If you can get access to the QWindow you can qobject_cast to check that it's a QQuickWindow. In that case you can connect to the beforeRendering() signal of the QQuickWindow using a Qt::DirectConnection, which will cause your slot to be executed on the render thread before the rendering of a frame. -- Samuel _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
