CListCtrl 用法总结   

2009-02-26 09:40:51|  分类: 软件开发 |  标签: |举报 |字号 订阅

  下载LOFTER 我的照片书  |
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!\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;
  }
我自己是这样用滴~:
CMenu menuPopup;
if (menuPopup.CreatePopupMenu())
{
    DWORD dwPos = GetMessagePos();
    CPoint point( LOWORD(dwPos), HIWORD(dwPos) );
    CBitmap Bitmap1;
    Bitmap1.LoadBitmap(IDB_BITMAP20);

    menuPopup.AppendMenu(MF_STRING,IDC_BUTTON_1,"查看用户信息");
    menuPopup.AppendMenu(MF_STRING,IDC_BUTTON_2,"修改备注名称");
    menuPopup.AppendMenu(MF_STRING,IDC_BUTTON_3,"加入黑名单");
    menuPopup.AppendMenu(MF_STRING,IDC_BUTTON_4,"查看其状态");
    menuPopup.AppendMenu(MF_STRING,IDC_BUTTON_5,"加为好友");
    menuPopup.AppendMenu(MF_STRING,IDC_BUTTON_6,"右键菜单2");
   
menuPopup.AppendMenu(MF_STRING,IDC_BUTTON_6,&Bitmap1);//这里可以在右键添加一幅图片
    menuPopup.TrackPopupMenu(TPM_LEFTALIGN,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;
      }

           SHFILEINFO sfi;
           char  cSysDir[MAX_PATH];
           CString  strBuf;
 
           memset(cSysDir, 0, MAX_PATH);
 
           GetWindowsDirectory(cSysDir, MAX_PATH);
           strBuf = cSysDir;
           sprintf(cSysDir, "%s", strBuf.Left(strBuf.Find("\\")+1));
 
           himlSmall = (HIMAGELIST)SHGetFileInfo ((LPCSTR)cSysDir,
                      0,
                      &sfi,
                      sizeof(SHFILEINFO),
                      SHGFI_SYSICONINDEX | SHGFI_SMALLICON );
 
           himlLarge = (HIMAGELIST)SHGetFileInfo((LPCSTR)cSysDir,
                      0,
                      &sfi,
                      sizeof(SHFILEINFO),
                      SHGFI_SYSICONINDEX | SHGFI_LARGEICON);
 
           if (himlSmall && himlLarge)
           {
                ::SendMessage(m_list.m_hWnd, LVM_SETIMAGELIST,
                             (WPARAM)LVSIL_SMALL, (LPARAM)himlSmall);
                ::SendMessage(m_list.m_hWnd, LVM_SETIMAGELIST,
                             (WPARAM)LVSIL_NORMAL, (LPARAM)himlLarge);
           }
           return TRUE;  // return TRUE  unless you set the focus to a control
      }
 
      void CTest6Dlg::AddFiles(LPCTSTR lpszFileName, BOOL bAddToDocument)
      {
           int nIcon = GetIconIndex(lpszFileName, FALSE, FALSE);
           CString strSize;
           CFileFind filefind;
 
           //  get file size
           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)
      {
           SHFILEINFO sfi;
           memset(&sfi, 0, sizeof(sfi));
 
           if (bIsDir)
           {
            SHGetFileInfo(lpszPath,
                         FILE_ATTRIBUTE_DIRECTORY,
                         &sfi,
                         sizeof(sfi),
                         SHGFI_SMALLICON | SHGFI_SYSICONINDEX |
                         SHGFI_USEFILEATTRIBUTES |(bSelected ? 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();
