- All Implemented Interfaces:
- Serializable
public class ListSelectionEvent extends EventObject
An event that characterizes a change in selection. The change is limited to a a single inclusive interval. The selection of at least one index within the range will have changed. A decentListSelectionModelimplementation will keep the range as small as possible.ListSelectionListenerswill generally query the source of the event for the new selected status of each potentially changed row.Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the
java.beanspackage. Please seeXMLEncoder.- See Also:
