MFC中非MDI子框架窗口

框架窗口也可以做为界面中的子窗口, 创建时要加入WM_CHILD属性.下面为示例

 

 

1. 主框架窗口

 

 #include "MyChildFrm.h" class CMainFrame : public CFrameWnd { public: CMainFrame(); protected: DECLARE_DYNAMIC(CMainFrame) // Attributes public: // Operations public: // Overrides // ClassWizard generated virtual function overrides //{{AFX_VIRTUAL(CMainFrame) virtual BOOL PreCreateWindow(CREATESTRUCT& cs); virtual BOOL OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo); //}}AFX_VIRTUAL // Implementation public: virtual ~CMainFrame(); #ifdef _DEBUG virtual void AssertValid() const; virtual void Dump(CDumpContext& dc) const; #endif protected: // control bar embedded members CStatusBar m_wndStatusBar; CToolBar m_wndToolBar; CMyChildFrm* m_pwndChildFrm; // Generated message map functions protected: //{{AFX_MSG(CMainFrame) afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct); afx_msg void OnSetFocus(CWnd *pOldWnd); // NOTE - the ClassWizard will add and remove member functions here. // DO NOT EDIT what you see in these blocks of generated code! //}}AFX_MSG DECLARE_MESSAGE_MAP() };

 

 

 int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct) { if (CFrameWnd::OnCreate(lpCreateStruct) == -1) return -1; m_pwndChildFrm = new CMyChildFrm; if (!m_pwndChildFrm->CWnd::Create(NULL, NULL, WS_VISIBLE | WS_CHILD, CRect(0,0,0,0), this, AFX_IDW_PANE_FIRST, NULL)) { TRACE0("Failed to create view window/n"); return -1; } if (!m_wndToolBar.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP | CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC) || !m_wndToolBar.LoadToolBar(IDR_MAINFRAME)) { TRACE0("Failed to create toolbar/n"); return -1; // fail to create } if (!m_wndStatusBar.Create(this) || !m_wndStatusBar.SetIndicators(indicators, sizeof(indicators)/sizeof(UINT))) { TRACE0("Failed to create status bar/n"); return -1; // fail to create } // TODO: Delete these three lines if you don't want the toolbar to // be dockable m_wndToolBar.EnableDocking(CBRS_ALIGN_ANY); EnableDocking(CBRS_ALIGN_ANY); DockControlBar(&m_wndToolBar); return 0; } BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs) { if( !CFrameWnd::PreCreateWindow(cs) ) return FALSE; // TODO: Modify the Window class or styles here by modifying // the CREATESTRUCT cs cs.dwExStyle &= ~WS_EX_CLIENTEDGE; cs.lpszClass = AfxRegisterWndClass(0); return TRUE; } void CMainFrame::OnSetFocus(CWnd* pOldWnd) { // forward focus to the view window if (m_pwndChildFrm) m_pwndChildFrm->SetFocus(); } BOOL CMainFrame::OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo) { // let the view have first crack at the command if (m_pwndChildFrm && m_pwndChildFrm->OnCmdMsg(nID, nCode, pExtra, pHandlerInfo)) return TRUE; // otherwise, do default handling return CFrameWnd::OnCmdMsg(nID, nCode, pExtra, pHandlerInfo); }

 

2. 子框架窗口

class CMyChildFrm : public CFrameWnd { DECLARE_DYNCREATE(CMyChildFrm) public: CMyChildFrm(); // protected constructor used by dynamic creation virtual ~CMyChildFrm(); public: virtual BOOL OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo); protected: CToolBar m_wndToolBar; CChildView m_wndView; afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct); afx_msg void OnSetFocus(CWnd *pOldWnd); DECLARE_MESSAGE_MAP() };

 

int CMyChildFrm::OnCreate(LPCREATESTRUCT lpCreateStruct) { if (CFrameWnd::OnCreate(lpCreateStruct) == -1) return -1; if (!m_wndView.Create(NULL, NULL, AFX_WS_DEFAULT_VIEW, CRect(0, 0, 0, 0), this, AFX_IDW_PANE_FIRST, NULL)) { TRACE0("Failed to create view window/n"); return -1; } if (!m_wndToolBar.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP | CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC) || !m_wndToolBar.LoadToolBar(IDR_CHILDFRAME)) { TRACE0("Failed to create toolbar/n"); return -1; // fail to create } m_wndToolBar.EnableDocking(CBRS_ALIGN_ANY); EnableDocking(CBRS_ALIGN_ANY); DockControlBar(&m_wndToolBar); return 0; } void CMyChildFrm::OnSetFocus(CWnd* pOldWnd) { // forward focus to the view window m_wndView.SetFocus(); } BOOL CMyChildFrm::OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo) { // let the view have first crack at the command if (m_wndView.OnCmdMsg(nID, nCode, pExtra, pHandlerInfo)) return TRUE; // otherwise, do default handling return CFrameWnd::OnCmdMsg(nID, nCode, pExtra, pHandlerInfo); }

 

3. 子框架窗口View

void CChildView::OnPaint() { CPaintDC dc(this); // device context for painting HDC hcompdc = CreateCompatibleDC(dc.m_hDC); ::SelectObject(hcompdc, m_bmp); CRect rect; GetClientRect(&rect); //CSize m_szBmp = m_bmp.GetBitmapDimension(); StretchBlt(dc.m_hDC, rect.left, rect.top, rect.right, rect.bottom, hcompdc, 0, 0, 588, 491, SRCCOPY); DeleteDC(hcompdc); dc.TextOut(100, 100, CString("Hello, Child Frame")); }
