Flex :: Make A Protected Property Public?
Dec 29, 2009
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.

Is it possible to have a property with a public getter and protected setter? I have the following code:
public class Mob extends Sprite {
// snip
private var _health:Number; // tried making this protected, didn't work
public function get health():Number { return _health; }
protected function set health(value:Number):void {
[Code]...
I did have this.health -= dmg; but I split it out to get more details on the compiler errors. I don't understand how the property would be considered read-only within the same class. I also don't understand how it's inaccessible. If I make the backing field, getter, and setter all protected, it compiles but it's not the result I want; I need health to be readable externally.

To my knowledge this doesn't break Liskov's Substitution Principle as an instance of a subclass can do all the things that an instance of a superclass can do.

If I have a .mxml file that has a method in it and a public property, can I have the method execute whenever the property changes.
<?xml version="1.0" encoding="utf-8"?>
<mx:HBox xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Script>
[Code].....
In another .mxml file I have added this .mxml file like so:
<viewComponents:MyViewComponent myProperty="{myVariable}" />

In my project I've defined a Point class to build Point objects. I also built a Polygon class with a (private) array property, Points. The polygon class contains a method getPoints() which return the current Points array. My objective is to built one or more Polygon objects and assign several Point objects to the Polygon's Points array. Let's say I've created two Polygon objects, plgPolygon01 and plgPolygon02. To both objects I insert three new Point objects into the Points array.
As I call the plgPolygon01.getPoints() method, i expect to get an array with three values. But when I do this, I get an array with six values. So I conclude: while I was inserting Point objects into the Points array of a Polygon object, this Points array seems to be public instead of private. Otherwise, I'd only get the Points I assigned to the first Polygon object and not all the Points assigned to polygons.

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..

I have declared some public static consts within a class Instrument. So that I can hopefully access them like Instrument.SAX, instrument.HARP, etc. etc. But when I go to trace out or compare the consts, it gives me this error:

I have planned to create an educational application / movie in Flash 8 (contains exercises and final tests etc.). I want to protect my application with username and password. The script inside movie should generate the password for given key say in my case username it will output the hex key which can be your password and no need to store it. cause you put same logic in your app which will generate the same hex key for same key i.e. is your username

I have Class1 with a read-only bindable property called age:
public class Class1 {
private var _age:int;
[Bindable(event="ageChanged"]
[Code]....
Of course the [Bindable] tag there doesn't make sense. But how can I achieve the same effect?
I believe I can dispatch some sort of ageChanged event from Class2 up to Class1 and then have an event handler in Class1 dispatch another local ageChanged event to which I bind Class2's age property.

I have the following inheritance structure:
var environment:AvEnvironment = new AvEnvironment(...);
addChild(environment);
environment.addChild(new Terrain());
environment.addChild(new Player());
I am trying to access a public property from AvEniroments class through the Player class, however I'm getting an undefined property error (#119). I've tried the following:
this.x = AvEnvironment.xs // public property in this class
this.x = parent.xs
I've also tried something like this:
var ev:AvEnvironment = AvEnvironment(parent);
this.x = ev.xs
but I get a TypeError. Error #1009: Cannot access a property or method of a null object reference.

Is it possible to add my own custom property to the flash.display.Bitmap using a public static method? I'm trying to write a bitmap utility that does something to a bitmap, and stores a Number property onto it afterwards.
[Code]....
I'm still learning AS3.0 OOP, I think that this can't be done with this method. I think I have to make a new Class that extends 'Bitmap', add the prop there, and then in the Main.as make a new instance of that class, point to the target Bitmap, and run the method in the extended 'Bitmap' class (?).

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

How do you make the childAllowsParent property of an SwfLoader go from false to true, that is, how as a parent application do you set up security to make the child app's events and other properties accessible to you. To read the flex docs on this, one would think nothing could be simpler:
"This property [childAllowsParent] is set to true if the child object has called the allowDomain() method to grant permission to the parent domain or if a URL policy is loaded at the child domain that grants permission to the parent domain. If child and parent are in the same domain, this property is set to true . [emphasis added]" So, I'm in a development environment and want to load an swf from my own system via an SWFLoader and then be able to monitor its events within the parent app.

I want to make a TextArea component public so it can be accessed from other frames. For example, I want to be able to say that if this button is pressed change the TextArea text to "1" and go to the frame.
I have no idea how to do this, i've tried : frameHome.textArea.text = "1"; to change the text but it doesn't work so i'm presumming that i'm a little off mark.

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 have been working on a Flex Mobile application using Flash Builder 4.6. I have 2 mxml 'views' in my project. In one mxml file, i have a function that grabs xml data. In my other mxml file, I have a refresh button that when depressed is suppsosed to call the function in the first mxml file in order to once again grab the xml data. I dont know how to call that function from outside the mxml file it is housed in. [UPDATE #2]* I thought I should share some more details about my issue.
It is a reddit client mobile app. It fetches the feeds, etc. In my main view called RedditReaderHomeView.mxml, I am using a splitViewNavigator spark component to house two other views like so:

I have a flex application which collects data entered by the user and posts it off to a web service I have running on a back end server. The flex application does not authenticate users (it's available for anyone to use without setting up an account) and communicates to the web service using HTTPS. There is an XML firewall in place for preventing certain malformed requests, DoS attacks etc and the web service validates all data received from the client.
If I was to sign the content then I could use the XML firewall to verify the signature but I assume that any certificate type data I embed in the client could be extracted out of the flex app through some means of de-compilation. My question is, is there any way of limiting calls to the web service to only those from my flex client? I understand that a user could input bad information but I'm really trying to prevent another client or 'bot'.
