Not advice so much, but a "me too": I spent a fair chunk of time
trying to figure out how to make this work, and failed utterly.  I
can't even use your workaround, since I'm living in QGraphicsView
land, so there's no widget that it's wrapped in.

I can, however, point you at one gotcha I discovered:
http://bugreports.qt.nokia.com/browse/QTBUG-6144

I'm definitely gonna keep an eye on this thread, though - if you
figure it out, let me know!
