Say I have a class B that extends class A.In class A, I have a variable that I've declared to be a function, which gets defined in the constructor. Now, in class B, is there any way to reference that function with the use of super.functionName()?
View 1 RepliesIs it possible to call a method in the super class of a super class? I tried the above and it doesn't work, unsurprisingly. Only way I've been able to do it is to store a reference to a super.someMethod in the super Class (eg. var superMethod: Function = super.someMethod) and call that instead. Seems reasonable and it works but wonder if there is an in-built method for doing this?

I am running into problems with a custom class I have written. I did a search on the error message here, but didn't find a solution that quite fit what was going on. I think my problem is in how I'm tying the class to the movie script in the library, but I'm not sure.
I have a MovieClip symbol in the library named nav1. It is set to export, with the class name being nav1, and the base class being the custom class I created. In the base class I have a function:

I'm trying to make a CustomLoader class that extends another class.In the contructor of my CustomLoader, i need to call super(myLoader:Loader) where myLoader is a Loader object. Problem is I need to listen to the complete event of the loader before passing it or i'll get an "Error #1009: Cannot access a property or method of a null object reference". but if i put super() in a handler function i get an "Error 1007: A super statement can be used only inside class instance constructors."
Here's part of my code:
Code:

It's slower to call a function this way than calling it directly?
What I'm wondering is if the function names are all hashed, so calling it with bracket and string would just be a hash look up or is flash actually iterating through all the function names (and maybe all variable names) and doing string comparison to find the right function to call.
i got a class(class1) that extends another class (class2)...when something happens in super class, i need to update the class1, soi need to trigger a function in class1 from class2... I know is bad programming, but is that possible? I'm confused
View 0 RepliesI am trying to extend the new AutoComplete component from Adobe. In two different places I need to bypass the AutoComplete methods and get right at the ComboBox methods.
I was told that super.super.someMethod() works just like it does in Java. But I keep getting Compiler errors:1084: Syntax error: expecting identifier before super.Any suggestions other than just cutting and pasting the code and extending the AutoComplete superClass?
If I have three classes:
public class Example {
public function Example () {
}[code]............
You can see that the two last classes extend the first one, and both have the 'variable' property. In case that I have an instance of Example and I am sure it is also an ExtendedExample OR AnotherExtendedExample instance, is there some way to access the 'variable' property? Something like
function functionThatReceivesAnExtendedExample (ex:Example):void {
if(some condition that I may need) {
ex.func()

Is there a way to reference a function via a variable? In other words, instead of saying something like:
var theVar = someString + 'function';
if (theVar == 'functionName') functionName ();
to access it directly:
(someString + 'function') ();
using some kind of bracket notation?
i have a function that read a variable from a text file, yet i can only read the variable from within the function. How could i create a global variable or such that i can then read from outside of the function.

VARIABLE = Make.textVariable;

What's an example of calling a function through a reference (as opposed to directly)?
View 2 RepliesI thought I understood this stuff by now; the objects within a function are onlyaccessible within that same function, unless you return it to whatever called the function.However I dont think that you can do that for a function called with an eventlistner, so I set up what I thought was a global variable and set its contents within the function, thinking that the contents would be accessible later:
ActionScript Code:
var bmpd:BitmapData;
var URLReq:URLRequest = new URLRequest("sample.jpg");

Got a list of MCs being populated from an XML file. Basically a list of two different types of information. Some are type A, some are type B.
Want to have a couple buttons that filter based on type (so if I push the button for type A (called "typeAbtn" below), only those MCs appear and type B MCs go to _alpha = 0 or something).
Can't seem to come up with a function to do it. I can't figure out how to reference all my MCs from outside the first function correctly.
terrible attempt:
Code:
function showMCs() {
for (var j = 0; j<stuff.length; j++) {
MC = timeline_mc["MC"+j];

I am using a delegate sub-class to perform helper functions for the main app.I have passed all references to it that it needs and it works well apart from the following problem:I also want it to remove an event listener from the main pp.eg:thisStage.removeEventListener(MouseEvent.MOUSE_UP,preOutsideBoundsDragRelease);The compiler tells me I need a reference to "preOutsideBoundsDragRelease" within the removeEventListener statement.eg: "access of undefined property preOutsideBoundsDragRelease
View 1 RepliesI got this document class Main and a navbutton class. How can I connect a function from one AS3 document to another like this:
navbutton.as
removeObjects();
Main.as
function removeObjects(){
//code
}
I get this error: call to a possibly undefined method removeObjects.
i want to pass by reference so i can use this variable outside the function.
What im doing is creating a global variable such as var cont:int; and then in a eventListener like enter_frame (stage.addEventListener..) calling a function called "mover", this function modifies "cont" value and i just want to print this value modified. The issue is i cant pass the value by reference just by const :S. The function is void, but if i change it to return int, its useless because each time i call the function, the value i want to return its created each time with a new value, beacuse i need to declare it so.. I read i can use a var such as Object but i really dont get it (im used to c++ i have to say)

In AS2 I have several arrays constructed like this :
var myArray0:Array=new Array(value,value,value...)
var myArray1:Array=new Array(value,value,value...)
var myArray2:Array=new Array(value,value,value...)
var myArray4:Array=new Array(value,value,value...)
...
What I'm trying to do is use iteration to reference each array name to pass it into a function.
Like :
function doSomethingWithArray(arrayToPass){
...
}
//Later somewhere in For loop... :
_root["myButton"+i].onRelease=function(){
doSomethingWithArray(WHAT-THE-HELL-I-TYPE-HERE[i])

How would one get a reference of String global function (not class). According to language reference this function does exist (and I'm ready to believe it does), but, say and you have a:
Code:
function foo(bar:Function):void { ... }
How then would you pass that String to it?

This is because I believe it is referring the splashTimer1 function by "this".
How can I refer to parent frame there, so that I can remove its event listener.
