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 DefaultListSelectionModel
instance m
for its list selection listeners
with the following code:
ListSelectionListener[] lsls = (ListSelectionListener[])(m.getListeners(ListSelectionListener.class));If no such listeners exist, this method returns an empty array.

this parameter should specify an interface
that descends from java.util.EventListener

listeners have been added

java.util.EventListenergetListSelectionListeners()public void setLeadAnchorNotificationEnabled(boolean flag)
isLeadAnchorNotificationEnabled()public boolean isLeadAnchorNotificationEnabled()
leadAnchorNotificationEnabled flag.
When leadAnchorNotificationEnabled is true the model
generates notification events with bounds that cover all the changes to
the selection plus the changes to the lead and anchor indices.
Setting the flag to false causes a narrowing of the event's bounds to
include only the elements that have been selected or deselected since
the last change. Either way, the model continues to maintain the lead
and anchor variables internally. The default is true.
Note: It is possible for the lead or anchor to be changed without a change to the selection. Notification of these changes is often important, such as when the new lead or anchor needs to be updated in the view. Therefore, caution is urged when changing the default value.

If the value at the anchor index is not selected, do the same thing in reverse selecting values in the old range and deslecting values in the new one.
Generate a single event for this change and notify all listeners. For the purposes of generating minimal bounds in this event, do the operation in a single pass; that way the first and last index inside the ListSelectionEvent that is broadcast will refer to cells that actually changed value because of this method. If, instead, this operation were done in two steps the effect on the selection state would be the same but two events would be generated and the bounds around the changed values would be wider, including cells that had been first cleared only to later be set.
This method can be used in the mouseDragged method
of a UI class to extend a selection.
