(AS3)Load library item with UIloader and Progrees Bar components

[freshly]

Hi Everyone,

I have a set up that loads an external image using the Progress Bar and UILoader components. How may I adapt this code to load library item instead?

//LOADER

var imageURL:String = "content1";

var imageURLRequest = new URLRequest(imageURL);

uiLoader.scaleContent = false;
uiLoader.load(imageURLRequest);

progressBar.source = uiLoader;
progressBar.addEventListener(ProgressEvent.PROGRESS, progressHandler);
progressBar.addEventListener(Event.COMPLETE, completeHandler);

function progressHandler(event:ProgressEvent):void
{

	status_txt.text = int(event.currentTarget.percentComplete) + "%";

}

function completeHandler(event:Event):void
{

	progressBar.removeEventListener(ProgressEvent.PROGRESS, progressHandler);
	progressBar.removeEventListener(Event.COMPLETE, completeHandler);
	removeChild(progressBar);
	status_txt.text = "";

}
//LOADER

Any help is much appreciated

Ok I managed to load the movie clip into my UILoader but I can't get the Progress Bar to kick in. Can someone point me into the right direction, please and thanks:-)

//LOADER

var imageLoad:MovieClip = new content1();

uiLoader.addChild(imageLoad);
uiLoader.scaleContent = false;

progressBar.source = uiLoader;
progressBar.addEventListener(ProgressEvent.PROGRESS, progressHandler);
progressBar.addEventListener(Event.COMPLETE, completeHandler);

function progressHandler(event:ProgressEvent):void
{

	//status_txt.text = int(event.currentTarget.percentComplete) + "%";

}

function completeHandler(event:Event):void
{

	progressBar.removeEventListener(ProgressEvent.PROGRESS, progressHandler);
	progressBar.removeEventListener(Event.COMPLETE, completeHandler);
	removeChild(progressBar);
	//status_txt.text = "";

}

//LOADER
