ActionScript 3.0 :: Dispatching Events In External Swf File?
Jan 22, 2009
I have problems dispatching events from an external swf file.
The class that loads the file only receives the original events of actionscript (for example MouseEvent.CLICK, etc) and ignores others that are dispatched with a own event class or dispatched with a direct string in the type parameter. For example:
dispatchEvent(new PLYPubliEvent(PLYPubliEvent._OVERLAY_OPEN))
dispatchEvent(new Event("testtt"))
These events are dispatched from the loaded swf file in the main timeline.

I have a main application Planner.mxml. This view has a couple of custom components, one of which is LoginView.mxml. In LoginView.mxml I do the following:
protected function btnLoginClick(event:MouseEvent):void
{
try
{
[code]....
As you can see, when the user is successfully logged in, I want to dispatch a custom event; if not, I show an alert box. However, this event doesn't dispatch (or at least, I don't know how to listen for it).
I would like to listen for it in my main application where I can then change my viewstate to the logged-in state. However, the event never seems to get there. I listen for it by having loggedIn="loggedInHandler(event)" on my loginComponent.

I have been trying to get a grasp on dispatching events and have a few questions I am hoping you will all be nice enough to clearify for me.
Do I have to have a custom Event class to dispatch a custom event?
If so do I have to create a new intance of the event each time I want to dispatch an event. Example:
dispatchEvent(new MyEvent(MyEvent.TASK_COMPLETE));
or can I just dispatch an event once an instance has already previously been created.... example: dispatchEvent(MyEvent.TASK_COMPLET);?

I am able to get the result, but not able to dispatch the event from the custom actionScript class. I googled and got the riposte that you need to add it to display list.

I have a custom event class public class FFTDrawEvent extends Event {

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 want to have a main logic class that listens for dispatched events from an assortment of other classes.
for instance: i have a parent Map class that contains X instances of a State class. When the user clicks on a State class, i want to dispatch an event CLICKED along with the name of the state.
now this Logic class will see this new event and process the name of the state and perform some other logic stuff. no matter what i try i can only get it to work where the State class listens for its own Dispatched event. Which to me seems a waste, i could have just manually called the function.
I have read so many tutorials online about custom events/ dispatching and they are being used in a basic one class example.

I have a key.addlistener setup to listen to key events.What I want to be able to do is to dispatch key events by for example a mouse click or just on load. I've tried a lot of possible solutions such as dispatchEvent with type as "onKeyDown" and "keyDown" etc.... but key listener simply do not treat it as a keyboard event.
Code: Select allvar eventObj = new Object();
eventObj.type = "keyDown";
eventObj.code = 13;
eventObj.ascii = 'e';
dispatchEvent(eventObj);

Basically I am trying to create a string Validator which requests a new language from its controller by dispatching an event upon its creation.
The example below is a straight copy from the Flex3 component explorer - the only diffrence being that I have created the validator as a custom component which dispatches an event upon its creation.
The problem is that my main Application cannot hear the event being dispatched and I don't know why.
Here is the example
MyValidator.as
package components

import flash.events.Event;

However, it seems to me as I've started building this (or trying, rather) that there's no way this can be done, but I'm sure I'm wrong. Since the static class is never added as an instance to the display list, the stage (or any object for that matter) will never hear any events it dispatches.I've searched and found this, but that doesn't seem to be the right solution since I'm listening for my custom LinkEvent event from the stage, and *not* in the class calling the dispatch function in the static dispatcher class.And to reiterate, the goal is to have a single class I can use throughout my application that dispatches my custom LinkEvent event with two properties: linkURL, and linkTarget.The whole reason for wanting to do this is so I can have some control over what happens (to track, or do some other behavior) when someone clicks on a link created within an htmlText TextField with an <a>

I am attempting to dispatch an event on the click of any of the buttons in a button array in the document class of my application. The intent is to have an external object receive this dispatch so as to remove a listener for the EnterFrame event in this class.
Here is the Main.as code (document class):
Code:

import flash.events.*;
public class Main extends Sprite {

`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.

I'm curious about event performance. I have a custom class that downloads files from a server and writes to your local system with AIR. This class has a few custom events that fire during a download process: File starts downloading, files finishes downloading, error occurred, progress, and a few others. This class was built for a specific project, but made coupled so it can be used for anything else wanting to download a file from a server. I'm starting to implement it into a new project, and a few events I'm not listening for, such as when the file starts downloading, or the progress of it, just the complete.
Does it strain overall performance having all the other events still dispatching, when I know they aren't being listened to? Would be be better to comment out the dispatchEvent() for the specifics I know aren't used, or does it even matter? There's obviously events dispatched throughout the SDK that aren't always listened for: Right click, drag, resize, etc. This makes me think it doesn't matter that these events fire but aren't handled, but since code is running and things are happening, that means there is performance going on.

Would it be possible for me to also dispatch non-custom events (like Event.CHANGE) from inside a class? I already did this with custom events which worked fine, but when I try to dispatch a the Event.CHANGE it will tell me that I am trying to convert a String into an Event (??). What I do is:[code]

I notice in actionscript 3 that when a handler gets called, its able to access the senders properties. If I dispatch an event from my custom class. can all the listeners inherit all my public properties and methods?

