Create an event listener object. As with the other types of listener object discussed in this book, there are many different types of objects that could be used, but for the purposes of keeping the example simple and functional, I will use an instance of the Object class. Therefore, to create the object, use the following code as an example:

	var oLoadedListener:Object = new Object();

When the content has loaded, the ProgressBar will dispatch a complete event and the listener object's complete( ) method is automatically called. Therefore, you'll want to add a complete( ) method to the listener. The following code shows how to add the method to the listener object (we'll look at the code that goes within the method in the next step):

	oLoadedListener.complete = function(oEvent:Object):Void {
	};

Within the complete( ) method, set the ProgressBar instance's visible property to false. You can reference the ProgressBar instance in one of several ways. The complete( ) method is passed a parameter that has a reference to the ProgressBar. You can retrieve that reference by way of the target property of that parameter. Therefore, you should define the code within the complete( ) method as follows. (The code shown includes the code from the previous step, with the new code shown in boldface.)

	oLoadedListener.complete = function(oEvent:Object):Void {

	  oEvent.target.visible = false;
	};

The remaining step is to add the listener object as a listener for the ProgressBar instance. You should call the addEventListener( ) method from the ProgressBar instance in order to do that. Assuming that you have named the ProgressBar instance pbIndicator, then you can use the following code to register a listener object named oLoadedListener to listen for the complete event.

	pbIndicator.addEventListener("complete", oLoadedListener); 

If you haven't already, complete steps 1 through 5 from the discussion of using MovieClipLoader to monitor load progress in Recipe 16.4.

Add an onLoadComplete( ) method to the listener object. The onLoadComplete( ) method is automatically called when the content has loaded completely. The following code shows the basic method declaration (I'll discuss the content of the method in the next step):

	oMlListener.onLoadComplete = function(mContent:MovieClip):Void {
	};

Within the onLoadComplete( ) method definition, set the _visible property to false for any and all load indicator movie clips and/or text fields that you have used. For example, if you have a load indicator bar movie clip named mcLoadIndicator and a text field named tLoadIndicatorLabel, than you can use the following onLoadComplete( ) declaration (new code shown in boldface):

	oMlListener.onLoadComplete = function(mContent:MovieClip):Void {

	  mLoadIndicator._visible = false
	  tLoadIndicatorLabel._visible = false;
	};
