FLASH® LITE™ 2.x - Adobe Help and Support

Invoked when a movie clip receives input focus. The oldFocus parameter is the object that
loses the focus. For example, if the user presses the Tab key to move the input focus from a
movie clip to a text field, oldFocus contains the movie clip instance.
If there is no previously focused object, oldFocus contains a null value.
You must define a function that executes when the event handler in invoked. You can define
the function on the Timeline or in a class file that extends the MovieClip class or is linked to
a symbol in the library.
Parameters
oldFocus:Object - The object to lose focus.
Example
The following example displays information about the movie clip that receives input focus,
and the instance that previously had focus. Two movie clips, called my_mc and other_mc are
on the Stage. Add the following ActionScript to your AS or FLA document:
my_mc.onRelease = Void;
other_mc.onRelease = Void;
my_mc.onSetFocus = function(oldFocus) {
trace("onSetFocus called, previous focus was: "+oldFocus);
}
When you press the Tab key between the two instances, information is displayed in the
Output panel.

onUnload = function() {}
Invoked in the first frame after the movie clip is removed from the Timeline. Flash processes
the actions associated with the onUnload event handler before attaching any actions to the
affected frame. You must define a function that executes when the event handler is invoked.
You can define the function on the Timeline or in a class file that extends the MovieClip class
or is linked to a symbol in the library.
Example
The following example defines a function for the MovieClip.onUnload method that sends a
trace() action to the Output panel:
