virtual void Value::Listener::valueChanged ( Value value)

Called when a Value object is changed.

Note that the Value object passed as a parameter may not be exactly the same object that you registered the listener with - it might be a copy that refers to the same underlying ValueSource. To find out, you can call Value::refersToSameSourceAs().

Implemented in ComboBox, and Label.
