[vtkusers] VTK4/Python (Newbie) question #2: vtkRenderWindowInteractor

[David Gobbi]

Hi Elvis,

In Python (as in C++) the vtkRenderWindowInteractor will not
start working until you do

iren.Start()

but note than the Start() method will not return until you close
the window, so iren.Start() should be the last line in your
application except possibly for clean-up code that will be
run just before the application exits.

 - David
