MFC集成CEF

概要

• CEF源码下载：https://bitbucket.org/chromiumembedded/cef/downloads/?tab=branches

• CEF已编译文件下载：https://cef-builds.spotifycdn.com/index.html
  其中包括已编译的libcef.lib及其他必要文件，参考目录下的README.txt文件；需要把Release和Resoueces中的文件放到执行目录下。同时包括libcef_dll源码及编译环境，编译参考该目录下的CMakeLists.txt文件。

• 编译libcef_dll需要先用CMake(https://cmake.org/download/)生产编译环境，然后用VS进行编译就可以了

  • 执行 cmake -G “Visual Studio 11” .. (使用VS2012)

集成

CXXXApp

CXXXApp::InitInstance调用

bool CXXXApp::InitializeCef()
{
    //return true;
    // Initialize Chrome
    m_CefApp = new CefMfcCefApp;
    CefMainArgs mainargs(m_hInstance);
    void* sandbox_info = NULL;

    // See if this is a Chrome process starting. If so, we're done with our (and MFC) initialization.
    const auto exit_code = CefExecuteProcess(mainargs, NULL, sandbox_info);
    if (exit_code >= 0)
        return false;

    CefSettings settings;
    settings.multi_threaded_message_loop = false;
    settings.no_sandbox = true;
    return CefInitialize(mainargs, settings, m_CefApp.get(), nullptr);
}

CXXXApp::ExitInstance()调用

void CXXXXApp::UninitializeCef()
{
    CefShutdown();
}

消息循环，重载PumpMessage

不调用会导致无法显示网页内容
BOOL CUniOPMClientApp::PumpMessage()
{
BOOL ret = __super::PumpMessage();
// Cef Message
CefDoMessageLoopWork();
return ret;
}

将CCefBrowserEventHandler集成到工程中

此类主要实现CefClient，可以通过多层继承控制/访问其他接口
后续直接使用此类进行实例化

集成到CDialog

CefRefPtr m_pClient;

初始化 CXXXDialog::OnInitDialog()

    CefRefPtr<CCefBrowserEventHandler> client(new CCefBrowserEventHandler(this));
    m_pClient = client;


    CRect rt;
    GetClientRect(&rt);
    CefWindowInfo windowInfo;
    windowInfo.SetAsChild(GetSafeHwnd(), rt);
    CefBrowserSettings browserSettings;
    CefBrowserHost::CreateBrowser(windowInfo, client, (LPCTSTR)m_szSSOUrl, browserSettings, NULL);

大小变化 void CXXXDialog::OnSize(UINT nType, int cx, int cy)

    if (m_pClient.get())
    {
        CefRefPtr<CefBrowser> browser = m_pClient->GetBrowser();
        if (browser)
        {
            CefWindowHandle hWnd = browser->GetHost()->GetWindowHandle();
            ::MoveWindow(hWnd, 0, 0, rect.Width(), rect.Height(), TRUE);
        }
    }

窗口关闭时 void CXXXDialog::OnClose()

    if (m_pClient.get())
    {
        bool force_close = true;
        m_pClient->CloseAllBrowsers(force_close);
    }
