DefinitionObserver interface

This observer interface is implemented to react to component definition events. To implement this observer, create a Ruby class of this type, override the desired methods, and add an instance of the observer to the objects of interests.

class MyEntityObserver <  Sketchup::EntityObserver
 	def onEntityChanged (entity)


		# do something

	end

end

# In your code. If the face changes, MyEntityObserver is called.

face.add_observer(MyEntityObserver.new)
