MFC ListCtrl 用法详细举例

1.ListCtrl 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

 

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

 

 

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 selectionalways，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
     {
          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);
          }
     }

CString strIns;
strIns="delete from tmpStatByGround";
m_pRs.CreateInstance(__uuidof(Recordset));
m_pRs->CursorLocation = adUseClient;
m_pRs->Open((LPCTSTR)strIns, vDispatch,adOpenKeyset,
adLockOptimistic, adCmdUnknown);

7. 得到listctrl中所有选中行的序号
     方法一：
     CString str;
     for(int i=0; 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);

 

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：
          
 
         // 方法二:
         
          *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 lostedfocus",pNMListView->iItem);
          }
          else if((pNMListView->uOldState &LVIS_FOCUSED) == 0 &&
              (pNMListView->uNewState &LVIS_FOCUSED) == LVIS_FOCUSED)
          {
               sTemp.Format("%d gotfocus",pNMListView->iItem);
          }

          if((pNMListView->uOldState &LVIS_SELECTED) == LVIS_SELECTED&&
           (pNMListView->uNewState &LVIS_SELECTED) == 0)
          {
               sTemp.Format("%d lostedselected",pNMListView->iItem);
          }
          else if((pNMListView->uOldState &LVIS_SELECTED) == 0 &&
           (pNMListView->uNewState &LVIS_SELECTED) == LVIS_SELECTED)
          {
