Loading Bar

programming flash

Hi,

I have a movie that loads flv videos from an xml file. They can take a while to load so need to add a loading bar. Not sure what I need to add to the following code so any help would be very much appreciated …

package {
	import flash.display.MovieClip;
	import flash.net.URLLoader;
	import flash.net.URLRequest;
	import flash.events.Event;
	import flash.events.MouseEvent;
	import fl.controls.listClasses.CellRenderer;
	import fl.controls.ScrollBarDirection;
	import flash.display.StageScaleMode; 
	import flash.display.StageAlign;
	
	public class videos extends MovieClip {
		private var xmlLoader:URLLoader;
		
		public function videos():void {
			
			// Load the playlist file, then initialize the media player.
			xmlLoader = new URLLoader();
			xmlLoader.addEventListener(Event.COMPLETE, initMediaPlayer);
			xmlLoader.load(new URLRequest("http://staging.ph-creative.com/sites/hip/res/media/xml/playlist.xml"));
			
			// Format the tileList, specify its cellRenderer class.
			control.tileList.setSize(138, 108);
			control.tileList.columnWidth = 46;
			control.tileList.rowHeight = 54;
			control.tileList.setStyle("cellRenderer", Thumb);
		}
		
		public function initMediaPlayer(event:Event):void {
			
			var myXML:XML = new XML(xmlLoader.data);
			var item:XML;
			for each(item in myXML.vid4) { // populate playlist.
				// Get thumbnail value and assign to cellrenderer.
				var thumb:String;
				if(item.hasOwnProperty("@thumb")>0) thumb = item.@thumb;
				// Send data to tileList.
				control.tileList.addItem({label:item.attribute("desc").toXMLString(), 
				data:item.attribute("src").toXMLString(),
				source:thumb});;
			}
			
			// Select the first video.
			control.tileList.selectedIndex = 0;
			// Listen for item selection.
			control.tileList.addEventListener(Event.CHANGE, listListener);
			// And automatically load it into myVid.
			myVid.source = control.tileList.selectedItem.data;
		}

		
		// Detect when new video is selected, and play it
		function listListener(event:Event):void {
			
			myVid.play(event.target.selectedItem.data);
		}
	}
}
