[Qt-interest] Howto prevent usage of native winId

[Frank Hemer]

I'm developing for tabletPC using WinXP Microsoft TabletPC Edition.

On the target platform, all created widgets have a native winId (not 
intentionaly forces by any QApplication attribute or such).
That does not happen on a plain WinXP, Linux or others.

This causes several problems - as f.e. it prevents QGraphicsEffect & friends 
from working properly.

What can be the cause of this, and how can I workaround/prevent it?

TIA,

Frank
