• CListCtrl使用(转)


    CListCtrl使用技巧

    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;
          }

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

               if (filefind.FindFile(lpszFileName))
               {
                    filefind.FindNextFile();
                    strSize.Format("%d", filefind.GetLength());
               }
               else
                    strSize = "0";
       
               // split path and filename
               CString strFileName = lpszFileName;
               CString strPath;
      
               int nPos = strFileName.ReverseFind('\');
               if (nPos != -1)
               {
                    strPath = strFileName.Left(nPos);
                    strFileName = strFileName.Mid(nPos + 1);
               }
       
               // insert to list
               int nItem = m_list.GetItemCount();
               m_list.InsertItem(nItem, strFileName, nIcon);
               m_list.SetItemText(nItem, 1, strSize);
               m_list.SetItemText(nItem, 2, strFileName.Right(3));
               m_list.SetItemText(nItem, 3, strPath);
          }
      
          int CTest6Dlg::GetIconIndex(LPCTSTR lpszPath, BOOL bIsDir, BOOL bSelected)

    35、listctrl查找定位  使用测试过还很好用 


    // 简单的查找函数
    // FindString(CListCtrl& , 查找内容 , 开始位置 , 到达底部时是否从头查找)

    int FindString(CListCtrl& list,LPCTSTR str,int startIndex,BOOL warp /* = TRUE */){
     int colCount = list.GetHeaderCtrl()->GetItemCount();
     CString* field = new CString[colCount];

     int index;
     if(startIndex < 0) index = 0;
     else index = startIndex + 1;

     BOOL isFind = FALSE;
     int out = -1;

     for(; index < list.GetItemCount(); index ++){
      for(int col = 0; col < colCount; col ++)
       field[col] = list.GetItemText(index,col);

      for(int col = 0; col < colCount; col ++){
       if(field[col].Find(str) != -1){
        out = index;
        isFind = TRUE;
        break;
       }
      }

      if(isFind) break;
     }

     delete[] field;
     field = 0;

     if(warp)
      if(!isFind)
       list.SetItemState(-1,0,LVIS_SELECTED);

     return out;


    /*************************************************/

    //测试
    CListCtrl& list;    // 需要查找的LIST
    CString str = "test";  //需要查找的字符串
    int index = -1;  //开始位置

    index = FindString(list,str,index,TRUE);
    if(index != -1){
      list.EnsureVisible(index,FALSE);
      list.SetItemState(index,LVIS_SELECTED,LVIS_SELECTED);
      list.SetFocus();
    }
