Classes and XML.onLoad

[Brucebannor]

I'm making a rather large class for a project. So keep in mind this is all in a class file, thus my scope issue. I know I need to pass the onLoad the instance of the class. I would normally just pass it thru the function. ie
dr_xml.onLoad = function(thisObj){} but this is reserved for whether it has loaded correcty and will rewrite the value to true / false. Any idea how to get my thisObj to be visible?

I also tried to overLoad the parameters of onLoad, so it would set the first to true / false, then pass my thisObj to no avail.

function myFunction()
{
  trace(thisObj); // traces my Instance
  dr_xml = new XML(); 
  dr_xml.onLoad = function ()
  {
     trace(thisObj); // undefined
     processXML(dr_xml);
  }

}

function processXML()
{
    // yadda yadda
}

use Delegate..

//...
dr_xml.onLoad = mx.utils.Delegate.create(this,classXmlLoad);
//...
function classXmlLoad() 
{
    trace(thisObj); // shouldn't be undefined..
    processXML(dr_xml);
}
function processXML()
{
    // yadda yadda
}

this should make it so thisObj should be able to be seen when onLoad is called..

or before the onLoad function of your original code.. add a property to the xml object..

dr_xml.thisObj = thisObj;
dr_xml.onLoad = function() 
{
    trace(this.thisObj); //shouldn't be undefined..
    processXML(this.thisObj);
}

if you dont want to use Delegate..

makes very much sense.. i had a stupid moment, especially since I Delegate all of my other events. Thanks man

[Brucebannor]

I know this isn't going anywhere but I made a very simplistic class to demonstrate the inability of the class to pick up events on flash components. I figured its easier to look at the code than to describe.

Notice I used three different methods of trying to catch the event. Any last insight or idea's?

If not, is this problem fixed on AS 3.0?

If this code is executed in the constructor of your class the problem probably is that the component is not fully initialized when you call the addEventListener.
Try executing the code on onLoad of your class. like this:

//in constructor
onLoad = initCb;
//separate function
public function initCb(){
    cbListener = new Object();
    cbListener.change = Delegate.create(this, comboChange);
    filter_cb.addEventListener("change", cbListener);
}

This only works if your class extends MovieClip.
I always address all my MovieClip and Component instances onLoad, just to be safe.

ok so same class and one more problem.. this is all part of my constructor function. No problem dropp'n this in its own .fla. But its dead to the world as soon as I stick it in the class, any suggestions? thanks

cbListener = new Object();

cbListener.change = Delegate.create(this, comboChange);
filter_cb.addEventListener("change", cbListener);

[xxneon]

is cbListener a property of the class?

[Brucebannor]

I declare it above the constructor as type object: var cbListener:Object;

[xxneon]

and filter_cb is a property pointing to a combo box on the stage then correct?

[Brucebannor]

yes sir, traced all of the components / objects and they all trace correctly.
If I disregard the Delgate like so:

cbListener.change = function()
{
  trace("here");
}
filter_cb.addEventListener("change", cbListener);

its still dead to the world. Could this be a limitation of a class file in AS 2.0? I can't think of what I'm doing wrong, or any other ways to try
