Можно как-то так:

package  
{
	import flash.display.Sprite;
	import flash.events.Event;
	import flash.events.MouseEvent;
 
	/**

	public class DragBlock extends Sprite 
	{
		static public const HORIZONTAL:String = "horizontal";
		static public const VERTICAL:String = "vertical";
 
		private var orient:String;
 
		public function DragBlock(w:Number,h:Number,orient:String) 
		{
			this.orient = orient;
 
			graphics.beginFill(0xCC00CC);
			graphics.drawRect(0, 0, w, h);
			graphics.endFill();
 
			addEventListener(Event.ADDED_TO_STAGE, addedToStage);
			addEventListener(Event.REMOVED_FROM_STAGE, removedFromStage);
		}
 
		private function removedFromStage(e:Event):void 
		{
			removeEventListener(Event.REMOVED_FROM_STAGE, removedFromStage);
 
			removeEventListener(MouseEvent.MOUSE_DOWN, mouseDown);
