I'm trying to start a page but would like to understand the use of the Stage.onResize method...

Is it supposed to work when the browser scale changes?

I'm coding:

Code:
Stage.scaleMode = "noScale";
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;
	prova_mc._xscale = 10;
	prova_mc._yscale = 10;
};
where prova_mc is just a circle clip on stage, but nothing happens if I resize my browser
