[vtkusers] ActiViz | Changing Window Level and Window Width in a RenderWindowControl

[David Cole]

Don't do this:

     vtkRenderWindowInteractor interactor = 
vtkRenderWindowInteractor.New();

Do this:

    vtkRenderWindowInteractor interactor = renderWindow.GetInteractor();

You don't need a new interactor, you just need a new interaction style 
that you push into the existing interactor.


Good luck.
