以下是Cef3嵌入MFC多文档视图的基本代码示例:
首先,在您的MFC多文档视图应用程序中创建一个CefApp派生类,如下所示:
```C++
class CMyCefApp : public CefApp
{
public:
CMyCefApp() {}
virtual void OnBeforeCommandLineProcessing(const CefString& process_type, CefRefPtr<CefCommandLine> command_line) override
{
// 设置Cef3的配置选项
command_line->AppendSwitch("disable-gpu");
command_line->AppendSwitch("disable-gpu-compositing");
command_line->AppendSwitch("enable-begin-frame-scheduling");
command_line->AppendSwitch("enable-media-stream");
command_line->AppendSwitch("enable-system-flash");
}
IMPLEMENT_REFCOUNTING(CMyCefApp);
};
```
然后,在您的视图类中创建一个CefBrowser对象,并将其添加到您的视图窗口中,如下所示:
```C++
#include "include/cef_client.h"
#include "include/cef_browser.h"
#include "include/views/cef_browser_view.h"
#include "include/views/cef_window.h"
class CMyView : public CView, public CefClient
{
public:
CMyView()
{
// 创建CefBrowser对象
CefRefPtr<CefBrowser> browser = NULL;
CefWindowInfo window_info;
CefBrowserSettings browser_settings;
// 设置CefBrowser窗口信息
CefRect rect(0, 0, 800, 600);
window_info.SetAsChild(GetSafeHwnd(), rect);
// 创建CefBrowserView对象
CefRefPtr<CefBrowserView> browser_view = CefBrowserView::CreateBrowserView(this, browser, window_info, browser_settings, NULL);
// 添加CefBrowserView到视图窗口
m_pWnd = browser_view->GetWindowHandle();
SetWindowPos(m_pWnd, NULL, rect.x, rect.y, rect.width, rect.height, SWP_NOZORDER);
}
virtual CefRefPtr<CefClient> GetClient() override
{
return this;
}
// ...其他CefClient接口方法的实现
private:
HWND m_pWnd;
};
```
最后,在您的应用程序中,将Cef的启动和关闭代码添加到InitInstance和ExitInstance方法中,如下所示:
```C++
BOOL CMyApp::InitInstance()
{
// 初始化Cef3
CefMainArgs main_args(GetModuleHandle(NULL));
CefRefPtr<CMyCefApp> app(new CMyCefApp());
CefInitialize(main_args, app.get(), NULL);
// ...其他初始化代码
return TRUE;
}
int CMyApp::ExitInstance()
{
// 关闭Cef3
CefShutdown();
// ...其他清理代码
return CWinApp::ExitInstance();
}
```
以上就是Cef3嵌入MFC多文档视图的基本代码示例。注意,这只是一个基本示例,您可能需要根据您的实际需求进行修改和扩展。
