QImage is device independent, good for storing things in a device independent way.
QPixmap is optimized for what ever device you're painting to.
You need should probably just setBackgroundBrush(QPixmap(myPixmap));

Subject: [Qt-interest] QPixmap Vs QImage
Hi,
I need to show image on the background of QGraphicsView.
I have the data to construct both QImage & QPixmap.
But which one to use and why?
I am using void drawBackground (QPainter*
painter, const QRectF& rect ) method to show image on
QGraphicsView
