Flex :: Overloading Event Handler Possible?

Jan 20, 2010

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;

Flex :: Event Handler Execution Order?

Jun 23, 2009

I have been trying to understand the way ActionScript's events are implemented, but I'm stuck.I know that AS is single threaded, which means that only one event handler will be executing at a time, and also means that handlers will be executed in a deterministic order*.For example, consider the following code:

1: var x = {executed: false};
2: foo.addEventListener("execute", function(){ x.executed = true; });
3: foo.dispatchEvent(new Event("execute"));

Flex :: F5 Refresh Event Handler Does Not Work In IE8?

Aug 4, 2010

I have an issue in handling the F5(Refresh) option in IE8 using FLEX. As i got some code by surfing..which is as follows

public function handleKeyDown(event:KeyboardEvent) :void
{
display.text = "Key was pressed: " + event.keyCode;
}
]]>

The main intention of the code is to handle F5(refresh) event. It works fine in Mozilla, GoogleChrome but not in IE8. When i execute the code in IE8 before the event handle by the FLEX the browser is handling the event.

Flex :: 3 - Invalidation In Show Event Handler Breaks Lifecycle

Oct 20, 2011

Create a tab navigator (or viewstack, whatever) and add a couple tabs. On your tab add a show event handler. Inside the event handler call invalidateProperties() and invalidateDisplayList() on one of the children of your tab. Put a break point on the childs commitProperties() and updateDisplayList(). You'll notice that the updateDisplayList() gets called before commitProperties() which results in incorrect behaviour.

I noticed this problem when setting a DataGrid's dataprovider from inside the show handler. Setting the dataProvider causes the grid to invalidate both properties and displayList, updateDisplayList() will get called first, then commitProperties() which will result in the grid not updating the rows. It appears the root of the problem is that the show event gets dispatched from within LayoutManagers validateDisplayList() loop, so invalidating a child object from within the show handler results in its updateDisplayList() getting called immediately.

Flex :: SOAP Variables In Network Monitor But Not Making It To Event Handler

Aug 13, 2009

I am querying a 3rd party web service and not all the data seems to be making it to the event handler. When I view the request/response in the Network Monitor I see a collection of data objects each containing two string variables (name, url) and two arrays (counts, breakdown). When the result handler receives the data and I view it in debug mode, the collection of data objects each only contains one string variable (name). What happened to the other string var (url) and both arrays (counts, breakdown)? what would cause this since it seems to becoming corrupt before it reaches the event handler but after it is received by the network? Is this most likely an IDE issue?

Actionscript 3 :: Flex's FileReference.save() Can Only Be Called In A User Event Handler

Jul 21, 2010

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.

Javascript :: How Does Set Event Handler Scope

Aug 7, 2011

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)?

ActionScript 2.0 :: Event Handler Not Working?

Jul 17, 2009

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.

ActionScript 3.0 :: Set Event Handler From Outside Flash?

Aug 8, 2009

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.

ActionScript 3.0 :: Return Value From Within Event Handler?

Nov 2, 2009

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.
