Actionscript 3 :: Force Program To Wait Until Event Handler Is Called
Apr 3, 2010
I have an AS 3.0 class that loads a JSON file in using a URLRequest.
package {
import flash.display.MovieClip;
import flash.display.Loader;
[Code]....
When the file is finished loading, the mapHandler event makes changes to the class properties, which in turn are accessed using the getMapWidth function. However, if the getMapwidth function gets called before it finishes loading, the program will fail.
How can I make the class wait to accept function calls until after the file is loaded?

I'm using Delegates in a new project I'm working on to call an event handler in my class with the scope of the class.
I'm having an issue referencing which button is calling this handler. Since all of my buttons are created dynamicly, this is a big problem.
I'm used to using forms and components where I had no problem with this and could reference who was calling the event handler by using - event.target
This doesn't seem to be the case with movieclips though, is there another way to do this?

I need to call FileReference.save() after a web service call has completed, but this method has a restriction: "In Flash Player, you can only call this method successfully in response to a user event (for example, in an event handler for a mouse click or keypress event). Otherwise, calling this method results in Flash Player throwing an Error exception." (from the documentation here)
This restriction is a bit vague. Does it mean that I can only call the FileReference.save() method from within an event handler function that is registered as a listener for certain types of user events? If so then exactly which user events are valid? (Perhaps there's an event that will never be dispatched by user interaction with my application and I could register an event handler function for that event type and make the save() call from within that function?)
My difficulty is that I can't safely call the FileReference.save() method until my web service returns with the data that will be used as the argument of the FileReference.save() method call, so the event that triggers the FileReference.save() call is actually a ResultEvent rather than a user event, and I'm leery of dispatching a new (faux) user event type in order to be able to trigger the FileReference.save() call unless it's definitely a user event that would never be dispatched as a result of actual user interaction with my application.
In a nutshell what I'm doing now is this: I have a function that is registered as a handler for a button click. In this function I make my web service call to fetch data from the server. I also have a result handler function which gets invoked when the web service call completes, and it's in here that I want to call the FileReference.save() method since it's at this point that I know that the data is ready to be saved to a file. But the aforementioned restriction is blocking me from doing this -- I get an error:
Error #2176: Certain actions, such as those that display a pop-up window, may only be invoked upon user interaction, for example by a mouse click or button press.
I've tried many things to get around this such as creating a second mouse click event handler function with the FileReference.save() call within and calling it after a timeout interval (to give the web service time to complete), but I keep running into the same error -- maybe that approach doesn't work since the second function isn't registered as an event listener for the event type used as its argument.

My program reads a rather large data file that is crucial to the display of the program I am making.I have an event listener that waits for my loader to load all data from the file, and it then adds all the data (and parses it) to a 2d array.Unfortunately the program flow doesnt wait for the loading to finish, so when it checks the array, it is still empty because nothing is loaded into the array yet.

I am using NetStream to play some .flv files on local disc. My code skeleton is:
public class AdvertisPanel extends MovieClip
{
private var _video:Video;
private var _connection:NetConnection;
[Code].....
I used some .flv files that I download from YouTube to test; and I found that the handler metaDataListener would not be called when playing some .flv files, but some would. Is the problem caused by the video file? Because I may resize the video before play it on the screen, and I really need to know its original width & height.

I am writing a flex application that has a MainMovie that loads flex programs (ChildMovie) depending on what the user selects in the MainMovie.
class MainMovie{
private var request:URLRequest = new URLRequest();
public function callPHPfile(param:String, loader:URLLoader,
[code]....
I can see that the callPHPfile function is being executed and received xml data from in httpFox, the problem is that the code in the handlerInChild function is not being executed.

I am trying to learn JavaScript and I am wondering whether JavaScript has a event listener just like ActionScript's ENTER_FRAME. Basically, I want this event listener to listen "all the time" not just wait for any particular instance (mouse click, keyboard event) of event.

