Win32建立右键弹出菜单(PopMenu)

自定义右键菜单:

 #ifndef  _CONTEXTMENU_H_
 #define _CONTEXTMENU_H_
 #include <windows.h>

 //动态菜单
 #define  ITEM_MENU_REPLY  40001
 #define  ITEM_MENU_ALLREPLAY 40002
 #define  ITEM_MENU_RELAY 40003
 #define  ITEM_MENU_DELETE 40004
 #define  ITEM_MENU_FINALDELETE 40005
 #define  ITEM_MEUN_MARK 40006
 #define  ITEM_SUBMENU_UNSEEN 40007
 #define ITEM_SUBMENU_SEEN 40008

 class CContextPopMenu
 {
 public:
     CContextPopMenu();
     ~CContextPopMenu();

     void PopMenu(HWND hwnd,int nX,int nY );
     void PopMenu(HWND hwnd,const POINT& pt);

     void EnableMenu(int nItem,bool nEnable);
 private:
     HMENU m_pPopMenu;
 };
 #endif

 #include "ContextMenu.h"

 CContextPopMenu::CContextPopMenu()
 {
     m_pPopMenu = CreatePopupMenu();
     if (m_pPopMenu)
     {
         HMENU Submenu = ::CreatePopupMenu();
         ::InsertMenu(m_pPopMenu,(-),MF_BYPOSITION,ITEM_MENU_REPLY,TEXT("回复"));
         ::InsertMenu(m_pPopMenu,(-),MF_BYPOSITION,ITEM_MENU_ALLREPLAY,TEXT("全部回复"));
         ::InsertMenu(m_pPopMenu,(-),MF_BYPOSITION,ITEM_MENU_RELAY,TEXT("转发"));
         ::InsertMenu(m_pPopMenu,(-),MF_BYPOSITION,ITEM_MENU_DELETE,TEXT("删除"));
         ::InsertMenu(m_pPopMenu,(-),MF_BYPOSITION,ITEM_MENU_FINALDELETE,TEXT("彻底删除"));
         ::InsertMenu(m_pPopMenu,(-),MF_BYPOSITION|MF_POPUP,(unsigned int)Submenu,TEXT("标记"));
         ::InsertMenu(Submenu,(-),MF_BYPOSITION|MF_POPUP,ITEM_SUBMENU_UNSEEN,TEXT("未读邮件"));
         ::InsertMenu(Submenu,(-),MF_BYPOSITION|MF_POPUP,ITEM_SUBMENU_SEEN,TEXT("已读邮件"));
     }
 }

 CContextPopMenu::~CContextPopMenu()
 {
     if (m_pPopMenu)
     {
         DestroyMenu(m_pPopMenu);
         m_pPopMenu = NULL;
     }
 }

 void CContextPopMenu::PopMenu(HWND hwnd,int nX,int nY )
 {
     if (m_pPopMenu && hwnd)
     {
         TrackPopupMenu(m_pPopMenu,TPM_LEFTALIGN|TPM_RIGHTBUTTON,nX,nY,,hwnd,NULL)
     }
 }

 void CContextPopMenu::PopMenu(HWND hwnd,const POINT& pt)
 {
     PopMenu(hwnd,pt.x,pt.y);
 }

然后在WndProc回调函数,响应WM_RBUTTONUP函数时创建

 case WM_RBUTTONUP:
     POINT pt;
     ::GetCursorPos(&pt);
     CContextPopMenu* pPopMenu = new CContextPopMenu;
     pPopMenu->PopMenu(hwnd,pt);
 break;

对每个菜单项的响应在WM_COMMAND消息里处理

 case WM_COMMAND:
         switch(LOWORD(wParam))
         {
         case ITEM_MENU_REPLY:
             MessageBox(NULL,TEXT("响应回复菜单项"),TEXT("提示"),MB_OK);
             break;;
         case ITEM_SUBMENU_UNSEEN:
             MessageBox(NULL,TEXT("响应标记子菜单项"),TEXT("提示"),MB_OK);
             break;
         }
