Specifies whether @widget can own the input focus.
Widget implementations should set @focusable to %TRUE in
their init() function if they want to receive keyboard input.
Note that having @focusable be %TRUE is only one of the
necessary conditions for being focusable. A widget must
also be sensitive and can-focus and not have an ancestor
that is marked as not can-focus in order to receive input
focus.
See [method@Gtk.Widget.grab_focus] for actually setting
the input focus on a widget.
