public abstract class OptionAdapter

extends java.lang.Object

implements OptionListener

An abstract adapter class for receiving option events. The methods in this class are empty. This class exists as convenience for creating listener objects.

Extend this class to create a OptionEvent listener and override the methods for the events of interest. (If you implement the OptionListener interface, you have to define all of the methods in it. This abstract class defines null methods for them all, so you can only have to define methods for events you care about.)

Create a listener object using your class and then register it with a component using the OptionContainer's addOptionListener method. When the option's state changes, the relevant method in the listener object is invoked, and the ComponentOption is passed to it.
