Actionscript 3 :: Create A Separate Class For Each MC Inside Of The Container To Listen For And To Dispatch Events?
May 25, 2011
Imagine you have a MC used as a container for several other MC's used as buttons.Now, should I use the class of the container to listen for and to dispatch events. OrShould I create a seperate class for each MC inside of the container to listen for and to dispatch events.
In summary: One class for all, or several smaller classes dedicated to their respective MC.How far should one go with abstraction?.

I'm using an accordion container that has it's creation policy set to auto. One of the accordion's children is a spark border container that has a data grid within it. Currently, I'm using the data grid's creationComplete property to call a function; similarly, I'm using the dragComplete property to call another function.
How can I add listeners for events (creationComplete & dragComplete) via actionscript? The obvious problem is that the accordion does not create all its children on creation (nor do I want it to), so I can't simply use something like: datagrid.addEventListener(...)

I'm trying to listen for events sent from my main movie swf from inside a preloader shell swf.Inside Preloader.swf, I load my Main.swf in the traditional way, with a loader object and I listen for progress events on that. These progress events make my preloader bar scaleX increase, like normal. But, I have an XML file and an image that load inside of my Main.swf as soon as it is loaded. I would like for these unloaded bytes to be shown in my Preloader.swf before the Main.swf gets added to the stage.right now, I am sending the totalBytes from the XML file and the image to my Main.swf document class, which, in turn, dispatches a custom "PreloaderEvent" that holds the total number of bytes.
In Preloader.swf, I add an event listener to the loader ( which holds main.swf ), listening for that PreloaderEvent.Can events be heard in this manner and is this the best way to be preloading this type of file ( one where main.swf loads in the first frame, then starts loading of external images after the swf is running ).I'm just not sure how to get all of those extraneous bytes into one location for my preloader to see at the same time.

I'm trying to detect when pop ups are visible (including tool tips if possible). The reason is that I need to hide or freeze (capture a snapshot) the Stage* components (StageWebView, StageVideo, StageText etc) when pop ups appear.

I have an <mx:Application> which contains a <mx:Module>. This module has several child modules. It also has some an instance of a class I have created. I am trying to have a method of this class dispatch an event that can be "heard" by the module and handled. This isn't happening.To be more clear, I am using 'dispatchEvent' to from inside a class method.There is an instance of this class in: mx.core.Application.myapplication.mymodule.myclassIt is the 'myclass.somefunction' that dispatches the event. I have a listener registered in 'mymodule'. Nothing happens when the function/method runs, however.

I came to some misunderstanding how to use events. LOL. I thought I understand it but as I see I dont.
I've got a Engine document class where Hero is added, and Cannon object too. In body of Hero I need to dispatch event when Hero reaches some point or particularly a pitfall, so I've got static const string to handle it:
[Code]...
but this way I would end up with dozens of handlers in the Engine body class, and I am trying to minimize this class as it is big enough without those handlers. I am stunned and suprised, and I am noob again. Maybe someone will clear out how to get custom events working/... and why only instance of object that dispatches an Event can hear it (my case).

I'm new to Flash AS3. I started making a game and I am a bit confused. Let's assume that I want to create a game that has multiple levels/modes, how can I do this in an object orientated way?
When i create games in other languages e.g. XNA C#, i create a separate class then create an object of that class within the main class and run the game based on a simple statement.

I know there's been quite a few posts about events, but I've run into a problem that I haven't really encountered before, and I've kind of confused myself with all the talk of "bubbles" and "capture" and various complexities of creating custom events, etc...Anyway, I'm trying to figure out how to dispatch a global broadcast style of event.1) If I have a custom class that resides in the Display List (the DispatcherClass), how do I set up this class to broadcast a "global" event?Actionscript Code:1b) If I have another custom class that also resides in the Display List (but in a completely unrelated heirarchy), how do I get this ListenerClass to "hear" the event WITHOUT explicitly referencing the instance of the DispatcherClass like so:
Actionscript Code:DispatcherClassInstance.addEventListener("DispatcherClassEvent", handler, false, 0, true);Is this even possible?2) What if the DispatcherClass DOES NOT reside in the DisplayList?Is it possible to dispatch a "global" style event since there is nothing to "bubble" up through?2b) How would I get a ListenerClass, maybe on the DisplayList, maybe not, to "hear" this event?

