[PyQt] QGraphicsView to display a png

[Adam Tenderholt]

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

scene = QtGui.QGraphicsScene()

#scene.setSceneRect(-600,-600, 600,600)
scene.setSceneRect(-600, -600, 1200, 1200)

pic = QtGui.QPixmap(":/images/triangle.png")
scene.addItem(QtGui.QGraphicsPixmapItem(pic))
view = self.gv
view.setScene(scene)
view.setRenderHint(QtGui.QPainter.Antialiasing)
view.show()
