You shouldn't need anything this complicated, or this likely
to break stuff.

Widgets are sent key presses before GTK+ checks for focus keys. If the
widget handles the key press in its event handler and returns TRUE,
then GTK+ will not check for tab/arrows.

For instance, this is how GtkText prevents a tab key from tabbing out
of the GtkText widget.
