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?
View 1 RepliesI 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 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 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.
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>
View 1 RepliesThis happens to be a really difficult question to ask.And maybe the answer is terribly simple and I have simply overlooked it. Happens all the time. ay you have a non-visual class (one that does not reside on the display list). This custom class, thru composition, will have a property that is a visual class that DOES reside on the display list. This custom class will also implement IEventDispatcher. So how do I do this:
Code:
public class MyNonVizClass implements IEventDispatcher

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]
View 2 RepliesIt is possible for a class to extend an arrayList of objects in Flex?
[Code]....
So, events bubble up the display list. That's great if that's what you want. But what if you have objects on the stage that are not related that need to listen for events from each other? A simplified example:
var objA = new ObjA;
addChild(objA);
var objB = new ObjB;
[Code]....
Object B can listen for events dispatched by object C. But I also need object A to listen for events dispatched by object C. Also, these objects are created in different classes so I can't hard code references to each other.
i have 2 sprites on stage. bottomSprite is added to the display list first, followed by topSprite. topSprite partially covers bottomSprite.i've added an event listener to bottomSprite for MouseEvent.MOUSE_MOVED notifications to simply trace the mouseX and mouseY coordinates. however, the notification doesn't work for the parts of bottomSprite that are covered by topSprite.
var bottomSprite:Sprite = new Sprite();
bottomSprite.graphics.beginFill(0x666666, 0.5);
bottomSprite.graphics.drawRect(150,150, 150, 150);
bottomSprite.graphics.endFill();

I want to handle the mouseevents for all the sprites on the stage including the one those are hidden behind (or overlapped or occluded) and the main condition is that I want to handle the occluded sprite (that hidden behind other sprite). example, say I have sprite1 and sprite2 on stage and I want to start drag whenever i click on the sprite and stop drag after another click.
This can be done easily, but the problem and my main requirement is that if I drag the sprite1 and drop it exactly on top of the sprite2 then sprite2 will be hidden behind the sprite1 I wont be able to drag the sprite2 without moving the sprite1 first. if you have played zynga's empires and allais game on facebook, it is handled seperatly, it is how it works in that game, the mouse event is triggered on the sprite behind the overlapping sprite, if you have two sprites overlapping one sprite than the mouse event is triggered on the sprite which is last and not the one in front irrespective of whether there is only one sprite overlapping or two or three and this happens to irregular shaped sprites (not just rectangles)
Im trying to dispatch and event from an XML class.dispatchEvent(new Event (XMLClass.INDEX_CHANGED));and catch it in the display class [code]I know that im missing something because the application works and the function runs but its not dispatching the event the event or maybe it's not catching the event in the display class, even though everything else is working and im not gettin' any errors.
View 7 RepliesI 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 have a custom event class public class FFTDrawEvent extends Event {
public static const DRAW_EVENT:String = "drawEvent";
private var _param:Array = new Array();
public function FFTDrawEvent(type:String, __param:Array, bubbles:Boolean=true, cancelable:Boolean=false) {
_param = __param;
super(type, bubbles, cancelable);

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);
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.
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;

`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.

View 2 RepliesIn 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

I have an app that displays XML as items. I am taking the createLayout() and trying to create a class that i can call from my custom component rather than having tons of code in the same file. The issue i am having is that when i call it, and run/debug, the display objects (text,links,date..) all have their visible property set to false. This happens even though I set the property to true in my code.

I am using CS3. And this is all about understanding Identifier and Class from the symbol property under Linkage.
I read some articles where all are using class instead of attachMovie() method on TimeLine.
Its confusing to me and couldn't able to make it work.
The article I read says that attachMovie() method will be in class file.
