Saying goodbye to bookshops

phani — Mon, 15 Aug 2011 17:30:29 +0000

Visiting Crossword, Landmark or Walden stores was my traditional way to buy books. Although i have tried infibeam and flipkart to buy books i was more comfortable going to the book store to buy books.

Recently i have been more active on flipkart website and been ordering books online. I have been getting great deals on the books which are not being matched at the offline stores. The service provided by flipkart is also awesome and i have been buying more books online. Looks like i wont be going back to bookshops.

Flex Focus issue

phani — Tue, 21 Sep 2010 15:15:07 +0000

I came across an interesting bug which is reproducible only in IE6 and IE7. I have a web page which has a SWF file embeded. There is a IFRAME in that web page and that IFRAME contains a HTML input field. There is also a Flex Text Field in the SWF file. Now the issue is the flex text field is not gaining focus after clicking on the HTML input field. There is a bug which was filed with adobe but closed without any resolution.

The SWF file and the HTML file are in two layers in the browser and focus is not getting passed to the SWF file from HTML in a IFRAME. So as a work around i needed to set the focus using javascript.

//Flex code
 private function gainCursor() : void
 {
      var textID:* = focusManager.getFocus() as TextInput;
      if (textID is TextInput)
         {
            ExternalInterface.call("deFocus");
            focusManager.setFocus(IFocusManagerComponent(textID));
         }
 }

// javascript function
function deFocus()
 {
      window.focus();
      window.document["YourSWFFilenamehere"].focus();
 }
