Examples of javax.swing.event.ChangeEvent

javax.swing.event.ChangeEvent
ChangeEvent is used to notify interested parties that state has changed in the event source.
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. Please see {@link java.beans.XMLEncoder}. @author Jeff Dinkins
