Hehe... ok, I thought you were suggesting to give the QPainter pointer to the Qt widgets...
I know it not possible with the Qt API (at least I could not find how), that is why I posted the question...

Hmm... I am not yet sure in which direction to go...
I mean, this will have to do with reimplementing the PaintEngine, which is created by the PaintDevice, which is the base for QWidget...

I have to read some more...

Thanks.
