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

[David Cole]

Zoom, pan and rotation are built in to the default interactor style 
that you get when you create a vtkRenderWindow (which the 
RenderWindowControl does for you).

If you want one that provides WW/WL control in the interactor style, 
you just have to instantiate a style that provides that behavior and 
then set it as the current interactor style in the control's interactor.

Google around for examples on setting interactor styles, and then adapt 
one of those and call the method:

     
renderWIndowControl.GetRenderWindow().GetInteractor().SetInteractorStyle(
 ..... put the new style here .....);
