Flex/Actionscript 3 dynamic width/height change

Is it possible to dynamically (not in the project's options) change the dimensions of the stage by using ActionScript 3? I'd want to create a 400x300px loader, but I also want it to load animations that have bigger or smaller dimensions. I would then change the width and heigh开发者_如何学Got of the loader to make the loaded animations fit well.

Is there any way to do that?

Thanks.

<YourLoaderOrContainerWithAnimation top="0" bottom="0" left="0" right="0" width="100%" height="100%" minWidth="400" minHeight="300" maxWidth="400" maxHeight="300"/>

first of all use code.google.com/p/swfobject instead of embed tag, and yes you can directly change sizes like this.width=width_from_js; but as I remember swfobject will allow you to do this in raw js, just check it and let us know. :) thanks
