这个最近比较常用，记录一下。

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! ");
      else
      {
           while (pos)
           {
                int nItem = m_list.GetNextSelectedItem(pos);
                TRACE1("Item %d was selected! ", 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;
      }
