MFC 窗口分割
动态分割窗口:
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext) { if (m_WndSplitter.Create(this, 2, 2, CSize(10, 10), pContext)) { return TRUE; } else { return false; } //return CFrameWnd::OnCreateClient(lpcs, pContext); }
静态分割窗口:
为MainFrame类添加两个成员变量如下,并重载虚函数OnCreateClient,以实现窗口分割。
CSplitterWnd m_WndSplitter1;
CSplitterWnd m_WndSplitter2;
virtual BOOL OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext);
以CView为基类创建CView2,CView3,CView4类。
在MainFrame.cpp包含所有视图头文件
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext) { CRect rect; GetClientRect(&rect); m_WndSplitter1.CreateStatic(this,3,1); //创建一个静态分栏窗口,分为3行一列 m_WndSplitter1.CreateView(0, 0, RUNTIME_CLASS(C窗口分割2View), CSize(100, 100), pContext); //连接0行0列窗格 m_WndSplitter1.CreateView(1, 0, RUNTIME_CLASS(CView2), CSize(100, 100), pContext); //用cview2连接1行0列窗格 //将两行0列再分开1行2列 if (!m_WndSplitter2.CreateStatic(&m_WndSplitter1, 1, 2, WS_CHILD | WS_VISIBLE, m_WndSplitter1.IdFromRowCol(2, 0))) return FALSE; m_WndSplitter2.CreateView(0, 0, RUNTIME_CLASS(CView3), CSize(400, 300), pContext); //用cview3连接到第二个分行对象0行0列窗格 m_WndSplitter2.CreateView(0, 1, RUNTIME_CLASS(CView4), CSize(400, 300), pContext); //用cview4连接到第二个分行对象0行1列窗格 return TRUE; }
固定分割窗口的分割线:
以 CSplitterWnd为基类,创建新的CFixSplitterWnd 类,并在CFixSplitterWnd 类中手动添加WM_LBUTTONDOWN、WM_MOUSEMOVE、WM_SETCURSOR消息的消息映射和消息响应函数。
CFixSplitterWnd 类代码如下:
class CFixSplitterWnd : public CSplitterWnd { public: CFixSplitterWnd(BOOL b_lock=TRUE); virtual ~CFixSplitterWnd(); public: BOOL m_block; void Lock() { m_block = true; } //锁定分割线 void UnLock() { m_block = FALSE; } //不锁定分割线 DECLARE_MESSAGE_MAP() afx_msg void OnLButtonDown(UINT nFlags, CPoint point); afx_msg void OnMouseMove(UINT nFlags, CPoint point); afx_msg BOOL OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message); };
CFixSplitterWnd::CFixSplitterWnd(BOOL b_lock) { m_block = b_lock; } CFixSplitterWnd::~CFixSplitterWnd() { } BEGIN_MESSAGE_MAP(CFixSplitterWnd, CSplitterWnd) ON_WM_LBUTTONDOWN() ON_WM_MOUSEMOVE() ON_WM_SETCURSOR() END_MESSAGE_MAP() void CFixSplitterWnd::OnLButtonDown(UINT nFlags, CPoint point) { // TODO: Add your message handler code here and/or call default if (!m_block) CSplitterWnd::OnLButtonDown(nFlags, point); else CWnd::OnLButtonDown(nFlags,point); } void CFixSplitterWnd::OnMouseMove(UINT nFlags, CPoint point) //移动鼠标 { // TODO: Add your message handler code here and/or call default if (!m_block) CSplitterWnd::OnMouseMove(nFlags, point); else CWnd::OnMouseMove(nFlags, point); } BOOL CFixSplitterWnd::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message) //设置光标 { // TODO: Add your message handler code here and/or call default if (!m_block) return CSplitterWnd::OnSetCursor(pWnd, nHitTest, message); else return CWnd::OnSetCursor(pWnd, nHitTest, message); }
在CMainFrame类中 ,m_WndSplitter1、 m_WndSplitter2的基类由 CSplitterWnd 设置为 CFixSplitterWnd.重载的 OnCreateClient 代码如下.
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext) { // TODO: Add your specialized code here and/or call the base class m_WndSplitter1.Lock(); m_WndSplitter2.UnLock(); m_WndSplitter1.CreateStatic(this, 3, 1); m_WndSplitter1.CreateView(0, 0, RUNTIME_CLASS(C窗口分割3View), CSize(100, 100), pContext);//连接0行0列窗格 m_WndSplitter1.CreateView(1, 0, RUNTIME_CLASS(CView2), CSize(100, 100), pContext);//用cview2连接1行0列窗格 //将两行0列再分开1行2列 if (!m_WndSplitter2.CreateStatic(&m_WndSplitter1, 1, 2, WS_CHILD | WS_VISIBLE, m_WndSplitter1.IdFromRowCol(2, 0))) return FALSE; m_WndSplitter2.CreateView(0, 0, RUNTIME_CLASS(CView3), CSize(400, 300), pContext);//用cview3连接到第二个分行对象0行0列窗格 m_WndSplitter2.CreateView(0, 1, RUNTIME_CLASS(CView4), CSize(400, 300), pContext);//用cview4连接到第二个分行对象0行1列窗格 return TRUE; // return CFrameWnd::OnCreateClient(lpcs, pContext); }
