ActionScript 3.0 :: Custom Events Within Package?
Dec 24, 2009
I'm trying to create a custom multi-touch application that consists of a package containing about 6 classes at the moment. I'm trying to find a way to communicate between the various classes when certain custom events happen but am having a hard time making custom events.
I've tried about 5 different tutorials online for creating custom events and none of them have worked. The code is a bit extensive so I won't attach it but the specific situation I'm dealing with goes like this:
There is a drop down menu system that contains file names from an XML file. When the file name is clicked in the menu I want a custom event to be dispatched that I can pick up in another class file that loads the name of that file into a "status bar" textfield element elsewhere in the app, and later a class that will open the file and add it to the stage.

I have a number of folders that contain data for my application. These data will change a lot through the application, creating different functionality for my app. What I want to do is package these folders into a customized file, like zip but not necessarily compressed and then in some way open it through flash and look into the folders. But the user will only have to copy paste the one single package file and not 4 or 5 folders of files every time and maybe leaving something important behind.

I'm creating some custom components and backing code. I've created a Flex library project in Flash Builder which compiles to a SWC. The problem is now that all my MXML files get compiled into classes in the default package, making the whole thing a big mess.Is there a way to set a package declaration for MXML files? After all it just gets translated into AS3 classes. This seems to work in regular Flex projects using a namespace declaration so I'm at a loss how that is supposed to work. The other option is building out all the components in AS3 which I'd like to avoid.

I've been running into a billion problems while creating custom events, so I clearly don't understand some of the basics. All the examples I've found online are unnecessarily complicated, so I've gone ahead and created a super simplified version of how I think it should work. The results are in bold...

So heres the issue I'm haveing, my event listener is not being triggered from the parent, and not retrieving my string for each button being clicked on.
Here is the event listener which listens for the subclass to dispatch an event called MenuEvent.LOAD_PAGE and then passes a string to a variable thats called whatPage thats defined within my custom event.

In Actionscript 3, most events use the capture/target/bubble model, which is pretty popular nowadays:
When an event occurs, it moves through the three phases of the event flow: the capture phase, which flows from the top of the display list hierarchy to the node just before the target node; the target phase, which comprises the target node; and the bubbling phase, which flows from the node subsequent to the target node back up the display list hierarchy.
However, some events, such as the Sprite class's enterFrame event, do not capture OR bubble - you must subscribe directly to the target to detect the event. The documentation refers to these as "broadcast events." I assume this is for performance reasons, since these events will be triggered constantly for each sprite on stage and you don't want to have to deal with all that superfluous event propagation.
I want to dispatch my own broadcast events. I know you can prevent an event from bubbling (Event.bubbles = false), but can you get rid of capture as well?

I'm making a game where you build supports under a bridge to keep it up. I'm trying to add some custom events to my game but I cant seem to get them to dispatch. What I'm trying to do is get the repair shop support to fire an event and tell the bridge and the surrounding supports its been built so they can generate a movie clip and start repairing them selves.If I trace the event it gives me all the correct data after the support is built but the listener on in the repair shop support and on the bridge does not receive it.
Code:
package com.CustomEvents {
import flash.events.Event;

Can anyone help with this, I've been working on it for hours straight and I'm still having major issues.
Sometimes it works great, sliding each new status update down as it should. Most of the time it seems to have completely random positions set. I am completely at a loss. [URL]..
I think it's an event issue, specifically with line 127 trying to loop through the children and dispatch a custom event to all children. I'm not sure how to best do that.

I'm using one of flash's standard FLV skins but want to modify the code and graphics. Not a problem however, I want an animation running around the outside of my player that can also be controlled by the play button of the movie player..... so..animation on outer skin is running or perhaps starts to run when user mouses over that area... video inside is still.... press play button, video starts, animation stops.... press pause, video stops, animation starts...

The fact is that the "dispatchEvent" method must be placed into the code or timeline where the "event" happens, then it can be trigged and the function associated with the event will be invoked. Ok, it is understood. Nevertheless, my question is: what's the point to create an event to trigger the a function call, if I can simply call the function instead directly???
Code:
package{
import flash.events.Event;
public class CustomEvent extends Event{
public static const ONSOMETHING:String = "onSomething";
public function CustomEvent(type:String){
super(type);
[Code] .....
If I can do simply:
Code:
DoIt();
function DoIt(){
trace ("Done!");
}
What I mean is that custom events doesn't look like as REAL events for me, but more like a delegate way to call a function. Differently from Flash native events that are controlled by an internal engine that keep checking if the event happened, in the custom events they must triggered 'manually', and it seems to lose the event main characteristic.

I'm trapping keyboard events on the stage and dispatching custom events through a framework (Mate, though I don't know that this is an important issue), but I'm pretty confused by the scope. The structure is:application (traps keyboard events and dispatches custom event mainPanel (receives dispatched events but mainCalendar (a child element) is null on debugging. Obviously if I try to call a public method on mainCalendar it errors out, even though it's a child of mainPanel. However, mainCalendar is NOT null IF I use FlexGlobals.topLevelApplication.mainPanel.mainCalendar. Outerdocument and parentDocument do not expose mainCalendar either, BTW mainCalendar (a custom component inside mainPanel with public methods. Creation policy is 'all' and it's visible and exists long before I trap any keystrokes at the top level)Could someone take a minute and explain why the mainCalendar is out of scope when mainPanel receives a custom event, even though mainCalendar is a child of mainPanel. Is there a better way to manage the events so I don't have to always address the component via the topLevelApplication?

I have written a custom component for drawing a circle in Flex. But When I try to write a click event or mouseDown event for that component, it doesn't work.[code]...
The "Hello" Alert is displayed only at a particular point and guess is, at the point, (175,150) the x, y co-ordinates of the circle. But shouldn't it be displayed wherever I click on the MyCircle component?? how to enable it in that way?
Also the mouseDown function doesn't work for MyCircle,but if have the event for the VBox, the Alerts are displayed.

We are building an interface for a game. The interface has a tabbed menu at the bottom of the screen, with each tab displaying different aspects of an object (called a node). When you click on one of these parts, it becomes the focus, and we download it's details in XML, including all it's sub-nodes and parent nodes and then update the tab display accordingly, or at least that's what we'd like to happen.
What we have:
MainInterface.mxml
<s:Application...
<fx:Script>
<![CDATA[
public var currentNode:Node = new Node();
[Code] .....
We tried adding an event listener for "selectNode" to the dashBoard:SkinnableContainer you see see above, but it didn't seem to want to take. We suspect this is because dashBoard is from a spark component and the dispatcher for "selectNode" is on of our own custom components, but we weren't sure... in any case that's what the code assist seemed to indicate as we had to write it in by hand. We're not sure how to pick up the Events in FlashBuilder 4's debugger, so we're having trouble working out where it's going wrong.
Basically, when someone clicks on the label of a child or parent node (that is displayed by the itemRenderer), we want a URLRequest sent to our website, with the url specific to the node clicked on. We then want a URLLoader listening for the return which will update public variable 'currentNode' when xmlDownloaded is called by the loader. If you could clarify how the click event should be dispatched, what should be listening for it then sending the URLRequest and where the URLLoader that is listening for the xml data to return should be that would solve our problems.

Basically I am trying to create a string Validator which requests a new language from its controller by dispatching an event upon its creation.
The example below is a straight copy from the Flex3 component explorer - the only diffrence being that I have created the validator as a custom component which dispatches an event upon its creation.
The problem is that my main Application cannot hear the event being dispatched and I don't know why.
Here is the example
MyValidator.as
package components
{
import flash.events.Event;

I'm using ActionScript 3 in Flash Professional and I'd like my class to raise an event, not a custom event but an existing one. I've set up my class so that it extends EventDispatcher. In the documentation [URL] the example declares a custom event by adding a static String variable:
class CustomDispatcher extends EventDispatcher {
public static var ACTION:String = "action";
I assume that enables:
dispatcher.addEventListener(CustomDispatcher.ACTION, actionHandler);
Or at least auto-complete when you've typed 'dispatcher.addEventListener(' into the Flash Professional IDE.
But lots of classes that raise events raise a mixture of existing noncustom events. For example if you have an instance of a flash.netFileReference and type
fileRef.addEventListener(
A long list of potential events to listen for is given including DataEvent.UPLOAD_COMPLETE_DATA, Event.SELECT, HTTPStatusEvent.HTTP_STATUS, SecurityErrorEvent.SECURITY_ERROR, etc.
If I want my class to be registered to raise those existing events, what code do I need? Preferably so that the IDE knows instances of my class may raise the event and suggests them in the addEventListener auto-complete/intellisense list.

I'm working on a project in flex and I have a few questions pertaining to performance. First off I know that I cannot write multi threaded programs but I understand the internals of the flash player are multithreaded1. when i call ActionScript Code:loaderObj.load(new URLRequest("ljdsfglsdhflsd")); will flash player make a new thread for that?2. I am also interested in making a custom Event class will the listener (which i assume is a loop that runs once per frame or more) run in a different thread. I want to minimize CPU usage as much as possible in areas I can.

I have made a site in AS3.0 code and it's working fairly well but theres alot of things i'm trying to update to make the code a little more reusable. For startersI have a function that creates a little pop-up text when I roll over a button. The text is a class that I created in the Flash IDE instead of dynamically drawing it with actionscript.Here is the code for the pop up text instance called "enter_text" as it rolls over the movie clip "preloader_mc"
Code:
//add listeners to the preloader_mc movie clip on stage
preloader_mc.buttonMode=true;

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 am working on actionscript to generate a SWF dynamically using JSON data coming from an HTTP request. I receive the data on creationComplete and try to generate a tree like structure. I don't create the whole tree at the same time. I create 2 levels, level 1 and level 2. My goal is to attach custom events on the panels which represent tree nodes. When users click the panels, it dispatches custom events and try to generate the next level.
So, it goes like this :
On creation complete -> get JSON-> create top tow levels -> click on level 2-> create the level 2 and level 3 -> click on level 3-> create level 3 and 4. and so on and so on. I am attaching my code with this email. How to do this if you need to paint a tree having
total level number = "n" where n = 0 to 100
Should I carry the data around in CustomPageClickEvent class.

import flash.events.MouseEvent;

I'm taking my first stab at writing a custom flex 4 component by extending the UIComponent class. Unfortunately, I cannot get the component to respond to any sort of mouse events.I've tried setting mouseEnabled to true is the component, as well as setting mouseChildren to true in the parent (the stage object). It seems whatever I do, my click events can be detected from the stage, but not with the component.Here is my component class:
package components {
import mx.core.UIComponent;
public class DrawCanvas extends UIComponent {

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).
