[Qt-interest] transparent mainwindow and non transparent widget

[Bart Swinnen]

Hi

I can't figure out how to set my mainwindow transparent (no background, 
no borders)
and still having a widget showing without transparency.
In other words I need to have a widget(QLable) floating on top of an 
other application only showing the QPixmap in tha widget.
Any sugestions are welcome.

Kind regards
Bart
