Hello,
Let me make myself clear.
I have a renderwindow in python/Tkinter(
ren_widget = vtkRenderWidget.vtkTkRenderWidget( frame )
ren_win = ren_widget.GetRenderWindow()
Now i want to pass this ren_win to a c++ class which adds renderers to it 
and returns ren_win.
In my python code i will say ren_win.render().
how to acheive this.
with some code example.


thanks
dharmendra
