similarily as in the X11 backend.

* gdk/win32/gdkwindow-win32.c (gdk_propagate_shapes): Bugfix,
assignment was used instead of equals in if test. Thanks to Hans
Breuer.

* gdk/win32/makefile.{cygwin,msc}
* gtk/makefile.{cygwin,msc}: Updates. Better kludge to get the
path to the Win32 headers that works also with the mingw compiler.

* gtk/gtkstyle.c: Include <string.h>.

marked as hints. This for instance fixes the annoying file and

2000-04-12  Federico Mena Quintero  <federico@helixcode.com>

	This comes from an excellent idea by Tim Janik (timj@gtk.org) to
	hook to the last unref operation.

	* gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
	function to set the last unref handler for a pixbuf.
	(gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
	It calls the pixbuf's destroy notification function and frees the
	GdkPixbuf structure itself.
	(gdk_pixbuf_unref): Use the last unref function of the pixbuf if
	available.

	* gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
	for the last unref handler and its user data.

	* gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
	g_new0() to allocate the pixbuf.

	* gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
	Fixed the call to gtk_signal_new() for the "frame_done" signal; it
	was not specifying the `frame' argument.

	* gdk-pixbuf/gdk-pixbuf-animation.c
	(gdk_pixbuf_animation_get_width): Fixed docstring.
	(gdk_pixbuf_animation_get_height): Likewise.
	(gdk_pixbuf_animation_get_num_frames): Likewise.
	(gdk_pixbuf_animation_get_frames): Likewise.

	* doc/gdk-pixbuf-sections.txt: Updated with the new functions and
	types.

	* doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.

	* doc/tmpl/scaling.sgml: Added the description for GdkInterpType.

	* doc/tmpl/refcounting.sgml: Updated with the information about
	the last unref handler.

	* doc/tmpl/*.sgml: Markup tweaks.

	* gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
	update the libtool version number for libgnomecanvaspixbuf as
	well.
	(libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
	as well, or the old ones won't work with the new stuff.  Also,
	renamed the modules as follows.

	* gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
	modules are called "libpixbufloader-<format>.so" instead of
	"libpixbuf-<format>.so".  They needed renaming so that the new
	loaders won't overwrite the old ones; even with the versioning
	stuff, the new .so symlink to the .so.1.0.0 would overwrite the
	old real .so file.

2000-04-11  Federico Mena Quintero  <federico@helixcode.com>

	Most of this patch is based on a patch by Havoc Pennington
	(hp@redhat.com) to make GdkPixbuf's structures opaque and to
	remove the libart dependency.

	* gdk-pixbuf/gdk-pixbuf.h: Removed the public structures.
	(GdkColorspace): New enum that for now only contains
	GDK_COLORSPACE_RGB.
	(GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy
	notification function.
	(GdkInterpType): New num with interpolation types.

	* *.[ch]: Replace the libart stuff with our own stuff.

	* pixops/*.[ch]: Likewise.

	* gdk-pixbuf/gdk-pixbuf-private.h: New file with the private
	declarations of the GdkPixbuf structures.

	* gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_new_from_art_pixbuf):
	Removed function.
	(gdk_pixbuf_get_format): Constify.
	(gdk_pixbuf_get_n_channels): Constify.
	(gdk_pixbuf_get_has_alpha): Constify.
	(gdk_pixbuf_get_bits_per_sample): Constify.
	(gdk_pixbuf_get_pixels): Constify.
	(gdk_pixbuf_get_width): Constify.
	(gdk_pixbuf_get_height): Constify.
	(gdk_pixbuf_get_rowstride): Constify.

	* gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_copy): New function to copy
	a pixbuf.

	* gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a
	bits_per_sample argument; currently only 8 bits per sample are
	supported.

	* gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_pixbuf):
	New accessor.
	(gdk_pixbuf_frame_get_x_offset): New accessor.
	(gdk_pixbuf_frame_get_y_offset): New accessor.
	(gdk_pixbuf_frame_get_delay_time): New accessor.
	(gdk_pixbuf_frame_get_action): New accessor.

	* gdk-pixbuf/gdk-pixbuf-render.c
	(gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid
	mask rectangle for pixbufs without an alpha channel, set the
	*mask_return to NULL.

	* gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify.

	* gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes.

	* gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some
	preconditions.  Maybe we should also check for the colorspace,
	bits per pixel, and such.
	(gdk_pixbuf_composite): Likewise.
	(gdk_pixbuf_composite_color): Likewise.
	(gdk_pixbuf_scale_simple): Likewise, and fail gracefully if we
	cannot allocate the new pixbuf.
	(gdk_pixbuf_composite_color_simple): Likewise.

	* gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render):
	Use art_rgb_rgba_affine() or art_rgb_affine() since we no longer
	have an ArtPixBuf.

	* gdk-pixbuf/io-bmp.c: Fix includes.

	* gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Fixed cast in
	an lvalue.

	* TODO: Populated.

	* configure.in: Removed checks for libart.

	* gdk-pixbuf/Makefile.am: Removed references to libart.
	(noinst_HEADERS): Added gdk-pixbuf-private.h.

	* gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Incremented
	the version number of the libtool library to indicate that this
	definitely is not compatible with the old usage.  I know you love
	me.  I know you do.

	* configure.in: Bumped version number to 0.7.0.

	* README: Updated.

	* gdk-pixbuf-config.in (--libs): We no longer require libart.

	* DEPENDS.libgdk_pixbuf: We no longer depend on libart.

	* gdk-pixbuf.spec.in: Updated, but I don't guarantee anything.

Gtk port to nano-X
STATUS
Once upon a time I got a few apps working, then started merging
the new features added by Owen (32 bit sizes for windows and buffering).
Since then I haven't found the time to work on it:-/
TODO
Finish internal window manager abstraction or add proper support in nano-X.
Fix event polling.
Implement GdkImage, GdkRgb stuff.
Put generic region code in generic gdk and/or use the region code from nano-X.
Fix ugly automake stuff for make dist.
TODO in nano-X
We need to be able to clip and change the background of windows at runtime
for apps to not look so ugly!
Fonts: wait for better nano-X font implementation.
Properties on windows.
If you want to work on this port or get additional informnation, get in
touch with me.
To get the beast to compile you also need to apply the patch below
(any auto* wizard here?): the issue of having two gtk libraries in the
system needs to be addressed too, maybe use libgtk-x11-1.4.so and
libgtk-nanox-1.4.so ...

The GtkText widget is badly in need of replacement, since it is

of possible candidates for a replacement, with the most
promising at the current time being Havoc Pennington's
(hp@redhat.com) port of the Tk Text widget.
The GtkText widget is badly in need of replacement, since it
is buggy and insufficiently feature rich. This is being done
using Havoc Pennington's port of the Tk Text widget.
</p>
<p>
As part of this job it will be necessary to add
<a href="http://www.pango.org">Pango</a> support to the
replacement. The structure of the Tk text widget port seems
suited to this as it works paragraph-by-paragraph, and
Pango works at a sub-paragraph scale.

support is being added to the replacement. The structure of
the Tk text widget port is suited to this as it works

incremental reflow to make performance acceptable and to
implement embedded pixmaps and widgets.

Incompatible Changes from GTK+-1.2 to GTK+-1.4:
- The gdk_time* functions have been removed. This functionality
* The gdk_time* functions have been removed. This functionality
has been unused since the main loop was moved into GLib
prior to 1.2.
- The signature for GtkPrintFunc (used for gtk_item_factory_dump_items)
* The signature for GtkPrintFunc (used for gtk_item_factory_dump_items)
has been changed to take a 'const gchar *' instead of 'gchar *', to
match what we do for glib, and other similar cases.
- The detail arguments in the GtkStyleClass structure are now 'const gchar *'.
* The detail arguments in the GtkStyleClass structure are now 'const gchar *'.
- gtk_paned_set_gutter_size() has been removed, since the small handle tab
* gtk_paned_set_gutter_size() has been removed, since the small handle tab
has been changed to include the entire area previously occupied by
the gutter.
- GDK no longer selects OwnerGrabButtonMask for button presses. This means
* GDK no longer selects OwnerGrabButtonMask for button presses. This means
that the automatic grab that occurs when the user presses a button
will have owner_events = FALSE, so all events are redirected to the
grab window, even events that would normally go to other windows of the
window's owner.
- The detail arguments in the GtkStyleClass structure are now 'const gchar *'.
* GtkColorSelectionDialog has now been moved into it's own set of files,
gtkcolorseldialog.c and gtkcolorseldialog.h.
- Inserting and deleting text in GtkEntry though functions such
as gtk_entry_insert_text() now leave the cursor at its original
position in the text instead of moving it to the location of
the insertion/deletion.
* gtk_widget_shape_combine_mask() now keeps a reference count on the
mask pixmap that is passed in.
- The ->label field of GtkFrame widgets has been removed. (As part of
a change to allow the arbitrary widgets in the title position.) The
text can now be retrieved with the new function gtk_frame_get_text().
* Type system changes:
- GTK_TYPE_OBJECT is not a fundamental type anymore. Type checks of the
style (GTK_FUNDAMENTAL_TYPE (some_type) == GTK_TYPE_OBJECT)
will not work anymore. As a replacement, (GTK_TYPE_IS_OBJECT (some_type))
can be used now.
- The following types vanished: GTK_TYPE_ARGS, GTK_TYPE_CALLBACK,
GTK_TYPE_C_CALLBACK, GTK_TYPE_FOREIGN. The corresponding GtkArg
fields and field access macros are also gone.
- The following type aliases vanished: GTK_TYPE_FLAT_FIRST,
GTK_TYPE_FLAT_LAST, GTK_TYPE_STRUCTURED_FIRST, GTK_TYPE_STRUCTURED_LAST.
- The type macros GTK_TYPE_MAKE() and GTK_TYPE_SEQNO() vanished, use of
GTK_FUNDAMENTAL_TYPE() is discouraged. Instead, the corresponding GType
API should be used: G_TYPE_FUNDAMENTAL(), G_TYPE_DERIVE_ID(),
G_TYPE_BRANCH_SEQNO(). Note that the GLib type system doesn't build new
type ids based on a global incremental sequential number anymore, but
numbers new type ids sequentially per fundamental type branch.
- The following type functions vanished/were replaced:
Old Function Replacement
gtk_type_query() - being investigated -
gtk_type_set_varargs_type() -
gtk_type_get_varargs_type() -
gtk_type_check_object_cast() g_type_check_instance_cast()
gtk_type_check_class_cast() g_type_check_class_cast()
gtk_type_describe_tree() -
gtk_type_describe_heritage() -
gtk_type_free() -
gtk_type_children_types() g_type_children()
gtk_type_set_chunk_alloc() GTypeInfo.n_preallocs
gtk_type_register_enum() g_enum_register_static()
gtk_type_register_flags() g_flags_register_static()
gtk_type_parent_class() g_type_parent() / g_type_class_peek_parent()
Use of g_type_class_ref() / g_type_class_unref() and g_type_class_peek()
is recommended over usage of gtk_type_class().
Use of g_type_register_static() / g_type_register_dynamic() is recommended
over usage of gtk_type_unique().
- The 'font' and 'font_set' declarations in RC files are now ignored. There
is a new 'font_name' field that holds the string form of a Pango font
description.
* Object system changes:
GtkObject derives from GObject, so is not the basic object type anymore.
This imposes the following source incompatible changes:
- GtkObject has no klass field anymore, an object's class can be retrived
with the object's coresponding GTK_<OBJECT>_GET_CLASS (object) macro.
- GtkObjectClass has no type field anymore, a class's type can be retrived
with the GTK_CLASS_TYPE (class) macro.
- GtkObjectClass does not introduce the finalize() and shutdown() methods
anymore. While shutdown() is intended for GTK+ internal use only, finalize()
is required by a variety of object implementations. GObjectClass.finalize
should be overriden here, e.g.:
static void gtk_label_finalize (GObject *gobject)
{
GtkLabel *label = GTK_LABEL (gobject);
G_OBJECT_CLASS (parent_class)->finalize (object);
}
static void gtk_label_class_init (GtkLabelClass *class)
{
GObjectClass *gobject_class = G_OBJECT_CLASS (class);
gobject_class->finalize = gtk_label_finalize;
}
- the GtkObject::destroy signal can now be emitted multiple times on an object.
::destroy implementations should check that make sure that they take this
into account, by checking to make sure that resources are there before
freeing them. For example:
if (object->foo_data)
{
g_free (object->foo_data);
object->foo_data = NULL;
}
Also, ::destroy implementations have to release object references that
the object holds. Code in finalize implementations such as:
if (object->adjustment)
{
gtk_object_unref (object->adjustment);
object->adjustment = NULL;
}
have to be moved into the ::destroy implementations. The reason for doing
this is that all object reference cycles should be broken at destruction
time.

