For example:
for(var i:int=0; i<someArray.length; i++)
{
var loader:Loader=new Loader();
loader.load(new URLRequest("http://testurl.com/test.jpg"));
[Code]....
The second paramter (i) for imageLoaded is always 1, I guess because i no longer exists and is defaulting to 1. Is it possible to get that second paramter to be evaluated when the load is started rather than on complete?
Forgive me for this stupid noob question but I want to call a function (loadList) that originally gets triggered after a mouseevent from another function (addToXML) that does not have an event.
The loadList function takes info from a XML var, sticks it into an array which then gets loaded into a tile list and that is working fine.
The addToXML function when called adds elements to the XML var after which I want to call the first function with the event parameter so it refreshes the items in the tile list.
I know it can do this by creating a new array and loading that into the tile list in the addToXML function, but it be much simpler to just recall the function.
I have tried things like
Code:
addToXML.addEventListener(Event.COMPLETE, loadList);
but all the event constants I have tried give me error messges like "1061: Call to a possibly undefined method addEventListener through a reference with static type Function."
I'm using an HTTP request to download a image in binary format. When the downloading is complete, I want to process it, but I also want to pass the image's ID to the complete handler function.

I am running flex with BlazeDS. My backend is in Java.
I have the following function in actionscript:
override public function execute():void
{
super.execute();
var responder:CallResponder = new CallResponder();
[Code].....
In actionscript3 how do i pass an parameter with an event call. when i use dispatch.
like dispatchEvent(new Event("Loaded", myvariable));
I created an image uploader for an app I am working on. I first used php for the server side script, and everything worked fine. I found out afterwards I had to use .net, so I created new serverside scripts. The problem I am having is that my event.COMPLETE listener is never firing. I can receive data back using a DATAEVENT listener, but then it stops at this error:
Error #2044: Unhandled IOErrorEvent:. text=Error #2036: Load Never Completed.
Here is how I am sending my file.
var fileRefReq:URLRequest = new URLRequest(FILE_UPLOAD_TEMP);
var fileReqVars:URLVariables = new URLVariables();
fileReqVars.subdir = "Temp";
fileRefReq.data = fileReqVars;
fileRefReq.method = URLRequestMethod.POST;
fileRef.upload(fileRefReq);
The file definitely gets uploaded to the first TEMP directory, but then it breaks with the above error.
In our app, I am periodically noticing that a particular event handler is not firing. 99% of the time, it works fine, but, every so often, it just dies. How can I find out whats happening? Is the DispatchEvent() not happening/working somehow? Is my listener still listening? Did something else catch the event, and not pass it along so that the 'right' listener can get to it ?
Here's a little bit of the code...
Thats a somewhat pruned down version of what the real code is, but I don't think I trimmed out anything important. The key, as I see it is that we fire up the params dialog, then start to listen for the closed event. Then, we show the param dialogs close function. What happens when it fails is that the trace message "caught close event.." is never generated, and, consequently, the closeHandler is not getting called at all.
fileReference.addEventListener(Event.COMPLETE, uploadCompleteHandler);
private function uploadCompleteHandler(event:Event):void {}
Above is one way to add an event listener in Actionscript. By default the callback function needs to have an argument with name event and type Event. Is there a way to declare this function without any arguments :
private function uploadCompleteHandler():void {}
Edit : It's possible to add an event handler without any arguments in mxml. So one student wanted to know, why isn't it possible to do the same in actionscript?

In as3, I am adding event listener and then attaching the anonymous function to it:[code]Now this whole piece of code is looped n times. Now, I have n myBoxes and whenever I roll my mouse over the box, it should alert the name. But, what I see is that the last value of count is used by each box. How can I pass parameter or value to the anonymous function? ( as roll over , I believe, expects only one variable)

