ActionScript 3.0 :: Instantiate A Class From An XML Loaded Listbox
Nov 18, 2010
The following code works to instantiate a class from a listbox selection...
[Code]....
But when I try and load the same label and data from XML it does NOT work... Below is the for loop that I'm using to parse my XML and populate the listbox:
[Code]...
The setupID should be populating with a class that I can instantiate (just like when I hard-code it without using XML). Instead I get the error "Instantiation attempted on a non-constructor." I also received this error when I had quotes around the hard-coded version. So, I'm assuming that maybe the XML is being read as a string. But I haven't been able to find a way to cast it differently. I've been stuck on this for quite some time now.

I'm trying to use a listbox to instantiate a class. "SEA30_05_215_Single_Classroom" is a class that is loaded in using another function just fine. When I attempt to use the function below I get an error that says "Instantiation attempted on a non-constructor."Any ideas how to either fix the error or do it a different way? It seems like it should be a fairly simple thing to instantiate a class using a list box..[code]

No matter how much I try, nothing works.
1. Moving a loader instance to a movieclip containter returns a coercion error.
2. Moving the loaded image object to a MC container does not produce any errors, but remains as a bitmap object.
3. bitmapdata.draw() method seems to require either a bitmap or bitmapdata destination object.

I keep getting this error: Incorrect number of arguments. Expected 0.Probably just something stupid... but I'm struggling...I have two classes (ribostrand.as and nucleo.as) in a folder called architect. The main FLA file is outside the folder.I'm trying instantiate the nucleo class with parameters, from the ribostrand class... but its not working.
var ribo:nucleo = new nucleo("A",50,50)

I was chatting with my buddy about this, he is convinced you can do this and says he has done it, but I cannot get this to work.
I am wondering if it is even possible at all. I tried typing a var as a Class that is within the externally downloaded SWF and then making an instance but no can do.
some code
private static function onCompleteHandler(e:Event)
{
dashboardObject = e.target.content;
// registerClassAlias("Dashboard", ); doesnt work
[Code]....
So it seems you cannot make an instance of a class unless it is complied within the project SWF. Which if true is what I want it to do. I do not want people trying to make instances of my classes just from downloading the SWF file for what I am building here.

I have an abstract class which gives specific 'base' behavior to multiple sub classes. I want to instantiate a Singleton inside this abstract class. Is it good practice to:a) instantiate a class within an abstract classb) do this with a Singleton (I know these may be frowned upon)For clarity I will give an example, the method instantiating the Singleton is:
public function createErrorRepository(repositoryType:String):void {
this._errorFactory = ErrorFactory.getInstance();
this._errorRep = this._errorFactory.createErrorRepository(repositoryType);

To call a class we would type: var testClass = new TestClass();Can I store the class in an array, and somehow pull it when I want to call it the same way? I need to be able to call a new class like the example above, but from an array.

How can I instantiate another class object from a class instance? In the code below (which doesn't work) I'd like the function to return a new class instance based the passed argument's class. In other words, I want the function to return a new instance of MySprite without having to call new MySprite();.
var mySprite:Sprite = new MySprite();
var anotherSprite:Sprite = makeAnotherSprite(mySprite);
function makeAnotherSprite(instance:Sprite):Sprite {
return new getDefinitionByName(getQualifiedClassName(instance));
}

Possible Duplicate: Where is the "proper" place to initialize class variables in AS3
Whether its better to instantiate class on it's variable declaration or within a constructor? For example, this:
protected var _errorHandler:ErrorHandler = new ErrorHandler();
or this:
protected var _errorHandler:ErrorHandler;
public function someClass() {
_errorHandler = new ErrorHandler();
}

I've got a string which, in run-time, contains the name of a class that I want to instantiate. I read suggestions to use
flash.utils.getDefinitionByName():
var myClass:Class = getDefinitionByName("package.className") as Class;
var myInstance:* = new myClass();
However, that gives me the following error:
[Fault] exception, information=ReferenceError: Error #1065: Variable className is not defined.

Can someone point me in the right direction on how to instantiate any class at runtime with any given number of arguments?
As an example and to be more precise, I included an example below. How could I write this example in one line of code - ok, maybe two : )

I have some classes stored in a swc which I would like to instantiate using data pulled in by xml - using a string to reference the classname.So where I would normally use
ActionScript Code:
var tagline:Sprite = new Tagline1();
I would now like to do something like
ActionScript Code:
var tagname:String = "Tagline1"; // really the string comes from XML
var tagline:Sprite = new [tagname]();
I have a vague idea this is possible using square brackets, but I don't seem to be able to find out anything about it.

