Right, I guess QWidget::render() won't work, since it will also call the widget's paint event (not just paintBackground). A workaround could be to make a dummy widget with DontShowOnScreen set and no paint event, and the same background as your target widget, and call dummy.render(targetPainter, ..., DrawWindowBackground); In the end, we need to make QPixmap::fill(QWidget*) work using a hook like Olivier suggested, or remove it and add API in QWidget that does the same thing. This API could be renderBackground(QPainter *painter, const QPoint &offset), or another RenderFlag enum value, such as OnlyWindowBackground (default disabled). -- Samuel _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
