Have you already heard about PropertyChangeEvent and associated classes (like PropertyChangeListener and PropertyChangeSupport) ? If not, go take a look at them .. And read the chapter in Java tutorial about ProperttyChangeListener. Notice that, although it’s defined in a Swing context, elements from java.beans can perfectly be used anywhere else, as they are not Swing-dependant.
