Class JavascriptAdapter

java.lang.Object

com.webrenderer.swing.event.JavascriptAdapter

All Implemented Interfaces:

JavascriptListener, EventListener

public abstract class JavascriptAdapter
extends Object
implements JavascriptListener

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

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

Create a listener object using the extended class and then register it with a browser using the browser's addJavascriptListener method. When a Javascript event occurs, the relevant method in the listener object is invoked and the JavascriptEvent is passed to it.
