I found my mistake, a very basic one. I was using VTKscene = QVTKRenderWindowInteractor(self) but should have been using VTKscene = QVTKRenderWindowInteractor(page_VTK)
where page_VTK is the widget I created to display the scene. I apologize for cluttering up the mailing list with my ignorant questions. Gib _______________________________________________ PyQt mailing list PyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
