Constructor Detail

• DefaultSingleSelectionModel

  public DefaultSingleSelectionModel()

Method Detail

• getSelectedIndex

  public int getSelectedIndex()

  Description copied from interface: SingleSelectionModel
  Returns the model's selection.

  Specified by:

  getSelectedIndex in interface SingleSelectionModel

  Returns:

  the model's selection, or -1 if there is no selection

  See Also:

  SingleSelectionModel.setSelectedIndex(int)

• setSelectedIndex

  public void setSelectedIndex(int index)

  Description copied from interface: SingleSelectionModel
  Sets the model's selected index to index. Notifies any listeners if the model changes

  Specified by:

  setSelectedIndex in interface SingleSelectionModel

  Parameters:

  index - an int specifying the model selection

  See Also:

  SingleSelectionModel.getSelectedIndex(), SingleSelectionModel.addChangeListener(javax.swing.event.ChangeListener)

• clearSelection

  public void clearSelection()

  Description copied from interface: SingleSelectionModel
  Clears the selection (to -1).

  Specified by:

  clearSelection in interface SingleSelectionModel

• isSelected

  public boolean isSelected()

  Description copied from interface: SingleSelectionModel
  Returns true if the selection model currently has a selected value.

  Specified by:

  isSelected in interface SingleSelectionModel

  Returns:

  true if a value is currently selected

• addChangeListener

  public void addChangeListener(ChangeListener l)

  Adds a ChangeListener to the button.

  Specified by:

  addChangeListener in interface SingleSelectionModel

  Parameters:

  l - the ChangeListener to add

• removeChangeListener

  public void removeChangeListener(ChangeListener l)

  Removes a ChangeListener from the button.

  Specified by:

  removeChangeListener in interface SingleSelectionModel

  Parameters:

  l - the ChangeListener to remove

• getChangeListeners

  public ChangeListener[] getChangeListeners()

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

  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)

• fireStateChanged

  protected void fireStateChanged()

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

  See Also:

  EventListenerList

• getListeners

  public <T extends EventListener> T[] getListeners(Class<T> listenerType)

  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 DefaultSingleSelectionModel instance m for 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.

  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 listenerType doesn't specify a class or interface that implements java.util.EventListener

  Since:

  1.3