I have a popup window. In that popup window, when a user clicks a button and moves out of the popup window, the event should stop. How can I achieve this in flex?
Simply to say, if a mouse moves from the title window or any other container to the outside of the window or component, I want to listen to that event.
I tried with focus out but that fires only when user clicks or changes the component. I also tried with the mouse out event, it also didn't work for me.
how to listen for the event when a user moves a mouse from inside a component to the outside of the component?

I have two separate advancedDataGrid instances (let's call them A and B). What I'd like to do: when clicking on grid A. I'd like:
for grid A to handle the click normally (i.e. default advancedDataGrid behavior)
for grid B to receive a click event a certain location and handle such event using advancedDataGrid default behavior (i.e. without having to write a handler for such click).
I've managed to dispatchEvent a MouseEvent.CLICK to grid B and to handle such event by creating an event listener, but really I'd like for grid B to handle the event on its own (i.e. without having to re-rewrite a handler), and that doesn't seem to be the case. Is MouseEvent.CLICK even the right event?

I have an SWF that has been provided to me that I need to load. Inside that SWF are two buttons ("cancelButton" and "proceedButton"). Is there any way that I can add event listeners to these buttons from within my action script after I have loaded the SWF or do I need to get the SWF creator to create event listeners on the buttons that can bubble to me?

A swf (my game framework) loads another swf (a game). The game is loaded into a child domain which seems to be the default domain for loaded swfs.
The framework listens for custom events bubbling up from the game. However, the framework only receives events dispatched directly from the games document class but not from any of the games children.
Bubbling is set to true on everything, but it's not working? Is it only possible to dispatch events from the document class of the loaded swf.
swf(Framework -> listen) -> swf(game document root -> child) = no go!

I just started to use classes in AS3. I stuck to event handling between classes. That's what I want to do, but don't know how to do it:
1) set up event listener in a child class
2) when this event in the child class is triggered, the child class, the parent class and several other child classes respond to the event.

in Adobe tutorials, they suggest to create a class to handle the events (see below the copy/pasted code, and link to page).I was wondering if I have to handle all events with the function handleAllEvents, using if statements to check if the target is the one I want, and the event is the one I want.i.e. if (event.type=="click") && (event.currentTarget == "myId")Should I have a list of ifs (for each target and each event type ?)[code]

This is what i'm trying to do :
I have 1 class that extends movieclip, let's call it Class0. I have 1 class that extends movieclip, let's call it Class1.
I create an instance of Class0 on stage like : var myClip0:Class0 = new Class0(this, "Class1");
The class Class0 when initializing, will create a new movieclip (myClip1) and add it as child, as an instance of Class1, like myClip0.myClip1. But it's when i create that clip, i want to tell it, it's an instance of Class1, like :
private var myClip1:Class1 = new Class1(this);
Where Class1 could be any class.
How do i pass Class1 to Class0 so it can create it dynamically?? Do i have to use the apply function??
inside Class0, i have a function that does :
Code:
if(subClass){
initSubclass(subClass);
}

I'm still trying to get my head around the best way to structure event flows. Someone made a lot of sense by telling me that contained objects should be decoupled from their parent containers so they're reusable between containers. Instead of calling their parent's function, they dispatch an event. Sensible! I recently myself in the awkward-feeling situation of dispatching an event on a contained object, from its parent. It seems more intuitive for an object to be the one dispatching its own events. Maybe I'm bordering on breaking the Law of Demeter? Example of what I'm doing: child.dispatchEvent(new ChildEvent(ChildEvent.IM_BEING_A_CHILD)); Am I correct in feeling strange here, or is it a normal thing for one object to dispatch another object's events?

So, events bubble up the display list. That's great if that's what you want. But what if you have objects on the stage that are not related that need to listen for events from each other? A simplified example:
var objA = new ObjA;
addChild(objA);
var objB = new ObjB;
[Code]....
Object B can listen for events dispatched by object C. But I also need object A to listen for events dispatched by object C. Also, these objects are created in different classes so I can't hard code references to each other.
