Declaring Callback Functions in CSXS Extension (for Flash)

Question

A few features offered in Flash's scripting language are handful of event listeners you can attach to Flash that will in tern call any associated JSFL function you've attached to them while Flash is running. You can then listen for events like "documentNew", "documentChange", "mouseMove", etc.
JSFL Code Would Look Something Like this:
fl.addEventListener("documentOpened", myDocumentOpenedHandler);
function myDocumentOpenedHandler()
     swfObject.call("callBackFunction_InsideFlashPanel");
My swfPanel registers a callback function, "callBackFunction_InsideFlashPanel" which would handle the event inside the panel.
This is a way of ensuring my Panel is notified when a change takes place in Flash.
Adobe has an article about it here:

My question is, how should this be implemented in a CS Extension using the CS SDK?
Thanks,

Answer 1

Right. The whole point of the question is if is possible to
dynamically declare functions for use as callbacks.
For example, in the standard loading functions, you register
a callback like this:
var load:Loader = new Loader();
var req:URLRequest = new URLRequest(swf);
load.contentLoaderInfo.addEventListener(Event.COMPLETE,
swfloadcallback);
load.load(req);
function swfloadcallback(e:Event):void
The problem with the standard callback function is that I
can't add additional arguments to it. For example, I couldn't have
swfloadcallback take in an additional argument (for example the
index of the swf I'm trying to load). What I'm wondering is if in
actionscript 3 it's possible to dynamically declare callbacks such
that I only have to write the code once, but in essence I am adding
additional parameters to the callback.
Hence the example I listed above. What I was trying to
accomplish there was basically dynamically creating callbacks that
understood which index to insert the loaded image into. But clearly
that example doesn't work.
