Class BrowserAdapter

java.lang.Object

com.webrenderer.swing.event.BrowserAdapter

All Implemented Interfaces:

BrowserListener, EventListener

public abstract class BrowserAdapter
extends Object
implements BrowserListener

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

Extend this class to create a BrowserEvent listener and override the methods for the events of interest. (If you implement the BrowserListener 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 require.)

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

An example of using a BrowserAdapter on a IBrowserCanvas called browser to listen for title change events can be achieved by:

 browser.addBrowserListener( new BrowserAdapter() {
     public void onTitleChange( BrowserEvent e ) {
         System.out.println( "Title Changed to: " + e.getTitle() );
     }
 });
