We've started to turns containers into widgets which
just happen to have children, and some of these need
to be exposed to the a11y stack.
This adds a very minimal implementation, it does not
currently emit change notification when children are
added or removed.
We use a compilation symbol in our build to allow the inclusion of
specific headers while building GTK, to avoid the need to include only
the global header.
Each namespace has its own compilation symbol because we used to have
different libraries, and strict symbol visibility between libraries;
now that we have a single library, and we can use private symbols across
namespaces while building GTK, we should have a single compilation
symbol, and simplify the build rules.
The "iconified" state is mostly an X11-ism; every other platform calls
this state "minimized" because it may not involve turning a window into
an icon at all.
The renaming of this function doesn't make much since because the window
is the GtkTextWindowType, not GdkWindow specifically. So we can keep the
old name which is closer to the proper meaning and less code for consumers
to change when porting to 4.x.
Now that roots can have parent widgets, we need to
carefully examine all calls of gtk_widget_get_toplevel,
and replace them with gtk_widget_get_root if we want
the nearest root, and not the ultimate end of the parent
chain.
Previously, those numbers stored the values relative to the margin box
of the widget. Now they store values relative to the content box,
thereby getting rid of the last remains of weird coordinate systems.
Calling the accessibility function `grab_focus()` on a `GtkCell` under
Wayland will cause the client to crash.
This is another case of `gdk_x11_get_server_time()` being called
regardless of the actual windowing backend used.

Instead of doing all handling manually in the ::event vfunc,
set up drag/multipress gestures on icon images, and implement
emission of ::icon-press/release and DnD there.
As a side effect, the GdkEvent field in ::icon-press/release
signals has been dropped. Callers that might be interested on it
may still use gtk_get_current_event*().
The else case was wrongly resetting the accessible description on the
primary icon, which might not exist and can therefore cause a crash.

This commit introduces GtkPicture, which is supposed to complement
GtkImage.
GtkImage will be adapted to always display an icon, while
GtkPicture displays regular imagery.
We can just as well use notify::has-focus for the purpose of
focus tracking, and we can at the same time avoid emitting the
deprecated AtkObject::focus-event signal.
Use g_signal_connect_data() instead of g_signal_connect_object()
to make sure the callback gets disconnected when the data object
is destroyed. This avoids problems in garbage-collected bindings.

1b9aa1b708 ('a11y: drop the focus tracker') removed a bit too much. We
still have to emit window:activate/deactivate events. They are easy to
emit anyway.
Fixes#127
delete_range_cb is set to be called before the text suppression done by
the gtktextlayout (otherwise it does not work properly). But at that
point the cursor position is not yet up to date. We thus need to move
the accessibility cursor notification to after the actual text
suppression, by using another callback.
This fixes cursor position in brltty screen reading.
(cherry picked from commit fa6994d033)
The second parameter of the text-changed::delete event is to be the length,
not the end position. This fixes spurious text removals in brltty
screen reading.

Remove all the old 2.x and 3.x version annotations.
GTK+ 4 is a new start, and from the perspective of a
GTK+ 4 developer all these APIs have been around since
the beginning.
The main GDK thread lock is not portable and deprecated.
The only reason why gdk_threads_add_idle() and
gdk_threads_add_idle_full() exist is to allow invoking a callback with
the GDK lock held, in case 3rd party libraries still use the deprecated
gdk_threads_enter()/gdk_threads_leave() API.
Since we're removing the GDK lock, and we're releasing a new major API,
such code cannot exist any more; this means we can use the GLib API for
installing idle callbacks.
https://bugzilla.gnome.org/show_bug.cgi?id=793124
This code was doing horrible things, and the atk documentation
for the focus tracking feature says that this is deprecated and
not used anymore. So lets not do it.
We need to notify ATK the description changed when the tooltip text associated
with the widget changes and gtk_widget_accessible_get_description() would use
it as the description.
https://bugzilla.gnome.org/show_bug.cgi?id=779009
That is some old code that still uses IOChannels, and the only
pseudouser is at-spi-atk's commented out code that is still using
CORBA types.
So get rid of it now before I need to start adapting it to the new
clipboard.
Instead of returning the icon size with them, make
gtk_image_get_icon_name() and gtk_image_get_gicon() only return the icon
itself.
As a benefit, we can turn them into regular getters that return values
instead of requiring out parameters.
Instead, provide gtk_image_get_icon_size() to query the icon size.
A sideeffect is that we don't set the correct parent window on child
widgets anymore, but that is hopefully going to be fixed once we get rid
of child windows completely.
These are no longer used, instead we always covert to surface as
early as possible and drop the pixbuf.
This means we never store both the pixbuf and the surface at
for any longer time, which is wasteful. Also, its one step further
to drop GdkPixbufs from generic use in our APIs.
This drops the pixbuf property and the pixbuf getters. We keep
gtk_image_new/set_from_pixbuf, but these are small helpers that
immediately convert to a surface, and there is no way to later get
back the pixbuf you passed in.
The from file/resource codepaths are also changed to load a surface
instead of a pixbuf.
What is missing is the "allocation" part of x/y coordinates. Since
gtk_entry_realize doesn't call gtk_widget_set_window(priv->text_area),
the coordinates returned by gdk_window_get_origin don't include it.
This patch fixes this.
https://bugzilla.gnome.org/show_bug.cgi?id=784509
This patch makes that work using 1 of 2 options:
1. Add all missing enums to the switch statement
or
2. Cast the switch argument to a uint to avoid having to do that (mostly
for GdkEventType).
I even found a bug while doing that: clearing a GtkImage with a surface
did not notify thae surface property.
The reason for enabling this flag even though it is tedious at times is
that it is very useful when adding values to an enum, because it makes
GTK immediately warn about all the switch statements where this enum is
relevant.
And I expect changes to enums to be frequent during the GTK4 development
cycle.
-Wint-conversion is important because it checks casts from ints to
pointers.
-Wdiscarded-qualifiers is important to catch cases where we don't
strings when we should.
