Ah, it seems that you were setting up the scene from with a method of a class. Your problem was that, when the method returned, the scene was garbage collected. Giving it a parent of "self" keeps it alive thanks to Qt's parent-child object management. Alternatively, you could have stored the scene in the instance of your class; in other words, use self.scene instead. > Now, Dave just told me it was a bad idea to put an image on a > QGraphicsView.

Well, I guess that was in some private e-mail. It really depends on what you are going to do with the image, and whether you need to use QGraphicsView to show it. > David : thanks again for your good work on the wiki. You're welcome. I notice that you have added a link to your hints and tips page. Thanks for doing that. In case you were unaware, there's an entire French speaking Qt community online at http://www.qtfr.org/ Maybe some of the people there can speak Python, too. ;-) David _______________________________________________ PyQt mailing list [email protected] http://www.riverbankcomputing.com/mailman/listinfo/pyqt
