ActionScript 3.0 :: Event In Class / How To Identify In Another Class

Jul 14, 2009

I have a class (called Units) that defines sprites which react to mouse events (being dragged around).My main .as class (called Loader) imports the Units class, sets up several shapes from Units as objects into an array (my_array[i] = new Units(j,k,l);) and then calls addChild in a loop to add them to the display list (addChild(my_array[i].shape);).All fine and dandy, but if I want a shape to go to the top of the display list when dragged about, how do I do it? The problem is that the mouseEvent is in the Units.as class, but the addChild is in the Loader.as class.The only thing I can think of is to strip the mouseEvent out of Units.as and add it to Loader.as - but that would mean adding an event to every shape in a loop, which seems inefficient.

Flex :: Difference Between Class Reference And Class Instance?

Jun 28, 2010

Given that both of these calls to getQualifiedClassName return the same thing (mx:Label), how would one go about programatically differentiating between an instance of a class and a reference to the class...

var lab1:Label=new Label();
var lab2:Class=Label;
var qcn1:String=getQualifiedClassName(lab1);
var qcn2:String=getQualifiedClassName(lab2);

In other words, how could I know that lab1 is of type Label, while lab2 is type "Class". typeof() simply returns "object" for both... getQualifiedClassName returns "mx.controls::Label" for both...

Flex :: Reference WindowedApplication From Inside A Class?

Nov 12, 2011

I'm using Flex 4.5, and I have imported a custom class I wrote into the main MXML file.

Inside the class file, I want to be able to create a TitleWindow using the PopUpManager like this:

package classes {
import components.*; // My custom components
import mx.managers.PopUpManager;

[Code]....

This is because this isn't pointing at WindowedApplication. How do I make the first parameter in .createPopUp() point to the WindowedApplication?

Flash :: Creating An Instance Of A Class That Implements An Interface Based On The Class Name?

Feb 17, 2011

Is there a way to generate an instance of a class that implements an interface based on the name of the class?

I am trying:

var ClassReference:Object = getDefinitionByName("movement.OuterSpaceMovement") as IMovement;
var m:IMovement = new ClassReference as IMovement;
trace("startup..." + m);

-But I am getting an error message ReferenceError: Error #1065 (OuterSpaceMovement) not defined.

I have several classes that implement the same interface (IMovement) but I need to be able to generate new instances of these classes and then pass these instances as a datatype (IMovement datatype) to other classes...

So then I tried:

var ClassReference:Class = getDefinitionByName("OuterSpaceMovement") as Class;
var m:IMovement = new ClassReference() as IMovement;
and this doesn't seem to work...but the following
var m:IMovement = new OuterSpaceMovement();

Actionscript 3 :: Flash Failing With A RSL Library, When Main Class Extends A Class And Implements An Interface?

Mar 13, 2011

I'm trying to load a RSL library into a flash animation developed with Flash CS5 IDE, that extends a custom class and implements an interface. I have reduced the problem to the simplest setup and find that I can have my main class extend another class or implement an interface, but not do both at the same time if I want to load an RSL.I have a very simple class to extend:

import flash.display.Sprite;
public class MySprite extends Sprite
{[ code]...........

but if I want both I get the VerifyError: Error #1014 with MySprite not found and ReferenceError: Error #1065.

Flex :: Identify The Original Message That Triggers MessageFaultEvent?

I'm using BlazeDS to send messages in Flex. Inside the UI component, I defined a producer like the one below:

I was wondering inside faultHandler how I'm able to identify what message causes the error. As it seems there's no way to get the reference to the original message.This is the code snippet how the message is constructed and sent.

private function sendMessage():void {
var message:AsyncMessage = new AsyncMessage();

Class Or Interface Could Not Be Loaded?

Apr 20, 2009

I'm trying to publish a swf with Flash CS3.

I have one .fla file and two .as files. I think my problem is I don't know how to set the path for the action scripts. All three files are in the same directory

The files:
dtd.fla
TransformItem.as
TransformManager.as

The error: The class or interface 'gs.TransformManager' could not be loaded.

dtd.fla code appears to have an appropriate import: import gs.TransformManager; var manager_obj = new TransformManager([], onTransformEvent, true, false, false, false, false, true, true);

TransformManager.as code appears to have an appropriate import: import gs.TransformItem;

ActionScript 1/2 :: Class Or Interface Could Not Be Loaded

I'm doing a simple link code. I've tried many diferrent ways to do this but this error keeps comming up saying The class or interface could not be loaded...

home_btn.addEventListener(MouseEvent.CLICK, gotoURL);
function gotoURL(event:MouseEvent):Void{
navigateToURL(new URLRequest("my site"));}

This is the most recent method I've tried in doing this. I've tried changing the publishing settings of the document to and from Action Script 3.0- using an import command. But thats too complicated.

