转载：CListCtrl 使用介绍

转载地址：http://www.cnblogs.com/afarmer/archive/2012/03/31/2427217.html

列表控件可以看作是功能增强的ListBox，它提供了四种风格，而且可以同时显示一列的多中属性值。MFC中使用CListCtrl类来封装列表控件的各种操作。通过调用

BOOL Create( DWORD dwStyle, const RECT& rect, CWnd* pParentWnd, UINT nID );创建一个窗口，dwStyle中可以使用以下一些列表控件的专用风格：

LVS_ICON LVS_SMALLICON LVS_LIST LVS_REPORT 这四种风格决定控件的外观，同时只可以选择其中一种，分别对应：大图标显示，小图标显示，列表显示，详细报表显示
LVS_EDITLABELS 结点的显示字符可以被编辑，对于报表风格来讲可编辑的只为第一列。
LVS_SHOWSELALWAYS 在失去焦点时也显示当前选中的结点
LVS_SINGLESEL 同时只能选中列表中一项
 

下面是一些例子

作者：lixiaosan 时间：04/06/2006 以下未经说明，listctrl默认view 风格为report

1. CListCtrl 风格

      LVS_ICON: 为每个item显示大图标

      LVS_SMALLICON: 为每个item显示小图标

      LVS_LIST: 显示一列带有小图标的item

      LVS_REPORT: 显示item详细资料

      直观的理解：windows资源管理器，“查看”标签下的“大图标，小图标，列表，详细资料”

2. 设置listctrl 风格及扩展风格

      LONG lStyle;

      lStyle. = GetWindowLong(m_list.m_hWnd, GWL_STYLE);//获取当前窗口style

      lStyle. &= ~LVS_TYPEMASK; //清除显示方式位

      lStyle.|= LVS_REPORT; //设置style

      SetWindowLong(m_list.m_hWnd, GWL_STYLE, lStyle);//设置style

      DWORD dwStyle. = m_list.GetExtendedStyle();

      dwStyle.|= LVS_EX_FULLROWSELECT;//选中某行使整行高亮（只适用与report风格的listctrl）

      dwStyle.|= LVS_EX_GRIDLINES;//网格线（只适用与report风格的listctrl）

      dwStyle.|= LVS_EX_CHECKBOXES;//item前生成checkbox控件

      m_list.SetExtendedStyle(dwStyle); //设置扩展风格

      注：listview的style请查阅msdn http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wceshellui5/html/wce50lrflistviewstyles.asp

3. 插入数据

      m_list.InsertColumn( 0, "ID", LVCFMT_LEFT, 40 );//插入列

      m_list.InsertColumn( 1, "NAME", LVCFMT_LEFT, 50 );

      int nRow = m_list.InsertItem(0, “11”);//插入行

      m_list.SetItemText(nRow, 1, “jacky”);//设置数据

4. 一直选中item

选中style中的Show selection always，或者在上面第2点中设置LVS_SHOWSELALWAYS

5. 选中和取消选中一行

    int nIndex = 0;

    //选中

    m_list.SetItemState(nIndex, LVIS_SELECTED|LVIS_FOCUSED, LVIS_SELECTED|LVIS_FOCUSED);

    //取消选中

    m_list.SetItemState(nIndex, 0, LVIS_SELECTED|LVIS_FOCUSED);

6. 得到listctrl中所有行的checkbox的状态

      m_list.SetExtendedStyle(LVS_EX_CHECKBOXES);

      CString str;

      for(int i=0; i<m_list.GetItemCount(); i++)

      {

           if( m_list.GetItemState(i, LVIS_SELECTED) == LVIS_SELECTED || m_list.GetCheck(i))

           {

                str.Format(_T("第%d行的checkbox为选中状态"), i);

                AfxMessageBox(str);

           }

      }

7. 得到listctrl中所有选中行的序号

 
      方法一：

      CString str;

      for(int i=0; i<m_list.GetItemCount(); i++)

      {

           if( m_list.GetItemState(i, LVIS_SELECTED) == LVIS_SELECTED )

           {

                str.Format(_T("选中了第%d行"), i);

                AfxMessageBox(str);

           }

      }

      方法二：

      POSITION pos = m_list.GetFirstSelectedItemPosition();

      if (pos == NULL)

           TRACE0("No items were selected!\n");

      else

      {

           while (pos)

           {

                int nItem = m_list.GetNextSelectedItem(pos);

                TRACE1("Item %d was selected!\n", nItem);

                // you could do your own processing on nItem here

           }

      }

8. 得到item的信息

      TCHAR szBuf[1024];

      LVITEM lvi;

      lvi.iItem = nItemIndex;

      lvi.iSubItem = 0;

      lvi.mask = LVIF_TEXT;

      lvi.pszText = szBuf;

      lvi.cchTextMax = 1024;

      m_list.GetItem(&lvi);

      关于得到设置item的状态，还可以参考msdn文章

      Q173242: Use Masks to Set/Get Item States in CListCtrl http://support.microsoft.com/kb/173242/en-us

9. 得到listctrl的所有列的header字符串内容

      LVCOLUMN lvcol;

      char str[256];

      int   nColNum;

