ActionScript 3.0 :: Send Event To Child?
Feb 19, 2007
Is it possible to send a custom event to a child?
[Code].....
when I click the parent, it gets click event. in the click event handler, the parent dispatches a custom event of type E. and the child is listening for E. obj.dispatchEvent() by default targets for obj it is called from. So, the event being dispatched won't reach the child if obj had one. Is there a way to send an event from parent to child? Better yet, is it possible to send an event to an object not in the DisplayList nor is a DisplayObject (the object is instanciated, but it doesn't have graphical role in the program)?

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'd like to send a dispatchEvent to a loaded swf, put into a movieclip. I found a good topic about it : as3 - dispatchEvent from a parent swf to a child swfi have a main.as
another class : submenu.as, that i import in main.aswhen i click on the "main" menu in "main.as", i would like to send a dispatchEvent to submenu.as (because i'd like the submenu to change one of its item, when i click on the "main menu" in "main.as", so i need to send a dispatchEvent to submenu.as) so i put a dispatchEvent in the method "clickButton" in my main.as : "Event.CHANGE"and in the submenu.as, i'd like to listen to this event.CHANGE, and that's what i wrote below ;-)

I'm trying to build a class for objects in my prog that can by manipulated in various ways.. I want right clicking them to send them to back, and left clicking, bring them to the front.
ActionScript Code:
package {
import flash.display.MovieClip;
import flash.events.MouseEvent;
[code]....
When I run it, however, I get ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.So something's not lining up, but I'm not sure how to write it so it'll work.

What I want to do is to remove an item from the array targetArray when the tween hitFade has finished. I added a MOTION_FINISH event to the hitFade tween which calls the spliceTarget function. I wanted to send an argument to the function indicating the targetArray index to splice, but apparently I'm not allowed to send any argument.
how do I send the targetArray index (i) along to the spliceTarget function?
I'm guessing that I could put i into a global variable and use that in the spliceTarget function, but that seems kind of roundabout.
Code:
var hitFade:Tween = new Tween(targetArray[i], "alpha", Strong.easeOut, targetArray[i].alpha, 0, 1, true);
hitFade.addEventListener(TweenEvent.MOTION_FINISH, spliceTarget);

Relative newbie with AS3 but I need to make an onscreen keyboard for a touchscreen. Through some searching and coding I have a keyboard object that can send events based on clicks but I'm not sure how to go that "last mile" to trigger an actual keyboard event so the selected TextField gets updated.

I am in the final stages of building my new web site: http:[url]....On most of the pages in the portfolio there is a video "Commentary" link (top right corner).Each of the commentaries are flv called up by f.ex:
myMCL.loadClip("http:url.....);
Once the video is done playing, it fades to black.I would really like the flv to trigger an event to send the playhead to another frame and load another swf.I could use a pause command and let the main time line pause so many milliseconds and then proceed, but it is probably not consistent how long it takes each viewer to download the video and watch it.

I'm having an issue with an event dispatcher and an event listener. Here is the application code...
Code:
Select allpackage {
import flash.display.MovieClip;
import flash.events.*;
import flash.net.URLVariables;
import SendAndLoad;
public class Test extends MovieClip {
[Code] .....
It will trace the loader.data variables but doesn't dispatch the event to the main application (Test). I'm listening for the event on the stage of the main but it doesn't trigger the event to display that the login has been successful even though it traces from the sendAndLoad class...

I have a game with two joysticks and I use the dispatchEvent command to send the fire button event. What would be a good way to send the number of the joystick to check who pressed the fire button. A bit dirty way would be to save just the number in root or in my main class.

I came to the point where I need to communicate between 2 objects (let's say Tank and the Cannon). It is tile game, and when the Tank approach specific tile I need my Cannon to shot the Tank. When Tank gets that specific tile I want to dispatch some custom event and have listener in Cannon class body to make the shot happen. Other way I would have to check in ENTER_FRAME loop (inside Cannon body class) if the Tank touched tile that runs the Cannon shooting - but this is not elegant and efficient. The issue is complicated by the fact that the Cannon and Tank are added to the Engine (document class) and can't simply hear for each other, because they seat on the same level in display list.
Initially I could addEventListener to the Engine, but this way my document class would enlarge to the XXL size (all listeners functionality, all methods for game etc). What I would accomplish is to have event listener in every Cannon object (defined in body class) listening for Tank's dispatching the event. I saw some 'Centralized Event Manager' article in the net, but can't download full classes [url]...

I'm trying to place an event on a child and not the parent but it doesn't seem to trigger the event. Example.
Code:
parent.child.buttonMode = true;
parent.child.addEventListener(MouseEvent.ROLL_OVER, onMouseOver );
private function onMouseOver(evt : MouseEvent) : void{
trace("child = "+evt.target.name);
}
The above event is not getting fired.

I have a child swf that dispatches as custom event:
dispatchEvent(new ModuleUpdateEvent(ModuleUpdateEvent.UPDATE_STRING, topicName));
My parent swf is listening for that event.
override protected function moduleLoaded(event:Event):void
{
_laoderInfo = event.target as LoaderInfo;
_laoderInfo.content.addEventListener(ModuleUpdateEvent.UPDATE_STRING, onUpdateFromModule);
}
When I trace/debug out the _laoderInfo.content it clearly says it is the child swf that was loaded in. however my listner function never fires.

I'm trying to do now is to make the application auto click on the first thumbnail,[code]I've been trying to google it and found that maybe I'll have to add an event listener to know when the thumbnail is actually being added to the stage, and just then click on it.I just found out that the code that Ascension Systems provided worked, but it didn't work at first because of a different error I had,the thing is, I'm working with the youtube API, FLVPlayback and such,And Each one of them is in a different movieclip,In the youtube movieclip I added this function:[code]I am setting the player as an object in the beginning of the script like so:var player:Object;

I am trying to do is to add an eventListener to a MovieClip that is inside another MovieClip. Things are going like this:I have ParentMovieClip and inside ChildMovieClip. When I load ParentMovieClip I would like to add an EventListener to ChildMovieClip so that when I roll over the mouse on the ChildMovieClip it will play some scenes from the ParentMovieClip.

I got a square component inside a canvas which when clicked shows a glow effect-indicating selection-while clicking somewhere else this effect is removed-indicating deselection.The problem is that the canvas always dispatches the "deselect" event, even if the mouse if over the square.I worked around this by defining a circumstantial function which removes the child's width,height from the parent's "clickable" area.Is there a better way to tell the canvas to dispatch his event only if not over the child ?

I 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.
at Bubble/init()
at Bubble()
at BubbleBuster/addBubble()

I have created a button class which has graphical elements. In future I might want to add this as a child to other things so what I would like to know is, firstly, can I get the details of the parent object from the child and, probably more importantly, is there an event that tells me when my button has been added as a child so that I can resize it?

I have two classes in my project - a main class and a fancyText class. In main I create a new instance of fancyText and add it to the stage. Inside fancyText there is a timer that runs and when x time is up the fancyText fades out.
I'd like to know the best way to remove the child from main when the alpha of fancyText hits zero. Should i go down the route of adding a listener to fancyText in main, and dispatching a custom event from within the fancyText class?
I guess i could just check the child's alpha value in main and remove it when the alpha it's zero. But fancyText only gets added in a certain scenario - so i can't check it all the time - which would mean doing something like this:
Code:
...
addChild(fancyText)
checkFancyText = true (assuming a boolean declared earlier)
...
elsewhere in main -
[Code].....
Seems like there are a number of ways to do it - I don't suppose it's possible to remove a child from main from within fancyText class? or is that space cadet talk?
