Hello guys.
I have created my application, I created a mxml TitleWindow that recall in my application with a button. This is the code of mxml TitleWindow. But with this flex 3.

<?xml version="1.0" encoding="utf-8"?>
<mx:TitleWindow

paddingBottom="10"
    x="0"
    y="82"
    title="Table of Contents"
    dropShadowEnabled="true"
    dropShadowColor="Black"
    shadowDirection="right"
    shadowDistance="5"
    showCloseButton="true" xmlns:ns1="*">

<mx:Script>
