That code (although I didn't test it), seems fine, and should work if you are using a recent gtk version. If not, that will only work if accessibility is enabled.
Anyway, FWIW, we plan to deprecate those methods at some moment of the future: https://bugzilla.gnome.org/show_bug.cgi?id=649575#c4 If you want to track when the focus change, you can also add a global event, and filter state-change:focus events.
