MFC中窗口静态分割&视图切换

窗口静态分割

单个分割器

声明

首先在MainFrm.h中声明分割对象

CSplitterWnd m_wndSplitter;

准备视图

从CView或其派生类中派生四个类：CMyView1、CMyView2、CMyView3、CMyView4

静态分割窗口&添加视图

在MainFrm.cpp中添加虚函数OnCreateClient，添加如下代码

BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
    // TODO: 在此添加专用代码和/或调用基类
    CRect rectClient;
    GetClientRect(&rectClient);

    if (!m_wndSplitter.CreateStatic(this, 2, 2) ||
        !m_wndSplitter.CreateView(0, 0, RUNTIME_CLASS(CListView), CSize(rectClient.Width() / 2, rectClient.Height() / 2), pContext) ||
        !m_wndSplitter.CreateView(0, 1, RUNTIME_CLASS(CListView), CSize(rectClient.Width() / 2, rectClient.Height() / 2), pContext) ||
        !m_wndSplitter.CreateView(1, 0, RUNTIME_CLASS(CListView), CSize(rectClient.Width() / 2, rectClient.Height() / 2), pContext) ||
        !m_wndSplitter.CreateView(1, 1, RUNTIME_CLASS(CListView), CSize(rectClient.Width() / 2, rectClient.Height() / 2), pContext))
            return FALSE;


    // return CFrameWnd::OnCreateClient(lpcs, pContext);
    return TRUE;
}

使视图大小随窗口大小改变

在MainFrm.h中声明变量

BOOL m_bSplitter;

在MainFrm.cpp构造函数中初始化m_bSplitter

CMainFrame::CMainFrame() noexcept :
    m_bSplitter(FALSE)
{
}

在MainFrm.cpp虚函数OnCreateClient窗口分割之后添加对m_bSplitter的赋值

BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
    // TODO: 在此添加专用代码和/或调用基类
    CRect rectClient;
    GetClientRect(&rectClient);

    if (!m_wndSplitter.CreateStatic(this, 2, 2) ||
        !m_wndSplitter.CreateView(0, 0, RUNTIME_CLASS(CListView), CSize(rectClient.Width() / 2, rectClient.Height() / 2), pContext) ||
        !m_wndSplitter.CreateView(0, 1, RUNTIME_CLASS(CListView), CSize(rectClient.Width() / 2, rectClient.Height() / 2), pContext) ||
        !m_wndSplitter.CreateView(1, 0, RUNTIME_CLASS(CListView), CSize(rectClient.Width() / 2, rectClient.Height() / 2), pContext) ||
        !m_wndSplitter.CreateView(1, 1, RUNTIME_CLASS(CListView), CSize(rectClient.Width() / 2, rectClient.Height() / 2), pContext))
            return FALSE;

    m_bSplitter = TRUE; // 窗口已完成分割，视图已经动态创建

    // return CFrameWnd::OnCreateClient(lpcs, pContext);
    return TRUE;
}

在MainFrm.cpp中添加WM_SIZE消息映射，添加如下代码

void CMainFrame::OnSize(UINT nType, int cx, int cy)
{
    CFrameWnd::OnSize(nType, cx, cy);

    // TODO: 在此处添加消息处理程序代码
    if (m_bSplitter == TRUE)
    {
        m_wndSplitter.SetColumnInfo(0, cx / 2, 0);
        // 另外一列将自适应宽度
        m_wndSplitter.SetRowInfo(0, cy / 2, 0);
        // 另外一行将自适应高度

        // 重新计算
        m_wndSplitter.RecalcLayout();
    }
}

效果图

多个分割器

声明

声明两个分割器

CSplitterWnd m_wndSplitter1; // 主分割器
CSplitterWnd m_wndSplitter2; // 子分割器

静态分割窗口&添加视图

在MainFrm.cpp中修改虚函数OnCreateClient

BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
    // TODO: 在此添加专用代码和/或调用基类
    CRect rectClient;
    GetClientRect(&rectClient);

    if (!m_wndSplitter1.CreateStatic(this, 2, 1) ||
        !m_wndSplitter1.CreateView(0, 0, RUNTIME_CLASS(CListView), CSize(rectClient.Width(), rectClient.Height() / 2), pContext))
            return FALSE;

    if (!m_wndSplitter2.CreateStatic(&m_wndSplitter1, 1, 2, WS_CHILD | WS_VISIBLE, m_wndSplitter1.IdFromRowCol(1, 0)) ||
        !m_wndSplitter2.CreateView(0, 0, RUNTIME_CLASS(CListView), CSize(rectClient.Width() / 2, rectClient.Height() / 2), pContext) ||
        !m_wndSplitter2.CreateView(0, 1, RUNTIME_CLASS(CListView), CSize(rectClient.Width() / 2, rectClient.Height() / 2), pContext))
            return FALSE;

    m_bSplitter = TRUE; // 窗口已完成分割，视图已经动态创建

    // return CFrameWnd::OnCreateClient(lpcs, pContext);
    return TRUE;
}

使视图大小随窗口大小改变

相应地修改OnSize函数

void CMainFrame::OnSize(UINT nType, int cx, int cy)
{
    CFrameWnd::OnSize(nType, cx, cy);

    // TODO: 在此处添加消息处理程序代码
    if (m_bSplitter == TRUE)
    {
        m_wndSplitter1.SetRowInfo(0, cy / 2, 0);
        m_wndSplitter2.SetColumnInfo(0, cx / 2, 0);

        // 重新计算
        m_wndSplitter1.RecalcLayout();
        m_wndSplitter2.RecalcLayout();
    }
}

