I had a play with one of those once.  It was amazing what was on all
my cards.  However it turned out that my MCI calling card crashed
the unit, and it took 4 hours for them to get it back up again!

Anyway the answer to your question is to call SetFocus on your
window/control.  (See the documentation for wxWindow.SetFocus).
You can use EVT_KILL_FOCUS to be notified when losing focus
and grab it back again.  As for having an invisible control,
I would recommend just making it one pixel by one pixel
and setting the foreground colour to be the same as the
background colour.
