Javascript :: ShowSettings Callback In Flex?
Mar 24, 2010
I am pretty new to flex, so forgive me if this is an obvious question.Is there a way to open the Security.showSettings (flash.system.Security) with a callback? or at least to detect if it is currently open or not? My flex application is used for streaming audio, and is normally controlled by javascript, so I keep it hidden for normal use (via absolute positioning it off the page).
When I need microphone access I need to make the flash settings dialog visible, which works fine, I move it into view and open the dialog. When the user closes it, I need to move it back off the screen so they don't see an empty flex app sitting there after they change their settings.

I have a Javascript API, which should be usable with GWT and Flex. Using the FABridge it is really easy to call Javascript methods from AS3 and vice versa. But when I try to register a callback to an AS3 method in my Javascript API I get stuck. Here is a short code sample:

My web application pass a javascript object to flex application using addCallback function.
when the flex application is in modal dialog in safari browser, the object in the flex application is null and when I open the flex application just in a new window, the object is passed correctly. But, I need the showmodaldialog to show the flex application.
The flex code:
ExternalInterface.addCallback( "handleEvent", handleEvent );
override public function handleEvent( event:Object ):Object {
Alert.show(String(event)); .....

I have a flex app and I am adding a callback method like this:
private function init():void
{
ExternalInterface.addCallback( "playVideo", playVideo );
}
[code].....
However if I uncomment and run the alert first. I get no error and it works perfectly.My first thought was that the alert was buying time until the script could execute, so i tried to run the script inside a setTimeout() but did not work.

I'm making a callback from javascript to a method on my swf. It works in Firefox with no problems, but in chrome the second parameter that's passed is always received as null? I've debugged my javascript and found that everything is working fine and the two values that are passed to the swf are correct at the point where the callback to the swf is made. At first i thought this might be a cross domain issue, but have ruled that out as if it were the case then the method on swf would just not be called at all. The second value is a binary string representation of an image and the length of the string that is passed is 101601, so i'm wondering whether there's possibly a limitation on the amount of data that can be passed? The first parameter is a much smaller string representing the file type and this always gets received successfully.

I have a Flash movie embeded with swfobject in a html container. Through ExternalInterface I have registered a javascript function to fire callback to my flash app.
ExternalInterface.addCallback("notifyClose", notifyOnClose );
The javascript function is added as an event listerner to fire onbeforeunload.
<script language="JavaScript">
function getSWF(movieName) {
if (navigator.appName.indexOf("Microsoft") != -1){
[Code].....
I have tested in FF and IE. Firefox works as expected but not in IE. In IE I get notified in Flash with the onload message, but not onbeforeunload.

I'm trying to get javascript to talk to flash, but I haven't been able to get it to work.I've gotten flash to talk to javascript, but not the other way around. It seems as thought flash isn't listening to the javascript, or I'm doing something wrongPart of the AS3 to initially call the js:
ExternalInterface.call("showGal", slastSelectedNumber);
The js i'm trying to use is:
function showGal(dPicture) {
document.getElementById('fullsizegallery').style.display = 'block';
document.getElementById("flashGalleryContent").someFunctionName(dPicture);

I have a page that uses the jQuery.swfobject plugin to embed 5 flash items into a page and each flash item has a callback using externalInterface. The callbacks work when I have the js function outside of $(document).ready(function() but the jQuery animations do not fire - the ajax load however does. Does anyone know how to get the animations working too, code below:
function pageLoader(galID) {
$('#menu').hide();
$('#holder_gallery').load("feeds.php", {gallery: galID}, function(){

I have a flash application using callbacks to javascript functions (eg. when it receives some data over a socket, it'll call a js script which would change the content of a div according to that given data).
Afaik, there is no actual mutual exclusion in javascript so I'm not sure if I can/need to simulate something like :
[code]...
So, the question is, when are those callbacks called ? Are they simply queued to be executed right after the browser finishes its task or are they triggered randomly ?

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.

In Flex, I'm making a set of asynchronous calls:
service.method1.send().addResponder(responder1);
service.method2.send().addResponder(responder2);
service.method3.send().addResponder(responder3);
I want to execute some code after all of these service calls have returned (either success or failure, I don't care which). How can I do this?

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?

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?

I have a Group screen component with some Path elements inside. The Group has a (default) style, and the Path has a (default) stroke. When the program starts, (on initialize) loads from a server (via HTTPService) some data that includes different styles for the Group, and it may also include different color/width for the Path stroke. If the styles/stroke attributes are not included in the server response, then the component will be shown with the defaults.

for some reason, whenever I dynamically load a swf on a $(document).ready() by writing to a div, I am unable to make javascript calls to the browser. Specifically, all calls to the browser return "null". This does not occur when embedding the swf normally on the page load, but I would like to prevent loading of the swf until a specified point in time.
What the heck is going on here? Is there something special about dynamically embedding a swf that prevents the swf from talking to the browser? The methods ARE called (I've proven such by showing alerts), but all return values to any function, regardless of type returned, shows as null when it gets to flash.

We're currently building a Flex application using the PureMVC framework with a shell.swf which loads/unloads modules dynamically. We're experiencing issues with memory and we're looking to replace the shell.swf with a JavaScript-based loader.Two questions:What would be a good framework to dynamically load the Flex components and allow the modules to communicate between each other?Would dynamically loading/unloading the modules via JavaScript take care of the typical memory problems associated with Flex/Flash applications?

I did some work that used Flex datagrids previously. It was smooth for the users and developers alike.
In my current project, I have to implement the same grids but not using Flex / Flash.
I have taken a look at extJS and YUI but they don't seem to measure up.
Are there other packages I should be looking at ?

I am integrating a flash module with Drupal using XMLRPC module. I am currently calling a node.save on Drupal(which creates a page in drupal), using Actionscript 2.0. On a flash button click, I am currently calling the node.save function. But ideally, I would like the function to be called first and only after the success of node.save, forward to the confirmation url. Right now, I am being forwarded to the page even without node.save being completed. I then have to refresh the page in order to see the results.
