// File Overview....
//
// This file has the IBrowserFrameGlueObj implementation
// This frame glue object is nested inside of the BrowserFrame
// object(See BrowserFrm.h for more info)
//
// This is the place where all the platform specific interaction
// with the browser frame window takes place in response to
// callbacks from Gecko interface methods
//
// The main purpose of this interface is to separate the cross
// platform code in BrowserImpl*.cpp from the platform specific
// code(which is in this file)
//
// You'll also notice the use of a macro named "METHOD_PROLOGUE"
// through out this file. This macro essentially makes the pointer
// to a "containing" class available inside of the class which is
// being contained via a var named "pThis". In our case, the
// BrowserFrameGlue object is contained inside of the BrowserFrame
// object so "pThis" will be a pointer to a BrowserFrame object
// Refer to MFC docs for more info on METHOD_PROLOGUE macro
#include "stdafx.h"
#include "MfcEmbed.h"
#include "BrowserFrm.h"
#include "Dialogs.h"
