Yes, that is what happens.  The only easy way I can think of doing
this is to use the vtkTkRenderWidget.

Maybe if you give us more details on this problem, it could be fixed?

Recently, Andy added a vtkpython executable that solves some of the
problems with VTK and Tkinter on non-Linux *nix platforms.  IIRC the
biggest problems arise on systems with non-gcc compilers.  Maybe you
should try with the vtkpython executable instead of vanilla Python.
