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?
tell me why this doesn't work?

Say I have an array with 4 string elements that are 4 different urls. On the stage I have 4 movieclips that I want to have listen for a CLICK event. When the user clicks a button, the navigate to one of the 4 urls.I can loop through the buttons and add and event listener to each:
Code:
private function applyPlankLinks():void {
for (var i:uint = 0; i<numberOfPlankBtns; i++) {

I have a 16x16 grid of buttons, and want to add an event listener to each of them so when clicked it will return its unique grid position number (anything between 0-255);
What I have so far:
public static const GRID_SIZE:Number = 16;
private var i:int;
private var j:int;
// Constructor
public function Grid()
[Code] .....
Unfortunately every time the listener function is called by each button, it uses the last two values of i and j, which in this case return 255 for every button.
I'd like to know what's the different using global functions and functions with param..Why using params? When the as3 developer uses it?
View 3 RepliesI have 2 functions. Each one is being called by a different event listener. Both event listeners work because I am able to trace strings in both of them.. my problem is that i am trying to create a variable that is local to both functions. The first function "working" adds a number to the variable and when the second event listener triggers function "notworking" which retrieves this same variable called "counting" both functions are called automatically by event listeners.. how do I do this? i am stomped!

View 4 Replies I have a movie clip that contains several movie clips, only one of which should be shown at a time. Which one is shown, depends on what buttons the user selects.Having trouble with the syntax for passing the argument in a button to the function that controls the tweening of the clips. (When I hard code the references into the function, it works, so I know the basic function is ok).There's a clip called 'slide1_mc' which contains various MC's to be shown based on user selection (in this case, using 'system' clip as the first one already showing). Here's the code in the parent clip of that item:
Code:
var currSection = slide1_mc.system_mc;
function changeSection(newSection):Void {
TweenLite.to(currSection,.3,{_yscale:200, _xscale:200, _alpha:0});
[code]....
Here's one of serveral buttons that will control the content to be seen:
The code in the button is:
Code:
var changer = slide1_mc.software_mc;
smallButton.onPress = function() {
_parent.changeSection(changer);
};
So - the initial part of my function works so I know my 'external' initializing of "currSection" is working (that clip is zooming/fading out)... but then the clip that I want to fade in isn't doing anything.
i have been playing with the Zend Tutorial - and all works fine... however, stuck on something that i found quite easy in amfphp/as1&2

i have a music jukebox, with ten buttons. in the first keyframe, of the main timeline, a put a function that will be used for every button to load the mp3 to play. The problem, is that when i pass the arguments on each button to call the function, the "filme" and "som" arguments are lost.
here is the function:
function carregaSom(filme, som, url, msg1, msg2, tempoComeco){
_root.createEmptyMovieClip(filme, 1)

Is it possible to pass arguments "by reference" instead of "by value". I know it's possible in almost every programming/scripting language I came across until today, but I didn't find any hint for doing it in Actionscript For those who don't know what "by reference" means: If you want to pass a Number to a function, say
Code:
var mynumber:Number = 5;
calculate(mynumber);
and you change the value of the argument inside the function, e.g.
[code]....
then the call to calculate normally does NOT change the value of mynumber because you have passed mynumber "by value", which means the value of mynumber has been copied to the num argument. This means mynumber is 5 all the time.Now sometimes u want to be changing arguments given to a function inside the function, and this is where u will normally use references. Passing mynumber "by reference" would mean that after calling calculate the value of mynumber will be 6...I know complex Objects like MovieClips are passed by reference. But how to do it with simple DataTypes like Number, Boolean etc.?
In my database i have a field called "live", and i only want to grab entries in a table that have "live" set to "1"
This is what i have tried, but it doesn't work....