I have a ComboBox with a label function like this one:
private function fieldLabelFunction(item:Object):String {
return resourceManager.getString('dashboard',"SS." + item);
}
When I change locales, the labels display correctly in the ComboBox's dropdown list, or if I change a selection. However, the currently selected item's label doesn't refresh at first. Is there a way to force the labelFunction to get called again?

I started making my first complex game and ran into a problem that made me just stop everything I was doing and I have laid the project to rest until I can find out how to fix it.The problem is simple. I have a timer in a public class. The timer is private, but the function to start the timer is public. Only one class calls it. But as soon as the program starts, the timer function executes.Now that aside, why are some public functions being called at the time of the program being executed? The class that executes the function isn't even called until later/instantiated.

I have an event listener for a custom event type. This custom event overrides the clone method as required.In this event listener I want to dispatch an instance of a different type of event... a different custom event instance altogether. It also overrides the clone method as required.The problem is I'm getting a type coercion error: TypeError: Error #1034: Type Coercion failed: ...I do not know what is trying to do the casting. My code is:
/* elsewhere in a method */
addEventListener(GestureEvent.GESTURE_SCALE, handlePinched);
/* the event handler */

I am writing a program that needs to go to a random frame after clicking a button. However, the program also needs to start on a random frame. When I call the function at the start of the program it gives me an 1120: Access of undefined property event error. The function is originally written as followed:
function randomMatchedTrial(event:MouseEvent) {
... lots of code that probably doesnt matter, but let me know if it does...
}
the program starts by calling the function as followed:
randomMatchedTrial(event)
Can event handler functions be called outside of the event listeners they are handling?

I rune the following code from TestClass:
ActionScript Code:
handler.loadFromFile("test5.txt");
dataset.generateComplete();[code]....
However, why does dataset.generateComplete(); get called before onFileLoaded(event:Event)?I can only assume that this is the case, as var pointList:Array = myHandler.getPointList(); returns Null, and when I run some tests with trace statements,I can see that onFileLoaded (event:Event) is seemingly called after generateComplete() Is the URLLoader process running in parallel to the rest of the application?

I have a button labeled 'blueButton' and I'd like to use an anonymous function to handle the click, like so:
blueButton.addEventListener(MouseEvent.CLICK, function(event:MouseEvent):void {
trace( "-----click detected-----" );
// now do other stuff
});
Problem is, the click handler is called multiple times per click. The number of times called seems to be random (sometimes 2, sometimes 4, sometimes 3 etc). could I be missing something in my code, or maybe I set up the button wrong?
also I noticed that it seems to always get called once on the first click. After the first click is when it starts getting called additional times, maybe that has something to do with it?

I have a child component that dispatches an event in Parent. The event in parent makes a call to our database. Right now, the event gets fired off & the child continues without the results. How do I make it so that the child waits for the results from the database b/f the child continues?
in child:
<fx:Script>
<![CDATA[
dispatchEvent(new Event("getDBcontents")); //
dispatch the event in the parent do some more stuff here but we need pause until we get the result from the parent

I am trying to write functions as efficient and reusable as possible. One function in particular I wrote was designed to easily create new objects from externally loaded files. The problem I have is that I can't think of a way to make the function wait for an event listener to complete before returning the desired object. Here is what I have so far and I will point out where the problem is.
Code:
var myNewObj:Object = loadFile(parentName, "swfs/" , "file.swf");
function loadFile(parentObj:Object, urlLocation:String, fileName:String):Object{
var fileLoader:Loader = new Loader();

I have an subclass that is called from the constructor of the main class. The subclass is loading and parsing a .xml file for images. A Event Listener is waiting for the .xml file to load and the fill the image URL's into an array. This code works fine (tested), but here is my problem.
While the subclass is called in the constructor, I also have code that should display two of the loaded images by default. However, while the xml file is parsing and filling the array, the main code already continues on and tries to display the two default images on the stage. But this causes the program to break, because the code executes before the array is filled from the .xml file.
this is the error the program spits out : TypeError: Error #2007: Parameter url must be non-null.using trace I see that it is trying to access the array but its undefined, because it hasnt been filled yet.
Here are the code snippets, concerning that problem.
//Main class code
//the constructor of the main code, which calls the loader class for the .xml
public function GameOfGames()
{
[code]....
Is there any way to make the code in the main class wait for the array to finish filling up before the main code moves on?

