Method Summary

void	addListDataListener(ListDataListener l) Adds a listener to the list that's notified each time a change to the data model occurs.
protected void	fireContentsChanged(Object source, int index0, int index1) AbstractPropertyGridModel subclasses must call this method after one or more elements of the list change.
protected void	fireIntervalAdded(Object source, int index0, int index1) AbstractPropertyGridModel subclasses must call this method after one or more elements are added to the model.
protected void	fireIntervalRemoved(Object source, int index0, int index1) AbstractPropertyGridModel subclasses must call this method after one or more elements are removed from the model.
ListDataListener[]	getListDataListeners() Returns an array of all the list data listeners registered on this AbstractPropertyGridModel.
EventListener[]	getListeners(Class listenerType) Returns an array of all the objects currently registered as FooListeners upon this model.
void	removeListDataListener(ListDataListener l) Removes a listener from the list that's notified each time a change to the data model occurs.

Method Detail

addListDataListener

public void addListDataListener(ListDataListener l)

Adds a listener to the list that's notified each time a change to the data model occurs.

Specified by:

addListDataListener in interface PropertyGridModel

Parameters:

l - the ListDataListener to be added

removeListDataListener

public void removeListDataListener(ListDataListener l)

Removes a listener from the list that's notified each time a change to the data model occurs.

Specified by:

removeListDataListener in interface PropertyGridModel

Parameters:

l - the ListDataListener to be removed

getListDataListeners

public ListDataListener[] getListDataListeners()

Returns an array of all the list data listeners registered on this AbstractPropertyGridModel.

Returns:

all of this model's ListDataListeners, or an empty array if no list data listeners are currently registered

fireContentsChanged

protected void fireContentsChanged(Object source,
                                   int index0,
                                   int index1)

AbstractPropertyGridModel subclasses must call this method after one or more elements of the list change. The changed elements are specified by the closed interval index0, index1 -- the endpoints are included. Note that index0 need not be less than or equal to index1.

Parameters:

source - the PropertyGridModel that changed, typically "this"

index0 - one end of the new interval

index1 - the other end of the new interval

EventListenerList, DefaultPropertyGridModel

fireIntervalAdded

protected void fireIntervalAdded(Object source,
                                 int index0,
                                 int index1)

AbstractPropertyGridModel subclasses must call this method after one or more elements are added to the model. The new elements are specified by a closed interval index0, index1 -- the enpoints are included. Note that index0 need not be less than or equal to index1.

Parameters:

source - the PropertyGridModel that changed, typically "this"

index0 - one end of the new interval

index1 - the other end of the new interval

See Also:

EventListenerList, DefaultPropertyGridModel

fireIntervalRemoved

protected void fireIntervalRemoved(Object source,
                                   int index0,
                                   int index1)

AbstractPropertyGridModel subclasses must call this method after one or more elements are removed from the model. The new elements are specified by a closed interval index0, index1, i.e. the range that includes both index0 and index1. Note that index0 need not be less than or equal to index1.

Parameters:

source - the PropertyGridModel that changed, typically "this"

index0 - one end of the new interval

index1 - the other end of the new interval

EventListenerList, DefaultPropertyGridModel

getListeners

public EventListener[] getListeners(Class 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 list model m for its list data listeners with the following code:

ListDataListener[] ldls = (ListDataListener[])(m.getListeners(ListDataListener.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
