Hi Andew,
Just a month ago Jason posted a very very usefull note on how to
write custom events.
See below:
Here is how you write a custom event:
package
{
import flash.events.Event;
public class MyEvent extends Event
{
public static var SOUND_REQUESTED:String =
"sound_requested";
public function MyEvent(type:String,
bubbles:Boolean=false, cancelable:Boolean=false)
{
super(type, bubbles, cancelable);
}
public override function clone():Event
{
return new MyEvent(type, bubbles, cancelable);
}
public override function toString():String
{
return formatToString("MyEvent", "type",
"bubbles", "cancelable", "eventPhase");
}
}
}
Here is how you would dispatch that event with bubbling:
dispatchEvent(new MyEvent(MyEvent.SOUND_REQUESTED, true));
Here is how you would listen for it and handle it anywhere in the
display chain:
addEventListener(MyEvent.SOUND_REQUESTED, onSoundRequested);
function onSoundRequested(event:MyEvent):void
{
//Code to play sound here.
}

Event extends Object, right?
Event is not a dynamic class. In AS3, you can only add properties to
dynamic classes. So, as everyone else has mentioned, you have to
extend Event to create a custom event class. Don't forget to override
the clone method and create a new event!
