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 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 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 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 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 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 _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:
在项目属性,清单工具,输入输出中,指定刚刚新建的cef.manifest文件。重新生成,即可显示目标网页。
