  • CListCtrl用法简介及使用技巧（二）

    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;
      }

    --------------------------------------------------------------------------------

    20. listctrl的subitem添加图标

          m_list.SetExtendedStyle(LVS_EX_SUBITEMIMAGES);
          m_list.SetItem(..); //具体参数请参考msdn


    --------------------------------------------------------------------------------

    21. 在CListCtrl显示文件，并根据文件类型来显示图标

          网上找到的代码，share
         

     BOOL CTest6Dlg::OnInitDialog()
      {
           CDialog::OnInitDialog();
   
           HIMAGELIST himlSmall;
           HIMAGELIST himlLarge;
           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),

           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.Invalidate();
      m_list.UpdateWindow();
