The whole deal with event dispatching is that you listen for certain event to
take place from the outside, not from the inside.
The way you have it now, you're not really making use of event dispatching
(well only in an weird way), but it's more like adding
(overriding) a method of the class.
instance.onEvent=function(){}
You should do something like this:
import mx.utils.Delegate;
function eventHandler(o:Object) {
trace("EVENT ::: eventHandler");
}
var etry:EventTry=new EventTry();
etry.addEventListener("eventName", Delegate.create(this, this.eventHandler));
The only problem you might then run into is that if you try to dispatch an
event in the constructor of the class (or the init method
called from the constructor) is that the EventDispacher mixin has not taken
place yet. There's a delay (1 frame?) you have to take
into account. You can get around that by using a setInterval or if the class
extends the MovieClip class, by defining an onLoad
method in the class and dispatch the event there.
