Full Screen Flash preserving location of movieclips

Let's say we have a bar stretching across the whole top of the screen with the following code:

import flash.display.Sprite;

import flash.display.StageAlign;

import flash.display.StageScaleMode;

import flash.events.Event;

stage.scaleMode = StageScaleMode.NO_SCALE;

stage.align = StageAlign.TOP_LEFT

stage.addEventListener(Event.RESIZE, resizeHandler);

//function to handle background image resize.

function setBackground() {

this.width = stage.stageWidth;

}

setBackground();

function resizeHandler(event:Event):void {

setBackground();

};
