[vtkusers] how to clear the screen in renderer window?

[Xianjin Yang]

Instead of using RenWin->GetRenderer(), you should call
RenWin->GetRenderers(). So you get vtkRendererCollection. You may have to
loop through all renderers in the collection to clean up the render window.
I have never done so before. There must be an easy way to go. Someone else
please share your thoughts.

I tried doing

RenWin->GetRenderer()->RemoveAllProps();

as u mentioned. I am using vtkWin32OpenGLRenderWindow for displaying the 
renderer window in the dialog box. So I get errors saying that GetRenderer()

is n ot a member.Is there any othere way to remove the actors and clear the 
screen?

Thanks in advance
