You can subscribe to region selection events using  
wxmpl.EVT_SELECTION, which is a wxPython event.  See `demos/ 
picking_points.py' for a detailed example.

Due to a failure of imagination you can currently have region  
selections zoom or emit events.  If you need to do both it'll take  
some jiggery-pokery.  Let me know if this is the case and I'll write  
something up.