<H2><A NAME="ss1.2">1.2 ¿Qué es GTK+?</A>
</H2>
<P>GTK+ es un pequeño y eficiente conjunto de <EM>widgets</EM>, diseñados
con un aspecto y sentir general a Motif. Contiene <EM>widgets</EM> comúnes
y algúnos <EM>widgets</EM> más complejos como una selección de
archivos, y <EM>widgets</EM> de selección de colores.
<P>GTK+ proporciona algunas características únicas. (No tengo conocimiento
de otra librería de <EM>widge>
<HR><H3>Transfer interrupted!</H3>
enos).
Por ejemplo, un botón no contiene una etiqueta, contiene un <EM>widget</EM>
hijo, que en muchas instancias será una etiqueta. Sin embargo, el
<EM>widget</EM> hijo también puede ser un <EM>pixmap</EM> (mapa de pixels),
imagén o cualquier combinación posible que desee el programador. Toda la
librería es así de flexible.
<P>
<H2><A NAME="ss1.3">1.3 ¿Qué es el + en GTK+?</A>
</H2>
<P>Peter Mattis informó a la lista de correo gtk:
<BLOCKQUOTE>
"Escribí originalmente gtk el cual incluía tres librerías,
libglib, libgdk y libgtk. Era caracterizado por una jerarquía de
<EM>widget</EM> plana. O sea, no podías derivar un nuevo
<EM>widget</EM> de uno ya existente. Contenía un mecanismo de
<EM>callback</EM> (llamada) más estándar en lugar del mecanismo
de señales ahora presente en gtk+. El + fue agregado para distinguir
entre la versión original de gtk y la nueva versión. Pueden pensar
en ello como una ampliación al gtk original que agrega características
orientadas o objetos."
</BLOCKQUOTE>

<P>Peter Mattis informó a la lista de correo gtk:
<BLOCKQUOTE>
"Pienso que la última vez que Spencer y yo hablamos al respecto nos
decidimos por GTK = Gimp ToolKit. Pero no estoy seguro. Sin embargo,
definitivamente no es GNU."
</BLOCKQUOTE>

<H2><A NAME="s2">2. Cómo encontrar, configurar, instalar y comprobar GTK+</A></H2>
<H2><A NAME="ss2.1">2.1 ¿Qué necesito para correr GTK+?</A>
</H2>
<P>Para compilar GTK+, todo lo que necesita es un compilador de C (gcc) y
el Sistema X Windows y librerías asociadas en su sistema.
<P>
<H2><A NAME="ss2.2">2.2 ¿Dónde puedo conseguir GTK+?</A>
</H2>
<P>El sitio canónico es:
<PRE>
ftp://ftp.gtk.org/pub/gtk
</PRE>
Por supuesto, cualquier espejo de ftp.gtk.org debe tener las últimas
versiones también.
<P>
<H2><A NAME="ss2.3">2.3 ¿Cómo configuro/compilo GTK+?</A>
</H2>
<P>Por lo general, todo lo que necesita es emititir los comandos:
<PRE>
./configure
make
</PRE>
en el directorio gtk+-version/.
<P>
<H2><A NAME="ss2.4">2.4 Cuando compilo GTK+ obtengo un error como: <CODE>make: file `Makefile' line 456: Syntax error</CODE></A>
</H2>
<P>Asegúrese de que utiliza GNU make (verifique con <CODE>make -v</CODE>). Hay
varias versiones extrañas y maravillosas de make por ahí, y no todas
manejan los <EM>Makefiles</EM> generados automáticamente.
<P>
<P>
<H2><A NAME="ss2.5">2.5 ¡He compilado e instalado GTK+, pero no puedo lograr que los programas se enlacen con él!</A>
</H2>
<P>Este problema se encuentra comúnmente cuando las librerías GTK+ no pueden
ser localizadas o tienen la versión incorrecta. Generalmente, el compilador
se quejará de un 'unresolved symbol' (símbolo no resuelto). Hay dos cosas
que necesita verificar:
<P>
<UL>
<LI>Asegúrese de que las librerías pueden ser encontradas. Usted desea editar
/etc/ld.so.conf para incluír los directorios que contienen las librerías
GTK, de manera que luzca como:
<PRE>
/usr/X11R6/lib
/usr/local/lib
</PRE>
Luego necesita correr /sbin/ldconfig como root. Puede encontrar que directorio
utiliza GTK al ejecutar
<PRE>
gtk-config --libs
</PRE>
Si su sitema no utiliza ld.so para encontrar librerías (como Solaris),
entonces tendrá que utilizar la variable de ambiente LD_LIBRARY_PATH
(o compilar el camino en su programa, lo cual no voy a cubrir aquí). Así
que, con un shell tipo Bourne usted puede hacer (si sus librerías GTK
están en /usr/local/lib):
<PRE>
export LD_LIBRARY_PATH=/usr/local/lib
</PRE>
y en un csh, usted puede hacer:
<PRE>
setenv LD_LIBRARY_PATH /usr/local/lib
</PRE>
</LI>
<LI>Asegúrese de que el enlazador está ha encontrado el conjunto correcto de
librerías. Si tiene una distribución de Linux que instala GTK+ (ej.
RedHat 5.0) entonces esta versión anterior puede ser utilizada. Ahora
(asumiendo que tiene un sistema RedHat), emita el comando
<PRE>
rpm -e gtk gtk-devel
</PRE>
También puede querer remover los paquetes que dependen de gtk (rpm le
dirá cuáles son). Si no tiene un sistema Linux RedHat, verifique
para estar seguro que ni
<PRE>
/usr/lib
</PRE>
ni
<PRE>
/usr/local/lib
</PRE>
contengan alguna de las librerías libgtk, libgdk, libglib, or libgck.
Si existen, elimínelas (y cualquier archivo <EM>include</EM>, como
/usr/include/gtk y /usr/include/gdk) y reinstale gtk+.</LI>
</UL>
<P>
<H2><A NAME="ss2.6">2.6 Cuando compilo programas con GTK+, obtengo mensajes de error del compilador diciendo que no es capaz de encontrar <CODE>"glibconfig.h"</CODE>.</A>
</H2>
<P>El archivo de encabezado "glibconfig.h" se movió al directorio
$exec_prefix/lib/glib/include/. $exec_prefix es el directorio que fue
especificado al dar la bandera --exec-prefix a ./configure cuando se
compiló GTK+. Va por omisión a $prefix, (especificado con --prefix),
que en su lugar va por omisión a /usr/local/.
<P>Ésto se hizo asi porque "glibconfig.h" incluye información
dependiente de la arquitectura, y el resto de los archivos <EM>include</EM>
se colocan en $prefix/include, el cual puede ser compartido entre distintas
arquitecturas.
<P>GTK+ incluye un guión para el intérprete de comandos,
<CODE>gtk-config</CODE>, el cual hace fácil
encontrar los caminos correctos de inclusión. El tutor de GTK+ incluye
un ejemplo de como utilizar <CODE>gtk-config</CODE> para una compilación simple
desde la línea de comandos. Para información sobre configuraciones más
complicadas, vea el archivo docs/gtk-config.txt en la distribución de GTK+.
<P>Si está intentando compilar un programa viejo, puede bordear el problema
al configurarlo con una línea de comando como:
<P>
<BLOCKQUOTE><CODE>
<PRE>
CPPFLAGS="-I/usr/local/include/glib/include" ./configure
</PRE>
</CODE></BLOCKQUOTE>
<P>para intérpretes de comandos compatibles con Bourne como bash, o para
variantes csh:
<P>
<BLOCKQUOTE><CODE>
<PRE>
setenv CPPFLAGS "-I/usr/local/include/glib/include"
./configure
</PRE>
</CODE></BLOCKQUOTE>
<P>(Sustituya el valor apropiado de $exec_prefix para /usr/local.)
<P>
<H2><A NAME="ss2.7">2.7 Cuando instalo El GIMP, configure reporta que no puede encontrar GTK.</A>
</H2>
<P>Hay varias razones comúnes para esto:
<UL>
<LI>Usted tiene una versión vieja de GTK instalada en algún lugar.
RedHat 5.0, por ejemplo, instala una copia anterior de GTK que no funcinará
con las últimas veriones de GIMP. Debe eliminar esta copia vieja, pero
observe que en el caso de RedHat 5.0 esto dañará las aplicaciones
<CODE>control-panel</CODE>.
<P>
</LI>
<LI><CODE>gtk-config</CODE> (u otro componente de GTK) no se encuentra en el camino
(<EM>path</EM>),
o hay una versión vieja en su sistema. Teclee:
<PRE>
gtk-config --version
</PRE>
para verificar ambos casos. Ésto debe devolver un valor de por lo menos
0.99.8 para que las cosas funcionen correctamente con GIMP 0.99.23. Si
devuelve un valor distinto a lo que usted espera, entonces tiene una versión
vieja de GTK en su sistema.
<P>
</LI>
<LI>El guión ./configure no puede encontrar las librerías GTK. Como
./configure compila varios programas de prueba, necesita poder encontrar las
librerías GTK. Revise la pregunta anterior para obtener más ayuda al
respecto.</LI>
</UL>
<P>Si nada de lo anterior ayuda, entonces revise config.log, el cual es
generado por ./configure cuando corre. Al final estará la última
acción tomada antes de fallar. Si es una sección de código fuente,
copie el código fuente a un archivo y compilelo con la línea
jústamente arriba de él en config.log. Si la compilación tiene
éxito, intente ejecutarlo.

<H2><A NAME="s3">3. Desarrollo de GTK+</A></H2>
<H2><A NAME="ss3.1">3.1 ¿Qué es esta cosa CVS de la cual todo el mundo habla, y cómo puedo acceder a ella?</A>
</H2>
<P>CVS es el Concurrent Version System (Sistema de Versión Concurrente) y es
un medio muy popular de control de versión para proyectos de software.
Está diseñado para permitir que múltiples autores puedan operar de
manera simultánea en el mismo árbol fuente. Este árbol fuente es
mantenido centralizadamente, pero cada desarrollador tiene una réplica local
de este repositorio en el cual hacen sus cambios.
<P>Los desarrolladores de GTK+ utilizan un repositorio CVS para almacenar la
copia maestra de la actual versión en desarrollo de GTK+. Como tal,
la gente que desea contribuír con parches a GTK+ deben generarlos para la
versión del CVS. La gente normal debe utilizar los paquetes liberados.
<P>El conjunto de herramientas CVS está disponible como paquetes RPM en los
sitios usuales de RedHat. La última versión está disponible en
<A HREF="http://download.cyclic.com/pub/">&lt;http://download.cyclic.com/pub/&gt;</A><P>Cualquiera puede bajar la última versión CVS de GTK+ utilizando
acceso anónimo con los siguientes pasos:
<UL>
<LI> En un descendiente del intérprete de comandos bourne (ej. bash)
teclee:
<PRE>
export CVSROOT=':pserver:anonymous@anoncvs.gimp.org:/debian/home/gnomecvs'
</PRE>
</LI>
<LI>Luego, la primera vez que el árbol fuente se retira, se necesita
un <EM>login</EM> cvs.
<PRE>
cvs login
</PRE>
Ésto hará que se le solicite una clave de acceso. No hay clave de
acceso para cvs.gimp.org, así que solo ingrese un retorno de carro.</LI>
<LI>Para conseguir el árbol y colocarlo en un subdirectorio de su
directorio de trabajo actual, emita el comando:
<PRE>
cvs -z3 get gtk+
</PRE>
Observe que con el árbol GTK+ 1.1, glib se ha movido a un módulo CVS
separado, de manera que si no tiene glib instalado necesitará conseguirlo
igualmente:
<PRE>
cvs -z3 get glib
</PRE>
</LI>
</UL>
<H2><A NAME="ss3.2">3.2 ¿Cómo puedo contribuír a GTK+?</A>
</H2>
<P>Es simple. Si algo no funciona en un programa como usted piensa que debería,
revise la documentación para asegurarse de que no ha pasado algo por alto.
Si es un verdadero error o característica perdida, rastréelo en el
fuente de GTK+, cámbielo, y entonces genere un parche en la forma de un
'diff de contexto'. Esto puede hacerse utilizando un comando como
<CODE>diff -ru &lt;oldfile&gt; &lt;newfile&gt;</CODE>. Entonces envíe el archivo
de parche a:
<PRE>
ftp://ftp.gtk.org/incoming
</PRE>
junto a un archivo README. ¡Asegúrese de seguir las convenciones de
asignación de nombres o su parche será borrado! Los archivos deben ser
de esta forma:
<PRE>
gtk-&lt;username>-&lt;date yymmdd-n>.patch.gz
gtk-&lt;username>-&lt;date yymmdd-n>.patch.README
</PRE>
La "n" en la fecha indica un número único (empezando de 0)
de parches que subió ese día. Debe ser 0, a menos que envíe más de
un parche en el mismo día.
<P>Example:
<PRE>
gtk-gale-982701-0.patch.gz
gtk-gale-982701-0.patch.README
</PRE>
Una vez que usted envía <EM>lo que sea</EM>, envíe el README a
ftp-admin@gtk.org
<P>
<H2><A NAME="ss3.3">3.3 ¿Cómo averiguo si mi parche fue aplicado, y si no, por qué no?</A>
</H2>
<P>Los parches enviados se mandarán a
<CODE>ftp://ftp.gtk.org/pub/gtk/patches</CODE>
donde uno del equipo de desarrollo de GTK+ los recogerá. Si son aplicados,
serán movidos a <CODE>/pub/gtk/patches/old</CODE>.
<P>Los parches que no son aplicados, por cualquier razón, se mandarán a
<CODE>/pub/gtk/patches/unapplied</CODE> o <CODE>/pub/gtk/patches/outdated</CODE>.
En este punto puede preguntar en la lista de correo <CODE>gtk-list</CODE> el porqué
su parche no fué aplicado. Hay muchas razones posibles por las cuales un
parche no se aplica, pasando desde que no se puede aplicar limpiamente, hasta
que no es correcto. No se rinda si no logró que su parche se aplicase a la
primera.

<H2><A NAME="ss3.4">3.4 ¿Cuál es la política sobre la incorporación de nuevos <EM>widgets</EM> en la librería?</A>

<H2><A NAME="ss4.3">4.3 ¿GTK+ es seguro ante múltiples hilos?</A>
</H2>
<P>Aunque GTK+, como la mayoría de los juegos de herramientas para X,
no es seguro ante múltiples hilos, esto no prohibe el desarrollo de
aplicaciones con múltiples hilos con GTK+.
<P>Rob Browning (rlb@cs.utexas.edu) describe técnicas de hilamiento
que pueden utilizarse con GTK+ (levemente modificado):
<P>Básicamente existen dos enfoques principales, el primero es sencillo,
y el segundo complicado. En el primero, simplemente hay que asegurarse
de que todas las interacciones de GTK+ (o X) se manejan por un, y solo un,
hilo. Cualquier otro hilo que desee dibujar algo tiene que notificarlo de
alguna manera al hilo "GTK+", y dejarlo que maneje el trabajo real.
<P>El segundo enfoque le permite llamar funciones de GTK+ (o X) desde cualquier
hilo, pero requiere sincronización cuidadosa. La idea básica es crear
una exclusión mutua de protección para X, de manera que nadie haga
llamadas X sin primero adquirir esta exclusión mutua.
<P>Observe que se trata de un pequeño esfuerzo, pero que le permitirá ser
potencialmente más eficiente que un GTK+ completamente seguro ante
múltiples hilos. Usted decide la granularidad del bloqueo de hilos.
También debe asegurarse que el hilo que llama a gtk_main mantiene la
cerradura cuando llama a gtk_main.
<P>Lo siguiente por lo que hay que preocuparse ya que se tenía agarrada
la exclusión mutua global cuando se entró a gtk_main, es que todos
los <EM>callbacks</EM> también la tendrán. Esto significa que el
<EM>callback</EM> debe soltarla si va a llamar a cualquier otro código
que pueda readquirirla. De otra manera obtendrá un bloqueo mortal.
También hay que tener agarrada la exclusión mutua cuando finalmente
regresa del <EM>callback</EM>.
<P>Para permitir a otros hilos, además del que llama a gtk_main, tener
acceso a la exclusión mutua, necesitamos registrar una función de
trabajo con GTK que nos permita liberar la exclusión mutua
periódicamente.
<P>¿Por qué GTK+ no puede ser seguro ante múltiples hilos de
manera nativa?
<P>Complejidad, sobrecarga, y mano de obra. La proporción de programas
con hilos es todavía razonablemente pequeña, y conseguir seguridad
ante hilos es muy difícil y le quita tiempo valioso al trabajo
principal de obtener una buena librería gráfica terminada. Sería
muy agradable que GTK+ fuera seguro ante hilos "al sacarlo de la caja",
pero no es práctico ahora mismo, y haría a GTK+ sustancialmente menos
eficiente si no se maneja cuidadosamente.
<P>De cualquier manera, no es una prioridad esencial ya que existen remedios
relativamente buenos.
<P>
<H2><A NAME="ss4.4">4.4 ¿Cómo puedo prevenir el redibujar y reacomodar tamaños mientras cambio múltiples <EM>widgets</EM>?</A>
</H2>
<P>
Utilize gtk_container_disable_resize y gtk_container_enable_resize alrededor
del código donde quiere cambiar varias cosas. Esto resultará en mayor
velocidad ya que prevendrá tener que darle el tamaño otra vez a la
jerarquía de <EM>widget</EM> por completo.
<P>

<H2><A NAME="ss4.7">4.7 ¿Acaso es posible desplegar un texto que se recorte para que quepa dentro del lugar que tenga asignado?</A>
</H2>
<P>El comportamiento de GTK+ (sin recorte) es una consecuencia de sus intentos
para conservar recursos de X. Los <EM>widgets</EM> etiqueta (entre otros) no
tienen su propia ventana X - simplemente dibujan su contenido en la ventana
de su padre. Aunque sería posible hacer que ocurran recortes al establecer
la máscara de recorte antes de dibujar el texto, esto podría causar una
penalización substancial en el rendimiento.
<P>Es posible que, a largo plazo, la mejor solución a tales problemas sea
simplemente cambiar gtk para que le de ventanas X a las etiquetas. Un remedio
a corto plazo es poner el <EM>widget</EM> de etiqueta dentro de otro
<EM>widget</EM> que sí obtiene su propia ventana - un candidato posible puede ser el <EM>widget</EM> <EM>viewport</EM>.

