Really, both should appear. I think the confusion arises because the green one lies within the space occupied by the red one. > I was expecting to see always both rectangle since the > red one is always the first one added to the scene... Sometimes the red one appears on top of the green one. Because it covers the same area as the green rectangle, it looks like only the red rectangle is added to the scene. To make the green rectangle appear on top, set a Z value for each of them, but make sure the green rectangle has a higher value than the red, like this: zone1.setZValue(0) zone2.setZValue(1) David _______________________________________________ PyQt mailing list [email protected] http://www.riverbankcomputing.com/mailman/listinfo/pyqt
