有谁重载过CListCtrl控件??

Question

void CListCtrlEx::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)
{
//得到dc
LPDRAWITEMSTRUCT lpDIS = lpDrawItemStruct;
CDC* pDC = CDC::FromHandle(lpDIS->hDC); LVITEM lvi = {0};
lvi.mask = LVIF_STATE;//|LVIF_IMAGE;

lvi.iItem = lpDIS->itemID;
BOOL bGet = GetItem(&lvi); BOOL bHighlight =((lvi.state & LVIS_DROPHILITED)||((lvi.state & LVIS_SELECTED) && 
((GetFocus() == this)|| (GetStyle() & LVS_SHOWSELALWAYS)))); // 画文本背景
CRect rcBack = lpDIS->rcItem;
pDC->SetBkMode(TRANSPARENT);
if( bHighlight )
{
pDC->SetTextColor(::GetSysColor(COLOR_HIGHLIGHTTEXT));
pDC->SetBkColor(::GetSysColor(COLOR_HIGHLIGHT)); pDC->FillRect(rcBack, &CBrush(::GetSysColor(COLOR_HIGHLIGHT)));
}
else
{
if (lpDIS->itemID%2 ==0)
{
pDC->SetTextColor(0x0C0F80);

}
else
{
pDC->SetTextColor(RGB(0,128,255));
pDC->FillRect(rcBack, &CBrush(0xE3e3e3));
}
} //设置字体颜色
CString str; //得到焦点大小
CRect rcFocus = lpDIS->rcItem;
rcFocus.DeflateRect(1,1,1,1); if (lpDIS->itemAction & ODA_DRAWENTIRE)
{
//写文本
CString szText;
for (int i = 0; i < GetColumns(); i++)
