Overriding UIComponent's height, width setters..

Question

I'm writing a custom UIComponent, and would like to perform some custom actions when the height/width are set in mxml.
e.g. the mxml will have something like
<custom:MyComp id="mcid" width="30" height="40".......></custom:MyComp>
and I'd like to write something such as this in  MyComp.as
public override function set width (x:Number):void {
       super.width = x;
       // ... followed by my custom actions
This is probably not the correct direction. The code written in this way results in a problem whereby the setter get called twice (the second time, it is called automatically via the property watcher as well --- with values that are not right). What's the correct way of implementing this? Thanks in advance.

Answer 1

Thanks. I tried that earlier, but it didn't seem to work for me. There seems to be an easier way I just found, but don't know if that's right.
In your MyComp constructor you can add a listener:
public function MyComp () {
   super ();
   addEventListener (ResizeEvent.RESIZE, rsHandler);
private function rsHandler (rs:ResizeEvent):void {
   // custom code
Of course, I guess this won't work if I want to do different actions for width, and a different action for height setter.
