Attached code is an example of how to use Google transliteration
feature in certain html textboxes. I need to enable the same
transliteration feature for a flex application. Is there a way
I could do it?

<html>
      <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
        <script type="text/javascript" src="http://www.google.com/jsapi">
        </script>
        <script type="text/javascript">
 
          // Load the Google Transliteration API
          google.load("elements", "1", {
                packages: "transliteration"
              });
 
          function onLoad() {
            var options = {
              sourceLanguage: 'en',
              destinationLanguage: ['hi','kn','ml','ta','te'],
              shortcutKey: 'ctrl+g',
              transliterationEnabled: true
            };
 
            // Create an instance on TransliterationControl with the required
            // options.
            var control =
                new google.elements.transliteration.TransliterationControl(options);
 
            // Enable transliteration in the textfields with the given ids.
            var ids = [ "transl1", "transl2" ];
            control.makeTransliteratable(ids);
 
            // Show the transliteration control which can be used to toggle between
            // English and Hindi and also choose other destination language.
            control.showControl('translControl');
          }
          google.setOnLoadCallback(onLoad);
 
        </script>
      </head>
      <body>
      <center>Type in Indian languages (Press Ctrl+g to toggle between English and Hindi)</center>
        <div id='translControl'></div>
        <br>Title : <input type='textbox' id="transl1"/>
        <br>Body<br><textarea id="transl2" style="width:600px;height:200px"></textarea>
      </body>
    </html>

you can connect javascript to you flex appliction (you can find a great example over [http://www.switchonthecode.com/tutorials/flex-javascript-tutorial-simple-interaction). In this case there is a problem though. When you want to use data form an external domain, the domain should have a crossdomain.xml file in it's root (http://labs.adobe.com/wiki/index.php/Flex:Accessing_Data).

Thanks for your help.
I am attaching the working flex code and the html wrapper here.

        <mx:Script>
                <![CDATA[
                        import mx.rpc.events.ResultEvent;

         public function callWrapper():void {
            var s:String;
            if (ExternalInterface.available) {
       ExternalInterface.addCallback("g", g);
               var wrapperFunction:String = "initialize";
               ExternalInterface.call(wrapperFunction,text1.text);
 
            } else {
               s = "Wrapper not available";
            }
            trace(s); 
         }
         public function g(str:String):void
         {
            text1.text = str;
         }
 
                        ]]>

        <mx:Button x="75" y="50" label="Enter some text and click this button to see the transliteration output" click="callWrapper()" height="37"/>
