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.
ActionScript Code:
package code
{

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.

Code:
package

import flash.display.MovieClip;

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.

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.

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{
[code]....
And then this in the AS:
newPanel.getTitleBar().addEventListener(MouseEvent.ROLL_OVER,over);
Still getting the same error.

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 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?

When I want to see:
pub: true

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.
