实验五 菜单、工具栏、状态栏程序设计【实验目的】1、 掌握主菜单程序设计方法2、 学会工具栏程序设计3、 掌握快捷菜单程序设计方法4、 学会增加状态栏窗格【实验内容】1、 建立一个单文档应用程序，添加菜单显示，其中包含“文本”和“图形”2个菜单项，分别输出文本和图形。参考代码：void CSDIDispView:OnText() / TODO: Add your command handler code hereCClientDC dc(this);dc.TextOut(20,20,我已经学会了如何设计菜单程序!);void CSDIDispView:OnPicture() / TODO: Add your command handler code hereCClientDC dc(this);CBrush *BrushOld,BrushNew;BrushNew.CreateSolidBrush(RGB(255,0,0); BrushOld=dc.SelectObject(&BrushNew); /选用画刷dc.Rectangle(50,50,250,150); dc.SelectObject(BrushOld); /还原画刷BrushNew.DeleteObject(); /释放画刷2、 为上述应用程序添加菜单控制功能，选中“文本”时，“图形”菜单项无效；当选中“图形”时，“文本”菜单项无效。参考代码：void CSDIDispView:OnText() / TODO: Add your command handler code hereCClientDC dc(this);dc.TextOut(20,20,我已经学会了如何设计菜单程序!);m_picture=false;void CSDIDispView:OnPicture() / TODO: Add your command handler code hereCClientDC dc(this);CBrush *BrushOld,BrushNew;BrushNew.CreateSolidBrush(RGB(255,0,0); BrushOld=dc.SelectObject(&BrushNew); /选用画刷dc.Rectangle(50,50,250,150); dc.SelectObject(BrushOld); /还原画刷BrushNew.DeleteObject(); /释放画刷m_text=false;void CSDIDispView:OnUpdateText(CCmdUI* pCmdUI) / TODO: Add your command update UI handler code herepCmdUI-Enable(m_text);void CSDIDispView:OnUpdatePicture(CCmdUI* pCmdUI) / TODO: Add your command update UI handler code herepCmdUI-Enable(m_picture);3、为上述应用程序工具栏添加两个工具按钮，单击第一个按钮，在视图窗口中弹出“打开文件”对话框，单击第二个按钮，在消息框中显示文本信息。参考代码：void CXiTi4_3View:OnText() / TODO: Add your command handler code hereMessageBox(我已经学会了使用默认工具栏了！);4、创建一个单文档应用程序，在状态栏中显示鼠标光标的坐标。(1)在MainFrm.h中将状态栏对象修改为publicpublic:CStatusBar m_wndStatusBar;(2)在MainFrm.cpp中添加状态栏窗格ID_INDICATOR_COR(3)在串表中设置添加窗格的字符串格式(4)添加WM_MOUSEMOVE消息及其相应函数void CXiTi4_4View:OnMouseMove(UINT nFlags, CPoint point) / TODO: Add your message handler code here and/or call defaultCString str;CMainFrame *pFrame=(CMainFrame*)AfxGetApp()-m_pMainWnd; CStatusBar *pStatus=&pFrame-m_wndStatusBar;str.Format(%d,%d,point.x,point.y);pStatus-SetPaneText(pStatus-CommandToIndex(ID_INDICATOR_COR),str);CView:OnMouseMove(nFlags, point);5、 建立一个单文档应用程序，添加“时间”主菜单项，包含时、分、秒三个菜单项，分别在视图窗口中显示当前系统时间的时、分和秒。添加相应的工具栏和快捷菜单，并在状态栏中显示系统时间。(1)添加菜单项、添加工具栏插入工具栏并编辑，添加工具栏类定义工具栏对象：CToolBar m_wndToolBar, m_wndToolBar1;加载工具栏：OnCreate( ):if (!m_wndToolBar1.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP| CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC) |!m_wndToolBar1.LoadToolBar(IDR_TOOLBAR1)TRACE0(Failed to create toolbarn);return -1; / fail to createm_wndToolBar.EnableDocking(CBRS_ALIGN_ANY);m_wndToolBar1.EnableDocking(CBRS_ALIGN_ANY);EnableDocking(CBRS_ALIGN_ANY);DockControlBar(&m_wndToolBar);DockControlBar(&m_wndToolBar1);设置时钟：SetTimer(1,1000,NULL);(2)添加状态栏添加状态栏窗格：ID_INDICATOR_TIME,设置字符串格式状态栏数据成员设置为公有成员void CMainFrame:OnTimer(UINT nIDEvent) / TODO: Add your message handler code here and/or call defaultCTime time;time=CTime:GetCurrentTime();/获得系统时间CString str=time.Format(%H:%M:%S);/将系统时间转换成时:分:秒格式的字符串m_wndStatusBar.SetPaneText(m_wndStatusBar.CommandToIndex(ID_INDICATOR_TIME),str);/更新时间窗格显示的时间内容CFrameWnd:OnTimer(nIDEvent);void