VS MFC 添加右键快捷菜单 Pop-up Menu

一.在ResourceView选项卡的Menu下添加一个菜单资源

二.在View的属性->消息->添加WM_CONTEXTMENU

三.在View里添加如下代码：
 1 void CTestView::OnContextMenu(CWnd* /*pWnd*/, CPoint point)

 2 {

 3     // TODO: 在此处添加消息处理程序代码

 4     //if (point.x == -1 && point.y == -1){

 5     //    CRect rect;

 6     //    GetClientRect(rect);

 7     //    ClientToScreen(rect);

 8     //    point = rect.TopLeft();

 9     //    point.Offset(5, 5);

10     // }

11     // CMenu menu;

12     // VERIFY(menu.LoadMenu(IDR_MENU1));        //CG_IDR_POPUP_TYPING_TEST_VIEW为菜单ID

13     // CMenu* pPopup = menu.GetSubMenu(0);

14     // ASSERT(pPopup != NULL);

15     // CWnd* pWndPopupOwner = this;

16     // while (pWndPopupOwner->GetStyle() & WS_CHILD)  pWndPopupOwner = pWndPopupOwner->GetParent();

17     // pPopup->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, point.x, point.y,pWndPopupOwner);

18 

19     if (point.x == -1 && point.y == -1){

20         //keystroke invocation

21         CRect rect;

22         GetClientRect(rect);

23         ClientToScreen(rect);　　//把客户区坐标转换为屏幕坐标

24 

25         point = rect.TopLeft();

26         point.Offset(5, 5);

27     }

28 

29     CMenu menu;

30     VERIFY(menu.LoadMenu(IDR_MENU1));    //IDR_MENU1为右键菜单ID

31 

32     CMenu* pPopup = menu.GetSubMenu(0);

33     ASSERT(pPopup != NULL);

34     CWnd* pWndPopupOwner = this;

35 

36     while (pWndPopupOwner->GetStyle() & WS_CHILD)

37         pWndPopupOwner = pWndPopupOwner->GetParent();

38 

39     pPopup->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, point.x, point.y,

40         pWndPopupOwner);　　//显示一个快捷菜单

41 }
