Progress bar question

Question

i am loading a .jpg into a holder movie clip. easy enough.
but i want a progress bar that will show the progress then go away
when it is complete. im trying to use an if statement to get it to
disappear, but i dont know what i should put in the if part. here
is my code...
one.addEventListener(MouseEvent.MOUSE_DOWN,
mouseDownHandler);
function mouseDownHandler(event:MouseEvent):void {
var pictLdr:Loader = new Loader();
var pictURL:String = "images/1.jpg"
var pictURLReq:URLRequest = new URLRequest(pictURL);
pictLdr.load(pictURLReq);
holder.addChild(pictLdr);
//loading bar
var dataPath:String = "images/1.jpg";
var loader:URLLoader = new URLLoader();
loader.load(new URLRequest(dataPath));
var pb:ProgressBar = new ProgressBar();
pb.source = loader;
addChild(pb);
pb.x = 100
pb.y = 200
if (??????? == ????) {
removeChild(pb);
any suggestions????

Answer 1

well i figured it out....so ill answer my own question in
case it can help someone else. i didnt use an if statement...i used
a function statement instead. heres what it looks like...
one.addEventListener(MouseEvent.MOUSE_DOWN,
mouseDownHandler);
function mouseDownHandler(event:MouseEvent):void {
var pictLdr:Loader = new Loader();
var pictURL:String = "images/1.jpg"
var pictURLReq:URLRequest = new URLRequest(pictURL);
pictLdr.load(pictURLReq);
holder.addChild(pictLdr);
//loading bar
var dataPath:String = "images/1.jpg";
var loader:URLLoader = new URLLoader();
loader.load(new URLRequest(dataPath));
var pb:ProgressBar = new ProgressBar();
pb.source = loader;
addChild(pb);
pb.x = 100
pb.y = 200
//remove bar
pb.addEventListener(Event.COMPLETE, completeHandler);
function completeHandler(event:Event):void {
pb.removeEventListener(Event.COMPLETE, completeHandler);
removeChild(pb);
hope that can help someone
