I got on IRC, and got a suggestion to have it work by wrapping the render call in an QPainter wrapping the QPdfWriter. _printer = new QPdfWriter (filename); _printer->setResolution(150); QPainter widgetRenderer(_printer); section->render(&widgetRenderer, QPoint(0, verticalOffset), QRegion(),QWidget::DrawChildren); The intermediary widgetRenderer doesn't end the painting on the PDF. :-) _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
