commit 09400b6bfe0496b119a8033ddd554f5557b33039
Author: Emmanuele Bassi <ebassi gnome org>
Date: Thu Feb 6 15:43:55 2020 +0000
Add GtkShortcutManager
This adds an interface for taking care of shortcut controllers with
managed scope.
Only GtkWindow currently implements this interface, so we need to ensure
that we check if any top-level widget we reach is a shortcuts manager
before we call into it.
