Flash Player 6.
my_mc.onLoad
None.
Nothing.
Event handler; invoked when the movie clip is instantiated and appears in the Timeline.
You must define a function that executes when the event handler is invoked.
The following example defines a function for the MovieClip.onLoad handler that sends a trace action to the Output window:
my_mc.onLoad = function () {
trace ("onLoad called");
};
