addListener (Stage.addListener method)

public static addListener(listener:Object) : Void

Detects when a SWF file is resized (but only if Stage.scaleMode = "noScale"). The

addListener() method doesn't work with the default movie clip scaling setting (showAll)

or other scaling settings (

exactFit and noBorder).

To u se

addListener(), you must first create a listener object. Stage listener objects receive

notification from

Stage.onResize.

Availability: ActionScript 1.0; Flash Lite 2.0

Parameters

listener:Object - An object that listens for a callback notification from the

Stage.onResize event.

Example

This example creates a new listener object called stageListener. It then uses

stageListener to call onResize and define a function that will be called when onResize is

triggered. Finally, the code adds the

stageListener object to the callback list of the Stage

object. Listener objects allow multiple objects to listen for resize notifications.

this.createTextField("stageSize_txt", this.getNextHighestDepth(), 10, 10,

100, 22);

var stageListener:Object = new Object();

stageListener.onResize = function() {

stageSize_txt.text = "w:"+Stage.width+", h:"+Stage.height;

};

Stage.scaleMode = "noScale";

Stage.addListener(stageListener);
