java.lang.Object
java.util.EventObject
javax.swing.event.ListSelectionEvent
- All Implemented Interfaces:
Serializable
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 decent
ListSelectionModel implementation
will keep the range as small as possible. ListSelectionListeners will
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.beans package.
