ActionScript 3.0 :: Use Of Events Bubbling And Catching?
Apr 24, 2010
I've been developing in flash for about 5 years now and consider myself a solid intermediate level developer, but I have a gap in my knowledge of events. I don't understand when bubbling events or catching events would be beneficial. I'm guessing there is a very obvious use for them, and being mostly self taught I've probably developed 'work arounds' to solve whatever issue they fix.
I've read the documentation and programmed a few test cases, but either for the interfaces I've developed or for whatever reason I've never ended up using them.

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 have a wrapper swf which loads the main content swf.I've been successfully hearing custom events in the wrapper swf dispatched from the main swf, but only if they're the kind like this:
Code:
// main
dispatchEvent(new Event("LOADING_CONTENT"));

Actually I wanted to know what is bubbling event and how to make use of it. Also, what is the concept of capturing, targeting and bubbling too?

I have a simple button class. When the button is pushed I'm triggering an event on the parent level. What's the best way to pass a parameter to that upper level event?

I have a movie clip (cover) which covers another movie clip (stuff).I have set up Mouse Over on the Cover movie clip so that when you mouse over it, it tweens off of the Stuff movie clip.Then i have Mouse out set up on the Stuff movie clip so when you mouse out of it, the Cover clip tweens back in..
Now when I mouse over a MC that is inside the Stuff movie clip..it triggers the mouse out for the Stuff movie clip. this is undesired.I need my mouse to be active inside the Stuff movie, so mouseChildren = false doesn't work,because i then can not click on things inside the stuff movie clip.Right now i have managed to work around this by running a loop for each child inside the stuff, adding an event listener and telling the tween to stop on those events,but this won't work for children of those children without looping again.. and the children of those children's children would need looped as well... The question is.. How do I make a child movie clip not trigger the mouse out for it's parent(s)?

I have a content clip that gets replaced by a movieClip from the library every time a button is clicked. Some of the content sections contain video. Within the video is a custom event firing that bubbles up through its parent clips all the way until it gets to the clip that was added to the stage on user click. It never goes beyond the content clip to the stage, where I need the listener. Isn't an event supposed to bubble all the way up to the stage? Why would it ever stop?The code is in 10 different places in 10 different files or else I'd post it.

I can't figure out why the event listener callback function isn't being fired when a child object is being clicked. Since the "SelectionPoint" object is a child of this class, shouldn't the listener get notified of the MouseEvent.CLICK event during the capture phase?
Code:
package {
import flash.display.*;

In IE, if flash has focus, and receives a keydown event, it does not appear to bubble the event up through the DOM (I can't capture the event by listening on document, however the same listener can capture key events from html siblings, so I know my listener is working).
However, some other plugins on the page (I am looking at you windows media player) still respond to key events that initiate in flash (and I need to prevent that from happening)! It seems that the key event initiated in flash takes the bubble express highway straight to the top (where the top is whatever is above document in the DOM hierarchy). I have tried terminating the events in as3, and tried different wmodes... neither approach works.

I have a MovieClip which contains 4 Buttons:When the user mouses out of the container, it shoulddisappear:this.resolutions.addEventListener(MouseEvent.MOUSE_OUT,this.resolutionsClose);When the user mouses out of any of the 4 Buttons, the event bubbles up to the container. This is not the expected behavior. How do I stop this propagation when none of the 4 Buttons have mouse out handlers?

"allows child clips to receive events despite the fact that a parent might make use of them as well, something not possible with the normal convention of handling button events where no child movie clip ever receives button events if a parent has any button event handlers defined for it." how to attach an event to an mc called "child_next" within "parent1".
Code:
import com.senocular.events.*
function handleEventMethod(eventObject:ButtonEvent):Void {
// trace event
if (eventObject.type != "onMouseWithin") trace(eventObject.type +"("+this+")");

I'm wanting to bubble events between a few custom classes, however, they are not Display Objects.Is there any quick and easy way to do event bubbling, without needing a display list?Or perhaps another way than needing to manually listen for each event that is attached and "relay" it every time it is dispatched?

It's like this: I got this .swf which takes a variable in the url, like: myswf.swf?id=1. I put it on my server and I embed it in a html-file on my server and it works fine. The swf takes the parameter(id) and it uses it correctly. THOUGH.. When I let some other person embed it in a html-file on their own server (you know, like you do with Youtube videos) it seems as if the swf doesn't get the parameter. If I run the html-file locally on my computer and links the <embed> tag to thesite.com/myswf.swf?id=1 it doesn't work neither, though if i link it to the local swf in the same folder it works fine. I don't get it, what's the problem here? Did anyone experience the same thing, and if so, did you solve it? How?

When the user clicks and drags across the movie, it changes frames--forward or backward according to which direction they drag. When they're on the last frame it should go to the first frame, and vice versa, if they're dragging in the associated direction.For some reason, there seems to be a minimum speed of mouse movement to go across this point, where it's not present to go between any other pair of slides.Here's the code:
Code:
stage.addEventListener(MouseEvent.MOUSE_UP, stopClick);
stage.addEventListener(MouseEvent.MOUSE_DOWN, clickStart);

In my workplace we are mantaining a lot of ecommerce websites,some coded better than others. On some of those, sometimes uncaught exceptions are thrown, and showed by the alertbox from the flash player debug (If you have it installed).To rise the average user experience I'd like to report all those exceptions throught a in house tool we already have.Is there a way to catch those exceptions?Maybe the flash player debug exposes them to javascript, or in some other way.