PHP Code:

{
$result = mysql_query("SELECT * FROM testTable WHERE live = '%s';", $live);
[Code]....
You can do this:
PHP Code:
public function (args ...)
To take in any number of arguments. Is it possible to then give the content of that args array to a new function:
PHP Code:
public function bla (args ...){
pleh( changeArrayIntoArgs(args) );
}
So that that would be the same as just passing arguments manually. lets say bla got 3 arguments:
PHP Code:
bla(v,vv,vvv);
So that bla then executes:
PHP Code:
pleh(v,vv,vvv);
I've drawn a pretty button in Flash and given it the Class name PausePlayButton. It extends PlayerController, which allows it to toggle on and off and control whether a MovieClip is playing or not.When I instantiate it, I want to pass a reference to the MovieClip it controls into the contructor so that PlayerController has access to the MovieClip's public methods. However, I can't pass a reference into the constructor of PlayerController, unless I can pass it into the constructor of the symbol itself and call super. But where is that constructor? How do I give the button a reference to another object?

I'm having trouble with the constructor for a custom Class tied to a library MovieClip.
Say I have a MovieClip in my library named Circle, which is tied to the class com.shapes.Circle . I want the Circle class contstructor to take 2 arguments, xScale and yScale:
public function Circle(xScale:Number, yScale:Number) { }
However, if I try to call that from in code, for example Circle ball = new Circle(3.14,2.0); , I always get an "Incorrect number of arguments. Expected 0" error.
Is it possible to have a custom class tied to a MovieClip that can take arguments, or does Flash not allow this? I'd asked about this before and thought I figured it out, but from looking at it now I apparently hadn't figured it out and had resorted to a sloppy workaround; I'm hoping to fix it now.
Is there any way to pass an argument to a function being called by a ContextMenuItem?The effect I want would be what one might expect from this pseudocode:
Code:
var cm = new ContextMenuItem("Start Alt", set_row_style('start_alt_here'), separatorBefore=true, enabled=true, visible=true);
Which obviously doesn't work, or I wouldn't be asking.So far I've tried using the captions as a basis for a switch condition, which works.
Code:
function set_row_style(obj, cm) {
switch (cm.caption) {
case 'start_alt_here' :
...
But I'd rather not use an arbitrary string as part of a function.The only other option I see is using a listener for each ContextMenuItem, then calling the function with its arguments from there.Is there any more direct a way to pass an argument to a function from a ContextMenuItem?
I want to have an array, where each value is a function, where each function also has a set of arguments.
What is the correct syntax for setting a value of an array as a function?
Lastly, how do I pass arguments into the array's value?

var funcA = new Function(a:Number, b:Number){return a + b};
var funcB = new Function(a:Number, b:Number){return a - b};
var funcC = new Function(a:Number, b:Number){return a * b};

The problem is I get Error: Error #2094: Event dispatch recursion overflow. Why does removechild keep getting called if this.parent does not exist? Why doesn't removing event listeners work?
Can event listeners only be added to the class which dispatched the event? I ask because I want to have the logic for the listener on the main class, and the action is dispatched on click from a thumb which is instantiated in a scroller class. Kinda like this:
ActionScript Code:
pseudo code:
class main {
main() {
[code]....
This doesn't work. Why can't the main class listen for an event on the thumb class?
An odd thing is happening for me, my eventlisteners only fire off once then they seem to stop working.
This thing is a movieclip that slides up the parent movieclip and another movieclip within mc slides it down. They only work once.
ActionScript Code:
slider.up.addEventListener(MouseEvent.MOUSE_UP, activateSlider);
slider.down.addEventListener(MouseEvent.MOUSE_DOWN, activateSlider2);
var frameBoolean:Boolean = false;
[Code].....
hboxvar.addEventListener("mouseDown",dosomething(3 43));
hboxvar.addEventListener("mouseDown",dosomething(1 23));
hboxvar.addEventListener("mouseDown",dosomething(1 2342));
public function dosomething( somenumber:Number ):void {
//do something here
}
I try to do above function but I need to pass variable from hboxvar but not from inside function suggested by macromedia.
any one frustated with this way of passing multiple parameter which depends on what to pass in flex 2 using addEventListener ?

Passing additional parameters to function listeners You can pass additional parameters to function listeners depending on how you add the listeners. If you add a listener with the addEventListener() method, you cannot pass any additional parameters to the listener function, and that listener function can only declare a single argument, the Event object (or one of its subclasses).
I'm working on a website navigation wherein I want that on clicking the navigation buttons, a movie clip eases out to that clicked button to show the current page. I'm able to move the movieclip to the button's location but I need to remove the event listener once the movieclip stops over the navigation button.
