I am trying to add evenListeners to movieClips that are created by a method in one of my Classes. Creating an instance of my class from the main timeline and then adding that instance to the stage.:
//MY CLASS
var createSlide:AddItems = new AddItems();
var scrollClip:Sprite = new Sprite();
addChild(scrollClip);
//ADDIMAGES CREATES 4 MOVIECLIPS
createSlide.addImages(BG,image1,image2,image3,image4);
//ADD TO STAGE
scrollClip.addChild(createSlide);
So how do I add event listeners to the movieClips created by createSlide?

I have a custom class which creates a new MC using a library MC. The library MC contains a dynamic textfield called productName.
The custom class object gets created fine and is displaying on the stage. It's also holding custom properties I set as well.
How do I control the dynamic textfield inside the MC, which is inside the custom class object?

package {

I've created a movie clip. Loaded an image and added it to the movie clip. Then added the movie clip to the stage:
var one:MovieClip = new MovieClip();
var firstTestImage:Loader = new Loader();
firstTestImage.load(new URLRequest("testImage1.png"));[code]............
Now I want the movie clip to have an eventlistener that will trace when clicked:
one.addEventListener(MouseEvent.MOUSE_DOWN, linkto);
function linkto(event:MouseEvent):void

I have class ShowCase that inherite from my class ContentMC (that inherite from MovieClip). In the class ShowCase I have an EventListner that calls a function in the parent class ContentMC. But I get an error that says "Access of undefined property restoreMenuItem".
This is my eventlistner in ShowCase.as.
showcaseItem.addEventListener("CONTENTMCCLOSED", restoreMenuItem);
Here I get the error, it doesn't find the function restoreMenuItem.
The function restoreMenuItem is in ContenMC and looks like this.
public function restoreMenuItem(evt:Event):void
{
}
How do I call this function that's in the parent?

Is it possible to have a textfield created in the Flash CS4 IDE that is associated with a sub-class of TextField? Or do I have to instantiate the TextField in code?

I want to add an event listener to a textfield that triggers when the user is "in" the textfield and hits enter. Think like you're at google and youre gonna search for something - you enter the keyword in the textfield and then hit enter, instead of clicking on the search button.

Im currently creating textfields in a for loop - though in this example only creating one TextField. My questions is, how do I remove the TextField child in another function? What im basically doing is, create a Textfield, addchild to a container - > then the container into another position - > then removechild and another text in the container. I've tried something like:

I'm trying to create a cutom made clickablle field using AS3 but I have problem registering an OnClickListener.What I do is create a subclass of MovieClip, draw a RoundRect on it and add a textfield as a child. Now when I click on that "thing", events are caught by the textField and I can't find a way to forward it to my MovieClip.
private function addListChild(i:Number, l:Number, c:Content):void {
var x:Number = 100;
var y:Number = 100;

I have created the MainMovieClip and Scrollbar as follow ....
my problem is that when I input japanese characters,the characters display at the top corner of the swf until I confirm the input. if I install FlashPlayer "flashplayer10_1_rc2_plugin_041910", then the japanese characters display in the textfield normally....why is that???
with flash player 10.0, I can't input the japanese characters in the textfield.
var mcMain:MovieClip = this.createEmptyMovieClip("mcMain", this.getNextHighestDepth());
scrp.contentPath = "scrollMovieClip";

I've created an button object in flash. The button contains 2 layers. One is the background image and on top of it is a textField. The textfield is dynamic. I use the button inside a movieclip and I export it in a SWC. The I'm trying to use it in flex.
I'm trying to do this:
var myComponent:MyComponent = new MyComponent();
myComponent.button01.theTextField.text = "Caption";
I get and instance of the button(myComponent.button01 is not null in Flex debugger), but the instance of the textField(myComponent.button01.theTextField) is null and I'm not able to change the text(but the default text appears onscreen). The code is compiled correctly in flex.
I exported the in swc the button control as well. So the button is not the default SimpleButton from Flash, but an derived class generated by flash(with the same name as the symbol defined in flash). It contains theTextField memeber, which is null.
Here is the button timeline(Layer 2 contains the textfield, and the textfield instance is named theTextField):

I'm just now learning the new object oriented way of scripting. It's been a wild ride, but I've finally learned how to keep script off my frames (very hard coming from as2).Here's my problem:
I have a TextField on the stage in my main .fla file named loadPercent.
I'm loading a jpg with preLoad.as and displaying the bytes loaded in loadPercent.
I can access my loadPercent TextField from my MainClass
but I can't access it from preLoad.as
the document class is MainClass.as
Code:
package
{
import flash.display.MovieClip;[code]....
I get three '#1120 access of undefined propery' errors for each time i try to access loadPercent.
a few basic questions: 1. all my files are in a folder in my documents, not in the flash directory, is this bad? I've seen people using com.whatever etc.
2. my main .fla file does not share the same name as my MainClass.as (it's not named MainClass.fla) Is that a problem?
I'm assuming these are inconsequential because my code seems to work up to a certain point.

