1、首先在xxxApp文件中的InitInstance() // 初始化窗体 INITCOMMONCONTROLSEX InitCtrls; InitCtrls.dwSize = sizeof(InitCtrls); InitCtrls.dwICC = ICC_WIN95_CLASSES; // 注册窗口 SetRegistryKey(_T("Local AppWizard-Generated Applications")); // 创建主窗口 CMainFrame* pFrame = new CMainFrame; if (!pFrame) return FALSE; CRect rect; ::SystemParametersInfo(SPI_GETWORKAREA, 0, &rect, 0); rect.left *= 0.8; rect.right *= 0.8; rect.top *= 0.9; rect.bottom *= 0.9; pFrame->CreateEx(0, _T("xxxx"), _T("xxxx"), WS_OVERLAPPEDWINDOW, rect, NULL, NULL); m_pMainWnd = pFrame; pFrame->ShowWindow(SW_SHOW); pFrame->CenterWindow(); pFrame->UpdateWindow(); pFrame->MaxSize(); pFrame->BringWindowToTop(); 2、在CMainFrame中添加PreCreateWindow 设置窗体属性 BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs) { if( !CAsbCtrlContainer::PreCreateWindow(cs) ) return FALSE; WNDCLASS wndcls; ZeroMemory(&wndcls, sizeof(wndcls)); wndcls.style = CS_DBLCLKS; wndcls.lpfnWndProc = ::DefWindowProc; wndcls.hInstance = AfxGetInstanceHandle(); wndcls.hCursor = AfxGetApp()->LoadStandardCursor(IDC_ARROW); wndcls.lpszClassName = cs.lpszClass; wndcls.hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME); wndcls.hbrBackground = 0; AfxRegisterClass(&wndcls); return TRUE; } 3、在OnCreate中设置窗口模式 ModifyStyle(WS_CAPTION, 0, SWP_FRAMECHANGED); 4、在OnSize中，创建其它控件之前要先判断窗体是否创建成功 if ( m_wndDeviceInfo.GetSafeHwnd() != NULL && m_wndTitleBar.GetSafeHwnd() != NULL && m_wndStatusBar.GetSafeHwnd() != NULL && m_wndMainView.GetSafeHwnd() !=NULL ) { CRect rcClient; GetClientRect(rcClient); if (rcClient.IsRectEmpty()) return; .................... .................... ｝ 完成这几步后就可以去掉系统标题栏，不管放大还是缩小，系统标题栏都不会出现 但是，会发现窗口外面有一层白色的框框，现在来去掉白色框框 5、在PreCreateWindow函数设置了一个窗口消息 wndcls.lpfnWndProc = ::DefWindowProc; 利用在这个消息可以去掉白色边框 在CMainFrame添加虚函数 virtual LRESULT DefWindowProc( UINT message, WPARAM wParam, LPARAM lParam ); LRESULT CMainFrame::DefWindowProc( UINT message, WPARAM wParam, LPARAM lParam ) { LRESULT lrst=CAsbCtrlContainer::DefWindowProc(message, wParam, lParam); if (!::IsWindow(m_hWnd)) return lrst; if (message==WM_MOVE||message==WM_PAINT||message==WM_NCPAINT||message==WM_NCACTIVATE ||message == WM_NOTIFY) { //如果已经最大化，则不再需要绘制边框，以免挡住了图标。 CRect rtWnd,rect; GetWindowRect(&rtWnd); ::SystemParametersInfo(SPI_GETWORKAREA, 0, &rect, 0); if (rtWnd.Height() == rect.Height()) { return lrst; } CDC* pWinDC = GetWindowDC(); if (pWinDC) DrawBorder(pWinDC); ReleaseDC(pWinDC); //InvalidateRect(NULL); } return lrst; } 6、然后在DrawBorder(pWinDC);中把边框用颜色填充 void CMainFrame::DrawBorder(CDC *pDC) { if (m_hWnd ) { CBrush Brush(RGB(0,0,0)); CBrush* pOldBrush = pDC->SelectObject(&Brush); CRect rtWnd; GetWindowRect(&rtWnd); CPoint point; //填充顶部框架 point.x = rtWnd.Width(); point.y = GetSystemMetrics(SM_CYFRAME); pDC->PatBlt(0, 0, point.x, point.y, PATCOPY); //填充左侧框架 point.x = GetSystemMetrics(SM_CXFRAME); point.y = rtWnd.Height(); pDC->PatBlt(0, 0, point.x, point.y, PATCOPY); //填充底部框架 point.x = rtWnd.Width(); point.y = GetSystemMetrics(SM_CYFRAME) ; pDC->PatBlt(0, rtWnd.Height()-point.y , point.x, point.y, PATCOPY); //填充右侧框架 point.x = GetSystemMetrics(SM_CXFRAME) ; point.y = rtWnd.Height(); pDC->PatBlt(rtWnd.Width()-point.x , 0, point.x, point.y, PATCOPY); pDC->SelectObject(pOldBrush); } } 可以完美实现去图标题栏 另外要在动态创建的标题栏上双击缩放窗口 1、首先要在标题栏添加鼠标点击和双击事件 void CTitleBarWnd::OnLButtonDown(UINT nFlags, CPoint point) { GetParent()->PostMessage(WM_TITLE_LBUTTONDOWN, point.x,point.y); CAsbCtrlContainer::OnLButtonDown(nFlags, point); } void CTitleBarWnd::OnLButtonDblClk(UINT nFlags, CPoint point) { GetParent()->PostMessage(WM_TITLE_LBUTTONDBLCLK, point.x,point.y); CAsbCtrlContainer::OnLButtonDblClk(nFlags, point); } 发送WM_TITLE_LBUTTONDOWN和WM_TITLE_LBUTTONDOWN消息到主程序窗口 2、在主程序窗口也要添加消息事件 // 双击标题栏 LRESULT CMainFrame::OnNcLButtonDblClk(WPARAM wParam, LPARAM lParam) { // if ( m_wndDeviceInfo.GetSafeHwnd() || m_wndMainView.GetSafeHwnd() ) // return 0; MaxSize(); return 0; } MaxSize()函数中缩放窗口大小 void CMainFrame::MaxSize() { static CRect s_rcCurrentMax(0,0,0,0); DWORD dwStyle = GetWindowLong(GetSafeHwnd(), GWL_STYLE); if (dwStyle & WS_THICKFRAME) { dwStyle &= ~WS_THICKFRAME; SetWindowLong(GetSafeHwnd(), GWL_STYLE, dwStyle); GetWindowRect(s_rcCurrentMax); //int nScreenW = GetSystemMetrics(SM_CXSCREEN); //int nScreenH = GetSystemMetrics(SM_CYSCREEN); CRect rect; ::SystemParametersInfo(SPI_GETWORKAREA, 0, &rect, 0); MoveWindow(rect); Relayout(); //m_wndTitleBar.UpdateMaxbtnImage(TRUE); m_wndTitleBar.Invalidate(); m_wndTitleBar.UpdateFullScreenBtnStatus( TRUE ); } else { dwStyle |= WS_THICKFRAME; SetWindowLong(GetSafeHwnd(), GWL_STYLE, dwStyle); MoveWindow(s_rcCurrentMax); Relayout(); //m_wndTitleBar.UpdateMaxbtnImage(FALSE); m_wndTitleBar.Invalidate(); m_wndTitleBar.UpdateFullScreenBtnStatus( FALSE ); } } // 单击标题栏 LRESULT CMainFrame::OnNcLButtonDown(WPARAM wParam, LPARAM lParam) { // if ( m_wndDeviceInfo.GetSafeHwnd() || m_wndMainView.GetSafeHwnd() ) // return 0; DWORD dwStyle = GetWindowLong(GetSafeHwnd(), GWL_STYLE); if (dwStyle & WS_THICKFRAME) // 没有最大化时才能拖动标题栏 { CPoint point; point.x = wParam; point.y = lParam; PostMessage(WM_NCLBUTTONDOWN, HTCAPTION, MAKELPARAM(point.x,point.y)); } return 0; } WM_NCLBUTTONDOWN消息使鼠标点击标题栏时能拖动窗口
