Ross,

The addEventListener would be on the instance of your "different class than the 
HTMLLoader".

myOtheraClass.addEventListener(MyCustomEventClass.MYCUSTOMEVENT, 
onMyCustomEvent)

Make sense?

Thanks Jason... Let me ask one question to try to clarify this for me.  If I 
have the dispatchEvent that broadcasts the URL of my HTLMLoader in a 
onLoadComplete function and I want to listen for that event in a different 
class (for example I want to put the URL in a textbox that is created in a 
different class than the HTMLLoader) where would I put the addEventListener?  
I'm not sure why my head is not wrapping around this, but thanks for all your 
help.

Ross

To add on to David's fine reply, Ross, you're close, but not quite - this is 
how I write custom events, I think you'll want to do something like this 
instead - this works great for me:

To write the event:

package events
{
        import flash.events.Event;

        public class MyEvent extends Event
        {
                public static var MYEVENT1:String = "myEvent1";  
                public static var MYEVENT2:String = "myEvent2";
                
                public function MyEvent(type:String, bubbles:Boolean = false, 
cancellable:Boolean = false ) 
                {
                        super(type, bubbles, cancelable);
                }
                
        }
        
}

Then to dispatch:

import events.MyEvent;

dispatchEvent(new MyEvent(MyEvent.MYEVENT2, false, true));


Then to listen and react to dispatch:

myObject.addEventListener(MyEvent.MYEVENT2, onMyEvent2)

public function onMyEvent2(event:MyEvent):void
{
        Trace("myEvent2 heard!");
}

An event is just a message object.  Just because one gets created
successfully does not mean it is being delivered.  dispatchEvent() is a
method of the EventDispatcher class, which is a superclass of many classes,
including DisplayObject.  You need to listen for the event (with
addEventListener()) on the same EventDispatcher where the event was
dispatched. (Except in the case of events that bubble, but that's another
topic.)

For example:

public class MyWindowHolder extends Sprite {
  public function init(): void {
    var a: MyWindow = new MyWindow();
    a.addEventListener( MyEvent.EXCLAMATION, onExclamation );
  }

  private function onExclamation( event: MyEvent ): void {
    trace("ouch!");
  }
}

public class MyWindow extends Sprite {
  private function injury(): void {
    this.dispatchEvent( new MyEvent( MyEvent.EXCLAMATION ));
  }
}

Hope this helps,
Dave
