Menus traditionally don't have separate
hover and focus locations. Make the same
change here that we already did for
popover menubars: Track the active item
and set its selected state. Both keynav
and mouse change the active item.
The Wayland backend has a hack to work around
a race with popover mapping: If the surface size
changes before the initial configure, we hide and
show the surface. Unfortunately, the code was doing
this in a way that is externally observable (by
listening for surface state changes), and popovers
were observing it and hiding themselves in response.
Avoid this by not going through the GDK frontend
code for this.
This solves issues with parent widgets, like combobox
or entry, installing their own bindings for these
keys, overriding the activation behavior that
is implemented in gtkwindow.

Add a convenience api to skip children
that should not be included in the layout,
and call gtk_native_check_resize on all
native children outside of the vfunc.
We can't call gtk_widget_destroy on something
that wasn't added as a child to a container -
it ends up calling gtk_container_remove, which
asserts if it doesn't find the child.
Make gtk_widget_real_focus do the right
thing for focusable widgets with children.
A case where this is (now) relevant is
an entry with a context popover.
Differentiate between wrapping around and
stopping at the end of the focus chain.
Update the existing tests, and add two
new ones where the difference matters.
Add a test that enumerates the focus chain by
emitting move-focus repeatedly, and compares
the result to expected output.
The test expects a ui file and a reference
file as input. The reference file can be created
using the --generate option.
The new rule for focus events from the windowing
system is: We only want them for toplevels. If you
put focus on popups, we don't want to know about
it, and you still need to deliver key events to
the toplevel.
This is expected menu keynav behavior: If the
focused item has a submenu, open it on right
arrow press. And if we are in a submenu title,
make left arrow press close it.
Widgets are supposed to call gtk_widget_child_focus.
Calling internal focus_move function directly makes
us skip the childs ::focus() implementation, which
is where the magic happens.
Make left/right cycle the active item
among the bars children. Separate the styling
for the active item from :hover, since it is
a separate state, and only mixed up in menus
for historical reasons.
