• MFC ListControl用法


    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 );

          //新插入的在上面
           int nRow = m_list.InsertItem(0, "11");// 插入行
           m_list.SetItemText(nRow, 1, "jacky");// 设置其它列数据

        //新插入的数据在下面

       int nIndex = m_list.GetItemCount();
        LV_ITEM lvItem;
        lvItem.mask = LVIF_TEXT ; 
        lvItem.iItem = nIndex;     //行数
        lvItem.iSubItem = 0;
        lvItem.pszText = (char*)(LPCTSTR)strCount;   //第一列
        //在最后一行插入记录值.
             m_list.InsertItem(&lvItem); 
        //插入其它列
        m_list.SetItemText(nIndex,1,strLat); 
    -------------------------------------------------------------------------------- 
    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;