</H2>
<P>De: Peter Mattis
<P>La razón por la cuál los botones no mueven a su hijo abajo y a la derecha
cuando son presionados es porque no me parece que eso es lo que ocurre
visualmente. Mi visión de los botonos es que los miras de manera recta.
O sea, la interface de usuario tiende sobre un plano y tú estás sobre
él observándolo de manera recta. Cuando un botón es presionado se
mueve directamente lejos de tí. Para ser absolutamente correcto supongo
que el hijo debería encojerse un poquito. Pero no veo por qué el hijo
debería moverse abajo y a la izquierda. Recurda, el hijo se supone que
está pegado a la superficie del botón. No es bueno que luzca como si
el hijo se resbala sobre la superficie del botón.
<P>En una nota más práctica, ya implanté esto una vez y determiné
que no se veía bien y lo quité.

<P>Probablemente usted está haciendo todos los cambios dentro de una función

<H2><A NAME="s5">5. Acerca de gdk</A></H2>
<H2><A NAME="ss5.1">5.1 ¿Qué es gdk?</A>
</H2>
<P>gdk es básicamente una envoltura alrededor de las llamadas a funciones
Xlib. Si estás familiarizado con Xlib, muchas de las funciones en gdk
requerirán poco o ningún tiempo para acostumbrarse.
Todas las funciones están escritas para proporcionar una manera fácil de
acceder a las funciones Xlib en una manera un poco más intuitiva.
Adicionalmente, ya que gdk utiliza glib (vea abajo), será más portable
y seguro de utilizar en
múltiples plataformas.
<P>
<P>
<H2><A NAME="ss5.2">5.2 ¿Cómo utilizo la asignación de colores?</A>
</H2>
<P>Una de las cosas agradables de GDK es que está basado sobre Xlib; esto
también es un problema, especialmente en el área de administración
de colores. Si usted quiere utilizar color en su programa (dibujando un
rectángulo o algo por el estilo, su código debe lucir algo así:
<P>
<BLOCKQUOTE><CODE>
<PRE>
{
GdkColor *color;
int width, height;
GtkWidget *widget;
GdkGC *gc;
...
/* primero, cree un GC (contexto grafico) en el cual dibujar */
gc = gdk_gc_new(widget->window);
/* encuentre las dimensiones correctas para el rectangulo */
gdk_window_get_size(widget->window, &amp;width, &amp;height);
/* el color que queremos utilizar */
color = (GdkColor *)malloc(sizeof(GdkColor));
/* rojo, verde y azul son valores pasados, indicando el trio RGB
* del color que queremos dibujar. Note que los valores de los componentes
* RGB dentro de GdkColor son tomados de 0 a 65535, no de 0 a 255.
*/
color->red = red * (65535/255);
color->green = green * (65535/255);
color->blue = blue * (65535/255);
/* el valor de pixel indica el indice en el mapa de colores del color.
* simplemente es una combinacion de los valores RGB colocados anteriormente
*/
color->pixel = (gulong)(red*65536 + green*256 + blue);
/* Sin embargo, el valor de pixel es solo valido en dispositivos de 24-bit
* (color verdadero). Por lo tanto, esta llamada es requerida para que GDK
* y X puedan darnos el color mas cercano disponible en el mapa de colores
*/
gdk_color_alloc(gtk_widget_get_colormap(widget), color);
/* colocar la parte delantera a nuestro color */
gdk_gc_set_foreground(gc, color);
/* dibujar el rectangulo*/
gdk_draw_rectangle(widget->window, gc, 1, 0, 0, width, height);
...

<H2><A NAME="s6">6. Acerca de glib</A></H2>
<H2><A NAME="ss6.1">6.1 ¿Qué es glib?</A>
</H2>
<P>glib es una librería de funciones y definiciones útiles disponibles
para ser utilizadas cuando se crean aplicaciones GDK y GTK. Proporciona
reemplazos para algunas funciones estándar de libc, como malloc, las
cuales tienen errores en algunos sistemas.
<P>También proporciona rutinas para manejar:
<UL>
<LI>Listas Doblemente Enlazadas</LI>
<LI>Listas con Enlace Sencillo</LI>
<LI>Cronómetros</LI>
<LI>Manipulación de cadenas</LI>
<LI>Un Analizador Léxico</LI>
<LI>Funciones de Error</LI>
</UL>
<P>
<P>
<H2><A NAME="ss6.2">6.2 ¿Por qué utilizar g_print, g_malloc, g_strdup y funciones compañeras de glib?</A>
</H2>
<P>Gracias a Tim Janik que escribió a gtk-list: (ligeramente modificado)
<BLOCKQUOTE>
Con respecto a g_malloc(), g_free() y hermanos, estas funciones son más
seguras que sus equivalentes en libc. Por ejemplo, g_free() solo regresa si
se llama con NULL. También, si se define USE_DMALLOC, la definición para
estas funciones cambia (en glib.h) para utilizar MALLOC(), FREE() etc... Si
MEM_PROFILE o MEM_CHECK se definen, hay incluso pequeñas estadísticas
realizadas las cuales cuentan los tamaños de los bloques (mostrado por
g_mem_profile() / g_mem_check()).
<P>Considerando el hecho de que glib provee una interface para salvar espacio en
pedazos de memoria si se tiene varios bloques que son siempre del mismo
tamaño y para marcarlos ALLOC_ONLY si es necesario, es sencillo crear
una pequeña envoltura para salvar (revisable para errores) alrededor del
malloc/free normal asimismo - igual que gdk cubre Xlib. ;)
<P>Utilizar g_error() y g_warning() dentro de aplicaciones como GIMP las cuales
utilizan gtk por completo incluso da la oportunidad de hacer saltar una ventana
que muestre los mensajes dentro de una ventana gtk con tu propio handler
(utilizando g_set_error_handler()) con el mismo estilo que gtk_print()
(dentro de gtkmain.c).

This package contains the reference documentation
for GTK+. For more information about GTK+
see:
http://www.gtk.org
For information about contributing to the
GLib/GTK+ reference documentation project, see:
http://www.gtk.org/rdp/
The GTK+ reference documentation is freely redistributable,
see the file COPYING for details.
REQUIREMENTS
============
To build the documentation, you must have the gtk-doc
package installed. To rebuild the template files,
you must have the current version of the GTK+
header files installed.
BUILD
=====
First, run configure to generate the makefiles for this
module. There is one option specific to this package
--with-html-dir=DIR top of installed HTML documentation tree
The Makefiles in the gdk/ and gtk/ subdirs each define three targets:
templates:
Scan the headers and merge the results with the current
template files
sgml:
Generate SGML files using the DocBook DTD from
the template files
html:
Generate HTML from the SGML files.
To build the documentation, do:
make sgml
make html
You should only run the 'make templates' step if you
need to regenerate the templates for a more recent
version of the GTK+ sources.
INSTALLATION
============
make install

Before making any changes to this module, please
contact:
Damon Chaplin <damon@karuna.freeserve.co.uk>
This will ensure that duplicate work does not occur,
and also make sure we know who has written what
parts of the documentation. See
http://www.gtk.org/rdp/
for more information.
By contributing work to the Reference Documentation
Project, you agree that it will be covered under the
license terms described in the file COPYING
included in this directory.
Other notes:
- Do not run 'make templates' unless you have
the latest cvs version of the gtk-1-2
branch of GTK+ and the latest CVS version
of gtk-doc.
(This is very important. Otherwise, the template
files may be come corrupted.)
Make sure that gtk-config --prefix points
to the correct version of GTK+.
- As always, ChangeLog entries should be made for
each commit. These can be really brief
"documented GHashTable"; but if you are editing
something someone else wrote, please be specific.
(Or better, send the changes to them for their
approval, first)

<appendix id="compiling">
<title>Compiling the <application>gdk-pixbuf</application>
library</title>
<para>
This appendix describes the special options you can use while
compiling the <application>gdk-pixbuf</application> library.
</para>
<sect1 id="building">
<title>Building the Library</title>
<para>
The <application>gdk-pixbuf</application> library uses the
standard GNU build system, using
<application>autoconf</application> for package configuration
and resolving portability issues,
<application>automake</application> for building makefiles
that comply with the GNU Coding Standards, and
<application>libtool</application> for building shared
libraries on multiple platforms. The normal sequence for
compiling and installing the
<application>gdk-pixbuf</application> library is thus:
<literallayout>
<userinput>./configure</userinput>
<userinput>make</userinput>
<userinput>make install</userinput>
</literallayout>
</para>
<para>
The standard options provided by <application>GNU
autoconf</application> may be passed to the
<command>configure</command> script. Please see the
<application>autoconf</application> documentation or run
<command>./configure --help</command> for information about
the standard options.
</para>
</sect1>
<sect1 id="extra-configuration-options">
<title>Extra Configuration Options</title>
<para>
In addition to the normal options, the
<command>configure</command> script in the
<application>gdk-pixbuf</application> library supports these
additional arguments:
<cmdsynopsis>
<command>configure</command>
<group>
<arg>--disable-modules</arg>
<arg>--enable-modules</arg>
</group>
<group>
<arg>--disable-gtk-doc</arg>
<arg>--enable-gtk-doc</arg>
</group>
</cmdsynopsis>
</para>
<formalpara>
<title><systemitem>--disable-modules</systemitem> and
<systemitem>--enable-modules</systemitem></title>
<para>
Normally <application>gdk-pixbuf</application> will try to
build the image file format loaders as little shared
libraries that are loaded on demand. The
<systemitem>--disable-modules</systemitem> argument
indicates that they should all be built statically into the
<application>gdk-pixbuf</application> library instead. This
is useful for people who need to produce statically-linked
binaries. If neither
<systemitem>--disable-modules</systemitem> nor
<systemitem>--enable-modules</systemitem> is specified, then
the <command>configure</command> script will try to
auto-detect whether shared modules work on your system.
</para>
</formalpara>
<formalpara>
<title><systemitem>--disable-gtk-doc</systemitem> and
<systemitem>--enable-gtk-doc</systemitem></title>
<para>
By default the <command>configure</command> script will try
to auto-detect whether the
<application>gtk-doc</application> package is installed. If
it is, then it will use it to extract and build the
documentation for the <application>gdk-pixbuf</application>
library. These options can be used to explicitly control
whether gtk-doc should be used or not. If it is not used,
the distributed, pre-generated HTML files will be installed
instead of building them on your machine.

<!-- ##### SECTION Title ##### -->
Animations
<!-- ##### SECTION Short_Description ##### -->
Animations as multi-frame structures.
<!-- ##### SECTION Long_Description ##### -->
<para>
The <application>gdk-pixbuf</application> library provides a
simple mechanism to load and represent animations, primarily
animated GIF files. Animations are represented as lists of
#GdkPixbufFrame structures. Each frame structure contains a
#GdkPixbuf structure and information about the frame's overlay
mode and duration.
</para>
<!-- ##### SECTION See_Also ##### -->
<para>
#GdkPixbufLoader
</para>
<!-- ##### ENUM GdkPixbufFrameAction ##### -->
<para>
Each animation frame can have several things happen to it when the
next frame is displayed. The #GdkPixbufFrameAction determines
this. These are essentially the overlay modes supported by GIF
animations.
</para>
@GDK_PIXBUF_FRAME_RETAIN: The previous image should remain displayed,
and will potentially be occluded by the new frame.
@GDK_PIXBUF_FRAME_DISPOSE: The animation will be reverted to the state
before the frame was shown.
@GDK_PIXBUF_FRAME_REVERT: The animation will be reverted to the first
frame.
<!-- ##### STRUCT GdkPixbufFrame ##### -->
<para>
This structure describes a frame in a #GdkPixbufAnimation. Each
frame consists of a #GdkPixbuf, an offset of the frame within the
animation's bounding box, a duration, and an overlay mode or
action.
</para>
<!-- ##### STRUCT GdkPixbufAnimation ##### -->
<para>
This structure describes an animation, which is represented as a
list of #GdkPixbufFrame structures.

Image Data in Memory
<!-- ##### SECTION Short_Description ##### -->
Creating a pixbuf from image data that is already in memory.
<!-- ##### SECTION Long_Description ##### -->
<para>
The most basic way to create a pixbuf is to wrap an existing pixel
buffer with a #GdkPixbuf structure. You can use the
gdk_pixbuf_new_from_data() function to do this You need to specify
the destroy notification function that will be called when the
data buffer needs to be freed; this will happen when a #GdkPixbuf
is finalized by the reference counting functions If you have a
chunk of static data compiled into your application, you can pass
in #NULL as the destroy notification function so that the data
will not be freed.
</para>
<para>
The gdk_pixbuf_new() function can be used as a convenience to
create a pixbuf with an empty buffer. This is equivalent to
allocating a data buffer using malloc() and then wrapping it with
gdk_pixbuf_new_from_data(). The gdk_pixbuf_new() function will
compute an optimal rowstride so that rendering can be performed
with an efficient algorithm.
</para>
<para>
As a special case, you can use the gdk_pixbuf_new_from_xpm_data()
function to create a pixbuf from inline XPM image data.
</para>
<para>
You can also copy an existing pixbuf with the gdk_pixbuf_copy()
function. This is not the same as just doing a gdk_pixbuf_ref()
on the old pixbuf; the copy function will actually duplicate the
pixel data in memory and create a new #GdkPixbuf structure for it.

