I have got a custom event set up (see below), but when I listen for the event in my main class, and it gets dispatched from the child class, it never gets captured.

I have two swf file, A.swf and B.swf, each with its Document Class: B.swf is loaded in a MovieClip of A.swf. When loaded, B.swf creates an instance of CSDragger (it is a library object with its class extending MovieClip) and sets an ID property of this instance to a certain value. When this dragger is dropped by the user upon a MovieClip it sends a custom event containing the value of ID too. The custom event regularly reaches B.swf but never reaches A.swf. Aside from refactoring the CSDragger class (eg moving its handleDrop method in the B.swf document class), is there any way for the event to reach A.swf? I know I can intercept it and dispatch another event, but I was looking for a different solution (if any).[code]
View 1 RepliesI am building a compartmentalized Flex application which uses <SWFLoader > to load additional Flex applications inside it. I am currently planning on using the LocalConnection class to have these two applications talk to each other, but I'm wondering if there's any kind of event driven way to have actions in the internal application propagate to the parent application, and/or any way for the parent application to trigger events in the internal application?
View 1 RepliesI have a simple 2 class game Im working on. It has a document class (BubbleBuster.AS) and a Bubble class (Bubble.AS). In the doc class I made a container sprite called bubbleContainer. I add bubbles (instances of Bubble.AS) to the bubbleContainer. When the game is over I fire a custom event in the bubbleContainer from the doc class like so:Code:bubbleContainer.dispatchEvent(new Event("gameOver"));Now I want to listen for this event in the Bubble children so I can kill tweens and remove things. So in the Bubble.AS I have:Code:parent.addEventListener("gameOver", gameOver);this compiles fine. But as soon the 1st Bubble is added to bubbleContainer I get this error (and no bubble appears):TypeError: Error #1009: Cannot access a property or method of a null object reference.

I have a sprite A which has a child, sprite B.Sprite B has a variable, instance of class C which only extends EventDispatcherIn class C, I dispatch a custom Event. The eventlistener in sprite B reacts on the event.The same eventlistener in class A doesn't respond.If I dispatch the same custom event in the eventhandler in class / sprite B, this event is seen in class / sprite A.Is there a difference in events going through the displaylist and those who are from an EventDispatcher?

I'm building an all flash site, where one .swf acts as the parent, and other external child .swf's are loaded in using .xml. The "Child.swf's" are a mixture of timeline animations, and coded swf's, and the problem I'm having is that they immediately start playing as soon as they are loaded. I've not been able to find any straightforward "child.start() or child.stop()" solutions, so I assume it's more involved than that.
I thought it might be a good idea if I could dispatch events from the parent swf that will set them going. I'm using the sharedEvents method to communicate in the reverse direction (child to parent), but I don't believe it can be used from parent to child (Please correct me if I'm wrong!) I know I could go to each child and put "stop();" in the first frame, but how do I start it again? I would also prefer it if not all the child .swf's started immediately, but to wait until others have completed their routines. Again the way I see it is to dispatch an event from the parent .swf as soon as I'm ready to set them going.
I cannot bubble the event because I want to send to another class that is not even a movieclip but a simple class. So I transform previous source code here Is it impossible with Flash to get the Instance Creator ? for

I have two swfs for a project, I had both of them to dispatch events to each other. Parent loads child and is listening for the compete load event. Once that event is dispatched to the child - the child dispatches a start event back to the parent. I got this working by copying the ModelEvent(my custom event) in each of the flash builder actionscript projects in the exact file structure ( i think i was cheating it there, since )
It broke when I put the swf on separate domains, so I'm thinking I'm missing something to share the custom event class between two swfs.

In short: I need an event listener in a custom component so all its instances (without editing them) react at the same time, fired by a dispatched event in its parent container. In detail: I have a custom component with Tab navigator. (The tabs are intended to show different preferences for different Languages.) I have a button bar with buttons for all the languages. There are a lot of instances of the custom component.
I want to click in a button of the languages bar and get ALL the instances switched to the same tab (the custom component contains the logic to change the tab). I can do it by adding the event listener for EACH INSTANCE of the custom component, so it calls an internal function that changes the tab. But it seems to be very coupled, isn't it? I wonder if it can be done in the master CLASS of the component, so it listen for events in its parent container, whichever it is. In my mind this code shoud work, but it doesn't (obviously ill'use a custom event to pass the new language value): this.parent.addEventListener("lang_change", this.change_tab); This way I can just drop an instance of the component, and see it working for itself.
I want to listen for a custom event dispatched from the document class in a custom subclass. For example, let's say in the document class I have:
ActionScript Code:[code]....
So that the subclass will trace 'Event from document class received' when the 'customEvent' event from the document class is listened by the eventlistener. However, the output is only 'customEvent dispatched', meaning it wasn't heard in the subclass.
I have movieclip which contains child movieclip. when child movie clip finish to play i want to run a function in a parent movieclip. so I made a custom event dispatcher in the first frame of the child movieclip:

This is NOT duplicate of my earlier post (its is slightly different)But this is similar issue with similar error but its not the same error The error I am getting now is below while dispatching the custom event from my custom component
TypeError: Error #1034: Type Coercion failed: cannot convert events::MapEvent@a74ab51 to flash.events.MouseEvent.
dispatchEvent(new MapEvent(MapEvent.CLICKED_ON_MAP));
Note: The error in my earlier post is giving below error message
Type Coercion failed: cannot convert flash.events::Event@81ecb79 to com.events.ShopEvent
The difference here are two things, the earlier error is while converting flash event to custom event and now this one is while converting custom event to flash event and secondly, I have no clue why it is trying to convert to the mouseevent where I am just dispatching my custom event with proper listeners.
This is my custome event

{
import flash.events.Event;
import ui.map.MapElement;

Is there a point of creating custom event class if i dont need to pass custom property with that event?
View 3 RepliesI hava a custom component and it contains a child icon. If I add a mouse-click event listener to both component(click-listener1) and icon(click-listener2), the event dispatched sequence is click-listener2, then click-listener1. I can understand it. But if I add a custom event to component (listener1), and mouse-click event to icon(listener2), when icon is clicked, the component will dispatch the custom event. In my test, the event dispatched sequence is listener1, then listener2. It doesn't match with event-bubbles rule.
In my opinion The custom event is dispatched in listener2, which triggers listener1. Why event flow sequence is not listener2, listener1?
In component.
icon.addEventListener(MouseEvent.CLICK, iconClickHandler);
private function iconClickHandler(event:MouseEvent):void

I have these buttons in a movie clip and I would like to have only one event listener for the parent, using event.target to point to the children. I have also tried event.currentTarget, and it didn't work.here is the code that works:
test01.abtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);
test01.bbtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);
test01.cbtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);[code]....
It is only targeting the movie clip, not the buttons inside the movie clip.
I have the following situation:I have an event handler, that displays small messages in my application's statusbar.These messages get passes through by dispatching events from custom components.A simple message could be like "HTTP Error" or so.Now, the main event listener, in the main application file, listens to the event dispatched by any custom component,but seems to refuse listening to events dispatched by custom AS classes.Here is my code for the custom event:
package main.events
{
import flash.events.Event;[code]..
So to sum it all up:
- The event listener listens to the custom event dispatched by any custom component.
- The event listener does not listen to the custom event duspatched by an AS class.
Those who wonder, the event really gets dispatched, that's why I added a trace call.
i am a bit embarassed to ask this, but i do this so much i have to ask. Occasionally, i need to pass/handle custom events on the fly. Rather than creating a whole custom event class, i will just do something like
Code:
myObject.dispatchEvent(new Event('thisCustomEvent'));
//and then handle it later

Does anyone know how to propagate tweener mouse events only to the children of a movieclip? I have an mc with small thumbnail images inside that are also mcs.

View 1 RepliesHow to trigger a custom jQuery event from Flash, passing some data through event object?
View 2 RepliesI am trying to understand event propagation in Flex framework and have a following doubt on it:
Scenario: I have a built-in component DropDownList on change of which I want to create a custom event refreshPreview and want to propagate it to a custom component PictureComponent.
In the custom component's mxml, I have added the Metadata directive as follows to register a refreshPreview event with the compiler
<fx:Metadata>
[Event(name="refreshPreview", type="flash.events.Event")]
</fx:Metadata>
Layout Details: In my main mxml application I have laid out DropDownList and the custom component such that both are siblings (i.e. have a common indirect parent)
e.g.
<s:Group id="contentGroup">
<s:Group id="formGroup">
<s:Form x="11"
[Code]....
I am seeing that the refreshPreview event is not getting propagated to the custom component.
I doubt this is because the built-in component is a sibling of the target (where the event got generated) and not a parent. how to make refreshPreview event propagate to custom component?

I'm using a Static EventDispatcher for all event handling in my application, and one of the issues with it is that the Static EventDispatcher becomes the target and currentTarget of the custom Event. Usually, I just pass the event to the custom event which it will carry as its own property. I usually call it "scope". So, instead of using "evt.target" or "evt.currentTarget" in the event handler, I use "evt.scope.target" or "evt.scope.currentTarget" instead. This works fine.
The issue is that I want to simplify this with custom events by overriding the target and currentTarget methods so that they return scope.target/scope.currentTarget. At run time, I get an error saying that I cannot convert Event to whatever I named the custom event. So, I tried not extending Event, and that produced an error stating that the class function is expecting exactly 0 parameters. I just want to make it so that people using Static EventDispatcher handling events as they normally would.
So, the question is there a way to override target and currentTarget while extending the Event class, or is there a way to create a custom event without extending Event?
I am writing a program in OOP and I have a custom subclass which I make a new instance of in the document class. When I do make a new instance of this custom class, I want this (the custom subclass is a movieclip) object to be positioned at the center of the stage. However, when I try
