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.
`i'have a problem with listening events dispatching from their child classes. for example i have contentManager object which is controlling content at the top level of stage. it has a imageGallery object and in the imageGallery objectthere ise a collectionLoader object which is loading images.
now i want to add one preloader to contentManager which always listen for ProgressEvent. when the progressEvent dispatched i want to preloader going to active. becouse there is another objects that are loading images or other kind of files. i think it is a good apporach to solve preloader issue. so my problem is, when collectionLoader object loading images with using queLoader. my QueueProgress event dispatches ProgressEvent evey time, but my preloader object stand at the 2 classes up level, doesn't percive this event.
Does anyone know if it's possible to listen for all events fired from an object without having to specifically listen for each one?
View 5 RepliesI 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?
View 5 RepliesI'm using a electronic device to dispatch events within AS3.
short explanation: -->
Think of these events as a KeyboardEvent.My point is to dispatch an Event (like a Key that is being pressed) so I can listen to this event on EVERY Class I need to.I'm not sure how to instantiate or listen to these events correctly =/
I mean: I want to be able to listen to the key that is been pressed as if that was a global event every Class can receive...
long explanation: --> I'm doing something like this:
1) created a (main) Class that extends a Sprite.
2) created a class (KeyboardInput) that extends the main class.
3) created a class (KeyMap) that extends EventDispatcher.
4) created a class (HomeScreen) that extends a Sprite.
My FLA file is associated to the KeyboardInput Class.This Class creates a listener for the KEY_DOWN KeyboardEvent and instantiate the KeyMap Class that dispatches a CustomEvent:
stage.addEventListener(KeyboardEvent.KEY_DOWN,function(evt:KeyboardEve nt):void { keymap = new KeyMap(); keymap.setKey(String.fromCharCode(e.charCode)) });[code].....
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'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.
View 1 RepliesThere is my scenario:
I have a BorderContainer that is contained by a Scroller.
Question :
How can i make my BorderContainer to listen for Scroler events?
e.g. When i scroll down or up, or right or left, i want to change my BorderContainer's cordinates(x, y).
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(...)

View 1 RepliesIs this the most efficient way to listen to mouse events on the background of a group?
<s:Group width="200" height="100" rollOver="group1_rollOverHandler(event)" rollOut="group1_rollOutHandler(event)">
<s:Rect width="100%" height="100%">
<s:fill>
<s:SolidColor alpha="0"/>
</s:fill>
</s:Rect>
</s:Group>
seems pretty minimal, but alpha = 0 is not the most efficient thing out there.
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 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).
Are there suggestions for code that will essentially listen for (or test) for mouse clicks on 3 separate buttons. Once all the correct 3 buttons have been released, I want a to trigger a final event(load a 4th movie clip). I can't stop thinking in terms of IF (all event 1 + event 2 + event 3) THEN load movie. But I know that isn't AS3 way to do it, any better understand way to do it with event listeners (but not too complicated!)

I am writing a flex application and I have two Spark TextAreas. I want to create an EventListener so that when the user clicks on a text area, the text inside the TextArea is cleared:

if (this._showsCaption) {

Currently I can implement this with a Spark TextInput, but when I click on the TextArea, the focusIn event never fires and the onFocusIn() handler is never called.

How do I listen to an event dispatched from non-display-list concrete objects which are created by a singleton factory class?
An example would be where I want to create tweens for objects using a TweenFactoryClass. In my Main.as class I have this:
ActionScript Code:
TweenFactoryClass.instance.tweenMe( myClip, 200, 200 );
then, in my TweenFactoryClass.as, I have:
ActionScript Code:
public function tweenMe( clip:DisplayObject, xLocation, yLocation ):MyTween
{
var tween:MyTween = new MyTween();
[Code].....
I don't know where I should add the listener to be able to hear that event that was dispatched from the MyTween class.
Can a parent .swf listen for an event in a child .swf?
View 3 RepliesImagine 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 have a dialogBox with 2 buttons - ok_btn and cancel_btn. The code is in a Class - testDialog.
There are 2 issues:When any of the 2 buttons clicked, they dismiss the dialogBox without sending any alert to the parent (main time-line).How to trap the clicked buttonId in the parent.I have just an idea of the solution as dispatching an event in the child and listen for that event in the parent. But, unfortunately, I don't know how to go about it.
To make my point clear, here is the code:
Code:
package
{
import flash.display.*;
import flash.events.*;

Both class (Dispatcher & Listener) are Child class of a MXML application. Also listen to the event in the parent MXML application doens't work. Listen to the event in the dispatching class itself somehow works.
I have to feeling that the EventDispatcher class is not the right one to dispatch events to a mxml application or respectivly AS classes, which extend/inherent from a MXML component class.

I'm trying to handle movement of my Hero Class by adding event listeners in my constructor. I'm trying to move my Hero object.Inside my hero constructor, I have:
