Is there a reason you aren't using WIDGET_DRAW keyboard events (introduced
in 5.6)?

I don't think so, and certainly not in a platform independent way if that is
your goal.

While it may take a little work, modify your application so that you accept
your keyboard input via WIDGET_DRAW events. You will not have to deal with
focus issues and it will be platform independent.
