MFC控件：listctrl使用方法总结

以下未经说明，listctrl默认view 风格为report

相关类及处理函数

MFC：CListCtrl类

SDK：以 “ListView_”开头的一些宏。如 ListView_InsertColumn

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

8.1 得到选中的行的每一项的信息

得到具体的某一项：

CString str;
int nId;
//首先得到点击的位置
POSITION pos=m_listcontrol.GetFirstSelectedItemPosition();
if(pos==NULL)
{
MessageBox("请至少选择一项","娃子理财",MB_ICONEXCLAMATION);
return;
}
//得到行号，通过POSITION转化
nId=(int)m_listcontrol.GetNextSelectedItem(pos);
//得到列中的内容（0表示第一列，同理1,2,3...表示第二，三，四...列）
str=m_listcontrol.GetItemText(nId,0);
str=m_listcontrol.GetItemText(nId,1);

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;
   }

   }

   void CTest6Dlg::AddFiles(LPCTSTR lpszFileName, BOOL bAddToDocument)
   {
      int nIcon = GetIconIndex(lpszFileName, FALSE, FALSE);
      CString strSize;

​      return  sfi.iIcon;
​      }
​      return -1;
   }