The <application>gdk-pixbuf</application> library provides a

<!-- ##### SECTION Title ##### -->
GdkPixbufLoader
<!-- ##### SECTION Short_Description ##### -->
Application-driven progressive image loading.
<!-- ##### SECTION Long_Description ##### -->
<para>
#GdkPixbufLoader provides a way for applications to drive the
process of loading an image, by letting them send the image data
directly to the loader instead of having the loader read the data
from a file. Applications can use this functionality instead of
gdk_pixbuf_new_from_file() when they need to parse image data in
small chunks. For example, it should be used when reading an
image from a (potentially) slow network connection, or when
loading an extremely large file.
</para>
<para>
To use #GdkPixbufLoader to load an image, just create a new one,
and call gdk_pixbuf_loader_write() to send the data to it. When
done, gdk_pixbuf_loader_close() should be called to end the stream
and finalize everything. The loader will emit two important
signals throughout the process. The first, "<link
linkend="GdkPixbufLoader-area-prepared">area_prepared</link>",
will be called as soon as the image has enough information to
determine the size of the image to be used. It will pass a
@GdkPixbuf in. If you want to use it, you can simply ref it. In
addition, no actual information will be passed in yet, so the
pixbuf can be safely filled with any temporary graphics (or an
initial color) as needed. You can also call the
gdk_pixbuf_loader_get_pixbuf() once this signal has been emitted
and get the same pixbuf.
</para>
<para>
The other signal, "<link
linkend="GdkPixbufLoader-area-updated">area_updated</link>" gets
called every time a region is updated. This way you can update a
partially completed image. Note that you do not know anything
about the completeness of an image from the area updated. For
example, in an interlaced image, you need to make several passes
before the image is done loading.
</para>
<refsect2>
<title>Loading an animation</title>
<para>
Loading an animation is a little more complex then loading an
image. In addition to the above signals, there is also a "<link
linkend="GdkPixbufLoader-frame-done">frame_done</link>" signal,
as well as an "<link
linkend="GdkPixbufLoader-animation-done">animation_done</link>"
signal. The first lets the application know that it is dealing
with an animation, instead of a static image. It also passes a
#GdkPixbufFrame in the signal. As before, if you want to keep
the frame, you need to ref it. Once the first "<link
linkend="GdkPixbufLoader-frame-done">frame_done</link>" signal
has been emitted, you can call gdk_pixbuf_loader_get_animation()
to get the #GdkPixbufAnimation struct. Each subsequent frame
goes through a similar lifecycle. For example "<link
linkend="GdkPixbufLoader-area-prepared">area_prepared</link>" is
re-emitted. Then "<link
linkend="GdkPixbufLoader-area-updated">area_updated</link>" is
emitted as many times as necessary. Finally, "<link
linkend="GdkPixbufLoader-animation-done">animation_done</link>"
is emitted as soon as all frames are done.

GnomeCanvasPixbuf
<!-- ##### SECTION Short_Description ##### -->
Canvas item to display #GdkPixbuf images.
<!-- ##### SECTION Long_Description ##### -->
<para>
This canvas item displays #GdkPixbuf images. It handles full
affine transformations in both GDK and antialiased modes, and also
supports the <ulink url="http://www.w3.org">W3C</ulink>'s <ulink
url="http://www.w3.org/Graphics/SVG/">SVG</ulink>-like scaling and
translation semantics for absolute pixel values.
</para>
<para>
#GdkPixbuf structures may be shared among different pixbuf canvas
items; the pixbuf item uses #GdkPixbuf's reference counting
functions for this.
</para>
<refsect2>
<title>Custom Scaling and Translation</title>
<para>
In addition to the normal affine transformations supported by
canvas items, the #GnomeCanvasPixbuf item supports independent
object arguments for scaling and translation. This is useful
for explicitly setting a size to which the pixbuf's image will
be scaled, and for specifying translation offsets that take
place in the item's local coordinate system.
</para>
<para>
By default, the pixbuf canvas item will attain the size in units
of the #GdkPixbuf it contains. If a #GnomeCanvasPixbuf is
configured to use a #GdkPixbuf that has a size of 300 by 200
pixels, then the pixbuf item will automatically obtain a size of
300 by 200 units in the item's local coordinate system. If the
item is transformed with a scaling transformation of (0.5, 2.0),
then the final image size will be of 150 by 400 pixels.
</para>
<para>
To set custom width and height values, you must set the <link
linkend="GnomeCanvasPixbuf--width-set">width_set</link> or <link
linkend="GnomeCanvasPixbuf--height-set">height_set</link>
arguments to %TRUE, and then set the <link
linkend="GnomeCanvasPixbuf--width">width</link> or <link
linkend="GnomeCanvasPixbuf--height">height</link> arguments to
the desired values. The former two arguments control whether
the latter two are used when computing the final image's size;
they are both %FALSE by default so that the pixbuf item will
attain a size in units equal to the size in pixels of the
#GdkPixbuf that the item contains.
</para>
<para>
The custom translation offsets are controlled by the <link
linkend="GnomeCanvasPixbuf--x">x</link> and <link
linkend="GnomeCanvasPixbuf--y">y</link> arguments. The logical
upper-left vertex of the image will be translated by the
specified distance, aligned with the item's local coordinate
system.
</para>
</refsect2>
<refsect2>
<title>Absolute Pixel Scaling and Translation</title>
<para>
The <ulink url="http://www.w3.org/Graphics/SVG/">Scalable Vector
Graphics</ulink> specification (SVG) of the <ulink
url="http://www.w3.org">World Wide Web Consortium</ulink> also
allows images to be translated and scaled by absolute pixel
values that are independent of an item's normal affine
transformation.
</para>
<para>
Normally, the pixbuf item's translation and scaling arguments
are interpreted in units, so they will be modified by the item's
affine transformation. The <link
linkend="GnomeCanvasPixbuf--width-in-pixels">width_in_pixels</link>,
<link
linkend="GnomeCanvasPixbuf--height-in-pixels">height_in_pixels</link>,
<link
linkend="GnomeCanvasPixbuf--x-in-pixels">x_in_pixels</link>, and
<link
linkend="GnomeCanvasPixbuf--y-in-pixels">y_in_pixels</link>
object arguments can be used to modify this behavior. If one of
these arguments is %TRUE, then the corresponding scaling or
translation value will not be affected lengthwise by the pixbuf
item's affine transformation.
</para>
<para>
For example, consider a pixbuf item whose size is (300, 200).
If the item is modified with a scaling transformation of (0.5,
2.0) but the <link
linkend="GnomeCanvasPixbuf--width-in-pixels">width_in_pixels</link>
is set to %TRUE, then the item will appear to be (300, 400)
pixels in size. This means that in this case the item's affine
transformation only applies to the height value, while the width
value is kept in absolute pixels.
</para>
<para>
Likewise, consider a pixbuf item whose (<link
linkend="GnomeCanvasPixbuf--x">x</link>, <link
linkend="GnomeCanvasPixbuf--y">y</link>) arguments are set to
(30, 40). If the item is then modified by the same scaling
transformation of (0.5, 2.0) but the <link
linkend="GnomeCanvasPixbuf--y-in-pixels">y_in_pixels</link>
argument is set to %TRUE, then the image's upper-left corner
will appear to be at position (15, 40). In this case, the
affine transformation is applied only to the x offset, while the
y offset is kept in absolute pixels.
</para>
<para>
In short, these arguments control whether a particular dimension
of a pixbuf item is scaled or not in the normal way by the
item's affine transformation.
</para>
</refsect2>
<refsect2>
<title>Resource Management</title>
<para>
When you set the #GdkPixbuf structure that a #GnomeCanvasPixbuf
item will use by setting the <link
linkend="GnomeCanvasPixbuf--pixbuf">pixbuf</link> argument, a
reference count will be added to that #GdkPixbuf structure.
When the pixbuf item no longer needs the #GdkPixbuf structure,
such as when the item is destroyed or when a new pixbuf
structure is passed to it, then the old #GdkPixbuf structure
will be automatically unreferenced.
</para>
<para>
This means that if an application just needs to load a pixbuf
image and set it into a pixbuf canvas item, it can do the
following to &lsquo;forget&rsquo; about the pixbuf structure:
<programlisting>
GdkPixbuf *pixbuf;
GnomeCanvasItem *item;
pixbuf = gdk_pixbuf_new_from_file ("foo.png");
g_assert (pixbuf != NULL);
item = gnome_canvas_item_new (gnome_canvas_root (my_canvas),
gnome_canvas_pixbuf_get_type (),
"pixbuf", pixbuf,
NULL);
gdk_pixbuf_unref (pixbuf);
</programlisting>
</para>
<para>
After this happens, the reference count of the pixbuf structure
will be 1: the gdk_pixbuf_new_from_file() function creates it
with a reference count of 1, then setting the <link
linkend="GnomeCanvasPixbuf--pixbuf">pixbuf</link> argument of
the #GnomeCanvasPixbuf item increases it to 2, and then it is
decremented to 1 by the call to gdk_pixbuf_unref(). When the
canvas item is destroyed, it will automatically unreference the
pixbuf structure again, causing its reference count to drop to
zero and thus be freed.

If this argument is %TRUE, then the width of the pixbuf will be

</para>
<!-- ##### ARG GnomeCanvasPixbuf:x_in_pixels ##### -->
<para>
If this argument is %TRUE, the pixbuf's translation with respect
to its logical origin in item-relative coordinates will be in
pixels, that is, the visible offset will not change even if the
item's affine transformation changes. If it is %FALSE, the
pixbuf's translation will be taken to be in canvas units, and thus
will change along with the item's affine transformation. The
default is %FALSE.

<!-- ##### SECTION Title ##### -->
Reference Counting and Memory Mangement
<!-- ##### SECTION Short_Description ##### -->
Functions to perform reference counting and memory management on a
#GdkPixbuf.
<!-- ##### SECTION Long_Description ##### -->
<para>
#GdkPixbuf structures are reference counted. This means that
an application can share a single pixbuf among many parts of the
code. When a piece of the program needs to keep a pointer to a
pixbuf, it should add a reference to it. When it no longer needs
the pixbuf, it should subtract a reference. The pixbuf will be
destroyed when its reference count drops to zero. Newly-created
#GdkPixbuf structures start with a reference count of one.
</para>
<para>
<emphasis>Finalizing</emphasis> a pixbuf means to free its pixel
data and to free the #GdkPixbuf structure itself. Most of the
library functions that create #GdkPixbuf structures create the
pixel data by themselves and define the way it should be freed;
you do not need to worry about those. The only function that lets
you specify how to free the pixel data is
gdk_pixbuf_new_from_data(). Since you pass it a pre-allocated
pixel buffer, you must also specify a way to free that data. This
is done with a function of type #GdkPixbufDestroyNotify. When a
pixbuf created with gdk_pixbuf_new_from_data() is finalized, your
destroy notification function will be called, and it is its
responsibility to free the pixel array.
</para>
<para>
As an extension to traditional reference counting, #GdkPixbuf
structures support defining a handler for the last unref
operation. If gdk_pixbuf_unref() is called on a #GdkPixbuf
structure that has a reference count of 1, i.e. its last
reference, then the pixbuf's last unref handler function will be
called. It is up to this function to determine whether to
finalize the pixbuf using gdk_pixbuf_finalize() or to just
continue execution. This can be used to implement a pixbuf cache
efficiently; please see the programmer's documentation for
details.

#GdkPixbuf, gdk_pixbuf_new_from_data().
</para>
<!-- ##### USER_FUNCTION GdkPixbufDestroyNotify ##### -->
<para>
A function of this type is responsible for freeing the pixel array
of a pixbuf. The gdk_pixbuf_new_from_data() function lets you
pass in a pre-allocated pixel array so that a pixbuf can be
created from it; in this case you will need to pass in a function
of #GdkPixbufDestroyNotify so that the pixel data can be freed
when the pixbuf is finalized.
</para>
@pixels: The pixel array of the pixbuf that is being finalized.
@data: User closure data.
<!-- ##### USER_FUNCTION GdkPixbufLastUnref ##### -->
<para>
A function of this type can be used to override the default
operation when a pixbuf loses its last reference, i.e. when
gdk_pixbuf_unref() is called on a #GdkPixbuf structure that has a
reference count of 1. This function should determine whether to
finalize the pixbuf by calling gdk_pixbuf_finalize(), or whether
to just resume normal execution. The last unref handler for a
#GdkPixbuf can be set using the
gdk_pixbuf_set_last_unref_handler() function. By default, pixbufs
will be finalized automatically if no last unref handler has been
defined.
</para>

Rendering
<!-- ##### SECTION Short_Description ##### -->
Rendering a pixbuf to a GDK drawable.
<!-- ##### SECTION Long_Description ##### -->
<para>
The <application>gdk-pixbuf</application> library provides several
convenience functions to render pixbufs to GDK drawables. It uses
the GdkRGB to render the image data.
</para>
<para>
At this point there is not a standard alpha channel extension for
the X Window System, so it is not possible to use full opacity
information when painting images to arbitrary drawables. The
<application>gdk-pixbuf</application> convenience functions will
threshold the opacity information to create a bi-level clipping
mask (black and white), and use that to draw the image onto a
drawable.
</para>
<important>
<para>
Since these functions use GdkRGB for rendering, you must
initialize GdkRGB before using any of them. You can do this by
calling gdk_rgb_init() near the beginning of your program.
</para>
</important>
<!-- ##### SECTION See_Also ##### -->
<para>
GdkRGB
</para>
<!-- ##### ENUM GdkPixbufAlphaMode ##### -->
<para>
These values can be passed to
gdk_pixbuf_render_to_drawable_alpha() to control how the alpha
chanel of an image should be handled. This function can create a
bilevel clipping mask (black and white) and use it while painting
the image. In the future, when the X Window System gets an alpha
channel extension, it will be possible to do full alpha
compositing onto arbitrary drawables. For now both cases fall
back to a bilevel clipping mask.
</para>
@GDK_PIXBUF_ALPHA_BILEVEL: A bilevel clipping mask (black and white)
will be created and used to draw the image. Pixels below 0.5 opacity
will be considered fully transparent, and all others will be
considered fully opaque.
@GDK_PIXBUF_ALPHA_FULL: For now falls back to #GDK_PIXBUF_ALPHA_BILEVEL.
In the future it will do full alpha compositing.

