[kepler-dev] subclassing actors: ptolemy.actor.lib.MonitorValue

I'm trying to add some additional functionality to 
ptolemy.actor.lib.MonitorValue. I created a subclass BAPMonitorValue 
that does nothing but have the BAPMonitorValue(CompositeEntity 
container, String name) constructor calling, super(container, name). 
When I open Kepler and use Tools->Instantiate Component and add my actor 
to the work area, my actor looks completely different from the normal 
MonitorValue actor.

Here's the question: How does ptolemy.actor.lib.MonitorValue get its 
look and GUI functionality (i.e., showing it's current value)? It's not 
defined in the ptolemy.actor.lib.MonitorValue class (or super classes) 
as far as I can tell.
