How to get Text Input In Adobe AIR - actionscript-3

Question

I'm new to Adobe AIR and here is what i'm doing, (please note that i'm doing this by AS3 code:
Adding a VGroup to the Canvas control.
var vIncomeHeader:VGroup = new VGroup();
vIncomeHeader.width = 1326;
vIncomeHeader.height = 29;
vIncomeHeader.id = "vIncomeHeader";
canvasIncome.addChild(vIncomeHeader);
Creating and adding a HGroup to the VGroup created in step one.
Creating 5 TextInput and adding it to HGroup. First textbox is editable and rest are not editable.
var hfIncomeHeader:HGroup = new HGroup();
var txt:TextInput = new TextInput();
vIncomeHeader.addElement(hfIncomeHeader);
var lp:int =0;
var lp-inner:int =0;
for (lp=0; lp<10; lp++)
{
hfIncomeHeader = new HGroup();
hfIncomeHeader.width = 1326;
hfIncomeHeader.height = 29;
//Amount
txt = new TextInput();
txt.id = "txtAmount_" + lp;
txt.width = 120;
txt.height = 22;
txt.restrict = "0-9.\\";
txt.addEventListener(Event.CHANGE, txtChangeIncomeAmount);
hfIncomeHeader.addElement(txt);
for (lp-inner=0; lp-inner<4; lp-inner++)
{
//Income Type
txt = new TextInput();
txt.id = "txt_" + lp + "_" + lp-inner;
txt.width = 120;
txt.height = 22;
hfIncomeHeader.addElement(txt);
}
}
//txtChangeIncomeAmount
protected function txtChangeIncomeAmount(event:Object):void
{
// HOW TO Do IT
}
[Second and third steps are part of a for loop from 0 to 10]
Now, what I want to do is to write the number in first textbox and automatically fill the same number to other 4 textboxes of that HGroup.

Answer 1

You can set names to your TextInput and then get them by names. Something like that:
...
txt.name = "txt_" + lp-inner;
...
protected function txtChangeIncomeAmount(event:Event):void
{
var txt:TextInput;
for (var i:uint = 0; i < 4; i++)
{
txt = hfIncomeHeader.getChildByName("txt_" + i) as TextInput;
txt.text = (event.currentTarget as TextInput).text;
}
}
