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,(-1),MF_BYPOSITION,ITEM_MENU_REPLY,TEXT("回复"));
        ::InsertMenu(m_pPopMenu,(-1),MF_BYPOSITION,ITEM_MENU_ALLREPLAY,TEXT("全部回复"));
        ::InsertMenu(m_pPopMenu,(-1),MF_BYPOSITION,ITEM_MENU_RELAY,TEXT("转发"));
        ::InsertMenu(m_pPopMenu,(-1),MF_BYPOSITION,ITEM_MENU_DELETE,TEXT("删除"));
        ::InsertMenu(m_pPopMenu,(-1),MF_BYPOSITION,ITEM_MENU_FINALDELETE,TEXT("彻底删除"));
        ::InsertMenu(m_pPopMenu,(-1),MF_BYPOSITION|MF_POPUP,(unsigned int)Submenu,TEXT("标记"));
        ::InsertMenu(Submenu,(-1),MF_BYPOSITION|MF_POPUP,ITEM_SUBMENU_UNSEEN,TEXT("未读邮件"));
        ::InsertMenu(Submenu,(-1),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,0,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;
        }
