Adds an ActionListener to the model.

Adds a ChangeListener to the model.

  Adds a listener to receive item events when the state of an item is changed by the user.

  Adds a listener to receive item events when the state of an item is
changed by the user. Item events are not sent when an item's
state is set programmatically. If l is
null, no exception is thrown and no action is performed.

  Notifies all listeners that have registered interest for notification on this event type.

  Notifies all listeners that have registered interest for
notification on this event type.
Parameters:
- e - the ActionEvent to deliver to listeners
See Also: EventListenerList,

  Notifies all listeners that have registered interest for notification on this event type.

  Notifies all listeners that have registered interest for
notification on this event type.
Parameters:
- e - the ItemEvent to deliver to listeners
See Also: EventListenerList,

  Notifies all listeners that have registered interest for notification on this event type.

  Notifies all listeners that have registered interest for
notification on this event type. The event instance
is created lazily.

Returns the action command string for the button.

  Returns an array of all the action listeners registered on this DefaultButtonModel.

  Returns an array of all the action listeners
registered on this DefaultButtonModel.
Returns: all of this model's ActionListeners or an empty array if no action listeners are currently registered
Since: 1.4
See Also: DefaultButtonModel.addActionListener(java.awt.event.ActionListener), DefaultButtonModel.removeActionListener(java.awt.event.ActionListener),

  Returns an array of all the change listeners registered on this DefaultButtonModel.

  Returns an array of all the change listeners
registered on this DefaultButtonModel.
Returns: all of this model's ChangeListeners or an empty array if no change listeners are currently registered
Since: 1.4
See Also: DefaultButtonModel.addChangeListener(javax.swing.event.ChangeListener), DefaultButtonModel.removeChangeListener(javax.swing.event.ChangeListener),

  Returns the group that the button belongs to.

  Returns the group that the button belongs to.
Normally used with radio buttons, which are mutually
exclusive within their group.
Returns: the ButtonGroup that the button belongs to
Since: 1.3

  Returns an array of all the item listeners registered on this DefaultButtonModel.

  Returns an array of all the item listeners
registered on this DefaultButtonModel.
Returns: all of this model's ItemListeners or an empty array if no item listeners are currently registered
Since: 1.4
See Also: DefaultButtonModel.addItemListener(java.awt.event.ItemListener), DefaultButtonModel.removeItemListener(java.awt.event.ItemListener),

  Returns an array of all the objects currently registered as FooListeners upon this model.

  Returns an array of all the objects currently registered as FooListeners upon this model. FooListeners are registered using the addFooListener method.

You can specify the listenerType argument with a class literal, such as FooListener.class. For example, you can query a DefaultButtonModel instance m for its action listeners with the following code:

ActionListener[] als = (ActionListener[])(m.getListeners(ActionListener.class));

If no such listeners exist, this method returns an empty array.
Returns: an array of all objects registered as FooListeners on this model, or an empty array if no such listeners have been added
Parameters:
- listenerType - the type of listeners requested; this parameter should specify an interface that descends from java.util.EventListener
Throws:
- ClassCastException - if listenerType doesn't specify a class or interface that implements java.util.EventListener
Since: 1.3

Overridden to return null.

Indicates partial commitment towards triggering the button.

Indicates if the button can be selected or triggered by an input device, such as a mouse pointer.

Indicates if the button is pressed.

Indicates that the mouse is over the button.

Removes an ActionListener from the model.

Removes a ChangeListener from the model.