I have a custom component written in action script (no UI). I am instantiating this component in an mxml file which is present in a library project. The custom component has a constructor which takes one argument. The library project is used in some other web project from where i pass a variable to this mxml file.[I have linked source of the web project to source of library.].
I have a static variable in my library project which holds the reference of the current object of the project. I need this static variable in order to use properties present in the mxml file. I am unable to use the property sent from the web project in the constructor of the custom component, but able to use the same in some other function present in the custom component.
I have the code:
var timer:Timer = new Timer(milliseconds, repititions);
timer.addEventListener(TimerEvent.TIMER, callback);
timer.start();
and if a user click I want to call the callback early. Is there was a way to either force the timer to finish immediately, or stop it and send the TimerEvent.Timer on my own?
I'm looking for something simple like the tween classes fforward().
EDIT
The Solution was
timer.dispatchEvent(new TimerEvent(TimerEvent.TIMER));
I was trying to do timer.dispatchEvent(new TimerEvent("TIMER")); which doesn't work.
I have found out that one can use an extra parameter in the embedding in order to load another xml other than the default xml file:<embed src="veppa_photo_album2.swf?xml=path/to/custom.xml" ....</embed>I was wondering how i can read this xml file in flash.
View 2 RepliesThis might be more of a subjective question, but is it generally best practice to have one dedicated method per event-types that you add an event-listener?
Such as:
myButton.addEventListener(MouseEvent.MOUSE_OVER, onMouseOver);
myButton.addEventListener(MouseEvent.MOUSE_OUT, onMouseOut);
//Somewhere else in the code...
[Code].....
And if you had a MouseEvent.MOUSE_UP, MouseEvent.MOUSE_DOWN and other relevant MouseEvents event-listeners to watch for, you could even set a switch statement to handle all the various MouseEvent types.
I'm working with arrays in AS3 and some of the utility functions described in the livedocs such as filter() or some() would be very useful to me, if only I could pass parameters to them...
Actually, I cannot find a single example of the use of these functions with custom parameters passed to their callbacks. Everywhere, it is always used with constants ! E.g. on this page: [URL]
var arr:Array = new Array();var totalElements:uint = 100;for(var i:uint = 0; i<totalElements; i++) { arr[i] = Math.round(Math.random()*100);}function isLargerThan90(element:*, index:int, arr:Array):Boolean { return element > 90;}var highestNumbers:Array = arr.filter(isLargerThan90);trace(highestNumbers);
What I need is a kind of "isLargerThan" function with "90" as an argument's value, not as a constant. Something like
function isLargerThan(element:*, index:int, arr:Array, param:Object):Boolean { return element > (param as Number);}I find it very odd that I cannot find no mention of the way to do this on the whole WWW, because that makes these utility functions absolutely helpless in many many cases and programming with arrays a real pain...

What is the difference between :
giving a function reference in the result attribute of the HTTPService class like this :
protected function httpserviceCheckUpdate_resultHandler(event:ResultEvent):void
{
var version:Number = event.result.text.version as Number;[code]....
If both of them are same then how can I provide the event parameter using the second approach (as written in the result attribute of the httpservice class)? Which one of them is the better way of doing things in FLEX.
how to write a callback instead of using an event to communicate between two classes (objects) in Actionscript 3.0?

View 2 RepliesI have been experimenting with supplying better debugging information when an error happens in asynchronous code in AS3.
As an example of the poor error reporting be default, take the case where I force a null pointer in a Timer callback (github gist), I get the following stacktrace back on the console:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at Function/<anonymous>()[/[path-to-source-file]/TestClass.as:14]
at flash.utils::Timer/_timerDispatch()
at flash.utils::Timer/tick()
This tells me very little about how the timer callback actually links to my code.
The question is: How can I get information about what code created the callback?

I have a TextArea that I don't ever want to be scrolled. When scrolling within the application that holds this TextArea, however, the scrolling stops as soon as the mouse ends up over the TextArea.
Is there any way to pass the scroll event to the application, or tell the TextArea to not claim the event?
I rarely use NetStream or any video in my projects, but someone I email with was wondering this, and I have no earthly idea.
Is there any reason why the NetStream's "onMetaData" event cannot be listened to using addEventListener, but instead requires you to use a callback function?
Is it faster, avoiding the overhead of events? Is it to prevent more than one listener being attached?
I have a full screen flex application and I want the user to be able to scroll using browser scrollbars. I don't need mousewheel in the flex application and flex appears to block mousewheel events within itself. So mousewheel events do nothing.
