ActionScript 2.0 Language Reference - Adobe Help and Support

The value for target_mc identifies the movie clip for which this call is being made. This is
useful when you are loading multiple files with the same set of listeners.
Note: If you attempt to use onLoadProgress in test mode with a local file that resides on
your hard disk, it does not work properly because, in test mode, Flash Player loads local files
in their entirety.
Availability: ActionScript 1.0; Flash Player 7
Parameters
target_mc:MovieClip [optional] - A movie clip loaded by the
MovieClipLoader.loadClip() method.
loadedBytes:Number - The number of bytes that had been loaded when the listener was
invoked.
totalBytes:Number - The total number of bytes in the file being loaded.
Example
The following example creates a movie clip, a new MovieClipLoader instance, and an
anonymous event listener. It periodically outputs the progress of a load and finally provides
notification when the load is complete and the asset is available to ActionScript.
var container:MovieClip = this.createEmptyMovieClip("container",
this.getNextHighestDepth());
var mcLoader:MovieClipLoader = new MovieClipLoader();
var listener:Object = new Object();
listener.onLoadProgress = function(target:MovieClip, bytesLoaded:Number,
bytesTotal:Number):Void {
trace(target + ".onLoadProgress with " + bytesLoaded + " bytes of " +
bytesTotal);
}
listener.onLoadInit = function(target:MovieClip):Void {
trace(target + ".onLoadInit");
}
mcLoader.addListener(listener);
mcLoader.loadClip("http://www.w3.org/Icons/w3c_main.png", container);
If your SWF file includes a version 2 component, use the version 2 component's
DepthManager class instead of the MovieClip.getNextHighestDepth() method, which is
used in this example.
