Auto resize box of input text

Hi.

According to the video attached, do you want to resize the text box vertically, right?

Please try something like this:

import flash.events.Event;

var initialTFHeight:Number = yourTF.height;
var tfBottomOffset:Number = 50; // make sure the last line will be visible

function resizeTFVertically(e:Event):void
{
	// resize the text box according to the text height but clamping the value to a minimum
	e.currentTarget.height = Math.max(e.currentTarget.textHeight + tfBottomOffset, initialTFHeight);
	e.currentTarget.scrollV = 1;
}

yourTF.multiline = true; // set this value to true here or in the Properties panel
yourTF.addEventListener(Event.CHANGE, resizeTFVertically);

I hope this helps.
