Adding Sprites and scrolling them

Hi all,
I just started learning AS3 :) I was just trying out something.To read values from xml and make a drop down menu. I reached only this far

Actionscript Code:

import flash.display.Sprite;
import flash.text.TextField;
import flash.events.MouseEvent;

var i:Number = 0;
var sp:Sprite = new Sprite();
var sptxt:TextField = new TextField();
stage.addEventListener(MouseEvent.MOUSE_DOWN,addMore);

function addMore(e:MouseEvent):void {
    sp.name = "sp"+i;
    sptxt.name = "sptxt"+i;
    this.y+=10;
    //sptxt.addEventListener(MouseEvent.CLICK,EditMe);
    sptxt.text="this is the "+i+"th text";
    addChild(sp);
    sp.addChild(sptxt);
    trace("sp="+sp.name);
    trace("sptxt="+sptxt.name);
    trace("i="+i);
    i++;
}
/*
function EditMe():void {
    sp.sptxt.type=TextFieldType.input();
}
*/

What I did is that,When you click on the stage It will add a new spirte, sp with name sp0,sp1 ... and adds sptxt0,sptxt1... inside sp0,sp1... respectively.I put

Actionscript Code:

this.y+=10;

so that each sp will come along down like a drop down.

And

Actionscript Code:

EditMe()

is a function to make the text field in sp editable.Like if i click sp0,its text,ie sp0.sptxt0 must become editable.But its not working,am getting error as Access to undefined property :(

Another problem is that am getting output as "this is 0th text" then when i click again,it erases all things and adds "this is 1th text" at y+=0.Its not showing "this is 0th text" above that line. :( ...

Please help.

Btw One more thing.I think I know how to read XML values into those sptxt0,sptxt1 etc,but how can i make them scroll? Using the Scroll() on sp? or another container is needed?

Nobody knows?THen I am happy to share my version of the solution

Actionscript Code:

import flash.display.Sprite;
import flash.text.TextField;
import flash.events.MouseEvent;

var i:Number = 0;
var inc:Number = 10;
var sp:Sprite = new Sprite();
var sptxt:TextField = new TextField();
stage.addEventListener(MouseEvent.MOUSE_DOWN,addMore);

function addMore(e:MouseEvent):void {
    this['sp'+i] = new Sprite();
    this['sptxt'+i] = new TextField();
    this['sptxt'+i].text="this is the "+i+"th text";
    this['sptxt'+i].y+=inc;
    this['sp'+i].addEventListener(MouseEvent.MOUSE_DOWN,EditMe); 
    addChild(this['sp'+i]);
    this['sp'+i].addChild(this['sptxt'+i]);
    trace("sp="+this['sp'+i].name);
    trace("sptxt="+this['sptxt'+i].text);
    trace("i="+i);
    trace("x="+this['sptxt'+i].x);
    i++;
    inc += 10;
}

function EditMe(e:MouseEvent):void {
    this["sptxt"+i].type=TextFieldType.input();
}

Although I was able to create sprites and texts inside it,I am not able to refer to the textField to the corresponding sprite in EditMe()

Actionscript Code:

function EditMe(e:MouseEvent):void {
    this["sptxt"+i].type=TextFieldType.input();
}

Anyone knows that?

If I push all the sprites into an array, say

Actionscript Code:

var a:Array = new Array();
a.push(this['sp'+i]);

How can i refer to the text field inside 'sp'+i ?(ie 'sp'+i . 'sptxt'+i ?)

Instead of doing this:
<code>
this['sp'+i] = new Sprite();
</code>
why don't you do something like this:
<code>
var sprite_array = new Array();
sprite_array[0]= new Sprite();
</code>

ah :) glad that you saw my mail...
If i do like that,how will i refer to its child text field?Like if user clicks sprite_array[0],
how will i know that its sprite_array[0] and can access
sprite_array[0].text_array[0]?

Anyway to return array index?

in the listener function you can write something like

Actionscript Code:

e.target.text_array[0];

assuming "e" refers to the event object which is passed to the listener as an argument.

But if we are not sure if its 0 or anything else?To return the array index can we use

Actionscript Code:

getIndex()

?
like

Actionscript Code:

location = sprite_array.getIndex(e.target);
sprite_array[location].text_array[location];

Will that select sprite_array[8].text_array[8]; if i click on the 8th sprite?

Yep, hopefully.