What is the scope of a class created in Flash? If you create a class on the main timeline, can you use it anywhere in your project? If you use your class in a a movieclip, can you use that class outside of the movie clip?

I have some class that I created visually in Flash Professional CS5 by transferring drawn result into a MovieClip and extorting symbol into AS code. Now, I want to add some properties to the class. To be more specific, I've created Ball class and want to add to it variables that will represent vertical and horizontal speeds. How can I edit the class in order to do it? Also, when I wanted to add some visible external element to the class, at first I decided to add MovieClip property in the code itself, but then recalled method .addChild() that worked perfectly for me. Now, I can't do the same with non-visible properties. So, what is the difference between adding visible elements using .addChild() and adding them in the code itself?

I have an on enter frame listener defined in a function:
Code:
function sideClicked(e:MouseEvent):void {
removeEventListener(Event.ENTER_FRAME, loop);
var targetName=e.target.name;
var a:Array=[];[Code] .....
The looptoposition() function simple calls a function from a custom class repetitively to move an object until it reaches its position. This is the function it calls from the included custom class:
Code:
public function rotateToPos(a:Number,b:Number,c:Number):void {
if(!cubeReady){return;}
if(cube.rotationY<b){
cube.rotationY+=3;
[Code] .....
This gets the desired result visually - the cube rotates until the chosen point and then stops - however the listener continues. I have two problems:
1) I would like to remove the listener but can't seem to do so from the imported class - I'm having trouble referencing my functions in the root flash file.
2) I also need to declare that the function has completed - but the equalities mean that b is either greater or less than but never equal to? Whats a better way of getting the cube to rotate to a set position on each frame? The reason for the equalities are the cube can turn two different directions. So rotation could be negative.

I am new to AS 3 and I tried to solve this (probably really simple) problem, but I couldn't, so I gotta ask here. All I did was create a child through a function in my document class.It is in fact an altered version of the rotate circles tutorial from kirupa.
Code:
function makeCircle (e:Event):void {
var circle:BlueCircle=new BlueCircle ;

why my variable does not get updated when I try to modify it from an event listener function? for example in the code below _resultXmlList will be null if I try to get it from getXml I think there is no access to member variables from an event listener.
Here is the code:
Code:
package

import flash.events.Event;

Reading a book i stumbled on this example:
Here is the class:
package com.learningactionscript3.loading {
import flash.display.Loader;
import flash.display.LoaderInfo;
[Code]....
What I deduce from this example is that the swfLoader.contentLoaderInfo and _ldrInfo = this.contentLoaderInfo refer to the same object in the same memory location. So you may think: "well the last added event will overwrite the first one (the internally one added). But it doesn't. The two event listeners will respond sequentially. First the internal listener and then the external listener.

The following for loop dynamically creates 4 instances of the same button. Each button is then populated with its own textfield.I have given the textfield(s) an instance name of option0, option1,etc, etc. I want to populate the text in each field with something different (Home, Contact, etc, etc). I am trying to call the textField by its created instance name "option0", but I get an error saying it's not recognized.

I tried to search but 99% of the posts I saw were referring to manually created dynamic text boxes instead of.. algorythmically generated text for lack of better phrasing.
I'm trying to make an AS3 .swf that would display a small array of letters that have been created with TextField's, and not with dynamic text's being dragged onto the stage since there's going to be more than 100 of them. I've tried setting the textfield's .embedded to true, changing the fonts, making sure the text and backgrounds are different colors.. nothing.
In my .fla I have nothing for the document class under properties. In frame 1 there is one keyframe with three lines of code below and I've tried it with stop() and without. The class file is in the same folder and is MyArray.as This should be really easy but it's driving me insane.
MyArray.fla :
Code:
//stop();
import MyArray;
var test:MyArray = new MyArray();