效果图

视图切换

在CMainFrame添加切换视图的函数BOOL CMainFrame::Switch(int nIndex),添加如下代码建立框架

BOOL CMainFrame::Switch(int nIndex)
{
    switch (nIndex)
    {
    case 0:
        break;
    case 1:
        break;
    default:
        return FALSE;
    }
    return TRUE;
}

视图之间的切换

声明

CSplitterWnd m_wndSplitter;

修改相应函数

添加CMyView2和CMyView3的绘图代码

CMyView2

void CMyView2::OnDraw(CDC* pDC)
{
    CRect rectClient;
    GetClientRect(rectClient);

    pDC->FillSolidRect(rectClient, RGB(255, 255, 255));
}

CMyView3

void CMyView3::OnDraw(CDC* pDC)
{
    CRect rectClient;
    GetClientRect(rectClient);

    pDC->FillSolidRect(rectClient, RGB(0, 0, 0));
}
修改OnCreateClient函数
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
    // TODO: 在此添加专用代码和/或调用基类
    CRect rectClient;
    GetClientRect(&rectClient);

    if (!m_wndSplitter.CreateStatic(this, 1, 2) ||
        !m_wndSplitter.CreateView(0, 0, RUNTIME_CLASS(CMyView1), CSize(rectClient.Width() / 2, rectClient.Height()), pContext) ||
        !m_wndSplitter.CreateView(0, 1, RUNTIME_CLASS(CMyView2), CSize(rectClient.Width() / 2, rectClient.Height()), pContext))
            return FALSE;

	m_bSplitter = TRUE; // 窗口已完成分割，视图已经动态创建

	Switch(0); // 更改数值以获得切换效果

	// return CFrameWnd::OnCreateClient(lpcs, pContext);
	return TRUE;
}
修改视图切换函数
BOOL CMainFrame::Switch(int nIndex)
{
    CRect rectClient;
    GetClientRect(rectClient);

    switch (nIndex)
    {
    case 0:
        m_wndSplitter.DeleteView(0, 1);
        m_wndSplitter.CreateView(0, 1, RUNTIME_CLASS(CMyView2), CSize(rectClient.Width() / 2, rectClient.Height()), NULL);
        m_wndSplitter.RecalcLayout();
        break;
    case 1:
        m_wndSplitter.DeleteView(0, 1);
        m_wndSplitter.CreateView(0, 1, RUNTIME_CLASS(CMyView3), CSize(rectClient.Width() / 2, rectClient.Height()), NULL);
        m_wndSplitter.RecalcLayout();
        break;
    default:
        return FALSE;
    }
    return TRUE;
}

代码中是通过删除原有视图重新建立要切换视图的方式来实现视图切换，如果因为数据量大，可以通过隐藏和显示视图来实现，这是我后来发现的方法，具体请参考我的另一篇随笔：MFC分割窗口(CSplitterWnd)与选项卡视图(CTabView)的混合使用

子分割器之间的切换

声明

CSplitterWnd m_wndSplitter; // 主分割器
CSplitterWnd m_wndSplitter1; // 子分割器1
CSplitterWnd m_wndSplitter2; // 子分割器2

准备视图

从CView或其派生类中派生第五个类：CMyView5

修改相应函数

修改OnCreateClient函数
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
    // TODO: 在此添加专用代码和/或调用基类
    CRect rectClient;
    GetClientRect(&rectClient);

    if (!m_wndSplitter.CreateStatic(this, 1, 2) ||
        !m_wndSplitter.CreateView(0,0,RUNTIME_CLASS(CMyView1),CSize(rectClient.Width() / 2, rectClient.Height()),pContext))
            return FALSE;

    if (!m_wndSplitter1.CreateStatic(&m_wndSplitter, 2, 1, WS_CHILD) ||
        !m_wndSplitter1.CreateView(0, 0, RUNTIME_CLASS(CMyView2), CSize(rectClient.Width() / 2, rectClient.Height() / 2), pContext) ||
	!m_wndSplitter1.CreateView(1, 0, RUNTIME_CLASS(CMyView3), CSize(rectClient.Width() / 2, rectClient.Height() / 2), pContext))
            return FALSE;

    if (!m_wndSplitter2.CreateStatic(&m_wndSplitter, 2, 1, WS_CHILD) ||
        !m_wndSplitter2.CreateView(0, 0, RUNTIME_CLASS(CMyView4), CSize(rectClient.Width() / 2, rectClient.Height() / 2), pContext) ||
        !m_wndSplitter2.CreateView(1, 0, RUNTIME_CLASS(CMyView5), CSize(rectClient.Width() / 2, rectClient.Height() / 2), pContext))
            return FALSE;

    m_bSplitter = TRUE; // 窗口已完成分割，视图已经动态创建

    Switch(0); // 更改数值以获得切换效果

    // return CFrameWnd::OnCreateClient(lpcs, pContext);
    return TRUE;
}
修改视图切换函数
BOOL CMainFrame::Switch(int nIndex)
{
    CRect rectClient;
    GetClientRect(rectClient);

    switch (nIndex)
    {
    case 0:
        ::SetWindowLong(m_wndSplitter1, GWL_ID, m_wndSplitter.IdFromRowCol(0, 1));
        m_wndSplitter1.ShowWindow(SW_SHOW);
        ::SetWindowLong(m_wndSplitter2, GWL_ID, AFX_IDW_PANE_FIRST);
        m_wndSplitter2.ShowWindow(SW_HIDE);
        break;
    case 1:
        ::SetWindowLong(m_wndSplitter1, GWL_ID, AFX_IDW_PANE_FIRST);
        m_wndSplitter1.ShowWindow(SW_HIDE);
        ::SetWindowLong(m_wndSplitter2, GWL_ID, m_wndSplitter.IdFromRowCol(0, 1));
        m_wndSplitter2.ShowWindow(SW_SHOW);
        break;
    default:
        return FALSE;
    }
    return TRUE;
}
