QtDataVisualization with OpenGL

[Cupras]

Hello,

i have a old mfc program which i want to extend with funktionality from QtDataVisualization.
The old mfc program uses OpenGL to render some stuff.
The context is created with "wglCreateContext(..)" with the CWnd of the program..

When i open e.g. a Q3DBars as a new qt window, my OpenGL stuff in the mfc app disappears.

Is there any way to show both at the same time?
