孙鑫第9课--修改应用程序外观(工具栏、状态栏).doc

新建一个工程，MFC单文档，名字为Test，单文档。改变应用程序外观，应该在窗口创建之前修改。改变框架窗口的大小和外观，在BOOL CMainFrame:PreCreateWindow(CREATESTRUCT& cs)中修改。下面的程序是在窗口创建之前修改：BOOL CMainFrame:PreCreateWindow(CREATESTRUCT& cs)if( !CFrameWnd:PreCreateWindow(cs) )return FALSE;/ TODO: Modify the Window class or styles here by modifying/ the CREATESTRUCT cscs.cx=200;cs.cy=300;cs.style &= FWS_ADDTOTITLE;/cs.style = WS_OVERLAPPED | WS_SYSMENU | WS_BORDER;/或者这样也可以。cs.lpszName=标题;/将文档标题改为自己的标题，因为系统的SDI的style=WS_OVERLAPPEDWINDOW and FWS_ADDTOTITLE return TRUE;下面的代码是在窗口创建之后修改：在int CMainFrame:OnCreate(LPCREATESTRUCT lpCreateStruct)中添加：SetWindowLong(m_hWnd,GWL_STYLE,GetWindowLong(m_hWnd,GWL_STYLE)&WS_MAXIMIZEBOX );/没有了最大化框。修改窗口的图标，光标，背景。在BOOL CMainFrame:PreCreateWindow(CREATESTRUCT& cs)中添加：BOOL CMainFrame:PreCreateWindow(CREATESTRUCT& cs)if( !CFrameWnd:PreCreateWindow(cs) )return FALSE;/ TODO: Modify the Window class or styles here by modifying/ the CREATESTRUCT cs WNDCLASS wdcls;wdcls.cbClsExtra=0;wdcls.cbWndExtra=0;wdcls.hbrBackground=(HBRUSH)GetStockObject(BLACK_BRUSH);wdcls.hCursor=LoadCursor(NULL,IDC_HELP);wdcls.hIcon=LoadIcon(NULL,IDI_ERROR);wdcls.hInstance=AfxGetInstanceHandle( );wdcls.lpfnWndProc=:DefWindowProc;wdcls.lpszClassName=newclass;wdcls.lpszMenuName=NULL;/不会影响菜单的创建wdcls.style=CS_HREDRAW|CS_VREDRAW;RegisterClass(&wdcls);cs.lpszClass=newclass;return TRUE;运行结果，仅ICON改变。背景和光标没有改变。（它们是VIEW类的，不是框架类的，要改变应该在VIEW类中）；下面代码：BOOL CTestView:PreCreateWindow(CREATESTRUCT& cs)/ TODO: Modify the Window class or styles here by modifying/ the CREATESTRUCT cs cs.lpszClass=newclass;return CView:PreCreateWindow(cs);在框架类中只能修改图标，下面是另一种方法：BOOL CMainFrame:PreCreateWindow(CREATESTRUCT& cs)if( !CFrameWnd:PreCreateWindow(cs) )return FALSE;/ TODO: Modify the Window class or styles here by modifyingcs.lpszClass=AfxRegisterWndClass(CS_VREDRAW | CS_HREDRAW,0,0,:LoadIcon(NULL, IDI_APPLICATION);return TRUE;在VIEW类中修改光标，背景色。BOOL CTestView:PreCreateWindow(CREATESTRUCT& cs)/ TODO: Modify the Window class or styles here by modifying/ the CREATESTRUCT cs cs.lpszClass=AfxRegisterWndClass(CS_VREDRAW | CS_HREDRAW,:LoadCursor(NULL, IDC_HELP),(HBRUSH) :GetStockObject(BLACK_BRUSH),0);return CView:PreCreateWindow(cs);在窗口创建之后，修改也可以用下面的方法：在int CMainFrame:OnCreate(LPCREATESTRUCT lpCreateStruct)中添加：SetClassLong(m_hWnd,GCL_HICON,(LONG)LoadIcon(NULL,IDI_ERROR);在int CTestView:OnCreate(LPCREATESTRUCT lpCreateStruct) if (CView:OnCreate(lpCreateStruct) = -1)return -1;/ TODO: Add your specialized creation code hereSetClassLong(m_hWnd,GCL_HBRBACKGROUND,(LONG)GetStockObject(BLACK_BRUSH);return 0;下面完成一个不断变化的图标：创建三个ICON。为框架类添加：private:HICON m_hicon3;准备三幅图标：在int CMainFrame:OnCreate(LPCREATESTRUCT lpCreateStruct)前添加：extern CTestApp theApp;在int CMainFrame:OnCreate(LPCREATESTRUCT lpCreateStruct)中添加： m_hicon0=LoadIcon(AfxGetInstanceHandle(),MAKEINTRESOURCE(IDI_ICON1);m_hicon1=LoadIcon(AfxGetApp( )-m_hInstance,MAKEINTRESOURCE(IDI_ICON2);m_hicon2=LoadIcon(theApp.m_hInstance,MAKEINTRESOURCE(IDI_ICON3);SetTimer(1,1000,NULL);void CMainFrame:OnTimer(UINT nIDEvent) / TODO: Add your message handler code here and/or call defaultstatic int i=0;SetClassLong(m_hWnd,GCL_HICON,(LONG)m_hicon0);SetClassLong(m_hWnd,GCL_HICON,(LONG)m_hicon+i%3);CFrameWnd:OnTimer(nIDEvent);下面是工具栏的编程：为框架栏增加：CToolBar m_newToolBar;在资源中增加一个新的工具栏。