Using org.as3commons.reflect I can look-up the class name, and instantiate a class at runtime.I also have (non-working) code which invokes a method. However, I really want to set a property value. I'm not sure if properties are realized as methods internally in Flex.I have a Metadata class which stores 3 pieces of information: name, value, and type (all are strings).I want to be able to loop through an Array of Metadata objects and set the corresponding properties on the instantiated class.[code]I realize that I have to declare a dummy variable of the type I was to instantiate, or use the -inculde compiler directive. An unfortunate drawback of Flex.Also, right now there's code to account for typecasting the value to it's specified type.

example:
var c : Class = Sprite;
//This can be random class such as movieclip/etc
var o = getDefintionByName(getQualifiedClassName(c));
this works, but in flash develop, it says that the variable 'o' has no type declaration
which basically means
var o : SOMETHING = getDefintionByName(getQualifiedClassName(c));
but how do i put that something there when i do not know what its coming because of random classes?

I'm unsuccessfully attempting to instantiate a reference of a class that is passed as a parameter to another class. In this example there are 3 classes:
MainClass, Canvas, MyCircle
From the MainClass I am creating an instance of Canvas, which is passed a class reference of MyCircle as I want to create instances of MyCircle from within Canvas. However, the MyCircle constructor contains required parameters that are created from within Canvas. How can I pass and instantiate a class reference with required parameters?
MyCircle:
package {
//Imports
import flash.display.Shape;
//Class
public class MyCircle extends Shape {

I've got a document class (EgoGame.as) and another class (Ball.as) which has been duplicated to deal with several different video pieces. Inside the document class is a list of 'if' statements which decide which video should be played. At the moment I'm doing it the old fashioned way whereby if the condition is true....it tells the relevant Ball class to gotoAndPlay a certain frame within the linked movieclip...

I can't find a way to directly access a MC (or textfield, etc) on the timeline from a Class loaded into my Document Class. No problem from the Doc Class, but can't do it directly from the loaded Class. Is there a trick to essentiall extend the Doc Class AS from another external class?

I have two SWF files which I shall call container and slave. The slave file contains a movieclip that extends from a class I shall call base. base extends MovieClip and is compiled into an SWC. slave includes this SWC as a runtime library, while container includes it as merged (and does reference it so it should be compiled into the container SWF).
The container loads the slave like so:
bgURLRequest = new URLRequest(slaveUrl);
var context:LoaderContext = new LoaderContext(false, new ApplicationDomain( null ), SecurityDomain.currentDomain);
bgLoader.load(bgURLRequest, context);
When this loading happens, I get the error that class base was not found. I suspect this has something to do with the presence of the ApplicationDomain in there. I'm not sure what it does exactly, since I didn't write this loading code myself (but I do know that it's there for a reason so it can't be simply removed).

Migrating to AS3 is being harder than I supposed, because the way things are referenced. I have a stay movie clip instantiated from library like this:
Code:
var mcMyMain:MovieClip = new mcMain();
addChild(mcMyMain);
var mcMyChild:MovieClip = new mcChild();
mcMyMain.addChild(mcMyChild);
Within mcMyChild I have a timeline with some animation, and, at the end of this timeline I want to instantiate another movieclip in mcMyMain (that is in stage) like this:
Code:
stop();
var mcMyTest:MovieClip = new mcTest();
stage.mcMyMain.addChild(mcMyTest);

I would like to know if its possible, to use a string in order to create a UI element.I think many people have this kind of problem, they want an easy setup in flash to generate a dynamic UI, through code.It should look like this (pseudo code):
addToStage("Button","add");
addToStage("TextInput","name");
private function addToStage ( o : Object, str : String ) : void {

I've been going crazy trying to figure out a couple things, spent the last few days scouring the forums and my understanding of actionscript and php aren't advanced enough to understand what I need to do.I have a very basic contact form (one I've successfully used before) that I thought I would adapt for a new project (to include a couple listboxes).In Flash, visitors enter name and contact info, then we want a listbox for them to select an event on a specific day, then another one that they select a time (both listboxes will be populated within flash, so no dynamic loading).
They hit Submit and the form information is sent to our email address using php.The first difficulty I had was how to capture the selection of the listbox. I don't know much about actionscript, but I thought that would be pretty straight forward and was hoping I'd find something in the community to keep it simple for people like me.
Then to send it to the php email document, I'm not sure how to treat it the standard text is easy to prep for php but I'm at a loss on the listbox-selected items.Right now I try to fill out the form, I hit submit, and get a message: undefined.I commented out the second listbox so I could just focus on getting one to work, but I'm not sure which stage I'm doing it wrong.[code]I think the php is good, and pretty sure I just don't know what I'm doing with the listbox selection.
