Re: [Flashcoders] advantages of EventDispatcher over AsBroadcaster
Just setup your eventListeners to pass the decoupled data to your ready
functions.
dispatchEvent({type:eventClipShowStatus, target: this, current:
currentMCNumber, total: totalMCNumber});
private function eventClipShowStatus(eventObj:Object):Void{
clipShowStatus(eventObj.current, eventObj.total);
}
Make sense?
This preserves your function logic and adds a decoupler for all your data
being passed around. You can also error check inside the event function to
be sure proper data was passed before calling clipShowStatus.
Hope this helps,
Steve

After your post I spent most of this morning researching and debating
converting a lot of my code to use the EventDispatcher instead of
broadcastMessage. I like a lot of what it has to offer, but have a
question...
I have a function in one class that displays how many more movieclips the
user will be viewing and it takes in two variables: currentMCNumber and
totalMCNumber. Using broadcastMessage, I can pass those variables in
directly. Can I do that with the eventDispatcher as well?
For example, doing:
this.broadcastMessage(clipShowStatus, currentMCNumber, totalMCNumber);
Runs the clipShowStatus function as if I had actually done:
clipShowStatus(currentMCNumber, totalMCNumber);
But if I use the eventDispatcher I would need to do something like:
dispatchEvent({type:clipShowStatus, target: this, current:
currentMCNumber, total: totalMCNumber});
And make changes to my clipShowStatus method to take in an event object...
Is there a way to use the EvenDispatcher with out needing to change all my
functions to take in eventObjects and instead place the needed variables
directly into the function?
Thanks!

AsBroadcaster
The two are pretty much the same, except for one big thing:
EventDispatcher allows you to distinguish between types of events.
AsBroadcaster just says, Hey, there's been an update, while
EventDispatcher gives detailed information (in an Event object) about
exactly what that event was and only notifies the listeners which are
listening to that type of event.
Another advantage to using EventDispatcher is that EventDispatcher is
heavily integrated into ActionScript 3.0, to the point that at least
half the classes you'll encounter are dispatchers. Every single
display object (movie clips, buttons, components, etc.) is a
dispatcher, some with dozens of types of events (mouseMove, load,
enterFrame, etc.). AsBroadcaster, on the other hand, is deprecated.

I have used both extensively and find that AsBroadcaster allows me to
do the same thing in fewer lines of code, yet there seems to be a
general preference in the flash community to use EventDispatcher.
Is there any particular reason to use one or the other?

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;
for (var i:Number = 0; ilen; i++) {
if (tmpA[i] == listener) {
tmpA.splice(i, 1);
return;
}
}
}
}
***END CODE*
I hope this helps you out, let me know if you have any problems with it or
have any additional questions.
Steve

Subject: [Flashcoders] Delegating Events and AS2
Hi All!,
wondering if someone can point me in the right direction. I am trying
to find a ASBoradcast / Event Dispatcher light model for my app.
Basically i have a number of MCs that will have to either react to
events being broadcast or broadcast their own.
I have Essential AS2 by Colin Moock. Trying to find something i can
import and maybe pass scope to it, vs have my main class extend it.
I've googled, searched the archived and exausted my more talented
flash developer friends.
Thanks,
Sean

RE: [Flashcoders] anyone using mCom?
The components themselves are great. They are lightweight, generally easy to skin, and the API is very compatible with the v2 components that MM ships. With that said; the company that acquired the set, Metaliq, does not appear to be interested in documenting or supporting them. I have sent numerous emails/tickets trying to get better documentation, but have not received a reply yet on that issue. At one point, Grant Skinner said his people would try to get them to update the documentation, but this has not happened yet. Direct from their website you can see the last update was: September 1st, 2005 Version 1.0.124.

[Flashcoders] v2 Button Label width?
I have searched google, the list, MM/Adobe, help files and my new book, Advanced Components. I cannot seem to figure out how to determine the width of the Label embedded into the v2 Button component. I will be loading many different languages via Unicode into the label and will not know the exact size to set until I have fed the text into it. In looping through its properties I have determined the Label is stored in labelPath. The other option I am trying to avoid is rendering an identical string into an invisible label component to determine its size. The only option I see right now, is using a non-monospaced font. Any help would be appreciated.

RE: [Flashcoders] v2 Button Label width?
Setting sizes is not the issue. I need access to the size of the label after running autoSize = left and adding text to the label. I am putting in unknown text into each button and will need to resize them according to the text (Unicode) length. This is mandatory since these buttons are part of a application UI that sizes according to the nationality's current language. Using _width always returns the same result, no matter what size it is. textWidth returns undefined.
