[vtkusers] Can I derive from vtkOpenGLRenderWindow for a yet unsupported window system?

Thank you David!

Your comment makes me confident, that I am on the right track. So all I have to do is make vtkGraphicsFactory::CreateInstance("vtkRenderWindow") return a vtkNewOpenGLRenderWindow? (And of course, implement this new class?)

I have tried this already, but something went wrong, don't remember exactly. But if you say it's the right approach, I'll repeat the attempt.

Are any modifications or extensions of vtkRenderer necessary? I don't think so, because I derive the new class from vtkOpenGLRenderer which should take care of  the communication with the vtkRenderer. Can you confirm this?
 
Thanks again
