I have a custom class that extends the MovieClip class. The library linked mc, is an empty mc. The class uses the drawing API to create the visual content on the stage.

I am having issues defining MovieClip events. The constructor looks like:

```auto

public function Shape (target_mc:MovieClip, depth:Number, paramObj:Object) {
        name = Type + "_" + depth;
        __mc = this;
        __mc = target_mc.attachMovie ("Shape", name, depth);
       //do drawing API stuff with paramObj
}

```

then on the stage I am trying to do this:

```auto

var s:Shape = new Shape (some_mc, someDepth, {...});
s.onRelease = function () {
   trace ("released");
}

```

So I am not sure how to proceed. I was thinking about using a decorator pattern to somehow define the mc events, but I would assume there is something super simple that I am overlooking.

Any help is much appreciated. Thank you.
