[Qt-interest] QWidget backgroup to white

[Alexandre Beraud]

Hi,

If you draw waves on your widget, then I assume that you have redefined 
the paintEvent() of the widget. In that case why not just call 
QPainter::fillRect() ? Also, if you really want to freely draw on a 
widget, I would advise to use QGraphicsScene/QGraphicsView, and use the 
setBackgroundBrush() method.

Regards,

Alex
