ActionScript 3.0 :: Flex Protected Functions And Vars?
Oct 11, 2009
since i started using Flash Builder (Flex 4) i could see that it can auto-generate some handlers for example if i have a <s:Button> and i add a click="" i get a hint of "Generate Click Handler" and when i click Enter he writes this code:
Code:
protected function button1_clickHandler(event:MouseEvent):void
{
// TODO Auto-generated method stub
}
Now i knew about public and private things(functions/vars) and if a function was public i could execute it form outside of the class and inside. But if it was private i could only execute it from inside of the class and i couldn't execute it from outside of the class.
So anyway, what does "protected" mean? what does it do?I was thinking that if i load a SWF in my app I can go inside of that SWF and execute functions, read values from variables, or anything like that ... and that seems like a security problem ... So i was wondering if the "protected" keyword could help me with this security problem. And if not, I would like to know what is it good for
why (in this example) the use of a protected functions is required. It is an Adobe example showing an audio mixer board.I included just the code of the main document.
I have this function in the parent class: ActionScript Code: private m_colors:Array; protected function set colors(clrs:Array):void { m_colors = clrs; }
Then, in my child class I want to call this as: super.colors = [15, 255]; But it throws an error, it says: Ambiguous reference to colors. If I do the same with a common function, not a setter one, then just calling it with its name in my child class works fine.
how can i call public functions or vars of a sprite class from another class (or frame script)? i keep getting 1061: Call to a possibly undefined method getSide through a reference with static type flash.display:Sprite.
//Framescript var a:Sprite = new customRect(); addChild(a);
Lately I changed Flash CS3 for CS4. In older version classes written by me worked fine. However, in CS4 I have serious problem with them. Compiler states that part of my functions and vars are undefined, which is not true. I tried everything - changing name of class, functions, moving class file to different directory, removing package. I even counted { to check if they have pairs. I'm really out of options what can cause those errors.
Here are error given by compiler:
1120: Access of undefined property mnChangeMan. 1120: Access of undefined property ChangeManSliders. 1120: Access of undefined property ChangeManInput.
i am builiding a photogallery where at each stage i load six thumbnails. Each "placeholder" is initially set to 20% xscale and yscale and when each thumb has fully loaded, i want to have the thumb tween from 20% to 80%. The jpg thumbs are loaded inside the placeholder.when the thumb has fully loaded, goodToGo = 110 and so i want to trigger the AS tween.[code]to get some idea of how it would look, check out URL...and click inside any of the collections.
Could anyone suggest how to fix the function at the bottom so that when button forward_btn with label "Go to next Training Point" when clicked recalculates the fields created in function fileLoaded.[code]

I'm trying to extend a class like panel so that I can fire click events only when the title area is clicked on. The title area is a protected uicomponent of Panel called titleBar. So I want to make that component public.It seems like I'm almost there but I'm getting a "TypeError: Error #1009: Cannot access a property or method of a null object reference." when it tries to add an event listener to the titlebar.
here is my extended panel
package custClass{ import mx.containers.Panel; import mx.core.UIComponent; public class ExtPanel extends Panel{
I've seen some discussion on how to load a child swf using swfLoader and accessing it's variables but I am wondering if it is possible to do this without adding any code to the child swf.Either accessing public vars or listening for funciton calls would work fine
In my custom button component, I want to get a handle on the textField (The internal UITextField object that renders the label) in the Button so I can modify some properties on it. It exists as a protected var in Button.as How can I do that in my mxml component?
i think i might be missing some information here about how to manage classes and display objects. In the main .fla i have a mc called player; so I made a player.as class and put a linkage on player mc considering it would work as the mcs class. Well, its not working, the mclip is not noticing any of the vars and functions i added in the class. Anyone figures whats going on? How to make it work?
I installed Eclipse with Flex plugin. And I found in my current workspace, IntelliSense can only show the public methods, it cannot show me the protected methods (but it can compile and the app runs well).However, in other workspaces, it works well.If I create a new workspace, it's the same, that the IntelliSense can only show me the public methods, not protected methods.
i'm trying to figure out how i can handle login protected actions in RoR (Ruby on Rails) with Flex without using weborm or rubyamf remoteobject.I'm in the situation where i have to fill a datagrid with results of an HTTPService request after i log in correctly into my application. Can anyone suggest me the way to accomplish that?
I am developing an air application where I have to drop an image and save the Image path, width, height to variables and pass those variables to external swf. I load the swf like this:
var myLoader:SWFLoader = new SWFLoader(); var url:URLRequest = new URLRequest("myExternalMovie.swf"); myLoader.load(url);
I am getting this error: the way I am passing the URL of the swf is incorrect and not supported in AIR.
I have a component called a TableDataViewer that contains the following pieces of data and their associated set functions:[code]This component is nested in another component as follows:[code]Looking at the trace in the logs, the call to set table is coming before the call to set dataSetLoader. Which is a real shame because set table() needs dataSetLoader to already be set in order to call its load() function.So my question is, is there a way to enforce an order on the calls to the set functions when declaring a component?
that is there any way to protect the Flash source (FLA) file with password. So that if any body wants to open the file in flash it should ask the password before opening.
I have a protected swf file we need to open for work but the one who protected it is no longer around. What is the best program to open this protected swf?
Is it possible to make my CD copy protected?? So that nobody can create duplicates from it.
My CD contains the main installer that copy all my .swf and main .exe projector file to the hard disk of my client's computer. I am going to create 1000 copies of this project. But I just want to be safe that nobody can duplicate my CD. Is it possible in actionscript 2.0 or any other tool that works for me..
so I have a Track system with some kind of protection. So to get some data from any URL you have to pass protection like this [URL] and then (in browser) you can see some pages [URL] (if you havent passed login youll get no content)so how to login and get data from page using flash/actionscript (btw I am triing to create an rss reader)?
as many of us is aware is possible to dowload youtube videos using AnyVideo converter or any similar software. The basic mechanism is that, when bufering a video, a set of images is sent to the client machine, that's because youtube videos are in flash format. Not sure which format, .f4v, 4fp . I assume is .f4v rather than .4fp as the video can be dowloaded.
Parts of me would argue that is impossible to make a totally protected video. Every time you see a video the stream is dowloaded in the local machine and thus with a software reading the steram and converting it to mp4 or either other format it should be possible to copy the video.
i have the url of a password protected xml, and i need to load it in my application. but i can't figure it out how. i did find an example but it was in actionScirpt 2 and i'm having troubles coding it in 3.0.
ActionScript Code: var _login:LoadVars = new LoadVars(); var loggedInXML = new XML(); loggedInXML.ignoreWhite = true;
