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 }
