[AS3]using buttons to load external swf

Hi, just started using AS3 and i would like some help.

I have four button on my main movie, which basically will load an external swf when pressed. Right now, i'm able to load the first movie directly using this code

Code:

---

prBut.addEventListener(MouseEvent.CLICK, onClick);
srBut.addEventListener(MouseEvent.CLICK, onClick);
tm.addEventListener(MouseEvent.CLICK, onClick);
conBut.addEventListener(MouseEvent.CLICK, onClick);


function onClick(e:MouseEvent):void
{
        trace(e.target.name + "has been pressed");
}

var holder:MovieClip;
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);
loader.load(new URLRequest("home.swf"));

function onComplete(e:Event):void
{       
        holder = MovieClip(e.target.content);
        holder.x = 2;
        holder.y = 176;
        addChild(holder);
}

Now, how do i use buttons to load the movies?

Can someone help me plz

What do you mean by load movies? If you want the images to be loaded on clicking the button call loader.load in onClick. Also for 4 buttons you can right 4 onClicks and load diff images accordingly.

Do you have any working example i can refer to? AS2 was easy with the MovieClipLoader. But i must AS3 is very different
