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)// Attributespublic:// Operationspublic:// 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// Implementationpublic:virtual ~CMainFrame();#ifdef _DEBUGvirtual void AssertValid() const;virtual void Dump(CDumpContext& dc) const;#endifprotected: // control bar embedded membersCStatusBar m_wndStatusBar;CToolBar m_wndToolBar;CMyChildFrm* m_pwndChildFrm;// Generated message map functionsprotected://{{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_MSGDECLARE_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 dockablem_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 cscs.dwExStyle &= ~WS_EX_CLIENTEDGE;cs.lpszClass = AfxRegisterWndClass(0);return TRUE;}void CMainFrame::OnSetFocus(CWnd* pOldWnd){// forward focus to the view windowif (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 commandif (m_pwndChildFrm && m_pwndChildFrm->OnCmdMsg(nID, nCode, pExtra, pHandlerInfo))return TRUE;// otherwise, do default handlingreturn 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 creationvirtual ~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 windowm_wndView.SetFocus();}BOOL CMyChildFrm::OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo){// let the view have first crack at the commandif (m_wndView.OnCmdMsg(nID, nCode, pExtra, pHandlerInfo))return TRUE;// otherwise, do default handlingreturn CFrameWnd::OnCmdMsg(nID, nCode, pExtra, pHandlerInfo);}

 

3. 子框架窗口View

void CChildView::OnPaint() {CPaintDC dc(this); // device context for paintingHDC 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"));}
