Re: [Flashcoders] Delegating Events and AS2
The problem is with this code- the onRelease function is a method of
the btn movieclip... so it doesn't have access to the dispatchEvent
function.
btn.onRelease = function() {
trace('dispatching event');
dispatchEvent({type:'click', target:this, message:btn+' was
clicked'});
};
You could just do something like this instead if you want a quick
local function:
var btnRelease = function () { dispatchEvent({type:'click',
target:this, message:btn+' was clicked'}); }
btn.onRelease = Delegate.create(this, btnRelease);
Delegate saves the day again...

It is firing off the event perfectly but my listener is not getting

Re: [Flashcoders] Delegating Events and AS2
I'm not totaly sure, but you don't have to specify target - that's something
that Delegate already adds to the event object it passes along

Re: [Flashcoders] Delegating Events and AS2
I think Delegate gives you what you're talking about Vic - control over your
scope issues. Delegate enables you to manage scope with in your class. So,
if you have an XML object and you want to maintain the response/return in
your class, you do just as Dan has described.
make sense?

Re: [Flashcoders] Delegating Events and AS2
Vic, if you've ever used the XML or NetStream classes... it mimics
those types of event updates. For example...
var xmlData = new XML();
xmlData.onLoad = function () {
// gets invoked by the XML instance
}
So if you delegate the onLoad method, you get something like this:
xmlData.onLoad = Delegate.create(this, xmlDataLoad);
... which is essentially what I am trying to do with my own classes.
Another reason I like delegating events this way, is that the
compiler will catch typos in the names of the event functions, so I
am not searching around trying to figure out why a certain event is
not firing.

I personally use an extremely simplified way of dealing with events.
I've used EventDispatcher before, but it feels like overkill most of
the time. I realize my method has no ability to multicast events,
but it's quick, easy to read and gets the job done.
Here's an example:
___
// WidgetManager.as
import mx.utils.Delegate;
class WidgetManager {
private var _widget1:Widget;

Re: [Flashcoders] Delegating Events and AS2
Hey Dan, I like the way you do it, its pretty simple. But here is, what
probably will be an incredibly stupid question:
How do I capture the event? Thanks, V
I personally use an extremely simplified way of dealing with events.
I've used EventDispatcher before, but it feels like overkill most of
the time. I realize my method has no ability to multicast events,
but it's quick, easy to read and gets the job done.
Here's an example:
___
// WidgetManager.as
import mx.utils.Delegate;
class WidgetManager {
private var _widget1:Widget;
private var _widget2:Widget;
public function WidgetManager (timeline:MovieClip) {
_widget1 = new Widget(1, timeline.widget1_mc);
_widget1.clickEvent = Delegate.create(this, widgetClick); // add event
_widget2 = new Widget(2, timeline.widget2_mc);
_widget2.clickEvent = Delegate.create(this, widgetClick); // add event
}
private function widgetClick (eventObj:Object):Void {
trace("widget " + eventObj.id + " was clicked");
eventObj.target.clickEvent = null; // remove event
}
}
___
// Widget.as
import mx.utils.Delegate;
class Widget {
public var clickEvent:Function; // event method
private var _id:Number;
private var _buttonMC:MovieClip;
public function Widget (id:Number, mc:MovieClip) {
_id = id;
_buttonMC = mc;
_buttonMC.onPress = Delegate.create(this, buttonPress);
}
public function buttonPress ():Void {
clickEvent({target:this, id: _id});
}
}

RE: [Flashcoders] Delegating Events and AS2
Why not just use mx.events.EventDispatcher? All you have to do is set up
"dummy function" named addEventListener, dispatchEvent,
removeEventListener, and then use EventDispatcher.initialize(this) in
the constructor.
Or, if using AS3.0, I think you can wrap a flash.events.EventDispatcher
object (Decorator Design Pattern):
import flash.events.Event;
import flash.events.EventDispatcher;
import flash.events.IEventDispatcher;
class MyClass extends MovieClip implements IEventDispatcher {
//...
public function MyClass() {
//...
_dispatcher = new EventDispatcher(this);
}
public function addEventListener(type:String,
listener:Function):Void {
_dispatcher.addEventListener(type, listener);
}
public function dispatchEvent(event:Event):Void {
_dispatcher.dispatchEvent(type, listener);
}
public function hasEventListener(type:String):Boolean {
return _dispatcher.hasEventListener(type);
}
public function removeEventListener(type:String,
listener:Function):Void {
_dispatcher.removeEventListener (type, listener);
}
public function willTrigger(type:String):Boolean {
return _dispatcher.willTrigger(type);
}
private function _dispatcher:EventDispatcher;
}
(Note: I haven't actually tried AS3.0, so someone let me know if I
messed anything up.)

Re: [Flashcoders] Delegating Events and AS2
I have been using this class for all my event needs. Simply import the
class, then to use:
EventManager.getInstance().addListener("eventDoThis", this); //adds the
listener to the class ('this' is the scope)
EventManager.getInstance().removeListener("eventDoThis", this); //removes
the listener
EventManager.getInstance().dispatch({type:" eventDoThis", param:true,
param2:false, param3:"etc"}); //sends the event with params
private function eventDoThis(eventObj:Object):Void
{
trace("eventDoThis called");
var p1:Boolean = eventObj.param;
var p2:Boolean = eventObj.param2;
var p3:String = eventObj.param3;
}
For me, this setup is nice and clean to use. Just be sure to keep it as a
Singleton to prevent additional EventManagers from overriding this one.
***CODE*
//EventManager.as
import com.core.events.*;
class com.core.events.EventManager {
private var eventListeners:Object = new Object();
private static var _instance:EventManager;
private function EventManager(Void){}
public static function getInstance(Void):EventManager
{
if(_instance === undefined){
_instance = new EventManager();
}
return _instance;
}
//dispatch broadcasts the event to all who are setup as listeners
public function dispatch(eventObject) {
var tmpA:Array = eventListeners[eventObject.type];
// Loop through this way to avoid problems with adding/removing
listeners during the dispatch
for (var i in tmpA) {
tmpA[i][eventObject.type](eventObject);
}
}
//add a listener to the queue, this will get called once a dispatch
event happens that matches
public function addListener(event:String, listener:Object) {
if (eventListeners[event] == undefined) {
eventListeners[event] = new Array();
}
removeListener(event, listener);
// a listener should only listen to an event once
eventListeners[event].push(listener);
}
//remove the listener from the queue, this prevents additional
rebroadcasting.
public function removeListener(event:String, listener:Object) {
var tmpA:Array = eventListeners[event];
var len:Number = tmpA.length;
