Is it possible to add a OpenGLWidget which inherit from QOpenGLWidget for QT5 because currently the GLWidget inherit from QGLWidget which has been deprecated.

Do you have some clue to do this ?
I saw some code with QOpenGLWidget but all of them use a osgVierwer::Viewer, but I need to use a osgViewer::CompositeViewer and add each osgViewer::View in a Qt5 widget.

The job is actually done with a QGLWidget, but they are a lot of glitches due to the complexity of the window structure and an upgrade to QOpenGLWidget will normaly fix them.

Thanks,
Tom

Good suggestion.

I know this is old, but take a look at #22. It does exactly that.

master branch has the Qt5 way of doing this

Hi there, this might be related topic: I have issues using QOpenGLWidget and OSG RTT (render to texture). It seems that QOpenGLWidget uses FBO internally and osg::Camera manages it as well, resulting in some sort of conflict.
Is there way of solving that? I can use my RTT app with QGLWidget, but switching to QOpenGLWidget make FBO render to texture stop working.