<!-- ##### SECTION Title ##### -->
Scaling
<!-- ##### SECTION Short_Description ##### -->
Scaling pixbufs and scaling and compositing pixbufs
<!-- ##### SECTION Long_Description ##### -->
<para>
The <application>gdk-pixbuf</application> contains functions to
scale pixbufs, to scale pixbufs and composite against an existing
image, and to scale pixbufs and composite against a solid color or
checkerboard. Compositing a checkerboard is a common way to show
an image with an alpha channel in image-viewing and editing
software.
</para>
<para>
Since the full-featured functions (gdk_pixbuf_scale(),
gdk_pixbuf_composite(), and gdk_pixbuf_composite_color()) are
rather complex to use and have many arguments, two simple
convenience functions are provided, gdk_pixbuf_scale_simple() and
gdk_pixbuf_composite_color_simple() which create a new pixbuf of a
given size, scale an original image to fit, and then return the
new pixmap.
</para>
<para>
The following example demonstrates handling an expose event by
rendering the appropriate area of a source image (which is scaled
to fit the widget) onto the widget's window. The source image is
rendered against a checkerboard, which provides a visual
representation of the alpha channel if the image has one. If the
image doesn't have an alpha channel, calling
gdk_pixbuf_composite_color() function has exactly the same effect
as calling gdk_pixbuf_scale().
</para>

GdkPixbuf *dest;
gdk_window_set_back_pixmap (widget->window, NULL, FALSE);

<!-- ##### ENUM GdkInterpType ##### -->
<para>
This enumeration describes the different interpolation modes that
can be used with the scaling functions.
<note>
<para>
Cubic filtering is missing from the list; hyperbolic
interpolation is just as fast and results in higher quality.
</para>
</note>
</para>
@GDK_INTERP_NEAREST: Nearest neighbor sampling; this is the fastest
and lowest quality mode.
@GDK_INTERP_TILES: This is an accurate simulation of the PostScript
image operator without any interpolation enabled. Each pixel is
rendered as a tiny parallelogram of solid color, the edges of which
are implemented with antialiasing. It resembles nearest neighbor for
enlargement, and bilinear for reduction.
@GDK_INTERP_BILINEAR: Bilinear interpolation. For enlargement, it is
equivalent to point-sampling the ideal bilinear-interpolated image.
For reduction, it is equivalent to laying down small tiles and
integrating over the coverage area.
@GDK_INTERP_HYPER: This is the slowest and highest quality
reconstruction function. It is derived from the hyperbolic filters in
Wolberg's "Digital Image Warping", and is formally defined as the
hyperbolic-filter sampling the ideal hyperbolic-filter interpolated
image (the filter is designed to be idempotent for 1:1 pixel mapping).

<!-- ##### SECTION Title ##### -->
Colormaps and Colors
<!-- ##### SECTION Short_Description ##### -->
manipulation of colors and colormaps.
<!-- ##### SECTION Long_Description ##### -->
<para>
These functions are used to modify colormaps.
A colormap is an object that contains the mapping
between the color values stored in memory and
the RGB values that are used to display color
values. In general, colormaps only contain
significant information for pseudo-color visuals,
but even for other visual types, a colormap object
is required in some circumstances.
</para>
<para>
There are a couple of special colormaps that can
be retrieved. The system colormap (retrieved
with gdk_colormap_get_system()) is the default
colormap of the system. If you are using GdkRGB,
there is another colormap that is important - the
colormap in which GdkRGB works, retrieved with
gdk_rgb_get_cmap(). However, when using GdkRGB,
it is not generally necessary to allocate colors
directly.
</para>
<para>
In previous revisions of this interface, a number
of functions that take a #GdkColormap parameter
were replaced with functions whose names began
with "gdk_colormap_". This process will probably
be extended somewhat in the future -
gdk_color_white(), gdk_color_black(), and
gdk_color_change() will probably become aliases.
</para>

<!-- ##### SECTION Title ##### -->
Drawing Primitives
<!-- ##### SECTION Short_Description ##### -->
functions for drawing points, lines, arcs, and text.
<!-- ##### SECTION Long_Description ##### -->
<para>
These functions provide support for drawing points, lines, arcs and text
onto what are called 'drawables'. Drawables, as the name suggests, are things
which support drawing onto them, and are either #GdkWindow or #GdkPixmap
objects.
</para>
<para>
Many of the drawing operations take a #GdkGC argument, which represents a
graphics context. This #GdkGC contains a number of drawing attributes such
as foreground color, background color and line width, and is used to reduce
the number of arguments needed for each drawing operation. See the
<link linkend="gdk-Graphics-Contexts">Graphics Contexts</link> section for
more information.
</para>
<!-- ##### SECTION See_Also ##### -->
<para>
</para>
<!-- ##### FUNCTION gdk_draw_point ##### -->
<para>
Draws a point, using the foreground color and other attributes of the #GdkGC.
</para>
@drawable: a #GdkDrawable (a #GdkWindow or a #GdkPixmap).
@gc: a #GdkGC.
@x: the x coordinate of the point.
@y: the y coordinate of the point.
<!-- ##### FUNCTION gdk_draw_points ##### -->
<para>
Draws a number of points, using the foreground color and other attributes of
the #GdkGC.
</para>
@drawable: a #GdkDrawable (a #GdkWindow or a #GdkPixmap).
@gc: a #GdkGC.
@points: an array of #GdkPoint structures.
@npoints: the number of points to be drawn.
<!-- ##### FUNCTION gdk_draw_line ##### -->
<para>
Draws a line, using the foreground color and other attributes of the #GdkGC.
</para>
@drawable: a #GdkDrawable (a #GdkWindow or a #GdkPixmap).
@gc: a #GdkGC.
@x1: the x coordinate of the start point.
@y1: the y coordinate of the start point.
@x2: the x coordinate of the end point.
@y2: the y coordinate of the end point.
<!-- ##### FUNCTION gdk_draw_lines ##### -->
<para>
Draws a series of lines connecting the given points.
The way in which joins between lines are draw is determined by the
#GdkCapStyle value in the #GdkGC. This can be set with
gdk_gc_set_line_attributes().
</para>
@drawable: a #GdkDrawable (a #GdkWindow or a #GdkPixmap).
@gc: a #GdkGC.
@points: an array of #GdkPoint structures specifying the endpoints of the
lines.
@npoints: the size of the @points array.
<!-- ##### FUNCTION gdk_draw_segments ##### -->
<para>
Draws a number of unconnected lines.
</para>
@drawable: a #GdkDrawable (a #GdkWindow or a #GdkPixmap).
@gc: a #GdkGC.
@segs: an array of #GdkSegment structures specifying the start and end points
of the lines to be drawn,
@nsegs: the number of line segments to draw, i.e. the size of the @segs array.
<!-- ##### STRUCT GdkSegment ##### -->
<para>
Specifies the start and end point of a line for use by the gdk_draw_segments()
function.
</para>
@x1: the x coordinate of the start point.
@y1: the y coordinate of the start point.
@x2: the x coordinate of the end point.
@y2: the y coordinate of the end point.
<!-- ##### FUNCTION gdk_draw_rectangle ##### -->
<para>
Draws a rectangular outline or filled rectangle, using the foreground color
and other attributes of the #GdkGC.
</para>
<note>
<para>
A rectangle drawn filled is 1 pixel smaller in both dimensions than a rectangle
outlined. Calling gdk_draw_rectangle (window, gc, TRUE, 0, 0, 20, 20) results
in a filled rectangle 20 pixels wide and 20 pixels high. Calling
gdk_draw_rectangle (window, gc, FALSE, 0, 0, 20, 20) results in an outlined
rectangle with corners at (0, 0), (0, 20), (20, 20), and (20, 0), which
makes it 21 pixels wide and 21 pixels high.
</para>
</note>

@gc: a #GdkGC.
@filled: TRUE if the rectangle should be filled.
@x: the x coordinate of the left edge of the rectangle.
@y: the y coordinate of the top edge of the rectangle.
@width: the width of the rectangle.

@angle1: the start angle of the arc, relative to the 3 o'clock position,
counter-clockwise, in 1/64ths of a degree.
@angle2: the end angle of the arc, relative to @angle1, in 1/64ths of a degree.
<!-- ##### FUNCTION gdk_draw_polygon ##### -->
<para>
Draws an outlined or filled polygon.
</para>
@drawable: a #GdkDrawable (a #GdkWindow or a #GdkPixmap).
@gc: a #GdkGC.
@filled: TRUE if the polygon should be filled. The polygon is closed
automatically, connecting the last point to the first point if necessary.
@points: an array of #GdkPoint structures specifying the points making up the
polygon.
@npoints: the number of points.

<!-- ##### SECTION Title ##### -->
Event Structures
<!-- ##### SECTION Short_Description ##### -->
data structures specific to each type of event.
<!-- ##### SECTION Long_Description ##### -->
<para>
The event structs contain data specific to each type of event in GDK.
</para>
<note>
<para>
A common mistake is to forget to set the event mask of a widget so that the
required events are received. See gtk_widget_set_events().
</para>
</note>
<!-- ##### SECTION See_Also ##### -->
<para>
</para>
<!-- ##### UNION GdkEvent ##### -->
<para>
The #GdkEvent struct contains a union of all of the event structs,
and allows access to the data fields in a number of ways.
</para>
<para>
The event type is always the first field in all of the event structs, and
can always be accessed with the following code, no matter what type of event
it is:
<informalexample>
<programlisting>
GdkEvent *event;
GdkEventType type;
type = event->type;
</programlisting>
</informalexample>
</para>
<para>
To access other fields of the event structs, the pointer to the event can be
cast to the appropriate event struct pointer, or the union member name can be
used. For example if the event type is %GDK_BUTTON_PRESS then the x coordinate
of the button press can be accessed with:
<informalexample>
<programlisting>
GdkEvent *event;
gdouble x;
x = ((GdkEventButton*)event)->x;
</programlisting>
</informalexample>
or:
<informalexample>
<programlisting>
GdkEvent *event;
gdouble x;
x = event->button.x;
</programlisting>
</informalexample>
</para>
<!-- ##### STRUCT GdkEventAny ##### -->
<para>
Contains the fields which are common to all event structs.
Any event pointer can safely be cast to a pointer to a #GdkEventAny to access
these fields.
</para>
@type: the type of the event.
@window: the window which received the event.
@send_event: TRUE if the event was sent explicitly (e.g. using XSendEvent).
<!-- ##### STRUCT GdkEventKey ##### -->
<para>
Describes a key press or key release event.
</para>
@type: the type of the event (%GDK_KEY_RELEASE or %GDK_KEY_RELEASE).
@window: the window which received the event.
@send_event: TRUE if the event was sent explicitly (e.g. using XSendEvent).
@time: the time of the event in milliseconds.
@state: a bit-mask representing the state of the modifier keys (e.g. Control,
Shift and Alt) and the pointer buttons. See #GdkModifierType.
@keyval: the key that was pressed or released. See the &lt;gdk/gdkkeysym.h&gt;
header file for a complete list of GDK key codes.
@length: the length of @string.
@string: a null-terminated multi-byte string containing the composed characters
resulting from the key press. When text is being input, in a GtkEntry for
example, it is these characters which should be added to the input buffer.
When using <link linkend="gdk-Input-Methods"> Input Methods</link> to support
internationalized text input, the composed characters appear here after the
pre-editing has been completed.
<!-- ##### STRUCT GdkEventButton ##### -->
<para>
Used for button press and button release events. The
<structfield>type</structfield> field will be one of %GDK_BUTTON_PRESS,
%GDK_2BUTTON_PRESS, %GDK_3BUTTON_PRESS, and %GDK_BUTTON_RELEASE.
</para>
<para>
Double and triple-clicks result in a sequence of events being received.
For double-clicks the order of events will be:
<orderedlist>
<listitem><para>%GDK_BUTTON_PRESS</para></listitem>
<listitem><para>%GDK_BUTTON_RELEASE</para></listitem>
<listitem><para>%GDK_BUTTON_PRESS</para></listitem>
<listitem><para>%GDK_2BUTTON_PRESS</para></listitem>
<listitem><para>%GDK_BUTTON_RELEASE</para></listitem>
</orderedlist>
Note that the first click is received just like a normal
button press, while the second click results in a %GDK_2BUTTON_PRESS being
received just after the %GDK_BUTTON_PRESS.
</para>
<para>
Triple-clicks are very similar to double-clicks, except that %GDK_3BUTTON_PRESS
is inserted after the third click. The order of the events is:
<orderedlist>
<listitem><para>%GDK_BUTTON_PRESS</para></listitem>
<listitem><para>%GDK_BUTTON_RELEASE</para></listitem>
<listitem><para>%GDK_BUTTON_PRESS</para></listitem>

<listitem><para>%GDK_3BUTTON_PRESS</para></listitem>
<listitem><para>%GDK_BUTTON_RELEASE</para></listitem>
</orderedlist>
</para>
<para>
For a double click to occur, the second button press must occur within 1/4 of
a second of the first. For a triple click to occur, the third button press
must also occur within 1/2 second of the first button press.
</para>
@type: the type of the event (%GDK_BUTTON_PRESS, %GDK_2BUTTON_PRESS,
%GDK_3BUTTON_PRESS or %GDK_BUTTON_RELEASE).

@button: the button which was pressed or released, numbered from 1 to 5.
Normally button 1 is the left mouse button, 2 is the middle button,
and 3 is the right button. On 2-button mice, the middle button can often
be simulated by pressing both mouse buttons together.
@source: the input device where the event came from, usually %GDK_SOURCE_MOUSE.

Specifies the type of the event.
</para>
<para>
Do not confuse these events with the signals that GTK+ widgets emit.
Although many of these events result in corresponding signals being emitted,
the events are often transformed or filtered along the way.
</para>
@GDK_NOTHING: a special code to indicate a null event.
@GDK_DELETE: the window manager has requested that the toplevel window be
hidden or destroyed, usually when the user clicks on a special icon in the
title bar.
@GDK_DESTROY: the window has been destroyed.
@GDK_EXPOSE: all or part of the window has become visible and needs to be
redrawn.
@GDK_MOTION_NOTIFY: the pointer (usually a mouse) has moved.
@GDK_BUTTON_PRESS: a mouse button has been pressed.
@GDK_2BUTTON_PRESS: a mouse button has been double-clicked (clicked twice
within a short period of time). Note that each click also generates a
%GDK_BUTTON_PRESS event.
@GDK_3BUTTON_PRESS: a mouse button has been clicked 3 times in a short period
of time. Note that each click also generates a %GDK_BUTTON_PRESS event.
@GDK_BUTTON_RELEASE: a mouse button has been released.
@GDK_KEY_PRESS: a key has been pressed.
@GDK_KEY_RELEASE: a key has been released.
@GDK_ENTER_NOTIFY: the pointer has entered the window.
@GDK_LEAVE_NOTIFY: the pointer has left the window.
@GDK_FOCUS_CHANGE: the keyboard focus has entered or left the window.
@GDK_CONFIGURE: the size, position or stacking order of the window has changed.
Note that GTK+ discards these events for %GDK_WINDOW_CHILD windows.
@GDK_MAP: the window has been mapped.
@GDK_UNMAP: the window has been unmapped.
@GDK_PROPERTY_NOTIFY: a property on the window has been changed or deleted.
@GDK_SELECTION_CLEAR: the application has lost ownership of a selection.
@GDK_SELECTION_REQUEST: another application has requested a selection.
@GDK_SELECTION_NOTIFY: a selection has been received.
@GDK_PROXIMITY_IN: an input device has moved into contact with a sensing
surface (e.g. a touchscreen or graphics tablet).
@GDK_PROXIMITY_OUT: an input device has moved out of contact with a sensing
surface.
@GDK_DRAG_ENTER: the mouse has entered the window while a drag is in progress.
@GDK_DRAG_LEAVE: the mouse has left the window while a drag is in progress.
@GDK_DRAG_MOTION: the mouse has moved in the window while a drag is in
progress.
@GDK_DRAG_STATUS: the status of the drag operation initiated by the window
has changed.
@GDK_DROP_START: a drop operation onto the window has started.
@GDK_DROP_FINISHED: the drop operation initiated by the window has completed.
@GDK_CLIENT_EVENT: a message has been received from another application.
@GDK_VISIBILITY_NOTIFY: the window visibility status has changed.
@GDK_NO_EXPOSE: indicates that the source region was completely available
when parts of a drawable were copied. This is not very useful.
<!-- ##### ENUM GdkEventMask ##### -->
<para>
A set of bit-flags to indicate which events a window is to receive.

