 public class DefaultSingleSelectionModel extends Object implements SingleSelectionModel, Serializable A generic implementation of SingleSelectionModel.Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beanspackage. Please seeXMLEncoder.- Since:

Method Detail- 
addChangeListenerpublic void addChangeListener(ChangeListener l) Adds aChangeListenerto the button.- Specified by:
- addChangeListenerin interface- SingleSelectionModel
- Parameters:
- l- the ChangeListener to add
 
 - 
removeChangeListenerpublic void removeChangeListener(ChangeListener l) Removes aChangeListenerfrom the button.- Specified by:
- removeChangeListenerin interface- SingleSelectionModel
- Parameters:
- l- the ChangeListener to remove
 
 - 
getChangeListenerspublic ChangeListener[] getChangeListeners() Returns an array of all the change listeners registered on thisDefaultSingleSelectionModel.- Returns:
- all of this model's ChangeListeners or an empty array if no change listeners are currently registered
- Since:
- 1.4
- See Also:
- addChangeListener(javax.swing.event.ChangeListener),- removeChangeListener(javax.swing.event.ChangeListener)
 
 - 
fireStateChangedprotected void fireStateChanged() Notifies all listeners that have registered interest for notification on this event type. The event instance is created lazily.- See Also:
- EventListenerList
 
 - 
getListenerspublic <T extends EventListener> T[] getListeners(Class<T> listenerType) Returns an array of all the objects currently registered asFooListeners upon this model.FooListeners are registered using theaddFooListenermethod.You can specify the listenerTypeargument with a class literal, such asFooListener.class. For example, you can query aDefaultSingleSelectionModelinstancemfor its change listeners with the following code:ChangeListener[] cls = (ChangeListener[])(m.getListeners(ChangeListener.class)); If no such listeners exist, this method returns an empty array.- Type Parameters:
- T- the type of- EventListenerclass being requested
- Parameters:
- listenerType- the type of listeners requested; this parameter should specify an interface that descends from- java.util.EventListener
- Returns:
- an array of all objects registered as
          FooListeners on this model, or an empty array if no such listeners have been added
- Throws:
- ClassCastException- if- listenerTypedoesn't specify a class or interface that implements- java.util.EventListener

- 1.3
