Hi all, I'm trying to create an application with several QOpenGLWidgets ( no regular QWidgets involved ), where some of them are on top of others.
My first results are promising, but I couldn't find out how to enable a transparent background for the widgets on top. I would like to have a similar effect as with setAutoFillBackground( false ) - seeing pixels from the widget below. But I also couldn't get setAutoFillBackground(true) working and had to fill widgets myself in paintGL(). As it is explicitly mentioned in the docs ( http://doc.qt.io/qt-5/qopenglwidget.html ) I guess it is something wrong on my side. When having a regular widget on top of a QOpenGLWidget everything works like expected, but with QOpenGLWidget the background is always black. Has someone ever tried this or knows if it is possible to set up QOpenGLWidget not drawing a background at all ? I'm using the Qt 5.6 beta from December. Thanks a lot, Uwe _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