</para>
<para>
%GDK_POINTER_MOTION_HINT_MASK is a special mask which is used to reduce the
number of %GDK_MOTION_NOTIFY events received. Normally a %GDK_MOTION_NOTIFY
event is received each time the mouse moves. However, if the application
spends a lot of time processing the event (updating the display, for example),
it can easily lag behind the position of the mouse. When using the
%GDK_POINTER_MOTION_HINT_MASK the server will only send %GDK_MOTION_NOTIFY
events when the application asks for them, by calling gdk_window_get_pointer().

The GdkFont data type represents a font for drawing on
the screen. These functions provide support for
loading fonts, and also for determining the dimensions
of characters and strings when drawn with a particular
font.
</para>
<para>
Fonts in X are specified by a
<firstterm>X Logical Font Description</firstterm>.
The following description is considerably simplified.
For definitive information about XLFD's see the
X reference documentation. A X Logical Font Description (XLFD)
consists of a sequence of fields separated (and surrounded by) '-'
characters. For example, Adobe Helvetica Bold 12 pt, has the
full description:
<programlisting>
"-adobe-helvetica-bold-r-normal--12-120-75-75-p-70-iso8859-1"
</programlisting>
</para>

<para>
When specifying a font via a X logical Font Description,
'*' can be used as a wildcard to match any portion of
the XLFD. For instance, the above example could
also be specified as
<programlisting>
"-*-helvetica-bold-r-normal--*-120-*-*-*-*-iso8859-1"
</programlisting>
It is generally a good idea to use wildcards for any
portion of the XLFD that your program does not care
about specifically, since that will improve the
chances of finding a matching font.
</para>
<para>
A <firstterm>fontset</firstterm> is a list of fonts
that is used for drawing international text that may
contain characters from a number of different character
sets. It is represented by a list of XLFD's.
</para>
<para>
The font for a given character set is determined by going
through the list of XLFD's in order. For each one, if
the registry and and encoding fields match the desired
character set, then that font is used, otherwise if
the XLFD contains wild-cards for the registry and encoding
fields, the registry and encoding for the desired character
set are subsituted in and a lookup is done. If a match is found
that font is used. Otherwise, processing continues
on to the next font in the list.
</para>
<para>
The functions for determining the metrics of a string
come in several varieties that can take a number
of forms of string input:
<variablelist>
<varlistentry>
<term>8-bit string</term>
<listitem><para>
When using functions like gdk_string_width() that
take a <type>gchar *</type>, if the font is of type
%GDK_FONT_FONT and is an 8-bit font, then each
<type>gchar</type> indexes the glyphs in the font directly.
</para></listitem>
</varlistentry>
<varlistentry>
<term>16-bit string</term>
<listitem><para>
For functions taking a <type>gchar *</type>, if the
font is of type %GDK_FONT_FONT, and is a 16-bit
font, then the <type>gchar *</type> argument is
interpreted as a <type>guint16 *</type> cast to
a <type>gchar *</type> and each <type>guint16</type>
indexes the glyphs in the font directly.
</para></listitem>
</varlistentry>
<varlistentry>
<term>Multibyte string</term>
<listitem><para>
For functions taking a <type>gchar *</type>, if the
font is of type %GDK_FONT_FONTSET, then the input
string is interpreted as a <firstterm>multibyte</firstterm>
encoded according to the current locale. (A multibyte
string is one in which each character may consist
of one or more bytes, with different lengths for different
characters in the string). They can be converted to and
from wide character strings (see below) using
gdk_wcstombs() and gdk_mbstowcs().) The string will
be rendered using one or more different fonts from
the fontset.
</para></listitem>
</varlistentry>
<varlistentry>
<term>Wide character string</term>
<listitem><para>
For a number of the text-measuring functions, GTK+
provides a variant (such as gdk_text_width_wc()) which
takes a <type>GdkWChar *</type> instead of a
<type>gchar *</type>. The input is then taken to
be a wide character string in the encoding of the
current locale. (A wide character string is a string
in which each character consists of several bytes,
and the width of each character in the string is
constant.)

<!-- ##### TYPEDEF GdkWChar ##### -->
<para>
Specifies a wide character type, used to represent character codes.
This is needed since some native languages have character sets which have
more than 256 characters (Japanese and Chinese, for example).
</para>
<para>
Wide character values between 0 and 127 are always identical in meaning to
the ASCII character codes. The wide character value 0 is often used to
terminate strings of wide characters in a similar way to normal strings
using the char type.
</para>
<para>
An alternative to wide characters is multi-byte characters, which extend
normal char strings to cope with larger character sets. As the name suggests,
multi-byte characters use a different number of bytes to store different
character codes. For example codes 0-127 (i.e. the ASCII codes) often
use just one byte of memory, while other codes may use 2, 3 or even 4 bytes.
Multi-byte characters have the advantage that they can often be used in an
application with little change, since strings are still represented as arrays
of char values. However multi-byte strings are much easier to manipulate since
the character are all of the same size.
</para>
<para>
Applications typically use wide characters to represent character codes
internally, and multi-byte strings when saving the characters to a file.
The gdk_wcstombs() and gdk_mbstowcs() functions can be used to convert from
one representation to the other.
</para>
<para>
See the 'Extended Characters' section of the GNU C Library Reference Manual
for more detailed information on wide and multi-byte characters.
</para>
<!-- ##### FUNCTION gdk_wcstombs ##### -->
<para>
Converts a wide character string to a multi-byte string.
(The function name comes from an acronym of 'Wide Character String TO
Multi-Byte String').
</para>
@src: a wide character string.
@Returns: the multi-byte string corresponding to @src, or NULL if the
conversion failed. The returned string should be freed with g_free() when no
longer needed.
<!-- ##### FUNCTION gdk_mbstowcs ##### -->
<para>
Converts a multi-byte string to a wide character string.
(The function name comes from an acronym of 'Multi-Byte String TO Wide
Character String').
</para>
@dest: the space to place the converted wide character string into.
@src: the multi-byte string to convert, which must be null-terminated.
@dest_max: the maximum number of wide characters to place in @dest.
@Returns: the number of wide characters written into @dest, or -1 if the
conversion failed.

<para>
All drawing operations in GDK take a
<firstterm>graphics context</firstterm> (GC) argument.
A graphics context encapsulates information about
the way things are drawn, such as the foreground
color or line width. By using graphics contexts,
the number of arguments to each drawing call is
greatly reduced, and communication overhead is
minimized, since identical arguments do not need
to be passed repeatedly.
</para>
<para>
Most values of a graphics context can be set at
creation time by using gdk_gc_new_with_values(),
or can be set one-by-one using functions such
as gdk_gc_set_foreground(). A few of the values
in the GC, such as the dash pattern, can only

<!-- ##### FUNCTION gdk_init ##### -->
<para>
Initializes the GDK library and connects to the X server.
If initialization fails, a warning message is output and the application
terminates with a call to exit(1).
</para>

Any arguments used by GDK are removed from the array and @argc and @argv are
updated accordingly.

by GTK+ applications.
</para>
@argc: the number of command line arguments.

</para>
@argc: the number of command line arguments.
@argv: the array of command line arguments.
@Returns: TRUE if initialization succeeded.
<!-- ##### FUNCTION gdk_exit ##### -->
<para>
Exits the application using the exit() system call.
</para>
<para>
This routine is provided mainly for backwards compatability, since it used to
perform tasks necessary to exit the application cleanly. Those tasks are now
performed in a function which is automatically called on exit (via the use
of g_atexit()).
</para>
@error_code: the error code to pass to the exit() call.
<!-- ##### FUNCTION gdk_set_locale ##### -->
<para>
Initializes the support for internationalization by calling the setlocale()
system call. This function is called by gtk_set_locale() and so GTK+
applications should use that instead.
</para>
<para>
The locale to use is determined by the LANG environment variable,
so to run an application in a certain locale you can do something like this:
<informalexample>
<programlisting>
export LANG="fr"
... run application ...
</programlisting>
</informalexample>
</para>
<para>
If the locale is not supported by X then it is reset to the standard "C"
locale.
</para>
@Returns: the resulting locale.
<!-- ##### FUNCTION gdk_set_sm_client_id ##### -->
<para>
Sets the SM_CLIENT_ID property on the application's leader window so that
the window manager can save the application's state using the X11R6 ICCCM
session management protocol.
</para>
<para>
The leader window is automatically created by GDK and never shown. It's only
use is for session management. The WM_CLIENT_LEADER property is automatically
set on all X windows created by the application to point to the leader window.
</para>
<para>
See the X Session Management Library documentation for more information on
session management and the Inter-Client Communication Conventions Manual
(ICCCM) for information on the WM_CLIENT_LEADER property. (Both documents are
part of the X Windows distribution.)
</para>
@sm_client_id: the client id assigned by the session manager when the
connection was opened, or NULL to remove the property.
<!-- ##### FUNCTION gdk_get_display ##### -->
<para>
Gets the name of the display, which usually comes from the DISPLAY
environment variable or the --display command line option.
</para>
@Returns: the name of the display.
<!-- ##### FUNCTION gdk_flush ##### -->
<para>
Flushes the X output buffer and waits until all requests have been processed
by the server. This is rarely needed by applications. It's main use is for
trapping X errors with gdk_error_trap_push() and gdk_error_trap_pop().
</para>
<!-- ##### FUNCTION gdk_screen_width ##### -->
<para>
Returns the width of the screen in pixels.
</para>
@Returns: the width of the screen in pixels.
<!-- ##### FUNCTION gdk_screen_height ##### -->
<para>
Returns the height of the screen in pixels.
</para>
@Returns: the height of the screen in pixels.
<!-- ##### FUNCTION gdk_screen_width_mm ##### -->
<para>
Returns the width of the screen in millimeters.
Note that on many X servers this value will not be correct.
</para>
@Returns: the width of the screen in millimeters, though it is not always
correct.
<!-- ##### FUNCTION gdk_screen_height_mm ##### -->
<para>
Returns the height of the screen in millimeters.
Note that on many X servers this value will not be correct.
</para>
@Returns: the height of the screen in millimeters, though it is not always
correct.
<!-- ##### FUNCTION gdk_pointer_grab ##### -->
<para>
Grabs the pointer (usually a mouse) so that all events are passed to this
application until the pointer is ungrabbed with gdk_pointer_ungrab(), or
the grab window becomes unviewable.
This overrides any previous pointer grab by this client.
</para>
<para>
Pointer grabs are used for operations which need complete control over mouse
events, even if the mouse leaves the application.
For example in GTK+ it is used for Drag and Drop, for dragging the handle in
the #GtkHPaned and #GtkVPaned widgets, and for resizing columns in #GtkCList
widgets.
</para>
<para>
Note that if the event mask of an X window has selected both button press and
button release events, then a button press event will cause an automatic
pointer grab until the button is released.
X does this automatically since most applications expect to receive button
press and release events in pairs.
It is equivalent to a pointer grab on the window with @owner_events set to
TRUE.
</para>
@window: the #GdkWindow which will own the grab (the grab window).
@owner_events: if FALSE then all pointer events are reported with respect to
@window and are only reported if selected by @event_mask. If TRUE then pointer
events for this application are reported as normal, but pointer events outside
this application are reported with respect to @window and only if selected by
@event_mask. In either mode, unreported events are discarded.
@event_mask: specifies the event mask, which is used in accordance with
@owner_events.
@confine_to: TRUE to confine the pointer to @window. If the pointer is outside
@window, it will automatically be moved to the closest edge of @window and
enter and leave events will be generated as necessary.
@cursor: the cursor to display while the grab is active. If this is NULL then
the normal cursors are used for @window and its descendants, and the cursor
for @window is used for all other windows.
@time: the timestamp of the event which led to this pointer grab. This usually
comes from a #GdkEventButton struct, though #GDK_CURRENT_TIME can be used if
the time isn't known.
@Returns: 0 if the grab was successful.
<!-- ##### FUNCTION gdk_pointer_ungrab ##### -->
<para>
Ungrabs the pointer, if it is grabbed by this application.
</para>
@time: a timestamp from a #GdkEvent, or #GDK_CURRENT_TIME if no timestamp is
available.
<!-- ##### FUNCTION gdk_pointer_is_grabbed ##### -->
<para>
Returns TRUE if the pointer is currently grabbed by this application.
</para>
<para>
Note that the return value is not completely reliable since the X server may
automatically ungrab the pointer, without informing the application, if the
grab window becomes unviewable. It also does not take passive pointer grabs
into account.
</para>
@Returns: TRUE if the pointer is currently grabbed by this application.
Though this value is not always correct.
<!-- ##### FUNCTION gdk_keyboard_grab ##### -->
<para>
Grabs the keyboard so that all events are passed to this
application until the keyboard is ungrabbed with gdk_keyboard_ungrab().
This overrides any previous keyboard grab by this client.
</para>
@window: the #GdkWindow which will own the grab (the grab window).
@owner_events: if FALSE then all keyboard events are reported with respect to
@window. If TRUE then keyboard events for this application are reported as
normal, but keyboard events outside this application are reported with respect
to @window. Both key press and key release events are always reported,
independant of the event mask set by the application.
@time: a timestamp from a #GdkEvent, or #GDK_CURRENT_TIME if no timestamp is
available.
@Returns: 0 if the grab was successful.
<!-- ##### FUNCTION gdk_keyboard_ungrab ##### -->
<para>
Ungrabs the keyboard, if it is grabbed by this application.
</para>
@time: a timestamp from a #GdkEvent, or #GDK_CURRENT_TIME if no timestamp is
available.
<!-- ##### FUNCTION gdk_key_repeat_disable ##### -->
<para>
Disables the keyboard auto-repeat mode.
This should be used with care as it may affect other applications.
</para>
<!-- ##### FUNCTION gdk_key_repeat_restore ##### -->
<para>
Restores the keyboard auto-repeat mode to its state when the application was
started.
</para>
<!-- ##### FUNCTION gdk_beep ##### -->
<para>
Emits a short beep.
</para>
<!-- ##### FUNCTION gdk_get_use_xshm ##### -->
<para>
Returns TRUE if GDK will attempt to use the MIT-SHM shared memory extension.
</para>
<para>
The shared memory extension is used for #GdkImage, and consequently for
<link linkend="gdk-GdkRGB">GdkRGB</link>.
It enables much faster drawing by communicating with the X server through
SYSV shared memory calls. However, it can only be used if the X client and
server are on the same machine and the server supports it.
</para>
@Returns: TRUE if use of the MIT shared memory extension will be attempted.
<!-- ##### FUNCTION gdk_set_use_xshm ##### -->
<para>
Sets whether the use of the MIT shared memory extension should be attempted.
This function is mainly for internal use. It is only safe for an application
to set this to FALSE, since if it is set to TRUE and the server does not
support the extension it may cause warning messages to be output.
</para>
@use_xshm: TRUE if use of the MIT shared memory extension should be attempted.
<!-- ##### FUNCTION gdk_error_trap_push ##### -->
<para>
This function allows X errors to be trapped instead of the normal behavior
of exiting the application. It should only be used if it is not possible to
avoid the X error in any other way.
</para>
<example>
<title>Trapping an X error.</title>
<programlisting>
gdk_error_trap_push ();
/* ... Call the X function which may cause an error here ... */
/* Flush the X queue to catch errors now. */
gdk_flush ();
if (gdk_error_trap_pop ())
{
/* ... Handle the error here ... */
}
</programlisting>
</example>
<!-- ##### FUNCTION gdk_error_trap_pop ##### -->
<para>
Removes the X error trap installed with gdk_error_trap_push().
</para>
@Returns: the X error code, or 0 if no error occurred.

it will try creating a %GDK_IMAGE_SHARED image first and if that fails it will
then use %GDK_IMAGE_NORMAL.

the image data between client and server. However this will only be available
if client and server are on the same machine and the shared memory extension
is supported by the server.

