Flex :: Passing Data From Custom Class To Main Application?
Aug 4, 2011
Im a complete beginner in Flex programming. I have an application with a main .mxml file, and a certain class Foo that I call from the .mxml. In Foo, I make a URLRequest and listen for the Complete event. Then I found myself with the returned data in a Foo function, but I have no idea how to communicate it to the .mxml part of the application ! I looked into ArrayCollections but I can't seem to understand how they work. Isn't there a way to modify, from inside the class, a variable with a global scope ?

I know that the best way to make a connection from my main app to my modules is through interfaces.
So, my problem is, how can I implement an interface so my module can send and receive data from my main app?, cuz, I understand that my module implements an interface that is used by my main app.. but, can I do it "viceversa"?
Other issue I have is, why do I need to call my main app children if I can just import a module's class?.

I have a main mxml file (flex4) and want to pass a parameter (user_name) to a component in a directory called components. When I run the program, the user_name is NOT being sent from the main to the component file. (Interestingly, if you make the component visible, you can see the parameter has been passed).
I have hacked much larger files down to get the following two files:
Main
<?xml version="1.0" encoding="utf-8"?>
<s:Application
xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"

I have a custom class being constructed from my main class. In the custom class it has another custom class that is passed in as a parameter. I would like to strictly type the parameter variable but when I do, 'the type is not a compile type constant etc'.This, I understand, is because the custom class used as a parameter has not yet been constructed.It all works when I use the variable type ( * ) to type the parameter.I suspect this is a design flaw, in that I am using an incorrect design pattern.It is actually hand-me-down code, having received a large project from someone else who is not entirely familiar with oop concepts and design patterns.
I have considered using a dummy constructor for the parametered class in my main class but the passed in class also takes a custom class (itself with a parametered constructor). I am considering using ... (rest) so that the custom classes' parameters are optional.Is there any other way to control the order of construction of classes? Would the rest variables work?edit)in main.as within the constructor or another function
var parameter1:customclass2;
customclass1(parameter1);
in customclass1 constructor:

I'm trying to create a class which will create a tween for several different instances of an object. I am creating the instances in the Document Class. The trick is, I would like to specify how long each tween will take.
Here's what I have so far:
DOCUMENT CLASS
ActionScript Code:
package {
import flash.display.MovieClip;
import mcCloud;
[Code].....
As you can see, I have a variable "myTime" which syncs the timer and the tween. This causes to tween to repeat and the clouds to continually scroll across the stage. How can I determine the var myTime at the time I create each instance of the Movie Clip mcCloud?

So I'm trying to make a project with multiple rss feeds on one page. All the rss feeds are in one xml file. this works fine but now I need to retrieve rssdata from each rsslink.
To do that I want a variable to be filled up with the rssData that I retrieve via an external actionscript file.
So in my main actionscript I would have something like this:
ActionScript Code:
var rssLoader:RssLoader = new RssLoader;
var rssData = /* THIS IS WHERE I WANT MY RSS DATA TO COME */

I have a initApp.as which instantiates a class which needs to access the "currentState" property and the States array as well. However we cannot get this to work as we cannot see how we can access this information.
Within initApp.as currentState is accessed via "this.currentState". This does not work in the class which is instatiated within initApp.as. The following error is thrown:
"Access of undefined property currentState."

My main SWF file, "working_login.swf" has a movieclip that loads another SWF file, called "membership.swf". It loads this SWF file inside of a movie clip which, upon a press of a button, tweens the movie clip containing the "membership.swf" onto the screen. Membership.swf allows you to login using "testing" as the user, and "testing" as the password. I have no idea how to dynamically change the username_txt dynamic text on the main swf.
What I want:
I want it to display "Hello, guest!" when there is noone logged in and no cookie set. I want the program, upon someone logging in as "testing" to have the dynamic text box display "Hello, testing!" upon a successful login. Right now, I have absolutely no idea how to go about this. I am using a class to set the dynamic text, but I cannot figure out for the life of me how to set it up to recognize a guest VS someone logged in. These are the following files that I am using: [URL]

I have a document class called Main.as In the class constructor I have the following listener:
enter code here
var listeningFORModeChangeToStudent:Sprite = new Sprite;
listeningFORModeChangeToStudent.addEventListener(TellAllModeChangeToStudent.STUDENT,exp);
addChild(listeningFORModeChangeToStudent);
[code]....
In a third class I make a call to the despatcher in the previous class:
enter code here
var ThisTellAllModeChangeToStudent:TellAllModeChangeToStudent = new TellAllModeChangeToStudent;
ThisTellAllModeChangeToStudent.tellAllModeChangeToStudent();
I have trace statements in eveything and from this I know the despatcher in TellAllModeChangeToStudent is being called.The problem is that the listener in the main.as is not calling the function exp.I cant see why and I dont know how to check if the listener is actually seeing the dispatch event?

I have created a custom class. It seems to work (at least no errors), but when I create a button in the actual FLA that calls on the class, it doesn't change what I want it to change. Here is the class:

When I call for the class to make the button, it works. It also successfull calls the default.png from the class, but in the FLA the icon_retrofit.myIcon doesn't change the image to 'images/b.png'.

I created a movieclip with a star. Then, I creates a document class and I named it as Main.as.
In that document class I wrote:
package
{
import flash.display.*;
public class Main extends MovieClip
[Code]....
I´m not posting here all the code, but you can easily see that I´m using x_origin and y_origin variables to keep the original position of the movie clip. I will use them to move the star back to the original position.
The problem is that instead of being 20 and 30 respectively, tracing them I see that they are both ZERO. So when I drop the star, instead of going to x=20,y=30 it moves back to x=0 and y=0. I´ve to get the star position relative to stage, but I can´t find anyway!

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.

I had watched a CartoonSmart Tutorial on AS3, and the amount of code that goes into a button seems to much (especially coming from AS2). I tried to create a custom class to make my life easier for this, but... I ran into a snag.
Errors:
Code:
1046: Type was not found or was not a compile-time constant: MouseEvent.
I receive that error 4 times in these locations.
Code:
function ButtonClick(event:MouseEvent):void {
function ButtonRollOver(event:MouseEvent):void {
function ButtonRollOut(event:MouseEvent):void {
function ButtonDown(event:MouseEvent):void {
Here is my button_class.as file.
package {
public class button_class {
function button() {
}buttonVar.addEventListener(MouseEvent.MOUSE_UP , ButtonClick );
function ButtonClick(event:MouseEvent):void {

I have the following situation:I have an event handler, that displays small messages in my application's statusbar.These messages get passes through by dispatching events from custom components.A simple message could be like "HTTP Error" or so.Now, the main event listener, in the main application file, listens to the event dispatched by any custom component,but seems to refuse listening to events dispatched by custom AS classes.Here is my code for the custom event:
package main.events
{
import flash.events.Event;[code]..
So to sum it all up:
- The event listener listens to the custom event dispatched by any custom component.
- The event listener does not listen to the custom event duspatched by an AS class.
Those who wonder, the event really gets dispatched, that's why I added a trace call.
