동적으로 팝업 메뉴 생성

MFC 일 경우 OnContextMenu에서 아래와 같이 생성한다.

void    CCustomCtrl::OnContextMenu(CWnd * pWnd, CPoint point) {         CMenu Menu;         if( Menu.CreatePopupMenu() == TRUE)         {                for(i=0; i<(UINT)m_StringArrary.GetCount(); i++)                {                        Menu.AppendMenu(MF_STRING | MF_ENABLED, POPUPID_RANGE_START + i, m_StringArrary.GetAt(i));                }                  Menu.AppendMenu(MF_SEPARATOR, 0, "");                Menu.AppendMenu(MF_STRING | MF_ENABLED, POPUPID_ENABLELOG, POPUPSTR_ENABLELOG);                Menu.AppendMenu(MF_STRING | MF_ENABLED, POPUPID_DIABLELOG, POPUPSTR_DISABLELOG);                Menu.AppendMenu(MF_STRING | MF_ENABLED, POPUPID_RESET, POPUPSTR_RESET);                Menu.AppendMenu(MF_STRING | MF_ENABLED, POPUPID_ACTIVEUIID, POPUPSTR_ACTIVEUIID);                  Menu.TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, point.x, point.y, this);         }       }

그리고 위 메시지를 처리하기 위해 메시지 맵에다가 아래와 같이 선언한다.

BEGIN_MESSAGE_MAP(CCustomCtrl, COleControl)         ON_COMMAND_RANGE(POPUPID_RANGE_START, POPUPID_RANGE_END, OnCommandRange)         ON_COMMAND(POPUPID_DIABLELOG, OnDisableLog)         ON_COMMAND(POPUPID_ENABLELOG, OnEnableLog)         ON_COMMAND(POPUPID_RESET, OnResetCommand)         ON_COMMAND(POPUPID_ACTIVEUIID, OnGetActiveUIIDCommand) END_MESSAGE_MAP()

ON_COMMAND_RANGE 의 경우는 아래와 같이 처리한다.

void CCusomCtrl::OnCommandRange(UINT uiCommandID) {         switch(uiCommandID) { }; }

참고로 BCG에서는 아래와 같이 처리한다.

void CQueryBuilderGridCtrl::OnContextMenu(CWnd* pWnd, CPoint point) {         CMenu contextMenu;         if(contextMenu.CreatePopupMenu() == TRUE)         {                contextMenu.AppendMenu(MF_STRING | MF_ENABLED, QBGC_ID_SEARCH, _T("&Search") );                contextMenu.AppendMenu(MF_SEPARATOR, 0, "");                contextMenu.AppendMenu(MF_STRING | MF_ENABLED, QBGC_ID_INSERT, _T("&Insert") );                contextMenu.AppendMenu(MF_STRING | MF_ENABLED, QBGC_ID_DELETE, _T("&Delete") );                contextMenu.AppendMenu(MF_STRING | MF_ENABLED, QBGC_ID_GROUP, _T("&Group") );                contextMenu.AppendMenu(MF_STRING | MF_ENABLED, QBGC_ID_UNGROUP, _T("&Ungroup") );                    CBCGPPopupMenu * pPopupMenu = new CBCGPPopupMenu;                if (!pPopupMenu->Create(this, point.x, point.y, contextMenu.GetSafeHmenu(), FALSE, TRUE))                {                        return;                }                  ((CBCGPFrameWnd*)AfxGetMainWnd())->OnShowPopupMenu (pPopupMenu);         } }

만약 좌표가 정확치 않은 경우 ClientToScreen 또는 ScreenToClient를 활용한다.
