[vtkusers] mouse events

[Galen Wilkerson]

Hi,

I'm trying to understand how to capture mouse events in VTK with Python.

It looks like I have to write my own Start() method for 
vtkRenderWindowInteractor , but I'm guessing.

If there are any simple examples of this, I'd be grateful.
(For instance, how to select an object that is displayed on the screen by 
clicking on it, or dragging over it.)

thanks,
