Class ChangeEvent

java.lang.Object
  java.util.EventObject
      com.elegantj.gauges.ChangeEvent

All Implemented Interfaces:

java.io.Serializable

public class ChangeEvent

extends java.util.EventObject

The ChangeEvent is generated by a Gauge (such as a DialGauge) when the Gauge-specific action occurs (such as value changed or zone changed). The event is passed to every ChangeListener object that registered to receive such events using the gauge's addChangeListener method. The object that implements the ChangeListener interface gets this ChangeEvent when the event occurs.
