  • 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
