  java.util.EventObject
      org.jdesktop.dataset.event.RowChangeEvent

All Implemented Interfaces:

java.io.Serializable

public class RowChangeEvent
extends java.util.EventObject

A RowChangeEvent is broadcast by a data table to listeners as rows are changed, on a per-row basis. An EventType enumeration identifies the type of change. A change to a column's value which affects row status results in two events being broadcast, one for the column change and one for the row status change.
