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.
Make gtk_popover_new_from_model() return a GtkPopoverMenu,
rename it to gtk_popover_menu_new_from_model() and add
a relative_to argument to gtk_popover_menu_new().
Update all callers.
We can't improve popover menus as long as we
have to be able to work with any old popover
we're given. Remove this, so we can make
gtk_popover_new_from_model return a subclass.
These need to be skipped in measuring,
and we need to call gtk_native_check_resize
on them during allocation.
This was showing up as the new-style
context menu in widget-factory forcing
its relative-to box to grow when its
shown.
We only want to reserve indicator size if
there are any checks or radios in the popover.
Unfortunately, GtkIcon has a hardcoded min-size
of 16, defeating this use. Work around by
wrapping each indicator in a box, and showing/
hiding the actual indicator.
