Here is your code modified to use the EventDispatcher:
import mx.events.EventDispatcher; // import the event dispatcher
class com.boa.projects.iqrcgenerator.components.AdminData{
public var addEventListener:Function; // Set the functions
public var removeEventListener:Function; // Set the functions
private var dispatchEvent:Function; // Set the functions
private var userData:Object;
// I'm sure you have a different constructor, but you need
// to add that line to it if you want to use the eventdispatcher
public function AdminData(){
mx.events.EventDispatcher.initialize(this); // add this
to constructor
}
public function wsUserDataByLOB(lobDbId:Number):Void{
var getUserListResult:Object = new Object();
getUserListResult =
generatorWebService.GetUserList(lobDbId);
var r = this; // To get this in onResult
getUserListResult.onResult = function(oUser){
r.dispatchEvent({type:"eventOnResult",
user:oUser}); // Dispatch the event
}
}
// I may just take this function out all together since the
event can
// autommatically send them the data.
public function getUserData():Object{
return userData;
}
}
Then in your other class you can do something like:
//myAdminData is an instance of the class above
var r = this;
r.eventOnResult= function(evtObj:Object){
trace("user: " + evtObj.user); // Should return the oUser
object
}
// addEventListener takes the event name, and who you want to listen
myAdminData.addEventListener("eventOnResult", r);
Does that help? I obviously can't test the code, but I think everything
is right... I have trouble with scope, which is why I use a lot of 'r'
values instead of 'this'... Just easier for me... Probably not a good
coding standard :)

Subject: [Flashcoders] Events for custom classes?
OK, I'm pretty good at Actionscript 2.0, but something I never really
understood and now need to.
Core question: How do I make an event in a custom class, and how do I
make a listener in another class listen for the event?
EventBroadcaster in the help docs seems to only show how to use it with
Adobe classes and components. Docs on listener are the same. I know how
to set up listeners for other events, like keypresses and mouse
rollovers. Easy enough. But my problem is this (see comments in code
below):
class com.boa.projects.iqrcgenerator.components.AdminData{
private var userData:Object;
public function wsUserDataByLOB(lobDbId:Number):Void{
var getUserListResult:Object = new Object();
getUserListResult =
generatorWebService.GetUserList(lobDbId);
getUserListResult.onResult = function(oUser){
//this works fine,
//I can capture this event result here,
//but how do I notify another class?
//also what about scope here?
//how to set userData as oUser result?
//can I fire an event in my AdminData
//class from here?
}
}
public function getUserData():Object{
//can't let user get this data
//until Webserive event is done.
return userData;
}
}
Thanks,
