有关的信息可以参考 例子，下面是例子截图：

MSDN上的例子为：

BOOL  CMainFrame:: OnShowMDITabContextMenu( CPoint point,  DWORD  dwAllowedItems,  BOOL  bDrop) 
{ 
    CMenu menu; 
    VERIFY( menu.LoadMenu( bDrop ? IDR_POPUP_DROP_MDITABS :  IDR_POPUP_MDITABS)); 

    CMenu*  pPopup =  menu.GetSubMenu( 0 ); 
    ASSERT( pPopup !=  NULL ); 

    if  (( dwAllowedItems &  AFX_MDI_CREATE_HORZ_GROUP)  ==  0 )
    { 
        pPopup-> DeleteMenu( ID_MDI_NEW_HORZ_TAB_GROUP,  MF_BYCOMMAND); 
    } 

    if  (( dwAllowedItems &  AFX_MDI_CREATE_VERT_GROUP)  ==  0 )
    { 
        pPopup-> DeleteMenu( ID_MDI_NEW_VERT_GROUP,  MF_BYCOMMAND); 
    } 

    if  (( dwAllowedItems &  AFX_MDI_CAN_MOVE_NEXT)  ==  0 )
    { 
        pPopup-> DeleteMenu( ID_MDI_MOVE_TO_NEXT_GROUP,  MF_BYCOMMAND); 
    } 

    if  (( dwAllowedItems &  AFX_MDI_CAN_MOVE_PREV)  ==  0 )
    { 
        pPopup-> DeleteMenu( ID_MDI_MOVE_TO_PREV_GROUP,  MF_BYCOMMAND); 
    } 

    if  (( dwAllowedItems &  AFX_MDI_CAN_BE_DOCKED)  ==  0 )
    { 
        pPopup-> DeleteMenu( ID_MDI_TABBED_DOCUMENT,  MF_BYCOMMAND); 
    } 

    CMFCPopupMenu*  pPopupMenu =  new  CMFCPopupMenu; 
    pPopupMenu-> SetAutoDestroy( FALSE ); 
    pPopupMenu-> Create( this ,  point.x,  point.y,  pPopup-> GetSafeHmenu()); 

    return  TRUE ; 
} 

然后在在MainFrm.h中，添加声明virtual BOOL OnShowMDITabContextMenu(CPoint point, DWORD dwAllowedItems, BOOL bDrop);即可。
