Inspectible from Components Pannel?

I was just wondering how to make the properties of a class viewable in the Components Panel. This way, someone who doesn’t program can set properties of a MovieClip by clicking on it.

This is where I’m at so far:

package
{
    import flash.display.MovieClip;

 public class Rotator extends MovieClip 
 {
    
     private var _rotationSpeed:Number;
    
 
     public function Rotator():void
    {
     
    }
    
    [Inspectable (defaultValue=0)]
    public function set rotationSpeed(speed:Number):void
    {
        _rotationSpeed = speed;
    }

 }
}
