public class OptionEvent

extends java.awt.AWTEvent

A semantic event which indicates that a Option-defined action occured. This high-level event is generated by an Option component when an action occurs (such as a key insertion). The event is passed to every OptionListener object that registered to receive such events using the Option's addOptionListener method.

The object that implements the OptionListener interface gets this OptionEvent when the event occurs. The listener is therefore spared the details of processing individual selection, and can instead process a "meaningful" (semantic) event like "key inserted".
