Class WindowAdapter

java.lang.Object
  com.webrenderer.event.WindowAdapter

All Implemented Interfaces:

java.util.EventListener, WindowListener

public abstract class WindowAdapter

extends java.lang.Object

implements WindowListener

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

Extend this class to create a WindowEvent listener and override the methods for the events of interest. (If you implement the WindowListener 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 addWindowListener method. When a browser event occurs, the relevant method in the listener object is invoked and the WindowEvent is passed to it.

Method Detail

onNewWindow

public void onNewWindow(WindowEvent e)

Description copied from interface: WindowListener

Invoked when a new window is requested.

Specified by:

onNewWindow in interface WindowListener

Parameters:

e - Event.
e.getPopupBrowser() returns the IBrowserCanvas to add to the UI.
e.getWidth() and e.getHeight() return the requested size for the popup, this may change later through a call from onWindowResize(WindowEvent).
When added to an IIEBrowserCanvas you must then add a listener for onWindowResize to size the frame.

onWindowDestroy

Invoked when a window destroyed. The web browser has been destroyed by a window.close(). Normal behaviour on this event is to close the frame (or tab) contianing the IBrowserCanvas.

public void onWindowResize(WindowEvent e)
