	public class LoadButton extends Sprite 
	{
		public var Save;
		public function LoadButton(x:uint,save:String,url:String) 
		{
			var button:CustomSimpleButton = new CustomSimpleButton(url);
			button.x = x;
			Save = save;
			addChild(button);
		}
	}
}

		hitTestState.x = -(sizew / 4);
		hitTestState.y = hitTestState.x;
		useHandCursor  = true;
	}
}

class ButtonDisplayState extends Shape 
{

		draw(url);

		var image:Bitmap;
		var uri = new URLRequest(url);
		myLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, function(e:Event)
		{
			image = new Bitmap(e.target.content.bitmapData);

			graphics.beginBitmapFill(image.bitmapData);
			graphics.drawRect(0, 0, 100, 88);
			graphics.endFill();
		});
		myLoader.load(uri);
