Most of the surface api we have in the Wayland backend
only makes sense for toplevels, so reshuffle things to
take a GdkToplevel instead of a GdkSurface.
Update all callers and the docs.
Commit 658719a205 moved the call to
gtk_window_compute_default_size() outside the
if (priv->needs_default_size)
but unfortunately, that function cleared that field,
so we never entered the branch.
Keep the setting of priv->needs_default_size in the
branch, where it belongs.
GTK will not up front know how to correctly calculate a size, since it
will not be able to reliably predict the constraints that may exist
where it will be mapped.
Thus, to handle this, calculate the size of the toplevel by having GDK
emitting a signal called 'compute-size' that will contain information
needed for computing a toplevel window size.
This signal may be emitted at any time, e.g. during
gdk_toplevel_present(), or spontaneously if constraints change.
This also drops the max size from the toplevel layout, while moving the
min size from the toplevel layout struct to the struct passed via the
signal,
This needs changes to a test case where we make sure we process
GDK_CONFIGURE etc, which means we also needs to show the window and
process all pending events in the test-focus-chain test case.
Emit crossing events when the active window changes.
We don't want to emit GTK_CROSSING_FOCUS events, since
every window has its own focus location (focus does not
jump from window to window), so we use the new
GTK_CROSSING_ACTIVE type of crossing event for this.
It's not a portable API, so remove it. The corresponding backend
specific functions are still available, if they were implemented, e.g.
gdk_macos_monitor_get_workarea() and gdk_x11_monitor_get_workarea().

ATK served us well for nearly 20 years, but the world has changed, and
GTK has changed with it. Now ATK is mostly a hindrance towards improving
the accessibility stack:
- it maps to a very specific implementation, AT-SPI, which is Linux and
Unix specific
- it requires implementing the same functionality in three different
layers of the stack: AT-SPI, ATK, and GTK
- only GTK uses it; every other Linux and Unix toolkit and application
talks to AT-SPI directly, including assistive technologies
Sadly, we cannot incrementally port GTK to a new accessibility stack;
since ATK insulates us entirely from the underlying implementation, we
cannot replace it piecemeal. Instead, we're going to remove everything
and then incrementally build on a clean slate:
- add an "accessible" interface, implemented by GTK objects directly,
which describe the accessible role and state changes for every UI
element
- add an "assistive technology context" to proxy a native accessibility
API, and assign it to every widget
- implement the AT context depending on the platform

We only want to send grab-notify to widgets that might have been
interacting with devices via events. Instead of going through all
widgets in all toplevels, we have the window/pointer focus information,
so we can just traverse the widget stacks for every involved foci.
This got stuck in ancient times when widgets were windowed, so the devices
in a window to know the devices in that widget would pan out. We do only
want here the devices that are inside the widget, not spread over the
surface, so rewrite this helper function to poke the toplevel foci, and
look they are contained inside the widget.
If you run weston with the headless backend, you get a Wayland
display with no seat, which is just fine by the protocol.
gdk_display_get_default_seat() returns NULL in this case. Various
widgets assume that we always have a seat with a keyboard and a
pointer, since that is what X guarantees. Make things survive
without that, so we can run the testsuite under a headless
Wayland compositor.
The previous code was unreffing the window twice, which caused problems
during dialog destruction. Move to g_list_store_find instead of
iterating manually.
ref() the window before and unref() after. g_list_store_remove will
actually unref() the window, since the toplevel_list owns its own
reference.

I thought I could get away with just unrealizing the
window, but it turns out that gtk_window_hide() is the
place where we remove grabs when a modal dialog goes
away, so we ended up with stuck grabs.
Don't call gtk_widget_destroy; instead implement
gtk_window_destroy outselves by removing the window
from the toplevel lista and dropping the reference that
GTK holds.
Since GtkWindowHandle and GtkHeaderBar do it now, it can be removed from
GtkWindow, along with GTK_WINDOW_REGION_TITLE which at this point doesn't
differ from GTK_WINDOW_REGION_CONTENT.
Closes https://gitlab.gnome.org/GNOME/gtk/-/issues/2689, since
GtkWindowHandle doesn't do that anymore.
Add private gtk_tooltip_maybe_allocate() function
and use it from GtkWindow and GtkPopover.
This will let us stop using the ::size-allocate signal,
without having to redo all the tooltip management first.
That will happen later.
We want to remove GtkBin and GtkContainer as they don't
provide much useful functionality anymore. This requires
us to move get_request_mode and compute_expand down.
Update the accessible implementation to match, remove
remnants of container implementations in GtkWindow
subclasses, and fix livecycle issues around destroy
vs dispose in GtkAssistant.
After this commit, using gtk_container_add on window
subclasses is not allowed anymore, but adding childing
with <child> in ui files still works.
See #2681
Use window title, or custom title widget if it's set. Remove 'title'
property.
Update demos and tests to set the title on the window instead of
headerbar.
The `element-type` annotation is for GList and GSList only, and turns
out adding support for GListModel in gobject-introspection breaks Vala
and the GIR for GIO.
Instead of using `element-type`, we can use the `attributes` annotation,
which is ignored by code generators based on the GIR data.
This function to revoke implicit grabs may be called with a NULL
device, which means all devices should be revoked. Fix the check
so this actually happens.
Fixes implicit grabs (maybe) being unset in result to a GTK grab.
Update the layout when any of the following properties changes:
* modal
* transient-for
* resizable
* deletable
Stop updating it from GtkWindow, make that function static.
