CListCtrl用法（轉）

來自：http://blog.csdn.net/wuyijc/archive/2009/02/26/3938871.aspx
1. CListCtrl 風格
      LVS_ICON: 為每個item顯示大圖標
      LVS_SMALLICON: 為每個item顯示小圖標
      LVS_LIST: 顯示一列帶有小圖標的item
      LVS_REPORT: 顯示item詳細資料

直觀的理解：windows資源管理器，“查看”標簽下的“大圖標，小圖標，列表，詳細資料”

--------------------------------------------------------------------------------

2. 設置listctrl 風格及擴展風格
      LONG lStyle;
      lStyle = GetWindowLong(m_list.m_hWnd, GWL_STYLE);//獲取當前窗口style
      lStyle &= ~LVS_TYPEMASK; //清除顯示方式位
      lStyle |= LVS_REPORT; //設置style
      SetWindowLong(m_list.m_hWnd, GWL_STYLE, lStyle);//設置style

      DWORD dwStyle = m_list.GetExtendedStyle();
      dwStyle |= LVS_EX_FULLROWSELECT;//選中某行使整行高亮（只適用與report風格的listctrl）
      dwStyle |= LVS_EX_GRIDLINES;//網格線（只適用與report風格的listctrl）
      dwStyle |= LVS_EX_CHECKBOXES;//item前生成checkbox控件
      m_list.SetExtendedStyle(dwStyle); //設置擴展風格

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

--------------------------------------------------------------------------------

3. 插入數據
      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”);//設置數據

--------------------------------------------------------------------------------

4. 一直選中item
選中style中的Show selection always，或者在上面第2點中設置LVS_SHOWSELALWAYS

--------------------------------------------------------------------------------

5. 選中和取消選中一行
    int nIndex = 0;
    //選中
    m_list.SetItemState(nIndex, LVIS_SELECTED|LVIS_FOCUSED, LVIS_SELECTED|LVIS_FOCUSED);
    //取消選中
    m_list.SetItemState(nIndex, 0, LVIS_SELECTED|LVIS_FOCUSED);

--------------------------------------------------------------------------------

6. 得到listctrl中所有行的checkbox的狀態
      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為選中狀態"), i);
                AfxMessageBox(str);
           }
      }

--------------------------------------------------------------------------------

7. 得到listctrl中所有選中行的序號
      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("選中了第%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);

      關于得到設置item的狀態，還可以參考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字符串內容
      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中一項可見，即滾動滾動條
m_list.EnsureVisible(i, FALSE);

--------------------------------------------------------------------------------

11. 得到listctrl列數
int nHeadNum = m_list.GetHeaderCtrl()->GetItemCount();

--------------------------------------------------------------------------------

12. 刪除所有列
      方法一：
         while ( m_list.DeleteColumn (0))
       因為你刪除了第一列后，后面的列會依次向上移動。

      方法二：
      int nColumns = 4;
      for (int i=nColumns-1; i>=0; i--)
          m_list.DeleteColumn (i);

--------------------------------------------------------------------------------

13. 得到單擊的listctrl的行列號
      添加listctrl控件的NM_CLICK消息相應函數
      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("單擊的是第%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("單擊的是第%d行第%d列",
                                pNMListView->iItem, pNMListView->iSubItem);
                AfxMessageBox(strtemp);
           }
          */
           *pResult = 0;
      }

--------------------------------------------------------------------------------

14. 判斷是否點擊在listctrl的checkbox上
      添加listctrl控件的NM_CLICK消息相應函數
      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);
           //判斷是否點在checkbox上
           if(nFlag == LVHT_ONITEMSTATEICON)
           {
                AfxMessageBox("點在listctrl的checkbox上");
           }
           *pResult = 0;
      }

--------------------------------------------------------------------------------

15. 右鍵點擊listctrl的item彈出菜單
      添加listctrl控件的NM_RCLICK消息相應函數
      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切換焦點時(包括用鍵盤和鼠標切換item時)，狀態的一些變化順序
      添加listctrl控件的LVN_ITEMCHANGED消息相應函數
      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;
      }

                      sizeof(SHFILEINFO),
                      SHGFI_SYSICONINDEX | SHGFI_SMALLICON );

           himlLarge = (HIMAGELIST)SHGetFileInfo((LPCSTR)cSysDir,

           CString strPath;

           int nPos = strFileName.ReverseFind('\\');
           if (nPos != -1)