<!-- ##### SECTION Title ##### -->
Input Devices
<!-- ##### SECTION Short_Description ##### -->
Functions for handling extended input devices.
<!-- ##### SECTION Long_Description ##### -->
<para>
In addition to the normal keyboard and mouse input devices, GTK+ also
contains support for <firstterm>extended input devices</firstterm>. In
particular, this support is targeted at graphics tablets. Graphics
tablets typically return sub-pixel positioning information and possibly
information about the pressure and tilt of the stylus. Under
X, the support for extended devices is done through the
<firstterm>XInput</firstterm> extension.
</para>
<para>
Because handling extended input devices may involve considerable
overhead, they need to be turned on for each #GdkWindow
individually using gdk_input_set_extension_events().
(Or, more typically, for GtkWidgets, using gtk_widget_set_extension_events()).
As an additional complication, depending on the support from
the windowing system, its possible that a normal mouse
cursor will not be displayed for a particular extension
device. If an application does not want to deal with displaying
a cursor itself, it can ask only to get extension events
from devices that will display a cursor, by passing the
%GDK_EXTENSION_EVENTS_CURSOR value to
gdk_input_set_extension_events(). Otherwise, the application
must retrieve the device information using gdk_input_list_devices(),
check the <structfield>has_cursor</structfield> field, and,
if it is %FALSE, draw a cursor itself when it receives
motion events.
</para>
<para>
Each pointing device is assigned a unique integer ID; events from a
particular device can be identified by the
<structfield>deviceid</structfield> field in the event structure. The
events generated by pointer devices have also been extended to contain
<structfield>pressure</structfield>, <structfield>xtilt</structfield>
and <structfield>ytilt</structfield> fields which contain the extended
information reported as additional <firstterm>valuators</firstterm>
from the device. The <structfield>pressure</structfield> field is a
a double value ranging from 0.0 to 1.0, while the tilt fields are
double values ranging from -1.0 to 1.0. (With -1.0 representing the
maximum title to the left or up, and 1.0 representing the maximum
tilt to the right or down.)
</para>
<para>
One additional field in each event is the
<structfield>source</structfield> field, which contains an
enumeration value describing the type of device; this currently
can be one of
%GDK_SOURCE_MOUSE,
%GDK_SOURCE_PEN,
%GDK_SOURCE_ERASER,
or %GDK_SOURCE_CURSOR. This field is present to allow simple
applications to (for instance) delete when they detect eraser
devices without having to keep track of complicated per-device
settings.
</para>
<para>
Various aspects of each device may be configured. The easiest way of
creating a GUI to allow the user to conifigure such a device
is to use to use the #GtkInputDialog widget in GTK+.
However, even when using this widget, application writers
will need to directly query and set the configuration parameters
in order to save the state between invocations of the application.
The configuration of devices is queried using gdk_input_list_devices.
Each device must is activated using gdk_input_set_mode(), which
also controls whether the device's range is mapped to the
entire screen or to a single window. The mapping of the valuators of
the device onto the predefined valuator types is set using
gdk_input_set_axes. And the source type for each device
can be set with gdk_input_set_source().
</para>
<para>
Devices may also have associated <firstterm>keys</firstterm>
or macro buttons. Such keys can be globally set to map
into normal X keyboard events. The mapping is set using
gdk_input_set_key().
</para>
<para>
The interfaces in this section will most likely be considerably
modified in the future to accomodate devices that may have different
sets of additional valuators than the pressure xtilt and ytilt.

<!-- ##### ENUM GdkIMStyle ##### -->
<para>
A set of bit-flags used to specify the input method styles which are supported
or which are currently in use. The flags can be divided into 2 groups, the
pre-edit flags and the status flags.
</para>
<para>
The pre-edit flags specify how pre-editing data is displayed.
For example, this could display the text being typed in the phonetic
alphabet before it is composed and inserted as an ideograph.
</para>
<para>
The status flags specify how status information is displayed.
The status information can be thought of as an extension of the
standard keyboard mode indicators, such as the Caps Lock indicator.
</para>
<note>
<para>
The %GDK_IM_PREEDIT_CALLBACKS and %GDK_IM_STATUS_CALLBACKS styles are not
currently supported in GTK+.
</para>
</note>
@GDK_IM_PREEDIT_AREA: The application provides the input method with an area
in which to perform <emphasis>off-the-spot</emphasis> pre-editing.
@GDK_IM_PREEDIT_CALLBACKS: The application registers a number of callback
functions which are used to display pre-editing data.
@GDK_IM_PREEDIT_POSITION: The application provides the input method with the
position of the insertion cursor, for <emphasis>over-the-spot</emphasis>
pre-editing. The input method creates its own window over the widget to
display the pre-editing data.
@GDK_IM_PREEDIT_NOTHING: The input method uses the root X window to perform
pre-editing, so the application does not need to do anything.
@GDK_IM_PREEDIT_NONE: No pre-editing is done by the input method, or no
pre-editing data needs to be displayed.
@GDK_IM_PREEDIT_MASK: A bit-mask containing all the pre-edit flags.
@GDK_IM_STATUS_AREA: The application provides the input method with an area
in which to display status information.
@GDK_IM_STATUS_CALLBACKS: The applications registers a number of callback
functions which are used to display status information.
@GDK_IM_STATUS_NOTHING: The input method uses the root X window to display
status information, so the application does not need to do anything.
@GDK_IM_STATUS_NONE: The input method does not display status information.
@GDK_IM_STATUS_MASK: A bit-mask containing all the status flags.
<!-- ##### FUNCTION gdk_im_ready ##### -->
<para>
Checks if an input method is to be used for the current locale.
If GTK+ has been compiled without support for input methods, or the current
locale doesn't need an input method, then this will return FALSE.
</para>
@Returns: TRUE if an input method is available and should be used.
<!-- ##### FUNCTION gdk_im_decide_style ##### -->
<para>
Decides which input method style should be used, by comparing the styles given
in @supported_style with those of the available input method.
</para>
@supported_style: styles which are supported by the widget.
@Returns: the best style in @supported_style that is also supported by the
available input method.
<!-- ##### FUNCTION gdk_im_set_best_style ##### -->
<para>
Sets the best pre-edit and/or status style which should be used.
This will affect the style chosen in gdk_im_decide_style().
</para>
<para>
The order of the pre-edit styles is (from worst to best):
%GDK_IM_PREEDIT_NONE, %GDK_IM_PREEDIT_NOTHING, %GDK_IM_PREEDIT_AREA,
%GDK_IM_PREEDIT_POSITION, %GDK_IM_PREEDIT_CALLBACKS.
The order of the status styles is:
%GDK_IM_STATUS_NONE, %GDK_IM_STATUS_NOTHING, %GDK_IM_STATUS_AREA,
%GDK_IM_STATUS_CALLBACKS.
</para>
<para>
So, for example, to set the best allowed pre-edit style to %GDK_IM_PREEDIT_AREA
you would do this:
<informalexample>
<programlisting>
gdk_im_set_best_style (GDK_IM_PREEDIT_AREA);
</programlisting>
</informalexample>
Or to set the best allowed pre-edit style to %GDK_IM_PREEDIT_POSITION and the
best allowed status style to %GDK_IM_STATUS_NOTHING you can do this:
<informalexample>
<programlisting>
gdk_im_set_best_style (GDK_IM_PREEDIT_POSITION | GDK_IM_STATUS_NOTHING);
</programlisting>
</informalexample>
</para>
@best_allowed_style: a bit-mask with the best pre-edit style and/or the best
status style to use. If 0 is used, then the current bit-mask of all allowed
styles is returned.
@Returns: a bit-mask of all the styles allowed.
<!-- ##### FUNCTION gdk_im_begin ##### -->
<para>
Starts editing, using the given input context and #GdkWindow.
This should be called when the widget receives the input focus, typically in
the widget's focus_in_event method.
</para>
@ic: a #GdkIC.
@window: the #GdkWindow which will be receiving the key press events.
<!-- ##### FUNCTION gdk_im_end ##### -->
<para>
Stops editing using the input method.
This should be called when the widget loses the input focus, typically in
the widget's focus_out_event method.
</para>

<!-- ##### SECTION Short_Description ##### -->
functions to manipulate properties on windows.
<!-- ##### SECTION Long_Description ##### -->
<para>
Each window under X can have any number of associated
<firstterm>properties</firstterm> attached to it.
Properties are arbitrary chunks of data identified by
<firstterm>atom</firstterm>s. (An <firstterm>atom</firstterm>
is a numeric index into a string table on the X server. They are used
to transfer strings efficiently between clients without
having to transfer the entire string.) A property
has an associated type, which is also identified
using an atom.
</para>
<para>
A property has an associated <firstterm>format</firstterm>,
an integer describing how many bits are in each unit
of data inside the property. It must be 8, 16, or 32.
When data is transfered between the server and client,
if they are of different endianesses it will be byteswapped
as necessary according to the format of the property.
Note that on the client side, properties of format 32
will be stored with one unit per <emphasis>long</emphasis>,
even if a long integer has more than 32 bits on the platform.
(This decision was apparently made for Xlib to maintain
compatibility with programs that assumed longs were 32
bits, at the expense of programs that knew better.)
</para>
<para>
The functions in this section are used to add, remove
and change properties on windows, to convert atoms
to and from strings and to manipulate some types of
data commonly stored in X window properties.

<!-- ##### FUNCTION gdk_text_property_to_text_list ##### -->
<para>
Convert a text string from the encoding as it is stored in
a property into an array of strings in the encoding of
the current local. (The elements of the array represent
the null-separated elements of the original text string.)
</para>
@encoding: an atom representing the encoding. The most common
values for this are <literal>STRING</literal>,
or <literal>COMPOUND_TEXT</literal>. This is
value used as the type for the property.
@format: the format of the property.
@text: the text data.
@length: the length of the property, in item.s
@list: location to store a terminated array of strings
in the encoding of the current locale. This
array should be freed using gdk_free_text_list().
@Returns: the number of strings stored in @list, or 0,
if the conversion failed.
<!-- ##### FUNCTION gdk_free_text_list ##### -->
<para>
Free the array of strings created by
gdk_text_property_to_text_list().
</para>
@list: the value stored in the @list parameter by

<!-- ##### FUNCTION gdk_string_to_compound_text ##### -->
<para>
Convert a string from the encoding of the current locale
into a form suitable for storing in a window property.
</para>
@str: a null-terminated string.
@encoding: location to store the encoding atom (to be used as the type for the property).
@format: location to store the format for the property.
@ctext: location to store newly allocated data for the property.
@length: location to store the length of @ctext in items.
@Returns: 0 upon sucess, non-zero upon failure.
<!-- ##### FUNCTION gdk_free_compound_text ##### -->
<para>
Free the data returned from gdk_string_to_compound_text().
</para>
@ctext: The pointer stored in @ctext from a call to gdk_string_to_compound_text().
<!-- ##### FUNCTION gdk_atom_intern ##### -->
<para>
Find or create an atom corresponding to a given string.
</para>
@atom_name: a string.
@only_if_exists: if %TRUE, do not create a new atom, but
just return the atom if it already exists.
@Returns: the atom corresponding to @atom_name, or, if
@only_if_exists is false, and an atom does not
already exists for the string, %GDK_NONE.
<!-- ##### FUNCTION gdk_atom_name ##### -->
<para>
Determine the string corresponding to an atom.
</para>
@atom: a #GdkAtom.
@Returns: a newly allocated string containing the string
corresponding to @atom. When you are done
with the return value, you should free it
using g_free().
<!-- ##### FUNCTION gdk_property_get ##### -->
<para>
Retrieves a portion of the contents of a property. If the
property does not exist, then the function returns FALSE,
and %GDK_NONE will be stored in @actual_property_type.
Note: the <function>XGetWindowProperty()</function>
function that gdk_property_get()
uses has a very confusing and complicated set of semantics.
Unfortunately, gdk_property_get() makes the situation
worse instead of better (the semantics should be considered
undefined), and also prints warnings to stderr in cases where it
should return a useful error to the program. You are advised to use
<function>XGetWindowProperty()</function>
directly until a replacement function for gdk_property_get()
is provided.
</para>
@window: a #GdkWindow.
@property: the property to retrieve.
@type: the desired property type, or 0, if any type of data
is acceptable. If this does not match the actual
type, then @actual_format and @actual_length will
be filled in, a warning will be printed to stderr
and no data will be returned.
@offset: the offset into the property at which to begin
retrieving data. (in 4 byte units!)
@length: the length of the data to delete. (in bytes, but
the actual retrieved length will be the next
integer multiple multiple of four greater than
this!)
@pdelete: if %TRUE, delete the property after retrieving the
data.
@actual_property_type: location to store the actual type of
the property.
@actual_format: location to store the actual format of the data.
@actual_length: location to store the length of the retrieved
data, in bytes.
@data: location to store a pointer to the data. The retrieved

<!-- ##### SECTION Title ##### -->
GdkRGB
<!-- ##### SECTION Short_Description ##### -->
displays RGB images (as well as grayscale and colormapped) to
the native window.
<!-- ##### SECTION Long_Description ##### -->
<para>
GdkRgb converts RGB, grayscale, and colormapped images into the native
window pixel format and displays them. It takes care of colormaps,
visuals, dithering, and management of the temporary buffers.
</para>
<para>
You must call gdk_rgb_init() before using any GdkRgb functionality. If
you fail to do so, expect coredumps. All Gtk+ widgets that use GdkRgb
(including #GtkPreview) call gdk_rgb_init() in their class_init method.
Thus, if you use GdkRgb only indirectly, you don't need to worry
about it.
</para>
<para>
GdkRgb tries to use the system default visual and colormap, but
doesn't always succeed. Thus, you have to be prepared to install the
visual and colormap generated by GdkRgb. The following code sequence
(before any widgets are created) should work in most applications:
</para>
<informalexample>
<programlisting>
gdk_rgb_init ();
gtk_widget_set_default_colormap (gdk_rgb_get_cmap ());
gtk_widget_set_default_visual (gdk_rgb_get_visual ());
</programlisting>
</informalexample>
<para>
You can also push the colormap and visual, but in general it doesn't
work unless the push wraps the window creation call. If you wrap the
push around a widget which is embedded in a window without the GdkRgb
colormap and visual, it probably won't work, and is likely to cause
colormap flashing, as well.
</para>
<para>
On 8-bit systems, the colormaps used by Imlib and GdkRgb may
conflict. There is no good general solution to this other than phasing
out the dependence on Imlib.
</para>
<para>
You can set the threshold for installing colormaps with
gdk_rgb_set_min_colors (). The default is 5x5x5 (125). If a colorcube
of this size or larger can be allocated in the default colormap, then
that's done. Otherwise, GdkRgb creates its own private colormap.
Setting it to 0 means that it always tries to use the default
colormap, and setting it to 216 means that it always creates a private
one if it cannot allocate the 6x6x6 colormap in the default. If you
always want a private colormap (to avoid consuming too many colormap
entries for other apps, say), you can use gdk_rgb_set_install(TRUE).
Setting the value greater than 216 exercises a bug in older versions
of GdkRgb. Note, however, that setting it to 0 doesn't let you get
away with ignoring the colormap and visual - a colormap is always
created in grayscale and direct color modes, and the visual is changed
in cases where a "better" visual than the default is available.

