Overriding QGraphicsView paintEvent function in Qt Designer

Im writing some simple python application using PyQt and QtDesigner. I've designed mainView in designer which has a QGraphicsView and some buttons inside. My question is, how should I draw shapes on that QGraphicsView?

Without QtDesigner, I would have created class extending QGraphicsView and overriden its paintEvent() method. However, Designer generates single Ui_MainWindow class, so I can't set it's QGraphicsView field to my specific subclass.

You'll want to promote the QGraphicsView to your own class that subclasses QGraphicsView. To learn how to promote widgtes in Qt Designer, see this SO post: How do I use promote to in Qt Designer in pyqt4?

In your subclass, you can override the paintEvent method is usual.
