I have various custom component instances in my flex app. I want to loop through them recursively and get their instance Ids. The recursive part is very important to me. I have tried doing this, but it didn't do recursive:
for each (var myItem:* in this.MasterContainer.childDescriptors)
{
trace(myItem.id);
}
I have a Flex component that is a view of a data Object that recursively has a reference to itself.
For example if you had an Employee class that references a boss field of type Person, I'd like to nest the same view for that Boss. This shouldn't be an infinite recursive relationship (e.g. I'd only be viewing the boss field of each object).
I've tried creating an MXML component that references itself but when I run it locks up (seems like it gets into a recursive loop).
Is there anything you can do like includeInLayout conditions that will make sure it doesn't even instantiate that component.

I have a canvas component called myCanvas and I instantiated it with
var myCanvasPage:myCanvas = new myCanvas;
this.addChild(myCanvasPage);
Then I want to essentially reload myCanvasPage later on. In effect I want to do this:
this.removeChild(myCanvasPage);
var myCanvasPage:myCanvas = new myCanvas;
this.addChild(myCanvasPage);
except instead of creating a new instance of myCanvas, I want to use the already created instance of myCanvas and essentially reload or re-create it but making sure that the instance name and references to it remain the same.
So, I create standard AS3 flex project. In constructor goes only start();
rest of functions are basically this:
private start():void { f1();}
private function f1():void { f2();}
private function f2():void { f1();}
And it's standard recursion. SWF either breaks or loops as many times as I tell it. One f calls the other, which calls first... I do not want that.
I want f1 to do some stuff, calls f1 and closes itself. Than f2 works, calls f1 and closes. And so on.
Like having 2 sets of code that loops through.
What's the cleanest way to do that?

I have a component "child" which has a cancel button. Now this component is placed in a state called "newChildComp" I also have another component called "parent". In the parent component, i have a button that dispatches an event. Here is the event code:
[Code].....
so, basically,i am checking to see if the cancel button component in the Child component, while i am still in the parent Compoent, was clicked, if it was clicked, call the cancelButtonHandler. The problem is by the time the addNewChild handles the event, that cancel button was still null. My question is how do i solve this without using the itemCreationPolicy on the cancel button?
I did an ActionScript 3 version of my old algorithm made in c language to solve the �Tower of Hanoi� puzzle.
The problem is that I knew how to show the intermediary steps in c language but I don�t know how to do that in ActionScript 3.
The below .as file code uses just three disks of successive bigger diameters ( and different colors ) created as MovieClips in Flash which must move from the first peg to the third one, through appropriate moves, in such way that they end up piled up in the same crescent order as they were in the first peg.
The way the code is written just shows the beginning disks position and the end result but not the intermediary steps.
I want this code being capable to show the successive disks positions on the pegs in each step of the process, each time I right-click the mouse.[code]...
I'm working on a script and I've run into a coder's writing block so-to-speak. I have an array of twenty object (with attributes). I want to loop through the array and for each object, update some text fields, create a tween, pause, and create another tween (i.e. fade in / fade out). I tried working with the timer class but the for loop, as expected, keeps on rollin' after the function has been called by the listener.
View 10 RepliesI have a basic for loop to loop through buttons and set some stuff and onPress handlers:[code]However, as I noticed, all buttonsthen link to one and same frame - all point to last i + 1 - Is there any possibility to call gotoAndStop with "static" Number, so in next iteration, it won't change?[code]
View 1 RepliesI have this code.
for (i=1; i<6; i++) {

this["unit"+i].onRelease = function() {
trace("Unit number " + i + " was pressed");
};}
I want to trace the number (i) of the button that is pressed. But no matter what button I press, I always get the value '6' on my trace. Isn't there a way to store the a value for i in each movie clip attached?
i have this from as2, where i can create many buttons on stage and loop. then create a function that applys to all the buttons
Code:
for (var i = 1; i <= 3; i++)

I hope I am clear enough. My data set is populated I have

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.

