How to get parent window in extjs or window.opener equivalent in extjs?

Question

I am launching a window using HtmlPage.Window.Navigate(Uri, "_blank"); from silver light. I want to notify silverlight app from extjs unload event.

I am trying with window.opener from my extjs code in app.js

Ext.EventManager.on(window, 'beforeunload', function () {
            //window.opener is undefined here
            }

Is there any extjs equivalent for window.opener? Or How to get the parent window from extjs? I am trying with the sample http://www.codeproject.com/Articles/293515/Calling-Silverlight-Method-from-Javascript-and-Jav for calling silverlight method from javascript?

your questions is very confused...extjs event or browser event? unload event or beforeunload event? why do you need the opener reference? — Neil McGuigan, Oct 01 '12 at 17:52
I don't think this is an ExtJS issue but rather browser support. — dbrin, Oct 02 '12 at 22:50

Take a look at this question: window.opener alternatives
