I assume you have overwritten drawContents to draw into your ScrollView.
Usually this method is called from paintEvent by the ScrollView class itself,
but you can call it as well.
You first create a QPixmap with contentsWidth() and contensHeight() as its
Then you create a QPainter on this pixmap (QPixmap is a QPaintDevice).
Then you pass this painter to drawContents and use 0, 0, contentsWidth,
contentsHeight as the clipping parameters.
After drawContents returns, you QPixmap contains everything usually painted on