在int CMainFrame:OnCreate(LPCREATESTRUCT lpCreateStruct)中添加下列代码：if (!m_newToolBar.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP| CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC) |!m_newToolBar.LoadToolBar(IDR_TOOLBAR1)TRACE0(Failed to create toolbarn);return -1; / fail to createm_newToolBar.EnableDocking(CBRS_ALIGN_ANY);EnableDocking(CBRS_ALIGN_ANY);DockControlBar(&m_newToolBar);添加一个显示新工具栏的菜单项。并加上标记。void CMainFrame:OnNewToolbar() / TODO: Add your command handler code hereif (m_newToolBar.IsVisible()ShowControlBar( &m_newToolBar,FALSE,FALSE);/ ShowControlBar可以显示一个控件在原先的位置上。 else/m_newToolBar.ShowWindow(SW_SHOW);ShowControlBar( &m_newToolBar,TRUE,FALSE);或者：void CMainFrame:OnNewToolbar() / TODO: Add your command handler code hereCRect rect; /rect是用来存贮工具栏浮动时的位置的CFrameWnd* pParentFrame = m_newToolBar.GetDockingFrame();if(m_newToolBar.IsFloating() pParentFrame-GetWindowRect(&rect);/获取工具栏位置，并存贮在rect中if(m_newToolBar.IsWindowVisible()m_newToolBar.ShowWindow(SW_HIDE);elsem_newToolBar.ShowWindow(SW_SHOW);RecalcLayout();DockControlBar(&m_newToolBar);if(!rect.IsRectEmpty()FloatControlBar(&m_newToolBar,CPoint(rect.left,rect.top);/使工具栏浮动到/上面对比一下，就可以知道ShowControlBar的使用方便了。void CMainFrame:OnUpdateNewToolbar(CCmdUI* pCmdUI) / TODO: Add your command update UI handler code hereif (m_newToolBar.IsVisible()pCmdUI-SetCheck(1); elsepCmdUI-SetCheck(0);下面是状态栏的编程：在框架中：static UINT indicators =ID_SEPARATOR, / status line indicatorID_INDICATOR_CAPS,ID_INDICATOR_NUM,ID_INDICATOR_SCRL,ID_TIME,/show timeID_PROCESS/show process;在资源视图中的STRING中加入对ID_TIME和ID_PROCESS的说明；创建一个定时器，来显示时间。void CMainFrame:OnTimer(UINT nIDEvent) / TODO: Add your message handler code here and/or call defaultCString str;CTime t = CTime:GetCurrentTime();str=t.Format(%H:%M:%S);m_wndStatusBar.SetPaneText( 4, str);CFrameWnd:OnTimer(nIDEvent);在int CMainFrame:OnCreate(LPCREATESTRUCT lpCreateStruct)中添加：CString str;CTime t = CTime:GetCurrentTime();str=t.Format(%H:%M:%S);CClientDC dc(this);CSize size=dc.GetTextExtent(str) ;m_wndStatusBar.SetPaneInfo( 4, ID_TIME, SBPS_NORMAL, size.cx ); m_wndStatusBar.SetPaneText( 4, str);下面创建一个进度栏：为框架类增加：CProgressCtrl myCtrl;在int CMainFrame:OnCreate(LPCREATESTRUCT lpCreateStruct)CRect rect; m_wndStatusBar.GetItemRect( 5, &rect ); myCtrl.Create(WS_CHILD|WS_VISIBLE|PBS_SMOOTH, rect, &m_wndStatusBar, 1);/这样得到的rect是得不到的。因为在这时窗口在创建，是得不到窗口的区域大小的。myCtrl.SetPos(50); myCtrl.SetRange( 0, 100 );为此代码修改如下：在头文件中：#define UM_PROCRESS WM_USER+1（2：02）afx_msg void OnProgress();在。CPP中添加：ON_MESSAGE(UM_PROCRESS,OnProgress)在int CMainFrame:OnCreate(LPCREATESTRUCT lpCreateStruct)中添加：PostMessage(UM_PROCRESS);void CMainFrame:OnProgress()CRect rect; m_wndStatusBar.GetItemRect( 5, &rect ); myCtrl.Create(WS_CHILD|WS_VISIBLE/*|PBS_SMOOTH*/, rect, &m_wndStatusBar, 1);/这样得到的rect是得不到的。因为在这时窗口在创建，是得不到窗口的区域大小的。myCtrl.SetPos(50); myCtrl.SetRange( 0, 100 );上面的代码，当窗口变化的时候，进度栏会变化。下面是改进的代码：PostMessage(UM_PROCRESS);这句代码不要了。OnProgress()消息删除。void CMainFrame:OnPaint() CPaintDC dc(this); / device context for paintingCRect rect;m_wndStatusBar.GetItemRect( 5, &rect );if (!myCtrl.m_hWnd)myCtrl.Create(WS_CHILD|WS_VISIBLE/*|PBS_SMOOTH*/, rect, &m_wndStatusBar, 1);myCtrl.SetPos(50); myCtrl.SetRange( 0, 100 );elsemyCtrl.MoveWindow(rect);让进度栏动起来：在OnTimer中添加：myCtrl.SetStep(10);myCtrl.StepIt();下面将鼠标的坐标点在状态栏的第一个PANE显示出来。在框架中包含#i
