This sample shows how to embed Mozilla from within
|
|
an MFC Windows application
|
|
|
|
Mainly demonstrates the use of the following interfaces:
|
|
|
|
nsIWebBrowserChrome
|
|
nsIEmbeddingSiteWindow
|
|
nsIWebProgressListener
|
|
nsIContextMenuListener
|
|
nsIPrompt
|
|
nsIWebBrowserFind
|
|
|
|
General Overview:
|
|
-----------------
|
|
|
|
1. 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