C# :: - Does A Class Have To Implement A Interface Directly

Dec 30, 2009

Quick question. Does a class have to implement a interface directly to be accepted, or can it be a child of a parent class that implements it. so If I pass a child object into a method that only accepts IOBJECT, but the child class parent implements IOBJECT. will child object be accepted ?

Actionscript 3 :: Class Implementation With Interface?

Sep 11, 2011

I have created the following classes for sharing images. They implement an interface, but I need a way of switching between them with user interaction. I've done it the following way:As you can see, service 1 and service 2 implement iSharingServices, and inherit from PolimorphSharing.PolimorphSharing is simply and an abstract class that implements the methods I want public from Service 1 and Service 2. Those methods will then be overridden on the Service 1 and Service 2. Because I need a way to switch the service in runtime, I've created a gateway class that inherits from PolimorphSharing. I can then call it the following way:

private var sharingService:PolimorphSharing = new SharingServicesGW('svc1').createService();

This all works flawlessly, and I can now switch between services with no problem whatsoever. However, I feel there's something wrong about it, so I would like to ask you guys for some advice on how to better implement this.

UPDATE:
Just adding some more insight to this. Basically the idea here is for my client to be able to upload images with various different public sharing services such as imageshack, imgur etc. I want my client to be able to select the service in which the image is to be published to (hence the "switching between them with user interaction" bit of the question.

The method that does the uploading bit, is requestShareImage(), processResults() simply turns whatever gets returned to a unique format, so my client can read off it always the same way. getObject() is my accessor, and onIOError will handle exceptions with any of the public API's

I am getting an error with RegExp class at my flash document. I am using an Action Script 2.0 at my document. Is RegExp class is not supported in AS1/AS2 ?

My code is as follows
function validateEmailAddress(emailString:String):Boolean {
var myRegEx:RegExp = /(w|[_.-])+@((w|-)+.)+w{2,4}+/;
var myResult:Object = myRegEx.exec(emailString);

ActionScript 3.0 :: Purpose Of Having Abstract / Interface Class?

Feb 2, 2009

whats the purpose of having to have an extra class such as abstract class in Flash where the methods has no implementation,but the subclasses declare those implementations.The advantage of having the methods declared in subclass than the superclass is that it would not affect the other subclasses when there are certain changes.That makes me wonder, isn't it better not to extend(inherit) empty methods but directly create a class as its own? unless there is something that the child could use from parent.Anyone could give me examples of how applicable using abstract classes/interfaces?

Actionscript 3 :: Flash CS5 Reference A Display Object From A Class Other Than The Document Class

Jul 28, 2011

Using Flash CS5 Professional I have created a symbol, dragged it onto the stage, and given it an instance name of GreenLight1. If I want to make this visible from the document class, I can simply do the GreenLight1.visible=true; and poof it's good to go when I test the file. As long as I stay in the document class I am good to go, but now I'm trying to move to another class and hitting ALL kinds of trouble just trying to get Flash to allow me to access this simple object. All I am looking to do is have this GreenLight1 go invisible (visible=false) when a certain condition occurs in this new class and Flash just won't let me access GreenLight1 at all. Things I've tried thus far:

stage is passed to the class and is referenced by _stage and is working just fine when I do _stage.addchild or anything like that. So I have tried "_stage.GreenLight1.visible=false;" and I get "ReferenceError: Error #1069: Property GreenLight1 not found on flash.display.Stage and there is no default value." My document class extends Sprite, so I figured I'd try the root function. So I tried "Sprite(root).GreenLight1.visible=false;" and I get "1119: Access of possibly undefined property GreenLight1 through a reference with static type flash.display:Sprite." I tried to create the Resource class as described therein. To which I came across the same problem that I started with in that it doesn't know what GreenLight1 is to begin with so I got "1120: Access of undefined property GreenLight1." Here is my code for Resource.as (am I supposed to pass something to this class from the document class?)
