I have classes that need to communicate with each other, but are instantiated at different times.Therefore I feel I need to create a universal Event Handler that my classes can add event listeners to,and can receive dispatched events from.

In AS2 we can add additional event handler on same event as below code does.
on (rollOut, dragOut) {
// Statement 1
}
Now , I am workin in AS3 . So, how to add additional event handler on event in AS3
Let's say display Object's instance name is "myBtn"
Here I have include only Mouse Out only, Now I want to add additional event handler
myBtn.addEventListener(MouseEvent.MOUSE_OUT, myBtnEvent);
myBtnEvent(event:MouseEvent):void
{
// Statement 1
}
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 have the next code:

How do I remove the event handler onPress?

View 1 RepliesI 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)?
View 1 RepliesI'm loading some images from a database using a PHP script through CodeIgniter, but when I try to add an event handler to do some stuff with these images, Flex compiler is showing me an error:1180: Call to a possibly undefined method cloneCar.Why I can not add an event handler in this context?

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.
I have one event handler for several object's events. I would like to pass a value through to the function from the event listener:
ActionScript Code:
function chkEmpty(event:Event){
if(event.currentTarget.text==""){
[Code]....
So I am trying to essentially have one class dispatch an event into the flow when it is added to the stage, and have another class catch the event, but I'm having problems. I set up a little test to simplify/display the problem I'm having. There are 2 classes, and then just some init code on the timeline.
ActionScript Code:
//code for box 1
package {
[code].....
Is there a way to get the handler(s) function(s) of an event listener?
I'm trying to find a way to remove them without knowing what they are.
For example:
ActionScript Code:
if (mc.hasEventListener(MouseEvent.CLICK)){
// this object has a MouseEvent.CLICK listener
mc.removeEventListener(MouseEvent.CLICK, null );
}
Instead of null, I was hoping to find some function that retrieves the handler function.
Does anyone know if there is a way to get the name of the function that my code is running inside?
Code:
_btn.onPress = function () {
trace(something);
}
this would then output "onPress" or something like it...
I'm creating a button to play an movie clip using onClipEvent() but I couldn't get it works. It contains a button (text) and a cube (movie clip). On that movie clip I have a button.I want the animation of movie clip play while my mouse is rollOver on my text. Does anyone know how to make that works??[code]
View 1 RepliesIn a kiosk application (with NO mouse action) I try to mimic the action of buttons...with movie clips.I was wondering if that would be possible to create new event handler for MC?So that, by script, I could tell something like:
my_mc.selected = true
my_mc.focused = true
then have an event handler function like:
[code].....
And by the way, what's the main differences between addEventListeners and addListener?I have a FLVPlayback component from which i wanna play 4 different flv clips referenced in a xml file.The xml part works fine.So I have my 4 buttons (components) here. When i click the button 1, i want to either send the variable 1 to a function that is build to load the desired flv in the player. The variable would determine which of the flv to play.either that or when i click a button, i want to set directly the .contentPath of my flv player, load it and play it via a simple function that would be referenced to in the addEventListener call hope everything is clear enough.I'm having trouble just making the buttons send different variables to a particular function, according to which of my 4 buttons are pressed.button 1 sends 0button 2 sends 1button 3 sends 2button 4 sends 3that looks pretty simple but seems like i cant even do that by myself.
View 1 RepliesMy code of AS2 is given below. I do not know what event handler type is used and which event handler is used in AS3.
onEnterFrame = function(){
//
};
Typically when you set an event handler function for buttons by code, like:
mybutton.onPress = function(){
trace("Hello!");
}
[Code].....
is that event function accessible from code? how? I know there would be a property that you can access it by, maybe we can "decompile" an SWF to check out finally which property it stores the event code
mybutton.onPress(); // This does not work!
I have a number of flash files which contain the following deprecated code:
on (rollOver){ gotoAndPlay("over");}on (releaseOutside, rollOut){ gotoAndPlay("out");}
When loading the swf I get the error message, "The currently targeted Flash Player does not support the releaseOutside event." Then I have to use an earlier version of Flash Player and none of the hyperlinks work.
I believe you need to state the button name in AS2, but as I am not an AS programmer I am unsure exactly how to replace the code.
I'm building a flash piecve for aour FAQ section. I have an button instance controlling what show when a user mouses over a certain area. On click it displays the info box. What i need is a way when the user clicks, and then releases that the inlformation box stays, at least until another option is clicked.

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"));

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.

I have a game here, and I would like to add event handlers to my buttons to change the time. I know how to do all this, I'm just having troubling actually adding the event listeners to my buttons in my .as file.

View 1 RepliesOn my stage, I have three buttons all named instances ("Yogyakarta", Banda_Aceh", "Bengkulu"). I basically want to wrap the names of these buttons (and eventually several more) in a variable (nameBtn) and then addEventListener to the variable.
