[vtkusers] Using widgets in a vtkTkRenderWidget?

[tom fogal]

David,

	Perhaps you could use multiple threads? One thread for your GUI event loop
and one thread for a vtkRenderWindowInteractor. Just be careful not to interact
too much with VTK in the GUI event loop, or rather just be sure the methods
you are calling are thread safe (they are labeled as much in the header files,
for the most part). If you're just sharing variables among the two, I imagine
this won't be much of a problem anyway.

HTH,

-tom
