I'm not that person at least now - when I don't understand the whole 
picture ;).

Indeed.

Well, that needs discussion I think. What the new API will look like, what it 
should provide, how it should work...

You mean that DirectX has a special gaming subAPI? Or you're talking of a 
whole DirectX library as a Game API?

QGameView? I can't find such class in Qt (4.2-TP1 here).
Maybe you're talking about QGraphicsView?
In this case, I'll repeat, no KGameMouseIO won't work.
Because it relies on the fact that it can intercept MouseEvents coming from 
widget it operates on (it installs eventFilter on this widget), but 
QGraphicsView doesn't propagate QMouseEvents to outside world.
So KGameMouseIO+QGraphicsView=not working :).
So is KGameKeyIO.

Cheers,
Dmitry.
