Win32程序是所有在windows系统上采用C++进行程序开发的系统子程序,是非常原生态的一种开发方式,大型软件一般会采用这种可以高度定制的方式来开发。在开发Win32程序时,面临需要嵌入浏览器的问题,可以采用嵌入libcef的方法来嵌入浏览器。本文测试环境采用VS2017+chromium-79.0.3945.88_windows64测试。

在VS2017中新建Win32窗口项目,如下图所示:
找到项目中对应文件,拷贝至Win32所在项目,如下图所示:
将对应文件添加至解决方案,如下图所示:
将包含文件和库路径添加至当前项目属性,头文件是项目文件夹下的include文件夹。
4.1.头文件夹
本文将编译好的libcef_dll_wrapper.lib和debug对应其他资源文件整理在一个目录,如下所示:
mfc项目添加库路径和库文件。如下图所示:
添加库文件:
libcef.lib libcef_dll_wrapper.lib opengl32.lib comctl32.lib rpcrt4.lib shlwapi.lib ws2_32.lib d3d11.lib glu32.lib imm32.lib kernel32.lib user32.lib gdi32.lib winspool.lib shell32.lib ole32.lib oleaut32.lib uuid.lib comdlg32.lib advapi32.lib
5.添加代码 5.1.修改浏览器窗口位置将simple_app.cc文件中的以下内容去除,这部分内容是显示浏览器窗口使用。
void SimpleApp::OnContextInitialized() { CEF_REQUIRE_UI_THREAD(); CefRefPtr<CefCommandLine> command_line = CefCommandLine::GetGlobalCommandLine(); #if defined(OS_WIN) || defined(OS_LINUX) // Create the browser using the Views framework if "--use-views" is specified // via the command-line. Otherwise, create the browser using the native // platform framework. The Views framework is currently only supported on // Windows and Linux. const bool use_views = command_line->HasSwitch("use-views"); #else const bool use_views = false; #endif // SimpleHandler implements browser-level callbacks. CefRefPtr<SimpleHandler> handler(new SimpleHandler(use_views)); // Specify CEF browser settings here. CefBrowserSettings browser_settings; std::string url; // Check if a "--url=" value was provided via the command-line. If so, use // that instead of the default URL. url = command_line->GetSwitchValue("url"); if (url.empty()) url = "http://www.baidu.com"; if (use_views) { // Create the BrowserView. CefRefPtr<CefBrowserView> browser_view = CefBrowserView::CreateBrowserView( handler, url, browser_settings, NULL, NULL, NULL); // Create the Window. It will show itself after creation. CefWindow::CreateTopLevelWindow(new SimpleWindowDelegate(browser_view)); } else { // Information used when creating the native window. CefWindowInfo window_info; #if defined(OS_WIN) // On Windows we need to specify certain flags that will be passed to // CreateWindowEx(). window_info.SetAsPopup(NULL, "test simple cef"); #endif // Create the first browser window. CefBrowserHost::CreateBrowser(window_info, handler, url, browser_settings, NULL, NULL); } }5.2.目标位置加入代码
在Win32中InitInstance函数内加入代码:
CefRefPtr<SimpleHandler> g_handler; BOOL InitInstance(HINSTANCE hInstance, int nCmdShow) { //初始化 //启用高分辨率,启动进程 CefEnableHighDPISupport(); void *sandbox_info = NULL; CefMainArgs main_args(hInstance); int exit_code = CefExecuteProcess(main_args, NULL, sandbox_info); if (exit_code >= 0) { return exit_code; } //关闭沙箱,浏览器初始化 CefSettings settings; settings.no_sandbox = true; settings.multi_threaded_message_loop = true; CefRefPtr<SimpleApp> app(new SimpleApp); CefInitialize(main_args, settings, app.get(), sandbox_info); hInst = hInstance; // 将实例句柄存储在全局变量中 HWND hWnd = CreateWindowW(szWindowClass, szTitle, WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, 0, CW_USEDEFAULT, 0, nullptr, nullptr, hInstance, nullptr); if (!hWnd) { return FALSE; } ShowWindow(hWnd, nCmdShow); UpdateWindow(hWnd); CefRefPtr<SimpleHandler> _handler(new SimpleHandler(false)); g_handler = _handler; CefWindowInfo window_info; RECT rect; GetWindowRect(hWnd, &rect); int w = rect.right - rect.left; int h = rect.bottom - rect.top; w = std::abs(w); h = std::abs(h); rect.left = 0; rect.right = w; rect.top = 0; rect.bottom = h; window_info.SetAsChild(hWnd, rect); //window_info.SetAsPopup(NULL, "hello"); CefBrowserSettings browser_settings; CefBrowserHost::CreateBrowser(window_info, g_handler.get(), "http://www.baidu.com", browser_settings, NULL, NULL); return TRUE; }
在Win32中退出函数内加入代码:
CefShutdown();6.加入manifest文件
以上做完之后,在测试的时候发现浏览器显示空白,需要加入manifest文件,内容如下:
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <compatibility xmlns="urn:schemas-microsoft-com:compatibility.v1"> <application> <supportedOS Id="{1f676c76-80e1-4239-95bb-83d0f6d0da78}"/> <supportedOS Id="{8e0f7a12-bfb3-4fe8-b9a5-48fd50a15a9a}"/>关注打赏
