Oops, sorry... I guess I gave you the way to override Look Inside,
not the way to override Configure...

The following example (in the Python actor library) overrides

   <entity name="PythonScript" class="ptolemy.actor.lib.python.PythonScript">
     <property name="_editorFactory" 
       <property name="attributeName" value="script"/>

The class ptolemy.vergil.toolbox.TextEditorConfigureFactory
extends ptolemy.actor.gui.EditorFactory, which is an attribute that
specifies what to do on Configure:

     /** Create an editor for configuring the specified object with the
      *  specified parent window.
      *  @param object The object to configure.
      *  @param parent The parent window, or null if there is none.
     public abstract void createEditor(NamedObj object, Frame parent);

It is up to the subclass to save any changes to the actor's parameters,
preferably by creating a ptolemy.moml.MoMLChangeRequest and then
calling requestChange() on the actor.

Hope this helps...
