What is the difference between event.bubbles to false for any event, And Setting event.stopPropagaion() or stopImmidiatePropagation() while handling event? I am using flex4 with as3.
View 3 RepliesI 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?
View 3 RepliesI 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);}
I know the difference between the two, but I never felt the need to use the bubbling feature. If I want to listen to an event from a deeply nested children, I always use the capture phase. Could someone explain to me why I should rather use bubbling, its advantages, and maybe show me a situation in which bubbling would be the only solution?

Why we need to use event Propagation?
View 1 RepliesI have a movieclip containg several containers with other objects attached to them. Those containers have different levels of nesting. Now I want to add an EventListener to the top-level MovieClip and the called function uses attributes of this MovieClip. Because
of that I cannot just retrieve the MovieClip by saying e.target.parent but have to stop the propagation. I know there is a stopPropagation() method but I don't really get how (and when) to use it.
If I have sth like this:
function myResponse(e:Event):void {
//Things happening
} myMC.addEventListener(MouseEvent.CLICK, myResponse);
Where do I have to stop the propagation?
I have a container named circleHolder_mc. Inside I have four circles named circ0_mc circ4_mc. My goal is to have each circle blink on mouseover. The closest I've got is the following code which causes all of the circles to blink at the same time.
circleHolder_mc.addEventListener(MouseEvent.MOUSE_OVER, onBlink)circleHolder_mc.addEventListener(MouseEvent.MOUSE_OUT, unBlink)
var timer:Timer = new Timer(1);timer.addEventListener(TimerEvent.TIMER, onTimer);
function onTimer(evt:TimerEvent):void{ alpha +=7;}
function onBlink(evt:MouseEvent):void{ timer.start();} function unBlink(evt:MouseEvent):void{ timer.stop(); alpha = 100;}
how event propagation works in PV3D its definitely not like the conventional Flash style. On a quick search i have been able to find out that its possible using the InteractiveSceneManager Class, but unfortunately

View 3 RepliesI'm using Event Propagation in order to change the alpha of each Child on MOUSE_OVER, MOUSE_OUT, and MOUSE_DOWN using... evt.target.alpha On OVER the Child's alpha increases from 0 - 0.5. On OUT it goes from 0.5 - 0. On DOWN it goes to 0.5 and stays there even with a MOUSE_OUT. What I'd like to do is then add a button to the main stage which takes the visibility of all Children back to 0, a basic type of Clear button.
I have one way to do it where I list each Child in a function (all 9!). But can I re-write this so that all Children are effected writing so much code? Ideally I'd like to send a request to find the number of Children (9) and then use this variable to write a function which says (where 'n' is the Instance name of each Child) that n(0-numChildren).alpha = 0

I have just learnt about event propagation and have made a few successful tests. However, I have encountered a problem when trying to use event propagation with several MovieClips that are masked and nested in a movieclip. The display list like so:
hd_cont > cndMask > cndThumbs > 9 movieclips with instance names box0, box1, etc etc.
I am attempting to scale the 9 movieclips at the bottom.
So I have tried:
Code:
hd_cont.addEventListener(MouseEvent.MOUSE_OVER, boxGrow);
hd_cont.addEventListener(MouseEvent.MOUSE_OUT, boxShrink);
function boxGrow(e:MouseEvent):void {
TweenLite.to(e.target, 1.5, {scaleX:1.5, scaleY:1.5, ease:Strong.easeOut});
e.target.alpha = .5;
[Code] .....
But when I reference the cndMask I get a
Code:
TypeError: Error #1010: A term is undefined and has no properties.

message in the output panel.
I have a custom TitleWindow component that is registered to listen for keyboard events from the user (so that esc closes the window, enter saves, etc.). However, in my testing I've found a couple cases where my keyboard event handlers don't fire. My best guess as to why this is happening is that there is some child component somewhere that has stolen focus and is stopping the keyboard events from propagating.
Unfortunately, due to the large number of components in my TitleWindow, I have no good way of knowing who has stolen the focus. My question then is, are there any good tips / techniques / tools for debugging focus issues and event propagation in Flex? Basically, I need something that will tell me who has the focus at any given time and who's handling an event at any given time... is that possible?
I have a Canvas (lets call it the Drop Box) which users can drag and drop external files onto. Next to this I have a ViewStack, of which one of the layers is a Canvas with a TileList. I have successfully managed to code it so that the items dropped onto the Drop Box appear in the TileList. I simply capture the darg drop event (lets call this event A) and dispatch a new one that the TileList is listening for (lets call this event B).
However, this only works if the ViewStack selectedIndex is set to that of the Canvas with the TileList. If the Canvas with the TileList isn't selected then the event listener which is added to the TileList at CreationComplete level (event B), won't be called until after the drag drop event has dispatched (event B). This means that something is firing before something even has a chance to listen for it!
I've tried looping until the Canvas with the TileList is completely drawn, but this causes the app to hang.
I've also tried passing the event to the Canvas and storing it locally, but when I attempt to access the clipboad of the event I get an error (dead clipboard).
Effectively I want to only dispatch the event to the Canvas after it's had a chance to load, and add the event listener to the TileList.
What is event bubbling in Flex?
View 1 RepliesActually 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?
View 2 RepliesI have a custom component made up of a selectable control (radio button)and a text input. I want to perform some logic in response to the change events from both of those controls, but after that I want anything that is registered on the composite component's change handler to have a change to handle the events as well. The problem is, when I re-dispatch the events the event target has changed to my custom component, losing the originating event's target.
Here's my custom component:
<?xml version="1.0" encoding="utf-8"?>
<mx:HBox xmlns:mx="http://www.adobe.com/2006/mxml" label="{listItem.@text}" data="{listItem.@level.toString()}">
<mx:Script>

In the event handler that receives change events from this component, I see that event.target is an instance of SpecifyRadioButton, not the TextInput or RadioButton, as I'd expect. How should I propagate the event to get what I want here?

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.
View 3 RepliesI 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?

I have a couple of Sprites on my screen and I want to write a single event handler to handle the double click on any of those Sprites. The following approach works for every event type except DOUBLE_CLICK:
[Code]...
To make it work, because in my application I will have lots of Sprites. In my opinion, a single event and the target property are more efficient than hundreds of event listeners. Am I right or should add event listeners to every Sprite?
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.
"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".

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?

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.

View 0 RepliesI 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?
I have searched on the Internet and didn't find any clue on how to do so, any idea ? I don't want flex only flash (my objects are not visual components).
View 3 RepliesI want to dispatch a MouseEvent.CLICK to a DisplayObject manually and make it bubble through all of it's children. The event is handled in the object that I dispatch it to, but does not seem to bubble (even though I specify that it should). Is it not possible to do this?
Code:
_targetObject.dispatchEvent(new MouseEvent(MouseEvent.CLICK, true));
Code:
private function handleClick(event:MouseEvent):void
{
This method is executed, but no children will receive this event.