Consider this scenario we have a class A which is singleton it has a function Sum(a,b) ** . Now we have two classes **Class B and Class C respectively. Both classes (B,C) call add function and listen for a event.
Class A
{
function add(a:int,b:int):void
{
[Code]....
Similarly there is a C and D class. Now when lets say both classes call A's add function (when A is singleton) how does one insure that the right answer is returned to the right listener.
Secondly what if the calls are changing something, is there a locking in singleton?

Firstly I feel this question is not a duplicate for : Easiest implementation of onReleaseOutside in AS3?
Now, the problem , I want to do some action when the mouse_down happened inside the stage, but the mouseup happened outside it. e.g check google finance charts, try dragging the change range divider and then make the drag such that your mouse exists the browser screen, and then do a mouse_up outside the browser, this will trigger some action inside the stage , i.e make the range stick to the position it was, when the mouse exited the window.)

I know how to catch usual lowercase letters. I'm using KeyboardEvent.KEY_DOWN and compare the code to the ASCII table to find out which key was pressed. Now, I also want to be able to find out if there is, for example SHIFT+A pressed, and I have no idea how to implement this. I mean, in my program SHIFT and A are absolutely different keys which have nothing to do with each other, and they both will call KeyboardEvents when pressed. In Georgian alphabet some letters are typed by combination of SHIFT and English letters, for example W on Georgian keyboard means წ, when SIFT+W means áƒ. Absolutely different letters, as you can see. And I want to be able to catch both, coz I'm currently developing Georgian-language game.

I have a series of .swf files that I inherited from an old version of a site I'm trying to rebuild.
When flash_element.submitForm() is called, they POST some data directly to a static url ("/submit"), then depending on the response, reload the browser page.
I would very much like to capture the data that they POST using javascript - preferably without it getting sent at all - so that I can have more intelligent logic to handle to request/response than is built into the .swf files I've inherited.
Basically: When a flash object makes a http request, can I catch and cancel this event in Javascript?

i have written a class that is basically a bunch of faders that lets you drag your mouse along and draw curves. when you hold the mouse and go outside the movie clip though, you get lot's of reference errors. it doesn't seem to affect much, and for the moment i am just catching the errors with try / catch, and not responding to them. is this considered good practice, or should i try and track own the problem further, seeing as it seems t be working fine as-is?

I am having trouble with event bubbling when using the flash video player I've tried several methods to stop the player,before submitting here - but nothing I've tried seems to work The scenraio is: The site loads great - the buttons function correctly When the fourth button is click - it loads a frame with an embeded FLV player (the default vid player Flash uses when importing video into the swf) When the fourth button is click (Cheetah Coloring System)The video starts to play When any other button is clicked The video continues to play The embeded vid clip is named movie1 and i've tried using move1.stop(); but that stops the entire swf how to stop the movie - when another button is clicked?
COde used for the buttons::::
btn1_mc.addEventListener(MouseEvent.MOUSE_DOWN, bhp1DownHandler);function bhp1DownHandler(event:MouseEvent):void {gotoAndStop(15);}
btn2_mc.addEventListener(MouseEvent.MOUSE_DOWN, bhp2DownHandler);function bhp2DownHandler(event:MouseEvent):void {gotoAndStop(16);}
btn3_mc.addEventListener(MouseEvent.MOUSE_DOWN, bhp3DownHandler);function bhp3DownHandler(event:MouseEvent):void {gotoAndStop(17);}
btn4_mc.addEventListener(MouseEvent.MOUSE_DOWN, bhp4DownHandler);function bhp4DownHandler(event:MouseEvent):void {gotoAndStop(18);}

Environment:
Windows 7,
Internet Explorer 8,
Flash ActiveX 10.1.53.64,
wmode=transparent
Just wrote a small test page that you can load in IE and Firefox or any other Browser.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
[Code].....
So clicking any colored shape should produce an alert (except for the green one in IE, not sure why but I hope that's off topic and not related to my issue).
Clicking the Flash container in Firefox will work Perfectly fine. You should get alert boxes in this order containing: span, div and body. Flash bubbles the event to the HTML. But this is not happening in IE.
So why is Flash in IE not bubbling events to HTML?
Edit: As mentioned by Andy E this behavior can also bee seen in Google Chrome which to my knowledge is not using ActiveX to embed the flash movie into the page.

I have a utility class that I use to load images that never gets added to the stage and is extending EventDispatcher, it simply loads the data and spits it back out on request.
I want to add a custom event to track loading progress from outside the class. The events are firing but not (i think) bubbling because they aren't in the display list.
Is there a good way around this? I was thinking: Can I have a non display list object tell a display object to send the custom event for it?