<!-- ##### FUNCTION gdk_rgb_init ##### -->
<para>
Initializes GdkRgb statically. It may be called more than once with no
ill effects. It must, however, be called before any other GdkRgb
operations are performed.
</para>
<para>
The GdkRgb "context" is allocated statically. Thus, GdkRgb may be used
to drive only one visual in any given application. GdkRgb
automatically selects a best visual and sets its own colormap, if
necessary. gdk_rgb_get_visual() and gdk_rgb_get_cmap () retrieve
the chosen visual and colormap, respectively.
</para>
<!-- ##### FUNCTION gdk_draw_rgb_image ##### -->
<para>
Draws an RGB image in the drawable. This is the core GdkRgb
function, and likely the only one you will need to use other than the
initialization stuff.
</para>
<para>
The @rowstride parameter allows for lines to be aligned more flexibly.
For example, lines may be allocated to begin on 32-bit boundaries,
even if the width of the rectangle is odd. Rowstride is also useful
when drawing a subrectangle of a larger image in memory. Finally, to
replicate the same line a number of times, the trick of setting
@rowstride to 0 is allowed.
</para>
<para>
In general, for 0 &lt;= i &lt; @width and 0 &lt;= j &lt; height,
the pixel (x + i, y + j) is colored with red value @rgb_buf[@j *
@rowstride + @i * 3], green value @rgb_buf[@j * @rowstride + @i * 3 +
1], and blue value @rgb_buf[@j * @rowstride + @i * 3 + 2].
</para>
@drawable: The #GdkDrawable to draw in (usually a #GdkWindow).
@gc: The graphics context (all Gdk drawing operations require one; its
contents are ignored).
@x: The x coordinate of the top-left corner in the drawable.
@y: The y coordinate of the top-left corner in the drawable.
@width: The width of the rectangle to be drawn.
@height: The height of the rectangle to be drawn.
@dith: A #GdkRgbDither value, selecting the desired dither mode.
@rgb_buf: The pixel data, represented as packed 24-bit data.
@rowstride: The number of bytes from the start of one row in @rgb_buf to the
start of the next.
<!-- ##### FUNCTION gdk_draw_rgb_image_dithalign ##### -->
<para>
Draws an RGB image in the drawable, with an adjustment for dither alignment.
</para>
<para>
This function is useful when drawing dithered images into a window
that may be scrolled. Pixel (x, y) will be drawn dithered as if its
actual location is (x + @xdith, y + @ydith). Thus, if you draw an
image into a window using zero dither alignment, then scroll up one
pixel, subsequent draws to the window should have @ydith = 1.
</para>
<para>
Setting the dither alignment correctly allows updating of small parts
of the screen while avoiding visible "seams" between the different
dither textures.
</para>
@drawable: The #GdkDrawable to draw in (usually a #GdkWindow).
@gc: The graphics context.
@x: The x coordinate of the top-left corner in the drawable.
@y: The y coordinate of the top-left corner in the drawable.
@width: The width of the rectangle to be drawn.
@height: The height of the rectangle to be drawn.
@dith: A #GdkRgbDither value, selecting the desired dither mode.
@rgb_buf: The pixel data, represented as packed 24-bit data.
@rowstride: The number of bytes from the start of one row in @rgb_buf to the
start of the next.
@xdith: An x offset for dither alignment.
@ydith: A y offset for dither alignment.
<!-- ##### FUNCTION gdk_draw_indexed_image ##### -->
<para>
Draws an indexed image in the drawable, using a #GdkRgbCmap to assign
actual colors to the color indices.
</para>
@drawable: The #GdkDrawable to draw in (usually a #GdkWindow).
@gc: The graphics context.
@x: The x coordinate of the top-left corner in the drawable.
@y: The y coordinate of the top-left corner in the drawable.
@width: The width of the rectangle to be drawn.
@height: The height of the rectangle to be drawn.
@dith: A #GdkRgbDither value, selecting the desired dither mode.
@buf: The pixel data, represented as 8-bit color indices.
@rowstride: The number of bytes from the start of one row in @buf to the
start of the next.
@cmap: The #GdkRgbCmap used to assign colors to the color indices.
<!-- ##### FUNCTION gdk_draw_gray_image ##### -->
<para>
Draws a grayscale image in the drawable.
</para>
@drawable: The #GdkDrawable to draw in (usually a #GdkWindow).
@gc: The graphics context.
@x: The x coordinate of the top-left corner in the drawable.
@y: The y coordinate of the top-left corner in the drawable.
@width: The width of the rectangle to be drawn.
@height: The height of the rectangle to be drawn.
@dith: A #GdkRgbDither value, selecting the desired dither mode.
@buf: The pixel data, represented as 8-bit gray values.
@rowstride: The number of bytes from the start of one row in @buf to the
start of the next.
<!-- ##### FUNCTION gdk_draw_rgb_32_image ##### -->
<para>
Draws a padded RGB image in the drawable. The image is stored as one
pixel per 32-bit word. It is laid out as a red byte, a green byte, a
blue byte, and a padding byte.
</para>
<para>
It's unlikely that this function will give significant performance
gains in practice. In my experience, the performance gain from having
pixels aligned to 32-bit boundaries is cancelled out by the increased
memory bandwidth.
</para>
@drawable: The #GdkDrawable to draw in (usually a #GdkWindow).
@gc: The graphics context.
@x: The x coordinate of the top-left corner in the drawable.
@y: The y coordinate of the top-left corner in the drawable.
@width: The width of the rectangle to be drawn.
@height: The height of the rectangle to be drawn.
@dith: A #GdkRgbDither value, selecting the desired dither mode.
@buf: The pixel data, represented as padded 32-bit data.
@rowstride: The number of bytes from the start of one row in @buf to the
start of the next.
<!-- ##### ENUM GdkRgbDither ##### -->
<para>
Selects whether or not GdkRgb applies dithering
to the image on display. There are three values:
</para>
<itemizedlist>
<listitem>
<para>
%GDK_RGB_DITHER_NONE: Never use dithering.
</para>
</listitem>
<listitem>
<para>

<listitem>
<para>
%GDK_RGB_DITHER_MAX: Use dithering in 16 bits per pixel and below.
</para>
</listitem>

<para>
Since GdkRgb currently only handles images with 8 bits per component,
dithering on 24 bit per pixel displays is a moot point.
</para>
@GDK_RGB_DITHER_NONE:
@GDK_RGB_DITHER_NORMAL:
@GDK_RGB_DITHER_MAX:
<!-- ##### FUNCTION gdk_rgb_cmap_new ##### -->
<para>
Creates a new #GdkRgbCmap structure. The cmap maps color indexes to
RGB colors. If @n_colors is less than 256, then images containing
color values greater than or equal to @n_colors will produce undefined
results, including possibly segfaults.
</para>
@colors: The colors, represented as 0xRRGGBB integer values.
@n_colors: The number of colors in the cmap.
@Returns: The newly created #GdkRgbCmap

<para>
Frees the memory associated with a #GdkRgbCmap created by gdk_rgb_cmap_new().
</para>
@cmap: The #GdkRgbCmap to free.

colors. This is used only for gdk_draw_indexed_image().
</para>

@lut:
<!-- ##### FUNCTION gdk_rgb_gc_set_foreground ##### -->
<para>
Sets the foreground color in @gc to the specified color (or the
closest approximation, in the case of limited visuals).
</para>
@gc: The #GdkGC to modify.
@rgb: The color, represented as a 0xRRGGBB integer value.
<!-- ##### FUNCTION gdk_rgb_gc_set_background ##### -->
<para>
Sets the background color in @gc to the specified color (or the
closest approximation, in the case of limited visuals).
</para>
@gc: The #GdkGC to modify.
@rgb: The color, represented as a 0xRRGGBB integer value.
<!-- ##### FUNCTION gdk_rgb_xpixel_from_rgb ##### -->
<para>
Finds the X pixel closest in color to the @rgb color specified. This
value may be used to set the <structfield>pixel</structfield> field of
a #GdkColor struct.
</para>
@rgb: The color, represented as a 0xRRGGBB integer value.
@Returns: The X pixel value.
<!-- ##### FUNCTION gdk_rgb_set_install ##### -->
<para>
If @install is TRUE, directs GdkRgb to always install a new "private"
colormap rather than trying to find a best fit with the colors already
allocated. Ordinarily, GdkRgb will install a colormap only if a
sufficient cube cannot be allocated.
</para>
<para>
A private colormap has more colors, leading to better quality display,
but also leads to the dreaded "colormap flashing" effect.
</para>
@install: TRUE to set install mode.
<!-- ##### FUNCTION gdk_rgb_set_min_colors ##### -->
<para>
Sets the minimum number of colors for the color cube. Generally,
GdkRgb tries to allocate the largest color cube it can. If it can't
allocate a color cube at least as large as @min_colors, it installs a
private colormap.
</para>
@min_colors: The minimum number of colors accepted.
<!-- ##### FUNCTION gdk_rgb_get_visual ##### -->
<para>
Gets the visual chosen by GdkRgb. This visual and the corresponding
colormap should be used when creating windows that will be drawn in by GdkRgb.
</para>
@Returns: The #GdkVisual chosen by GdkRgb.
<!-- ##### FUNCTION gdk_rgb_get_cmap ##### -->
<para>
Gets the colormap set by GdkRgb. This colormap and the corresponding
visual should be used when creating windows that will be drawn in by GdkRgb.
</para>
@Returns: The #GdkColormap set by GdkRgb.
<!-- ##### FUNCTION gdk_rgb_ditherable ##### -->
<para>
Determine whether the visual is ditherable. This function may be
useful for presenting a user interface choice to the user about which
dither mode is desired; if the display is not ditherable, it may make
sense to gray out or hide the corresponding UI widget.
</para>
@Returns: TRUE if the visual is ditherable.
<!-- ##### FUNCTION gdk_rgb_set_verbose ##### -->
<para>
Sets the "verbose" flag. This is generally only useful for debugging.
</para>
@verbose: TRUE if verbose messages are desired.

<!-- ##### SECTION Short_Description ##### -->
functions for transfering data via the X selection mechanism.
<!-- ##### SECTION Long_Description ##### -->
<para>
The X selection mechanism provides a way to transfer
arbitrary chunks of data between programs.
A <firstterm>selection</firstterm> is a essentially
a named clipboard, identified by a string interned
as a #GdkAtom. By claiming ownership of a selection,
an application indicates that it will be responsible
for supplying its contents. The most common
selections are <literal>PRIMARY</literal> and
<literal>CLIPBOARD</literal>.
</para>
<para>
The contents of a selection can be represented in
a number of formats, called <firstterm>targets</firstterm>.
Each target is identified by an atom. A list of
all possible targets supported by the selection owner
can be retrieved by requesting the special target
<literal>TARGETS</literal>. When a selection is
retrieved, the data is accompanied by a type
(an atom), and a format (an integer, representing
the number of bits per item).
See <link linkend="gdk-Properties-and-Atoms">Properties and Atoms</link>
for more information.
</para>
<para>
The functions in this section only contain the lowlevel
parts of the selection protocol. A considerably more
complicated implementation is needed on top of this.
GTK+ contains such an implementation in the functions
in <literal>gtkselection.h</literal> and programmers
should use those functions instead of the ones presented
here. If you plan to implement selection handling
directly on top of the functions here, you should refer
to the X Inter-client Communication Conventions Manual

The way that the data stored on the screen is stored
in memory can vary considerably between different X
servers; some X servers even support multiple formats
used simultaneously. An X <firstterm>visual</firstterm>
represents a particular format for screen data.
It includes information about the number of bits
used for each color, the way the bits are translated
into an RGB value for display, and the way the bits
are stored in memory.
</para>

There are several standard visuals. The visual returned
by gdk_visual_get_system() is the system's default
visual. gdk_rgb_get_visual() return the visual most

using this visual (and the colormap returned by
gdk_rgb_get_colormap()).

A number of functions are provided for determining
the "best" available visual. For the purposes of
making this determination, higher bit depths are

available.
<!-- ##### FUNCTION gdk_visual_ref ##### -->
<para>
In theory, increases the reference count of a visual. However,
the set of visuals is determined statically when GTK+ is
initialized, so this operation does nothing.
</para>
@visual: a #GdkVisual.
@Returns: @visual.
<!-- ##### FUNCTION gdk_visual_unref ##### -->
<para>
In theory, decreases the reference count of a visual. Like
gdk_visual_ref(), this operation does nothing.

<title>GTK+ </title>
<para>
GTK+ is a multi-platform open source GUI Toolkit. Everything about
GTK+ from the object-oriented design to the Free Software LGPL
licensing allows you to code your project with the most freedom
possible. You can develop open software, free software, or even
commercial non-free software without having to spend a dime for
licenses or royalties.
</para>
<para>
GTK+ is a set of libraries to create graphical user interfaces. It
works on many Unix-like platforms, and a Windows version is in
development. GTK+ is released under the GNU Library General Public
License (GNU LGPL), which allows for flexible licensing of client
applications. GTK+ has a C-based object-oriented architecture that
allows for maximum flexibility. Bindings for other languages have
been written, including C++, Objective-C, Guile/Scheme, Perl, Python,
TOM, Ada95, Free Pascal, and Eiffel.
