VC 自绘CListCtrl类

实现功能：鼠标在ListCtrl上滑动的时候，滑动到哪一行哪一行就高亮，有且仅有一条是高亮的。

如何实现下面两个功能：

1.当鼠标离开ListCtrl的时候，高亮行取消高亮。

2.更改高亮行的背景色，默认是蓝色的，客户想要其它的颜色。

    //自绘CListCtrl类，重载虚函数DrawItem  

    void CNewListCtrl::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)
    {
     // TODO: Add your code to draw the specified item
     ASSERT(lpDrawItemStruct->CtlType == ODT_LISTVIEW);
     CDC dc;
     dc.Attach(lpDrawItemStruct->hDC);
     ASSERT(NULL != dc.GetSafeHdc());
     // Save these value to restore them when done drawing.
     COLORREF crOldTextColor = dc.GetTextColor();
     COLORREF crOldBkColor = dc.GetBkColor();  

     // If this item is selected, set the background color
     // and the text color to appropriate values. Also, erase
     // rect by filling it with the background color.
     if ((lpDrawItemStruct->itemAction | ODA_SELECT) &&
      (lpDrawItemStruct->itemState & ODS_SELECTED))
     {
      dc.SetTextColor(::GetSysColor(COLOR_HIGHLIGHTTEXT));
      dc.SetBkColor(::GetSysColor(COLOR_HIGHLIGHT));
      dc.FillSolidRect(&lpDrawItemStruct->rcItem,
       ::GetSysColor(COLOR_HIGHLIGHT));
     }
     else
     {
      if(lpDrawItemStruct->itemID%2)
       dc.FillSolidRect(&lpDrawItemStruct->rcItem, RGB(128,128,128));
      else
       dc.FillSolidRect(&lpDrawItemStruct->rcItem, RGB(255,128,255));
     }  

     // If this item has the focus, draw a red frame around the
     // item's rect.
     if ((lpDrawItemStruct->itemAction | ODA_FOCUS) &&
      (lpDrawItemStruct->itemState & ODS_FOCUS))
     {
      CBrush br(RGB(0, 0, 128));
      dc.FrameRect(&lpDrawItemStruct->rcItem, &br);
     }  

     // Draw the text.
     CString strText(_T(""));
     CRect rcItem;  

     for(int i=0; i<GetHeaderCtrl()->GetItemCount(); i++)
     {
      strText = GetItemText(lpDrawItemStruct->itemID, i);
      GetSubItemRect(lpDrawItemStruct->itemID, i, LVIR_LABEL, rcItem);
      rcItem.left += 5;
      dc.DrawText(
       strText,
       strText.GetLength(),
       &rcItem,
      DT_LEFT|DT_SINGLELINE|DT_VCENTER);
     }  

     // Reset the background color and the text color back to their
     // original values.
     dc.SetTextColor(crOldTextColor);
     dc.SetBkColor(crOldBkColor);  

     dc.Detach();
    }  

    // 调用  

    CNewListCtrl m_list; // 类的成员变量  

    #define IDC_LIST 0x1101
     m_list.Create(WS_CHILD|WS_VISIBLE|WS_BORDER|WS_VSCROLL|WS_HSCROLL|LVS_OWNERDRAWFIXED, CRect(0, 0, 280, 280), this, IDC_LIST);
     m_list.ModifyStyle(0, LVS_REPORT|LVS_SINGLESEL);
     m_list.SetExtendedStyle(LVS_EX_FULLROWSELECT | LVS_EX_GRIDLINES);
     m_list.InsertColumn(0, _T("AAA"), LVCFMT_LEFT, 100);
     m_list.InsertColumn(1, _T("BBB"), LVCFMT_LEFT, 100);  

     CString strText(_T(""));
     for(int i=0; i<20; i++)
     {
      m_list.InsertItem(i, _T(""));
      strText.Format(_T("%d - Hello, World!"), i+1);
      m_list.SetItemText(i, 0, strText);
      strText.Format(_T("%d - ABCDEFG"), i+1);
      m_list.SetItemText(i, 1, strText);
     }  

显示效果如下图所示：
