当我们使用Windows资源管理器(Exporlor)时，看到左边的视图能够显示所选目标的相关信息，比较好用。
本例是一个简单的Web视图界面示例，不过左边不是一个Web视图，而是一个FormView。界面如下图所示：

本例是最简单的SDI工程，在View中创建了两个View：

int CXindowView::OnCreate(LPCREATESTRUCT lpCreateStruct) 
{
    if (CView::OnCreate(lpCreateStruct) == -1)
        return -1;

    /* 创建左右两个视图 */
    m_pForm = (CXindowForm *) okCreateView(RUNTIME_CLASS(CXindowForm), 1001);
    m_pList = (CXindowList *) okCreateView(RUNTIME_CLASS(CXindowList), 1002);
 
    m_pForm-＞m_pParent = this;

    return 0;
}     

void CXindowView::OnSize(UINT nType, int cx, int cy) 
{
    CView::OnSize(nType, cx, cy);
    int nFormWidth = 200;

    /* 如果窗口宽度＜400, 就隐藏左视图 */
    if(cx＞400)
    {
        if(m_pForm-＞GetSafeHwnd())  m_pForm-＞ShowWindow(SW_SHOW);
        if(m_pForm-＞GetSafeHwnd())  m_pForm-＞MoveWindow(0,0,nFormWidth,cy);
        if(m_pList-＞GetSafeHwnd())  m_pList-＞ShowWindow(SW_SHOW);
        if(m_pList-＞GetSafeHwnd())  m_pList-＞MoveWindow(nFormWidth,0,cx-nFormWidth,cy);
    }
    else
    {
        if(m_pForm-＞GetSafeHwnd())  m_pForm-＞ShowWindow(SW_HIDE);
        if(m_pList-＞GetSafeHwnd())  m_pList-＞ShowWindow(SW_SHOW);
        if(m_pList-＞GetSafeHwnd())  m_pList-＞MoveWindow(0,0,cx,cy);
    }
}

void CXindowForm::OnInitialUpdate() 
{
    CFormView::OnInitialUpdate();
    
    /* 相当于CListCtrl::SetItemData(), 用于区别是哪个CXLabel */
    m_add.SetCommand(1);
}

BOOL CXindowForm::OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult) 
{
    LPNMHDR pnmh = (LPNMHDR) lParam;
    
    if(pnmh-＞code==NM_LINKCLICK)
    {
        CXLabel* pLabel = (CXLabel *)GetDlgItem(pnmh-＞idFrom);
        CString str;

        /* GetCommand() */
        str.Format("d",pLabel-＞GetCommand());
        AfxMessageBox(str);

         if(m_pParent-＞GetSafeHwnd())
         {
             CListCtrl& listCtrl = ((CXindowView*)m_pParent)-＞m_pList-＞GetListCtrl();
             int nCount = listCtrl.GetItemCount();
 
             int nItem = listCtrl.InsertItem(nCount, "2003-8-15");
             listCtrl.SetItemText(nItem, 1, "192.168.3.1");
             listCtrl.SetItemText(nItem, 2, "www.vckbase.com");
             listCtrl.SetItemText(nItem, 3, "编程");
         }
    }
    return CFormView::OnNotify(wParam, lParam, pResult);
}
