How to set QGraphicsWebView background transparent?

[devSJ]

I have background video playing or showing another application, then launch webapp which uses QGraphicsWebView. I would like to able to see the background application or video. How could I make QGraphicsWebView to have transparent background? QWebView works in that way, but I have not find a way to set with QGraphicsWebView. Thanks!

Something like this should do the job

view->setStyleSheet("background:transparent");
view->setAttribute(Qt::WA_TranslucentBackground);
view->setAttribute(Qt::WA_OpaquePaintEvent, false);
scene.setBackgroundBrush(QBrush(Qt::transparent));
