[vtkusers] wxPython and VTK

[Mathieu Malaterre]

Aurélien,

	You shouldn't be doing something particular for Windows. I recently 
commited a patch for that -or I believe so-. Could you do me a favor, 
could you please try it instead of the

	'self.renderer.GetProps().RemoveAllItems()'

	Go to that web page, it works just like a patch :

http://vtk.org/cgi-bin/cvsweb.cgi/VTK/Rendering/vtkWin32OpenGLRenderWindow.cxx.diff?r1=1.121&r2=1.122

	And just apply the same modification to your local VTK build tree. (you 
don't need a particular revision of vtkWin32OpenGLRenderWindow.cxx).

Thanks a bunch
Mathieu
