QOpenGLWindow from QOpenGLWidget

[kshegunov]

Hello,
I need to acquire instance to a QOpenGLWindow from a corresponding widget I have. Is this possible and how can one go about it?

Thanks in advance.

One does not inherit from the other so there's no way to do that.
You could, for example, embed a window in a widget with createWindowContainer(), but they share similar functions. Why do you need to turn one into another?

Hello,
I know they don't inherit one another, that's why I'm asking if it's possible. :)
I have a form with QOpenGLWidget laid out and want to use Qt3D, which does require a QWindow subclass for its painting routines. Now I was thinking maybe creating an attached QOpenGLWindow and sharing contexts but I'm not quite sure if this is the way. Anyway, createWindowsContainer is a possible solution, but I'd need to handle the layout insertion manually, this is why I'm asking.

Kind regards.
