Thanks for your help but GetMainWidget return the parent widget of
chrome window and not chrome widget pointer.
I tried following code but that seems to be very complex ..
nsCOMPtr<nsIWebBrowser> webBrowser;
nsCOMPtr<nsIWebNavigation> webNavigation;
nsCOMPtr<nsIDocShell> docshell;
nsCOMPtr<nsIPresContext> presContext;
nsCOMPtr<nsIDOMWindow> contentWin;
nsCOMPtr<nsIDocument> doc;
nsCOMPtr<nsIContentViewer> ContentViewer;
nsIView *view = nsnull;
if (chrome)
{
BroPtr->chrome->GetWebBrowser(getter_AddRefs(webBrowser));
webBrowser->GetContentDOMWindow(getter_AddRefs(contentWin));
webNavigation =
do_QueryInterface(webBrowser);
docshell = do_GetInterface(webBrowser);
docshell->GetContentViewer(getter_AddRefs(ContentViewer));
if(ContentViewer)
{
nsCOMPtr<nsIDocumentViewer>
DocViewer(do_QueryInterface(ContentViewer));
if (DocViewer)
DocViewer->GetDocument(getter_AddRefs(doc));
docshell->GetPresContext
(getter_AddRefs(presContext));
if(presContext)
presContext->GetViewManager()->GetRootView (view);
view->GetWidget();
}
}

Subject: Re: Getting nsWindow from chrome
It looks like the documentation typedefs the nsWindow as an
nsBaseWidget.
So maybe you can try something like this:
//----------------------------------------------------------------------
----
---
nsIWebBrowser *piwbWebBrowser = nsnull;
nsIBaseWindow *pibwBaseWindow = nsnull;
nsWindow *pWindow = nsnull;
chrome->GetWebBrowser (&piwbWebBrowser);
piwbWebBrowser->QueryInterface (NS_GET_IID (nsIBaseWindow), (void**)
&pibwBaseWindow);
piwbWebBrowser->Release ();
piwbWebBrowser = nsnull;
pibwBaseWindow->GetMainWidget (&pWindow);
piwbBaseWindow->Release ();
piwbBaseWindow = nsnull;
//Do your GUI stuff here
pWindow->Release ();
pWindow = nsnull;
//----------------------------------------------------------------------

That should work for up to at least GetMainWidget(), but I'm not sure
about
actually getting an nsWindow object from that. I hope that helps. If I
find anything else I'll reply again.
