Flex panel titleTextField.htmlText href link handler

Question

I am creating a custom panel in which, I want the titleTextField to have HTML text in which a word is clickable. I have below attached a mxml
component code with the HTML text for the title. I don't know how  to provide for a link handler for the link event. I would have thought that the titleTextField or titleBar would have provided for a link handler, but it does not appear to be so. I appreciate any help. 
Thanks, Ramesh

I found the answer in adding an EventListener listenign for the TextEvent.LINK event. The code is below.
<?xml version="1.0" encoding="utf-8"?>
<TextInputPanel xmlns="soapbox.util.*" xmlns:mx="http://www.adobe.com/2006/mxml"
    width="300" height="200"
    title="I want to learn"
    borderThicknessLeft="6" borderThicknessRight="6" borderColor="#395182" creationComplete="init()">
    <mx:Script>
        <![CDATA[
            private function init():void {
                this.titleTextField.htmlText = "I want to <font color='#0000FF'><a href='event:learn'>learn</a></font> | <font color='#0000FF'><a href='event:teach'>Teach</a></font>";
                this.titleTextField.addEventListener(TextEvent.LINK, learnHandler);
            private function learnHandler(event:TextEvent):void {
                trace("link clicked");
        ]]>
    </mx:Script>
</TextInputPanel>
