Need help with detecting window/browser resizes

If the browser is resized I need to be able to detect that and
resize my flash object accordingly, which I can handle that part.

I need help with being able to detect if the browser is resized
with some way to communicate that to flash and act on it.

I am using swfobject to display my flash object, I have tried a method of adding a javascript function for when the browser is resized(which I think may be the best method but I can't get flash to detect that variable if it changes... Maybe I need some sort of listener?) with no luck.

I will attach an image of my layout so you can see what im talking about. If this is not clear ask and I will explain a little more.

Also notice that I do not want to make this a fullscreen flash object, it has to be inside a DIV container which I will be able to set dynamic widths on if needed.

PHP Code:

---

var resizeObj = new Object();
resizeObj.onResize = function(){
    trace("new stage dim. : "+Stage.width+" x "+Stage.height);
}
Stage.addListener(resizeObj); 


---

but as you said it seems that you can workout the rest yourself- because even if you say

PHP Code:

---

Stage.scaleMode = "noScale" 


---

you still need to pinpoint the new absolute XY coordinate wich are shifted if you resize the flash movie- fullscreen or not doesn´t matter.

I got it all figured out, thank you.
