How to draw a QPixmap with rounded corners?

I have inherited from QGraphicsPolygonItem and would like to draw a QPixmap on the top of the item. The item itself and the pixmap should be drawn with rounded corners.

How would you this?

Solution

  • If you want to draw QPixmap with rounded corners then inside of paint event create QBrush from QPixmap and apply it to the painter like that:

    painter->setRenderHint(QPainter::Antialiasing, true);
QBrush brush = QBrush(pixmap);
painter->setBrush(brush);
painter->drawRoundedRect(polygon().boundingRect(), 5, 5);
