Thanks for the clarification. I've had a look at the examples, however QWindow
is
(for now) of little interest for me, as I'm working on a desktop app, where an
OpenGL
widget is just an element among others of the overall GUI. Whereas QWindow and
others
are made for GL-only GUIs (no QWidgets), if I understood things well.
