Ah, it seems that you were setting up the scene from with a method of

That might fix the problem. Another question worth asking is: have the
resources been set up correctly? The assignment,

I think you are drawing your pixmap off the edge of the scene. Try the

pic = QtGui.QPixmap(":/images/triangle.png")
scene.addItem(QtGui.QGraphicsPixmapItem(pic))