      CString strColumnName[4];//假如有4列

      nColNum = 0;

      lvcol.mask = LVCF_TEXT;

      lvcol.pszText = str;

      lvcol.cchTextMax = 256;

      while(m_list.GetColumn(nColNum, &lvcol))

      {

           strColumnName[nColNum] = lvcol.pszText;

           nColNum++;

      }

10. 使listctrl中一项可见，即滚动滚动条

     m_list.EnsureVisible(i, FALSE);

11. 得到listctrl列数

     int nHeadNum = m_list.GetHeaderCtrl()->GetItemCount();

12. 删除所有列

    方法一：

         while ( m_list.DeleteColumn (0))

       因为你删除了第一列后，后面的列会依次向上移动。

    方法二：

      int nColumns = 4;

      for (int i=nColumns-1; i>=0; i--)

          m_list.DeleteColumn (i);

13. 得到单击的listctrl的行列号

      添加listctrl控件的NM_CLICK消息相应函数

      void CTest6Dlg::OnClickList1(NMHDR* pNMHDR, LRESULT* pResult)

      {

           // 方法一：

           /*

           DWORD dwPos = GetMessagePos();

           CPoint point( LOWORD(dwPos), HIWORD(dwPos) );

           m_list.ScreenToClient(&point);

           LVHITTESTINFO lvinfo;

           lvinfo.pt = point;

           lvinfo.flags = LVHT_ABOVE;

           int nItem = m_list.SubItemHitTest(&lvinfo);

           if(nItem != -1)

           {

                CString strtemp;

                strtemp.Format("单击的是第%d行第%d列", lvinfo.iItem, lvinfo.iSubItem);

                AfxMessageBox(strtemp);

           }

          */

          // 方法二:

          /*

           NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;

           if(pNMListView->iItem != -1)

           {

                CString strtemp;

                strtemp.Format("单击的是第%d行第%d列",

                                pNMListView->iItem, pNMListView->iSubItem);

                AfxMessageBox(strtemp);

           }

          */

           *pResult = 0;

      }

14. 判断是否点击在listctrl的checkbox上

      添加listctrl控件的NM_CLICK消息相应函数

      void CTest6Dlg::OnClickList1(NMHDR* pNMHDR, LRESULT* pResult)

      {

           DWORD dwPos = GetMessagePos();

           CPoint point( LOWORD(dwPos), HIWORD(dwPos) );

           m_list.ScreenToClient(&point);

           LVHITTESTINFO lvinfo;

           lvinfo.pt = point;

           lvinfo.flags = LVHT_ABOVE;

           UINT nFlag;

           int nItem = m_list.HitTest(point, &nFlag);

           //判断是否点在checkbox上

           if(nFlag == LVHT_ONITEMSTATEICON)

           {

                AfxMessageBox("点在listctrl的checkbox上");

           }

           *pResult = 0;

      }

15. 右键点击listctrl的item弹出菜单

      添加listctrl控件的NM_RCLICK消息相应函数

      void CTest6Dlg::OnRclickList1(NMHDR* pNMHDR, LRESULT* pResult)

      {

           NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;

           if(pNMListView->iItem != -1)

           {

                DWORD dwPos = GetMessagePos();

                CPoint point( LOWORD(dwPos), HIWORD(dwPos) );

                CMenu menu;

                VERIFY( menu.LoadMenu( IDR_MENU1 ) );

                CMenu* popup = menu.GetSubMenu(0);

                ASSERT( popup != NULL );

                popup->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, point.x, point.y, this );

           }

           *pResult = 0;

}

16. item切换焦点时(包括用键盘和鼠标切换item时)，状态的一些变化顺序

      添加listctrl控件的LVN_ITEMCHANGED消息相应函数

      void CTest6Dlg::OnItemchangedList1(NMHDR* pNMHDR, LRESULT* pResult)

      {

           NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;

           // TODO: Add your control notification handler code here

           CString sTemp;

           if((pNMListView->uOldState & LVIS_FOCUSED) == LVIS_FOCUSED &&

            (pNMListView->uNewState & LVIS_FOCUSED) == 0)

           {

                sTemp.Format("%d losted focus",pNMListView->iItem);

           }

           else if((pNMListView->uOldState & LVIS_FOCUSED) == 0 &&

               (pNMListView->uNewState & LVIS_FOCUSED) == LVIS_FOCUSED)

           {

                sTemp.Format("%d got focus",pNMListView->iItem);

           }

           if((pNMListView->uOldState & LVIS_SELECTED) == LVIS_SELECTED &&

            (pNMListView->uNewState & LVIS_SELECTED) == 0)

           {

                sTemp.Format("%d losted selected",pNMListView->iItem);

           }

           else if((pNMListView->uOldState & LVIS_SELECTED) == 0 &&

            (pNMListView->uNewState & LVIS_SELECTED) == LVIS_SELECTED)

           {

                sTemp.Format("%d got selected",pNMListView->iItem);

           }

           *pResult = 0;

      }

      m_list.SetItem(..); //具体参数请参考msdn

21. 在CListCtrl显示文件，并根据文件类型来显示图标

      网上找到的代码，share

      BOOL CTest6Dlg::OnInitDialog()

      {

           CDialog::OnInitDialog();

           HIMAGELIST himlSmall;
