onLoadStart = function([target_mc]) {}

Invoked when a call to MovieClipLoader.loadClip() has successfully begun to download a file. Call this listener on a listener object that you add using MovieClipLoader.addListener().

The value for target_mc identifies the movie clip this call is being made for. This parameter is useful if you are loading multiple files with the same set of listeners.

Parameterstarget_mc: MovieClip [optional] A movie clip loaded by a MovieClipLoader.loadClip() method.

Parameters

target_mc: [optional] - A movie clip loaded by a MovieClipLoader.loadClip() method.

Example

The following example loads an image into a movie clip instance called image_mc. The onLoadInit and onLoadComplete events are used to determine how long it takes to load the image. This information appears in a text field called timer_txt.

this.createEmptyMovieClip("image_mc", this.getNextHighestDepth());
var mclListener:Object = new Object();
mclListener.onLoadStart = function(target_mc:MovieClip) {
    target_mc.startTimer = getTimer();
};
mclListener.onLoadComplete = function(target_mc:MovieClip) {
    target_mc.completeTimer = getTimer();
};
mclListener.onLoadInit = function(target_mc:MovieClip) {
    var timerMS:Number = target_mc.completeTimer-target_mc.startTimer;
    target_mc.createTextField("timer_txt", target_mc.getNextHighestDepth(), 0, target_mc._height, 
target_mc._width, 22);
    target_mc.timer_txt.text = "loaded in "+timerMS+" ms.";
};
var image_mcl:MovieClipLoader = new MovieClipLoader();
image_mcl.addListener(mclListener);
image_mcl.loadClip("http://www.helpexamples.com/flash/images/image1.jpg", image_mc);
