Ok, thanks for the info :)

Ahh.. that's a nice pointer Gonzalo :)

It seems that only "size-allocate" and "request-clear-area" are the signals
to be considered (not sure though; again, can only  verify after a couple
of days).

If these signals are in fact emitted when the OSK appears/disappears by
pressing a game key, I think we should be done. We would have found a hack
:)

Keeping fingers crossed, and waiting eagerly for my XO-4-Touch to arrive.