CMainFrame:OnClose() / TODO: Add your message handler code here and/or call defaultKillTimer(1);/关闭计时器CFrameWnd:OnClose();(3)添加菜单消息响应定义CTime类的对象time添加菜单消息响应函数：void CSTimeView:OnSecond() / TODO: Add your command handler code heretime=CTime:GetCurrentTime();/获得系统时间CString str=time.Format(%S);/将系统时间转换成秒格式的字符串CClientDC dc(this);dc.TextOut(100,100,现在是+str+秒); void CSTimeView:OnHour() / TODO: Add your command handler code heretime=CTime:GetCurrentTime();/获得系统时间CString str=time.Format(%H);/将系统时间转换成时格式的字符串CClientDC dc(this);dc.TextOut(100,100,现在是+str+时); void CSTimeView:OnMinute() / TODO: Add your command handler code heretime=CTime:GetCurrentTime();/获得系统时间CString str=time.Format(%M);/将系统时间转换成分格式的字符串CClientDC dc(this);dc.TextOut(100,100,现在是+str+分); (4)添加快捷菜单设计快捷菜单添加WM_ContextMenu消息响应函数：void CSTimeView:OnContextMenu(CWnd*, CPoint point)/ CG: This block was added by the Pop-up Menu componentif (point.x = -1 & point.y = -1)/keystroke invocationCRect rect;GetClientRect(rect);ClientToScreen(rect);point = rect.TopLeft();point.Offset(5, 5);CMenu menu;VERIFY(menu.LoadMenu(CG_IDR_POPUP_STIME_VIEW);CMenu* pPopup = menu.GetSubMenu(0);ASSERT(pPopup != NULL);CWnd* pWndPopupOwner = this;while (pWndPopupOwner-GetStyle() & WS_CHILD)pWndPopupOwner = pWndPopupOwner-GetParent();pPopup-TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, point.x, point.y,pWndPopupOwner);6、 绘制正弦和余弦曲线，设置线型和颜色的变换。1）添加菜单添加工具栏资源添加快捷菜单资源2）加载工具栏：Mainfrm.h:CToolBar m_wndToolBar1;Mainfrm.cpp:Oncreate:if (!m_wndToolBar1.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP| CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC) |!m_wndToolBar1.LoadToolBar(IDR_TOOLBAR1)TRACE0(Failed to create toolbarn);return -1; / fail to create/ TODO: Delete these three lines if you dont want the toolbar to/ be dockablem_wndToolBar.EnableDocking(CBRS_ALIGN_ANY);m_wndToolBar1.EnableDocking(CBRS_ALIGN_ANY);EnableDocking(CBRS_ALIGN_ANY);DockControlBar(&m_wndToolBar);DockControlBar(&m_wndToolBar1);3）加载快捷菜单：添加视图类得wm_context消息void CP1View:OnContextMenu(CWnd* pWnd, CPoint point) / TODO: Add your message handler code hereCMenu menu,*pPopup;menu.LoadMenu(IDR_MENU1);/加载快捷菜单pPopup = menu.GetSubMenu(0);CWnd* pWndPopupOwner = this;pWndPopupOwner = pWndPopupOwner-GetParent();/显示快捷菜单pPopup-TrackPopupMenu(TPM_LEFTALIGN|TPM_RIGHTBUTTON,point.x,point.y,pWndPopupOwner);4）添加视图类的成员变量及成员函数Cview.hconst double PI=3.1416;public: int m_able;int m_typ; int m_wid;COLORREF m_col;double calsin(int x);double calcos(int x);void drawcurve(CDC* pDC);void drawline(CDC* pDC, int x1,int y1,int x2,int y2);void drawaxis(CDC* pDC);Cview.cppCCurveView:CCurveView()/ TODO: add construction code herem_typ=0;m_col=RGB(0,0,0);m_wid=1;m_able=0;void CCurveView:OnDraw(CDC* pDC)CCurveDoc* pDoc = GetDocument();ASSERT_VALID(pDoc);/ TODO: add draw code for native data heredrawcurve(pDC);double CCurveView:calsin(int x)double y;
