А интернет в Онтарио ограничен и примеров найти никак?

import mx.utils.Delegate;

myButton.onRollOver = Delegate.create( this, myFunction );

function myFunction()
{
    this.createTextField("mytext", this.getNextHighestDepth(), 10, 10, 200, 100);
    mytext.multiline = true;
mytext.wordWrap = true;
    mytext.border = true;

    var format1:TextFormat = new TextFormat();
    format1.letterSpacing = -1;

    var format2:TextFormat = new TextFormat();
    format2.letterSpacing = 10;

    mytext.text = "Eat at \nJOE'S.";
    mytext.setTextFormat(0, 7, format1);
    mytext.setTextFormat(8, 12, format2);
}
