[vtkusers] Destroy vtkRenderWindow before TkRenderWidget...?

[Uwe Rempler]

hi list,

maybe it would be nice to add some sample code to clarify my problem 
(read over the message i sent and noticed some possible 
misunderstandings ;-)
do you see any other way for multiple render-sub-windows using tkinter() 
or should i better switch to another gui-toolkit like qt/gtk+ or maybe 
wxwindow?


cheers

uwe
