[vtkusers] vtkRenderWindowInteractor with Python and VTK

[David Gobbi]

Hi Marcelo,

You cannot use the vtkTkRenderWidget and a vtkRenderWindowInteractor in
the same application with Python, AFAIK.  Try controlling the interaction
via the vtkTkRenderWidget.

If you really need to use both, then you might be able to get it working
by using vtkInteractorStyleUser and doing something like the following:

def TimerCallback():
    root.update() # 'root' is your Tk root window

style.SetTimerMethod(TimerCallback)

This will hopefully make the RenderWindowInteractor cause Tkinter
to update on a regular basis.  This should be used instead of
calling 'root.mainloop()'.  Like usual, the iren.Start() must be
placed at the end of your application because iren.Start() will not
return until the application is finished.

If you manage to get this working, please email the list with your
results.

  - David
