The MfcEmbedApp creates BrowserFrames 2. BrowserFrame creates the toolbar, statusbar, URLbar BrowserView etc. BrowserFrames implement the IBrowserFrameGlue interface using which new BrowserFrames can be created, statusbar updated etc. 3. BrowserView creates the embeddable browser instance and manages user interaction such as URL navigation etc. BrowserView connects the BrowserImpl with the BrowserFrame via the IBrowserFrameGlue interface 4. BrowserImpl implements the set of required/optional Gecko embedding interfaces Start by first looking at MfcEmbed.cpp Files: StdAfx.h - Includes the required Mozilla header files MfcEmbed.cpp - CWinApp derived class - Creates the browser's main frame window etc using the CreateNewBrowserFrame() and loads the HomePage - Makes the required NS_InitEmbedding() and the NS_TermEmbedding() calls in the app's InitInstance() and ExitInstance() functions - Keeps track of the list of new BrowserFrames created which it cleans up properly in ExitInstance() BrowserFrm.cpp - This is the browser's Frame window i.e. the one with the "chrome" - with the toolbar, urlbar etc. - Creates the toolbar, URLbar, statusbar, progressbar also the browser's view window. BrowserFrameGlue.cpp - Implements the IBrowserFrameGlue interface. This interface contains platform specific implementations of functions to update the statusbar, creating new browser frames etc. Embedded browser's callbacks use this interface when needed BrowserView.cpp - Creates the embedded browser object and handles most aspects of the embedded browser interactions - like URL navigation, clipboard interactions etc - Also has code to keep the menu/toolbar/statusbar UI items up to date - It's the view which conntects the BrowserFrame to the BrowserImpl (see below) by passing it the pointer to IBrowserFrameGlue BrowserImpl*.cpp - Implements the required and/or optional embedded browser interfaces (BrowserImpl.cpp implements the set of interfaces which are required by Gecko of all embedding apps. The other interfaces implemented in the BrowserImpl*.cpp files are optional) - Calls on the statusbar/progressbar update functions exposed via the IBrowserFrameGlue in response to the nsIProgressListener interface callbacks Dialogs.cpp - Contains dialog box code for displaying Prompts, getting passwords, getting username/passwords etc - Contains the CFindDialog class - used for searching text in a web page winEmbedFileLocProvider.cpp, ProfilesDlg.cpp, ProfileMgr.cpp - Profile management related code (by Conrad Carlen) MfcEmbed.htm - This is a simple test harness for excercising some of the implemented interfaces . For ex, the nsIWebBrowserChrome. - Open the file in mfcemed by typing the following in it's location bar. For ex: file:///c:/tmp/mfcembed.htm - Read/Click on the links on that page more info - This test page is just a start and will add more test case to it over time makefile.win - We define "_AFXDLL" and for the compiler and specify "-SUBSYSTEM:windows" for the linker using LCFLAGS and LLFLAGS, respectively - We also define "USE_SINGLE_SIGN_ON" to enable the single sign-on support mfcembed.dsp and mfcembed.dsw - These VisualStudio workspace/project files can be used to open/build this sample inside of the VC++ IDE
