If an object, or say... a document class, creates an instance of a class (and stores it as a variable), and it doesn't pass any arguments to the constructor of the class, can that class object, by simply having a function of it called by the parent, tell who sent it that command/request? In other words, can a class object know who called it (such as it's parent) via a (seemingly) anonymous call?

How to call a function in a Class from another Class?but it was a bit hard to follow as it relates to my problem. One of the solutions worked, but was commented as being bad form, and another did not work, so I want to make sure I structure my code properly.
I need to get a javascript var in my Flash application. I like to be able to just set a variable in the javascript (client constraints) rather than define a function.
Can this be done? I am trying to use the ExternalInterface.call()
AS:
ExternalInterface.call("function(){return window.someVar}", null);
JS:
var someVar = "Test";
This does not work and I suspect it is because the ExternalInterface.call() does not like the anonymous function.
I have a movieClip with one frame on the timeline containing one child whose instance name is "myContent"I am using this function to swap "myContent" with any number of possible class instances.

one of my problem is that how do i call the instance name of a button from my child.swf to my parent.swf
i have four buttons from my child.swf where when i click btn1 it will load superchild.swf but i want to load that superchild.swf to my parent.swf, like instead btn1 calls superchild.swf to load, btn1 will call parent.swf then on parent.swf it will distinguish that btn1 was click from child.swf and it will now load superchild.swf.
Lets say I have a Main Document Class called Main. I also have a child class called childClass that call a function from the Main class and is also imported in the Main class. How should I call the function? I tried this , but when calling the function, it's getting me error.

i have a main movie. i use a loader to load a "example.swf" file. then i place that file inside a holder movieclip. in example.swf, i have an instance of a class i just wrote. this class has some particular methods. from my main movie, i want to call the methods of the instance of my class i have in example.swf. how can i do that??? i know it's a kind of casting, but none seems to work.

When I try to use this code to call a function for every instance of a certain class I get an error saying that there is a "call to a possibly undefined method removeInstance through a reference with static type flash.displayObject".

I make a movie clip in the library ( a button with a text field on it ) and export it for actionscript. Then I create an instance of the object using code ( myButton = new Button1(); ).And then I want to access and change the text field ( whose instance name is "myField" in Flash ) afterwards.Is that possible, or I have to create a custom class for the object, or just create an entire button dynamically?
Because what I have tried until now doesn't work.
Code:
var button1:button_test1 = new button_test1();
button1.x = stage.width / 2;
button1.y = stage.width / 2;

This questions is for all movie clips: is there a way to access a movie clip's objects with actionscript after you have created (with code) an instance of that object (which was designed in flash, and exported for AS) ?

I have two child classes ClassA and ClassB both inherit the same base class.
I also have a function that has a parameter which could be an instance of either child classes.
function Test(instance):void //instance is either a ClassA or ClassB instance

instance.DoSomething();
}
However, when I run the test, it's always the BaseClass.DoSomething() get called. How can I use the same function (DoSomething()), but call child class function instead of the base class one?
How can I get the instance of the class to call the dispatchEvent for the postTrace function.

View 1 RepliesIn c++ if I have a function that takes a class I have defined elsewhere as a parameter like so:void moveto(CPoint2D point) { ... }I can invoke it and pass along data to it like this:moveto(CPoint2D(0,0));basically creating the object and invoking it's constructor to be passed to the functionIs there an equivalent to this in AS3?if I have a function like this:function initialize(min:Point, max:Point): void { ... }how do I do something along the lines of :initialize(Point(0,0), Point(10,10))This throws an error im assuming because it thinks I want to cast something to a point and the notation I found earlier to do something similar only seemed to work if using the basic Object class.
View 1 RepliesIf I pass a MovieClip through as an argument in the constructor for a class I am writing, how do I create a new instance of that MovieClip from within the class?
The MovieClip has a custom class name that is unknown to the class I am writing, it is simply passed through as a MovieClip.
I tried:
Code:
_class = Object(mc).constructor;
_mcArray[i] = new _class;
How can I instantiate another class object from a class instance? In the code below (which doesn't work) I'd like the function to return a new class instance based the passed argument's class. In other words, I want the function to return a new instance of MySprite without having to call new MySprite();.
var mySprite:Sprite = new MySprite();
var anotherSprite:Sprite = makeAnotherSprite(mySprite);
function makeAnotherSprite(instance:Sprite):Sprite {
return new getDefinitionByName(getQualifiedClassName(instance));
}

View 4 RepliesI have created some (TextInput, ComboBox, CheckBox) Component instances (created as a public objects) in a Document class and added them to the stage.
Now I have created a custom class for a movieclip in library and instantiated it in the document class (also a public instance).
I need to access the component instances in the custom class. How to do this ?
Also, Is it a good practice to use ENTER_FRAME event frequently ? because if I can't access the above components instances in the custom class then I will be left with no choice but to use ENTER_FRAME event in the document class every time I need to change some value in the components...
class Foo {
public function bar():void { ... }

I have a collection of movieclips, I would like to create a clone (a new instance) of a instance everytime I create a new object.
For example
var s:Star = new Star(); // star-shaped movielcip
addChild(s);
// then I want to duplicate an instance of s and add it beside s
For an example like above, it's simple enough to create a new instance with a different name and just add it to the display list. But I have a list of objects I would like to clone as a group...?

Does creating a new instance of an Object that uses an identical name to an older instance, delete the previous instance? Or should the original instance be deleted first? The code uses a ridiculous amount of XML vars. Isn't it less memory intensive to parse the XML and save the properties to an Object, and then delete the XML Object, rather than keep the XML Object around and reference it's child nodes directly? Is it better form to break up a huge XML file (>600lines/3200vars) into smaller chunks?
View 1 RepliesI am using Flex 4 and for whatever reason I cannot get the following code to work which happens inside of a ListEvent handler for a dataGrid:
_tempRule = DataGrid(event.currentTarget).selectedItem as Rule;
Rule is a custom class, and the above code always returns null. The dataprovider for the datagrid is an ArrayCollection. If I try to wrap the above code to make it like the following:
DataGrid(event.currentTarget).selectedItem as Rule
I get this error:
TypeError: Error #1034: Type Coercion failed: cannot convert Object@e15a971 to com.mycompany.arcc.business.Rule

I have a pointer to a Class object like so:

if (c.can_build(this, qualifier)) {return true;}
return false;

I have a custom class and inside its constructor, I need "x" and "y" arguments passed on. Now when I call the class and create and instance of it, flash should pop up "the code hinting"...(but it doesn't), or am I missing something???
