How to trigger an event with ActionScript 3.0 when the sizes of a swf’s stage are modified

This is very useful when you try to create a “liquid” flash application.

ActionScript 3.0 code:



//The next 2 lines are not mandatory. 
//Use them if you whant to keep the original sizes.
stage.scaleMode = StageScaleMode.NO_SCALE;
stage.align = StageAlign.TOP_LEFT; // Other values: 
//TOP, BOTTOM, LEFT, RIGHT, TOP_RIGHT
// BOTTOM_LEFT, BOTTOM_RIGHT 

stage.addEventListener(Event.RESIZE, resizeHandler);

function resizeHandler(event:Event):void 
{
        trace(stage.stageWidth);
        trace(stage.stageHeight);
        trace("An event has been triggered.");
}
