addPropertyChangeListener
public void addPropertyChangeListener(PropertyChangeListener listener)
Adds a PropertyChangeListener to the listener list. The listener is registered for all bound properties of this class.
If listener is null, no exception is thrown and no action is performed.
Parameters:
listener - the property change listener to be added
Since:
1.6

removePropertyChangeListener(java.beans.PropertyChangeListener), getPropertyChangeListeners()
removePropertyChangeListener
public void removePropertyChangeListener(PropertyChangeListener listener)
Removes a PropertyChangeListener from the listener list.
If listener is null, no exception is thrown and no action is performed.
Parameters:
listener - the PropertyChangeListener to be removed
Since:
1.6
See Also:
addPropertyChangeListener(java.beans.PropertyChangeListener), getPropertyChangeListeners()
getPropertyChangeListeners
public PropertyChangeListener[] getPropertyChangeListeners()
Returns an array of all the property change listeners registered on this component.
Returns:
all of this component's PropertyChangeListeners or an empty array if no property change listeners are currently registered
Since:
1.6