I am just learning how to use Flash AS3. I have made a very basic animation that is a circle with a slice in it that grows larger over a couple of seconds until it is about a quarter of the size of the circle. It is designed for my research subjects to watch and follow for range of motion and speed as they complete a leg exercise task. I used a basic for loop in the animation to repeat it 10 times, then a frame appears that says "Set Complete." I would like to add a repetition counter to the screen so that subjects know which rep they are on throughout the animation. I know that I have to use a dynamic text box to do this, but I don't know where to put the script so that the new counter number will appear on the screen after each loop. Here is what I have so far for script:
Action Layer first frame of loop:
var count: Number=0;
Action Layer last frame of loop:
count++;
if(count<=9){

I am wondering if anyone has experience this problem before:

I was experiencing some other "strange" behavior so I'm wondering if my code is getting too long. Maybe I'm running into some kind of limit. Has this happened to anyone else? Anyone know of some fixes? The loop is in a _global function, could that be causing a problem? other than that, the code is on line 4420 of the actionscript coding interface.
- I have two textArea components on the stage
- I need to figure out what textArea component is in focus when clicking on it
How do i make it so that it can figure out the instance name of the text area component in focus so i can preforme some code? I tried the following code but it doesn't seem to work.

so I have writing a function that returns objects on the stage and puts them into an array. and the function works fine until i call the function on more than one object name, meaning if im in the root class, and I call this function on object1 lets say it will add all the object one's from the stage, but if i call it on object2 it will throw an error, which makes some sense, i guess it means that it is not adding it to a unique array, but im not sure how to do that. would it be a good idea to maybe make a multidimensional array? if that is the case would it be too slow?

I'm building a top view 2D map, that it's objects are stored on the server.The kind of objects are 10 and might be a photo, label, button, lists, mix of them or labels with tooltips.The component must request the "areas" that are missing on screen.An area is 1000x1000 px and is cached in flex.To move in the map, will be like in google maps (drag-and-drop).I should be able to have another list and move objects from one to another using drag-an-drop on objects. Ex.: I grab an objects from a list and I move it on this map, I release the mouse button and the item is placed there.Now the problem is: I build a custom component for this trying to emulate the item renderer for performance and recyclage, implement drag-and-drop on objects and request the areas that are missing?
or
I extend the List component from spark and I add some features as multiple kind of itemrenderers and use recycle on them. Of course it must be able to request the missing areas on the screen and cache it's data.Maybe create a custom layout is needed too.What I need is something that must be really fluid, so the lighter this component is, the better.
UPDATE: *There will be not any object over another.
*I will not use hitTest on bitmaps because all bitmaps are wrapped in another component,as they,for now are itemrenderers.
Anyway I already begin to do this using a class that extends the SkinnableDataContainer and a custom layout. As the layout is not like a grid, is sparse, random items at diferent points(x, y).How to get the localX and localY, relative to item renderer and not to the Spark List, from a DragEvent in Flex 4?
I have two components. One is called "InsideComp" and one is called "OutsideComp". OutsideComp has InsideComp as one piece of its component, and in my main MXML file, I have embedded an instance of OutsideComp. How do I access a public variable of InsideComp within my main MXML file?In Actionscript, I could just do something like:OutsideComp.InsideComp.valToChange = 5; But I dont know how to do it in MXML. I know this is probably an easy question.

the situation | an instance of the DateChooser component reads an xml file which houses info for homework assignments and their due dates. if there is a due date, make sure that date is highlighted on the DateChooser component. from what i've been told, the xml file stores urls which will tell if there is s/thing due on a particular date. the xml file | very simple, has an <activity> element with a 'date' attribute, i.e.
[Code]...
my remaining questions | What needs to happen as soon as the xml file is loaded? i.e. do i call a function which parses the xml data and puts it into an array? then the DateChooser component iterates thru the array looking for boolean values noting if there is an activity or not and if so, on which day. if it finds one, it sets its highlight property to true for that particular day. i'm setting up the xml file correctly.
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 think I have the recursion working properly, but I'm not able to get the originally requested item's property set to the right value.The goal here is to find the topmost parent (or "ancestor," depth = 0) of the nested item (a taxonomy based on Dictionary "parent" attributes), and assign that originally requested nested item's "ancestor" property accordingly.For instance, in
Apples
- Red
- - Empire
- - - Fresh
"Fresh"'s ancestor should be set to "Apples." While I'm attempting this on an "on-demand" and individual basis, I'm open to a solution that tags all children that are related to the same ancestor in one fell swoop or for statement, since that would probably be more efficient.
REQUEST
for (var mc:Object in taxonomy) {
var term = taxonomy[mc];[code]....
As you can see, while the recursion does find the root, the originally requested item still gets the default value.

<root>
<node>
