Initial Code
// When you are in a for loop, create new items and and try to measure the height of an item.
// And position items vertically.You need to remember the previous item, the fastest way to do this is to have a runningY var declared outside the for loop with an initial value of zero.
//See comments in code for further explanation.
var runningY:Number = 0;
for (var index:int = 0; index < 4 ; index++) {
var _textheader:TextField = new TextField( );
_textheader.text = "Text";
_textheader.autoSize = TextFieldAutoSize.LEFT;
_textheader.x = _background.x - _background.width / 2 + TOP_LEVEL_OFFSET_X;
// First iteration runningY = 0;
// Second iteration runningY = 0 + textHeader.height +2; textHeader.height = 20
// Third iteration runningY = 22 + textHeader.height +2; textHeader.height = 40 -- mutiple lines of text
// Fourth iteration runningY = 64 + textHeader.height +2; textHeader.height = 20
// Fifth iteration runningY = 86
_textheader.y = runningY;
runningY += _textheader.height + 2; // textheader = 20
