CListCtrl详细使用方法

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;}

SHGFI_OPENICON : 0));      return  sfi.iIcon;   }   else   {    SHGetFileInfo (lpszPath,                   FILE_ATTRIBUTE_NORMAL,                   &sfi,                   sizeof(sfi),                   SHGFI_SMALLICON | SHGFI_SYSICONINDEX |                   SHGFI_USEFILEATTRIBUTES | (bSelected ? SHGFI_OPENICON : 0));    return   sfi.iIcon;   }   return  -1;}

22. listctrl内容进行大数据量更新时，避免闪烁
    m_list.SetRedraw(FALSE);
    //更新内容
    m_list.SetRedraw(TRUE);
    m_list.Invalidate();
    m_list.UpdateWindow();
