[vtkusers] Question with "AddObserver" from C# Kitware.VTK

Are you using ActiViz .NET?

The BoxWidget example that comes with ActiViz .NET shows how to sign up 
for VTK events like this:

         boxWidget.EndInteractionEvt += new 

     public static void SelectPolygons(vtkObject sender, 
vtkObjectEventArgs e)

So... you should be able to do something similar with "KeyPressEvt" on 
the "iren" object.

Also, the EventMonitor example demonstrates how to hook/unhook events, 
and what types of variables you need to hold onto in order for events 
to work well from C#.