I want to extend my function to a better design to where I can pass a canvas object into so I don't have to write N functions.. I'm not sure as how to do this properly I've come up with a naive design with a switch but even then if I add another canvas I still need to write new code for the new canvas.
function fadeCanvasOut(event:TimerEvent):void
{
canvas1.alpha -= 0.1;

We (AS3 coders) all know that one of the great things about the AS3 event model is that handlers are scoped to their containing objects. I'm writing an EventDispatcher for JavaScript, and trying to achieve the same effect.My question could be answered in a couple different ways:A: How does ActionScript 3 set scope within an event handler to the handler's container object, rather than to the event handler's caller (the IEventDispatcher on whom dispatchEvent() was invoked)?

I'm using a progress bar component in a movie clip and this progress bar works loading an external movie clip. However, once the external clip is loaded, it seems the "complete" event is not registering with the object listener. This is what I have:
ActionScript Code:
this.createEmptyMovieClip("FOB", _root.getNextHighestDepth());
var progressBarListener:Object = new Object();[code].......
The code a little more complicated than this in that there is an array that stores some information and a setInterval command that calls the loadContent function loading each external movie clip. I can past the entire code if necessary.Also the progress bar component is set up as thus: in the main movie (root) there is a movie clip called progressBar. Within progressBar the component resides with a variant name of PB.For some reason, when the external clip is finished loaded, the progressBarListener doesn't seem to be called.

I'm trying to find a way that I can control how a flash movie handles the click event from the HTML page outside the movie.
I run a website where we have advertising space for Flash Ads provided by our customers which, when clicked, open their own website in a new browser window (i.e. target='_blank') - however this causes us a few issues:
1.) We want to track the success of their ads, so we give them a custom URL that their ad should link to instead of linking directly to their site. This URL logs the click before redirecting the browser to the customer's website.
2.) Often the flash files we get use GetUrl() which seams to trigger the popup blockers in IE 7 & 8.
These two points mean we have to provide them with the custom URL for them to include in their flash ad, and/or tell them how to set up the movie to handle the clicks in a way that doesn't trigger the IE popup blocker, and this doesn't make it as seamless as it should be to place an ad on our site.
So, what I'm trying to do is find a way that I can reference the Flash movie object with JavaScript (or similar), and set the click event to open up a specified URL - so if the customer's flash movie doesn't have the right URL set in it, or is triggering IE's popup blocker it doesn't matter because when we display it, we can modify the event handler to use the correct URL and to open up their website without tripping any popup blockers.

I'm editing an xml gallery.you can see how it works now here (thumbnails are different than images, cause it's just for the sake of testing now)[code]...
oki. this all works via for each loop which creates thumbnails dynamically. the event handler for the click on the thumbnail is inside the - also dynamically created via this for each loop - button over each thumbnail. more or less like this[code]...
and now: i'd like to add "next" and "back" buttons,so that the user doesn't always have to click the closing cross and go back to the thumbnails, but that he can also -once he selected an image - simply loop through the gallery image by image.
oki. so first i tried to get the name of the button clicked previously and store it in a variable, a thus this would tell which image should be loaded via loader (say, name instance56 means Image00002 was loaded, so if now user clicks next, Image00003 should follow) . but i'm simplytoo simple to get the variable out of the event handler and for each loop scope. i also tried to do it inside the event handler,but then it gets terrbily messy, and i can never force loader to load the right image.
