I have had the same problem with transparent over OpenGL. What you might try, is to move your player widget into a QGraphicsWidget and play it in a QGraphicsView. If this works, you can make your floating widgets on the canvas.<BR>
<BR>
I’m not sure if phonon widgets can be played in this way, but they should.<BR>
<BR>
Good luck!<BR>

Hello,<BR>
<BR>
After watching the apple keynote I thought I would try to duplicate the<BR>
floating video player control they are using in the new version of<BR>
Quicktime.<BR>
<BR>
A semi-transparent widget on top of a window works fine but I have problems<BR>
when it comes to placing it over top of a playing video.<BR>
<BR>
Ultimately, I would like to have a widget with a semi-transparent background<BR>
that I can add controls to (labels with images) sitting on top of the<BR>
playing video (without any flicker).<BR>
<BR>
Its just the semi-transparent widget on top of the playing video I need help<BR>
with. Is it possible do you think? Here is a simple example of my problem<BR>
(in pyqt 4.5 using qt 4.5, python 2.6 ), thanks ...<BR>
