Выделение текста TextField

[madison]

Респект флеш мастерам

Вот, есть код(AS2) добавления в скобки выделенного текста из TextField,
помогите переписать под ActionScript 3.0

txt - name TextField
tr - button

txt.onSetFocus = txt_onSetFocusHandler;
txt.onKillFocus = txt_onKillFocusHandler;
 
tr.onRelease = tr_onReleaseHandler;
 
var beginIndex:Number;
var endIndex:Number;
 
function txt_onSetFocusHandler(oldFocus:Object):Void
{
	onMouseUp = onMouseUpHandler;
}
 
function txt_onKillFocusHandler(newFocus:Object):Void
{
	delete onMouseUp;
}
 
function onMouseUpHandler():Void
{
	beginIndex = Selection.getBeginIndex();
	endIndex = Selection.getEndIndex();
}
 
function tr_onReleaseHandler():Void
{
	if (beginIndex == endIndex)
		return;
 
	var newString:String = '(' + txt.text.substring(beginIndex, endIndex) + ')';
	txt.replaceText(beginIndex, endIndex, newString);
 
	delete beginIndex;
	delete endIndex;
}

Узнаю своё дитя =) http://flasher.ru/forum/showthread.php?p=839737

tr.addEventListener(MouseEvent.CLICK, tr_clickHandler);
 
function tr_clickHandler(event:MouseEvent):void
{
	var beginIndex:int = txt.selectionBeginIndex;
	var endIndex:int = txt.selectionEndIndex;
 
	if (beginIndex == endIndex)
		return;
 
	var newString:String = "[" + txt.text.substring(beginIndex, endIndex) + "]";
	txt.replaceText(beginIndex, endIndex, newString);
}
