1、实验五 菜单工具栏状态栏程序设计实验五 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 here CClientDC dc(this); dc.TextOut(20,20,我已经学会了如何设计菜单程序!); void CSDIDispView:On
2、Picture() / TODO: Add your command handler code here CClientDC 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”
3、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 here CClientDC 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 here CClientDC dc(this); CBrush *BrushOld,BrushNew; Bru
4、shNew.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 here pCmdUI-Enable(
5、m_text);void CSDIDispView:OnUpdatePicture(CCmdUI* pCmdUI) / TODO: Add your command update UI handler code here pCmdUI-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 here MessageBox(我已经学会了使用默认工
6、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 default
7、 CString 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
8、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.LoadT
9、oolBar(IDR_TOOLBAR1) TRACE0(Failed to create toolbarn); return -1; / fail to create m_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
10、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 default CTime 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.Comm
11、andToIndex(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 default KillTimer(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 hand
12、ler code here time=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 here time=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 CClie
13、ntDC dc(this); dc.TextOut(100,100,现在是+str+时); void CSTimeView:OnMinute() / TODO: Add your command handler code here time=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 CSTimeVie
14、w:OnContextMenu(CWnd*, CPoint point) / CG: This block was added by the Pop-up Menu component if (point.x = -1 & point.y = -1) /keystroke invocation CRect rect; GetClientRect(rect); ClientToScreen(rect); point = rect.TopLeft(); point.Offset(5, 5); CMenu menu; VERIFY(menu.LoadMenu(CG_IDR_POPUP_STIME_V
15、IEW); 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
16、）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 toolb
17、arn); return -1; / fail to create / TODO: Delete these three lines if you dont want the toolbar to / be dockable m_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
