Even better than that, you could port Qt to Xi2.  Xi2 has a much more
rich state (including all buttons, keys, etc) which is provided in its
Enter/Leave/input events.  I'm pretty sure there's an Xi2 port floating
around in one of the billion Qt Gitorious repos, as part of the
multitouch work.

Actually, that's mainly for keyboard modifiers, so you're OK there.

Cheers,
