Examples of java.beans.PropertyChangeSupport.addPropertyChangeListener()

java.beans.PropertyChangeSupport.addPropertyChangeListener()
Add a PropertyChangeListener to the listener list. The listener is registered for all properties. The same listener object may be added more than once, and will be called as many times as it is added. If listener is null, no exception is thrown and no action is taken. @param listener The PropertyChangeListener to be added

        PropertyChangeListener l3 = new PropertyChangeListenerProxy("myProp",
                l2);
        MockPropertyChangeListener l4 = new MockPropertyChangeListener(src,
                "myProp", oldValue, newValue);
        sup.addPropertyChangeListener(l1);
        sup.addPropertyChangeListener(l3);
        sup.addPropertyChangeListener("myProp", l4);


        sup.firePropertyChange("myProp", oldValue.intValue(), newValue
                .intValue());
