[vtkusers] How to add vtkRenderWindowInteractor to a native Cocoa window

[Elvis Dowson]

Hi Clint,
                  Is there a way to add a vtkRenderWindowInteractor,  
to a native Cocoa window?

vtk is currently rendering on an off-screen vtk render widow, but I  
would like the vtkRenderWindowInteractor to be set to a QGraphicsView,  
and pipe the commands back to the off screen vtk render window.

Is this possible?

Best regards,

Elvis Dowson
