MFC 实现richedit右键菜单的复制粘贴功能

     需要用到Richedit的右键菜单复制，粘贴功能。百度谷歌了一下，发现网上的文章都是零零碎碎，借鉴意义不大。于是，发扬我们桂电勇于挑战困难，努力进取的精神，终于完成了右键添加菜单和复制粘贴等功能。

   大致分三个步骤：1.MFC添加右键菜单；2.添加菜单消息响应函数；3.菜单消息响应里使用剪切板实现复制，粘贴功能。

1.MFC添加右键菜单 

1.建立一个基于对话框的的MFC程序。

2.Insert->Resource->Menu。

3.可以给menu改一个id，也可以不改。

4.把菜单搞成这样的(搞成别的样的也可以)。

5.在对话框对应的类上点右键 -> Add ClassWizard( WindowsMessage Handler) -> WM_CONTEXTMENU->编辑之。

6.修改OnContextMenu函数

{CSDN:COED:27}

voidCRButtonMenuDlg::OnContextMenu(CWnd* pWnd, CPoint point)

{

       // TODO: Add your message handler codehere

       CMenu popMenu;

       popMenu.LoadMenu(IDR_RBTN_MENU);         //载入菜单

       CMenu *pPopup;

       pPopup=popMenu.GetSubMenu(0);     //获得子菜单指针

      

       pPopup->EnableMenuItem(ID_1,MF_BYCOMMAND|MF_ENABLED);  //允许菜单项使用

       pPopup->EnableMenuItem(ID_2,MF_BYCOMMAND|MF_DISABLED|MF_GRAYED);       //不允许菜单项使用

 

       //ClientToScreen(&point);            //将客户区坐标转换成屏幕坐标

       pPopup->TrackPopupMenu(TPM_LEFTALIGN|TPM_RIGHTBUTTON,point.x,point.y,this);                //显示弹出菜单，参数依次为(鼠标在菜单左边|跟踪右键，x，y，this)

       pPopup->Detach();

       popMenu.DestroyMenu();

}

2.添加菜单消息响应函数

1.在资源窗口插入菜单，编辑菜单。（菜单名称后面加(&字母)就是快捷键）

2.在对话框右键>属性>常规     菜单选框中选择上面建立的菜单。

运行可以见到，对话框已建立起了菜单，下面开始添加响应事件

菜单每一项都有一个ID，可以在菜单窗口查看。1.在对话框的CPP文件里的响应事件列表中BEGIN_MESSAGE_MAP 加上：     ON_COMMAND(ID_1, OnC1)         // 第一个参数为菜单项ID,第二个参数为事件名称，这里命名为OnC1;

2.在对话框的类中(.h文件)添加成员函数声明：  afx_msg void OnC1();  

3.在对话框的CPP文件中加成员函数（菜单响应事件）的定义void CMyDlg::OnC1(){       MessageBox("Test ok");}

3.菜单消息响应里使用剪切板实现复制，粘贴功能。

下面的代码示范了如何将文本内容复制到剪贴板：

C++代码:

Cstring source;//文本内容保存在source变量中if(openClipboard()){HGLOBAL clipbuffer;char * buffer;EmptyClipboard();clipbuffer = GlobalAlloc(GMEM_DDESHARE, dource.GetLength()+1);buffer = (char*)GlobalLock(clipbuffer);Strcpy(buffer, LPCSTR(source));GlobalUnlock(clipbuffer);SetClipboardData(CF_TEXT,clipbuffer);CloseClipboard();}

下面的代码显示了如何从剪贴板上获得文本内容：

C++代码:

char * buffer = NULL;//打开剪贴板CString fromClipboard;if ( OpenClipboard() ){HANDLE hData = GetClipboardData(CF_TEXT);char * buffer = (char*)GlobalLock(hData);fromClipboard = buffer;GlobalUnlock(hData);CloseClipboard();}
