- The |frame| parameter to HandleLoadStart and HandleLoadEnd will always be non-empty. The CefFrame::IsMain() method can be used to check if the notification is for the main frame. The |isMainContent| parameter has been removed. git-svn-id: https://chromiumembedded.googlecode.com/svn/trunk@202 5089003a-bbd8-11dd-ad1f-f1f9622dbc98
