参考别人代码，重载的一个 MFC 的 CListBox 的类。

ZListBox.h

class CZListBox : public CListBox{DECLARE_DYNAMIC(CZListBox)public:CZListBox();virtual ~CZListBox();protected:DECLARE_MESSAGE_MAP()private:CFont_Font;public:virtual void DrawItem(LPDRAWITEMSTRUCT /*lpDrawItemStruct*/);virtual void MeasureItem(LPMEASUREITEMSTRUCT /*lpMeasureItemStruct*/);virtual BOOL PreCreateWindow(CREATESTRUCT& cs);};

ZListBox.cpp

// CZListBoxIMPLEMENT_DYNAMIC(CZListBox, CListBox)CZListBox::CZListBox(){_Font.CreateFont( 14, 0, 0, 0, FW_NORMAL, FALSE, FALSE, 0, ANSI_CHARSET,OUT_DEFAULT_PRECIS, CLIP_DEFAULT_PRECIS, DEFAULT_QUALITY,DEFAULT_PITCH || FF_SWISS, _T("Consolas") );}CZListBox::~CZListBox(){_Font.DeleteObject();}BEGIN_MESSAGE_MAP(CZListBox, CListBox)END_MESSAGE_MAP()// CZListBox 消息处理程序BOOL CZListBox::PreCreateWindow(CREATESTRUCT& cs){cs.style &= ~LBS_SORT;cs.style |= LBS_OWNERDRAWFIXED;return CListBox::PreCreateWindow(cs);}void CZListBox::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct){LPCTSTR lpszText = (LPCTSTR)lpDrawItemStruct->itemData;CDC dc;dc.Attach( lpDrawItemStruct->hDC );CFont *pFont = dc.SelectObject( &_Font );if( ODS_SELECTED & lpDrawItemStruct->itemState ) {dc.SetTextColor( GetSysColor(COLOR_HIGHLIGHTTEXT) );dc.SetBkColor( GetSysColor(COLOR_HIGHLIGHT) );dc.FillSolidRect( &lpDrawItemStruct->rcItem, GetSysColor(COLOR_HIGHLIGHT) );lpDrawItemStruct->rcItem.left += 8;dc.DrawText( lpszText, _tcslen(lpszText), &lpDrawItemStruct->rcItem, DT_LEFT | \DT_SINGLELINE | DT_VCENTER );}else {dc.SetTextColor( RGB(0, 0, 0) );if( lpDrawItemStruct->itemID % 2 )dc.FillSolidRect( &lpDrawItemStruct->rcItem, RGB(238, 220, 130) );elsedc.FillSolidRect( &lpDrawItemStruct->rcItem, RGB(127, 255, 212) );dc.DrawText( lpszText, _tcslen(lpszText), &lpDrawItemStruct->rcItem, DT_LEFT | \DT_SINGLELINE | DT_VCENTER );}dc.SelectObject( pFont );dc.Detach();}void CZListBox::MeasureItem(LPMEASUREITEMSTRUCT lpMeasureItemStruct){lpMeasureItemStruct->itemHeight = 30;}

使用代码：

_ZListBox.Create( WS_CHILD |WS_VISIBLE | WS_BORDER | WS_VSCROLL | WS_HSCROLL | \LBS_OWNERDRAWVARIABLE, CRect(300, 20, 500, 220), this, IDC_LIST_BOX );_ZListBox.AddString( _T("Hello !") );_ZListBox.AddString( _T("What's this ?") );_ZListBox.AddString( _T("This is an apple !") );

效果图：
