I have a AS3 class which extends movieClip with a dynamic image, how to make this image draggable?

I need to make an item draggable (dragable?) Sorry if my terminology is not right!

I have a class where I will store variable and do calculations:

package Classes
{
    import flash.display.*;
    import flash.events.*;
    import flash.net.*;

    public class PrintItem extends MovieClip
    {     
        public var imageLoader:Loader;

        public function PrintItem()
        {

        }

        public function loadImage(url:String):void
        {
            imageLoader = new Loader();
            imageLoader.load(new URLRequest(url));
        }
    }
} 

I create a new instance of the class, I pass it an URL in loadImage and I add it to the canvas like this:

var myItem:PrintItem = new PrintItem();
myItem.loadImage("pic.jpg");
this.addChild(myItem.imageLoader);
myItem.imageLoader.x = 50;
myItem.imageLoader.y = 50;
myItem.imageLoader.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);
myItem.imageLoader.addEventListener(MouseEvent.MOUSE_UP, dropIt);

But there I am stuck. I need to make this item draggable and write the pickUp and dropIt functions. event.target.startDrag(false); doesn't work (Loader isn't draggable) and event.target.parent.startDrag(false); doesn't work as the whole stage becomes draggable! HELP! Is it because only th开发者_Go百科e Loader is added to the stage?

Ok. I know it has only been a few minutes, but I have found the answer. Writing it down here cleared it in my head. Here's what worked for me in case it helps anybody else:

First, I added the Loader image as a child to the class like this:

public function loadImage(url:String):void
{
    imageLoader = new Loader();
    imageLoader.load(new URLRequest(url));
    this.addChild(imageLoader); // IMPORTANT!
    this.mouseChildren = false;
    this.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);
    this.addEventListener(MouseEvent.MOUSE_UP, dropIt);
}

And then I only had to add the class to the stage, not the loader:

this.addChild(myItem);

Back to the class, I added this:

public function pickUp(event:MouseEvent):void
{
  trace("Pickup");
  this.startDrag(false);
}
public function dropIt(event:MouseEvent):void
{
  this.stopDrag();
  trace("X = " + event.target.x + " Y = " + event.target.y); // Just to help me
}

Et voila! It worked!
