这节课的主要内容是讲菜单，分为静态菜单和动态菜单
动态：
CMainFrame::OnCreate
1 int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct) 2 { 3 if (CFrameWnd::OnCreate(lpCreateStruct) == -1) 4 return -1; 5 6 if (!m_wndToolBar.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP 7 | CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC) || 8 !m_wndToolBar.LoadToolBar(IDR_MAINFRAME)) 9 {10 TRACE0("未能创建工具栏\n");11 return -1; // 未能创建12 }13 14 if (!m_wndStatusBar.Create(this) ||15 !m_wndStatusBar.SetIndicators(indicators,16 sizeof(indicators)/sizeof(UINT)))17 {18 TRACE0("未能创建状态栏\n");19 return -1; // 未能创建20 }21 22 // TODO: 如果不需要可停靠工具栏，则删除这三行23 m_wndToolBar.EnableDocking(CBRS_ALIGN_ANY);24 EnableDocking(CBRS_ALIGN_ANY);25 DockControlBar(&m_wndToolBar);26 27 /*CMenu menu;28 menu.CreatePopupMenu();29 // GetMenu()->AppendMenuA(MF_POPUP, (UINT)menu.m_hMenu, "Panda");30 GetMenu()->InsertMenuA(2, MF_BYPOSITION | MF_POPUP, (UINT)menu.m_hMenu, "Panda");31 menu.AppendMenuA(MF_STRING, IDM_HELLO, "Hello");32 menu.AppendMenuA(MF_STRING, 112, "Panda");33 menu.AppendMenuA(MF_STRING, 113, "Mybole");34 /* GetMenu()->GetSubMenu(0)->AppendMenuA(MF_STRING, 114, "welcome");35 GetMenu()->GetSubMenu(0)->InsertMenuA(ID_FILE_OPEN, MF_BYCOMMAND | MF_STRING, 115, "熊猫");36 GetMenu()->DeleteMenu(1, MF_BYPOSITION);37 GetMenu()->GetSubMenu(0)->DeleteMenu(2, MF_BYPOSITION);*/38 39 /*menu.Detach();*/40 41 return 0;42 }