When dispatching events in as3 I always have to extend class from sprite, or movieclip, but when I don't have display objects I don't wont to extend to sprite or movieclip. What is the most light class that I can extend, I mean no display object, and still do use event dispatching?

In Adobe AIR 1.5, I'm using URLLoader to upload a video in 1 MB chunks. It uploads 1 MB, waits for the Event.COMPLETE event, and then uploads the next chunk. The server-side code knows how to construct the video from these chunks.
Usually, it works fine. However, sometimes it just stops without throwing any errors or dispatching any events. This is an example of what is shown in a log that I create:
Uploading chunk of size: 1000000
HTTP_RESPONSE_STATUS dispatched: 200
HTTP_STATUS dispatched: 200
Completed chunk 1 of 108

I think this is a pretty simply problem but I do not seem to be able to pull it off. Basically I have a parent class A, and a child class B.Class A instantiates class B with addChild.There is a shared object which is being updated from a java server (red5) that has an event listener attached to it in class A.I have a function in class A which will pass certain, specific updates from this shared object to class B.The problem occurs is that when class B is instantiated, the event listener from class A doesn't work anymore. I have not removed the event listener from A.?

I'm working on a project and had a question related to another thread I recently posted earlier this week regarding an area I was a little stuck on..While I did manage to resolve most of my issue, there's still a piece of the puzzle that's missing. I basically have one main container swf that loads several external swfs into a MC and cycles through an array of external files. I have navigation buttons so the user can click next to proceed through all of the external content files. My goal here, is to not have the "next button" become active until after the external files are done playing, so they can't skip ahead.
I currently have this working by having the external swf dispatch an event (from its final keyframe) to the main swf telling the main swf it's done playing, and then activates the next button on completion. This works great; however, I can't seem to get it to dispatch this event on any of the sequential swfs -- it only does this for the first swf initially loaded. Is there a way to "reset" the event to detect the end of the other swfs and continue in this fashion? Or another possible solution so I can apply this to each external swf?Here is the code I have in the main container swf:
Code:
//Array of external swfs
var contentArray:Array = new Array("content1.swf", "content2.swf", "content3.swf");

I'm trying to get an external swf to load when the flv content of another external swf finishes playing.
I've only been using actiosncript 3 for about a week and I've got to this point from tutorials, so my knowledge is limited.
This is what I've got so far:
Code for External swf (with flv content):
import fl.video.FLVPlayback;
import fl.video.VideoEvent;
motionClip.playPauseButton = player;
[Code].....
I'm starting to get an understanding of how all of this works, but it's all to new to me at the moment, so I'm sure I've approached it from the wrong angle.

I have a Main Menu swf with Menu selections. When you click on the Menu1 button it launches a separate swf file that will be doing allot of things. I have buttons, video etc. All with some sort of a addEventListener attached to them. Because the Main Menu is running and you have the option to select another button, which launches another swf, I am unloading the current swf. I can tell the video is still running in the previous swf because you can hear it. I use the SoundMixer.stopAll() and that stops the video. But what about all those addEventListeners?
This is what loads the external swf (Main Menu).
Lesson = external swf
var myLesson:MovieClip = new MovieClip();
addChild(myLesson);
myLesson.x = 205;
myLesson.y = 30;
[Code] .....
This is what unloads the external swf: I call this in a couple of places depending if the selection is in another external swf.
myLoader.unload();
I also have been noticing that the naming of instances is increasing allot in a few of my lessons. Don't know if that has an impact on anything or not. How do you control events running in a separate external swf from a Main swf or stop, remove them.

I have been trying to pick up more as3 lately, also have been converting some of my sites from as2 to as3. In as2 I could create 3 menu buttons and save them in a mc- lets call it menu_mc. This menu_mc sits on my main stage. I have also placed a mc on stage to hold anything that I load. Lets call it holder_mc. So I figured out how to get my email button to work using this:
email_mc.addEventListener(MouseEvent.CLICK, mailto);
function mailto(event:MouseEvent):void {
var email:URLRequest = new URLRequest("mailto:myemail@mail.com");
navigateToURL(email, "_blank");
}
That's fine. What I can't for the life of me figure out is understanding how to click on one of my menu buttons and load a swf into my holder_mc on stage. In as2 I could use this code on a button :
on (release) {
//load Movie Behavior
if(this.my_holder == Number(this.my_holder)){

I'm new to Flex and am having trouble understanding Events. I think Events are what I want to use for my situation. I have 2 components, addUser.mxml and listUsers.mxml. I access these from a ViewStack in my main application. When I load listUsers.mxml it shows a list of current users in a datagrid via a HTTPService call. When I add a user using the form on addUser.mxml I would like the datagrid in listUsers.mxml to refresh when I return to that view to show the new user. I've tried several different things with addEventListener and dispatchEvent but can't seem to get it working. Can someone help me with this logic?
