大家好,又见面了,我是你们的朋友全栈君。

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 {
    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 {
    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;
    }
