magine a Flex application which contains spam/eggs.as: package spam {public var eggs:Eggs = new Eggs();

How would you go about calling the public properties and methods of a SWF you load in actionscript?
I have been using stackoverflow for years to answer my programming questions so I wanted to give back by writing a guide to an issue I had a lot of trouble figuring out. This is my first user guide so tell me if there is anything I can do to improve it.
When load and SWF into another, the loader SWF can get definitions in the loaded SWF using ApplicationDomain.getDefinition(name:String) in example:
package
{
// ... imports
public class SWFLoader extends Sprite
[code]....
how can I get ALL the definitions and not just ONE of them?
I use Loader.unloadAndStop() function on loader which was used to load an SWF, but I can still reach classes using getDefinitionByName. How to remove them from the memory?
View 1 Replieswould like to know if there's a way to overwrite a specific definition in the "currentDomain" with one available in a child swf?
I'm loading swfs as assets, and since some of them have code in timeline (mostly stop()'s) i'm exporting symbols as subclasses of my .as
however would like if theres a way to be able to simply write:
var myBall:Ball = new Ball();
instead of:
myBall:Ball = new ballSwfAppDomain.getDefinition("sandbox.Ball")
I'm literally new in AS3 and slowly trying to migrate in thats why im here seeking for help. Can someone help me how to access/control a certain public variable in a loaded swf from the main swf? this problem has been paralyzing me for days. (sigh...) [code]...
View 1 RepliesI'm attempting to compile a Flex application from an ANT script, inside of Eclipse (CFBuilder, based on Eclipse), and I've run into this error:
Could not load definitions from resource flexTasks.tasks. It could not be found.
I haven't been able to find anything that gives directions on where this file (flexTasks.tasks) should be copied to, if it's needed at all. Some places indicate that it should be part of the flexTasks.jar file. I've tried two different things:
Copy the jar file into the ant/plugins/lib folder (and restart my CF Builder instance)Specify the path to the jar in the classpath attribute, as suggested by the comment on this page Neither helps me get past this error.Here's my build script, for reference:
<project name="Tagging" default="compile-tagging" basedir=".">
<!-- setup flex compilation capability -->
<taskdef resource="flexTasks.tasks" />
<property name="flex.src" value="./src" />

I have two SWFs: main.swf and external.swf. main.swf needs to access some methods in external.swf, so it loads external.swf into itself and uses getDefinitionByName("package.Class") to access the class and one of its methods:
var ExternalClass = getDefinitionByName("package.Class") as Class;
var ClassInstance = new ExternalClass();
var NeededFunction:Function = ClassInstance["NeededFunction"] as Function;
var response:String = NeededFunction(param);
Now, I need to extend the functionality of NeededFunction (which is a public method)... I know it's possible to override public methods, but how would I go about this with a dynamically loaded class?
I was thinking I could do something like this, but it doesn't work:
var ClassInstance["NeededFunction"] = function(param1:uint):String {
var newString = "Your number is: "+param1.toString(); //New functionality
return newString;
}
I am trying to set a variable in a titlewindow pupup and use it in a script section. The variable is not being set and I don't know why. Here is my Main.mxml file:
[Code]...
I have a class like this..
public class Doc {
public function Doc():void {}
public var myVar:Boolean;
}
How can I know if the value held by myVar is default false, or someone has assigned false to it? Isn't there an undefined state? How can I achieve such a thing?
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.
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.

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'.
I have a datagrid with itemRenderer in datagridcolumn as my custom component(c1). I am getting the dataprovider data in custom component by overriding the set data function, it is fine. But now my custom component(c1) is also having another custom component(c2).
Now the doubt is - how to get the dataprovider data in c2 component?
i want to know what i should put befor .mx_internal

I work with Flash CS4 and lately I've been looking for certain classes to ease my work. To be more precise Atom/RSS2.0 parsing classes. But the best result I found needed me to work with FLEX. Now I can't get this to work with flash CS4. There's no apparent way to make this work. I can build my own parser or look for one that doesn't need Flex. But it looks like the future is more FLEX oriented.
EDIT : I know how Flex Code and SWC files should work. But every time I try to use them I get some bizarre error about missing classes and methods that are part of FLEX but not included in Flash...
My flex project uses FA-Bridge, and apparently in Safari browser I cannot call any of my public AS functions that have arguments passed in. For example I can call this AS function from javascript:
[Code]....
In the above call safari throws an error # 1063, (i.e. Argument count mismatch) in the safari javascript console, and points to line 561 in FaBridge.js. It thinks I didn't pass in the requied parameters. Now the above issue exists only on Safari. Both of the above approaches work on IE, Firefox and Chrome browsers. Note: I am NOT using swfObject for embedding my swf.
Which is a much better practice in binding a value in Flex?

View 1 RepliesThis appeared as I was trying to use a mouseEvent to move an object.I placed the variables for mouseX and mouseY in the public class. I did the same for direction X and Y but there was no error message for those.
View 1 Repliesi need to create an arbitrary number of display objects using a for loop because the number of objects will depend on the number of items in an xml file.
so i want to control the objects using actionscript. in as 2 i could create a temp variable in the for loop and use attachMovie() and assign an instance name. i know in as 3 you can use the .name property, but i heard you had to use the variable handler to control the object.
so i can't do this because it generates an error:
var numOfItems:uint = 5;
for(var i:uint = 0; i < numOfItems; i++)
{
var mc[i]:MovieClip = new MovieClip();
}
Is there a way to get a list of the exposed functions from a Flash object? For example, you could get a list of all methods in an object by executing[code]...
The only issue is that this won't expose any methods registered through the ExternalInterfaces API. I can try and see if the function exists (object['method']) and it tells me it is a function, but I would have to guess every existing method in this manner..
I'm accessing the classes from an externally loaded SWF so that I can "skin" SWF applications at runtime. Everything works fine but I'd like to make it as dynamic as possible and allow developers to access all the class definitions in a loaded SWF without having the FLA file or a list of their names.

This seems like it would be really easy but for some reason it's not working.
I have a class file, class DataSet, which right now only takes an XML file, parses it, and pushes the XML into an array:
The object is instantiated and an XML file is passed back to the object definition. If the XML file is successfully loaded, the class should then called the function parseXML() and put the data into the array.
But for some reason, parseXML() is never called. I have no idea why this isn't working, because the syntax checks out and I've seen millions of other files where functions call other functions.
Here's the class file:

I wrote two projects using the same 3D library but I modified it pretty heavily in one (to the extent that the inheritance is pretty different on one) - now I need to load one into the other and I'm getting some weird errors that look like the child swf is trying to use the same class definitions as the parent even though it should be in an entirely different namespace.
So - anyone have a tricky way of forcing the loaded swf to use the classes it's compiled with rather than the ones already defined in the parent swf (and vice versa) or do I need to refactor all my stuff?
So I know you can assign a base class to a library definition within the Movieclips library information field but If I have 30 items in the library and I change the Base class this becomes a pain in the ass, can this be done programmatically when I instantiate the library definition?
var new_shiz:MyItem1 = new MyItem1(); // Needs to have a generic base class of MyItem
