list contro控件根據單元格的內容改變顯示的顏色

第一首先向控件添加NM_CUSTOMDRAW消息。過程如下：

在頭文件中添加：

afx_msg void OnCustomdrawMyList(NMHDR *pNMHDR, LRESULT *pResult); 爲消息NM_CUSTOMDRAW的響應函數

在.CPP文件中添加

BEGIN_MESSAGE_MAP(CListControlDlg, CDialog)
//{{AFX_MSG_MAP(CListControlDlg)
ON_WM_SYSCOMMAND()
ON_WM_PAINT()
ON_WM_QUERYDRAGICON()
ON_NOTIFY ( NM_CUSTOMDRAW, IDC_LIST1, OnCustomdrawMyList ) //這句是你要添加的 其中IDC_LIST1控件的ID。
//}}AFX_MSG_MAP
END_MESSAGE_MAP()

以下爲重繪函數的實現過程：

void CListControlDlg::OnCustomdrawMyList(NMHDR *pNMHDR, LRESULT *pResult)
{
//設置整行的文字的顏色
/*
LPNMLVCUSTOMDRAW pLVCD = reinterpret_cast<LPNMLVCUSTOMDRAW>(pNMHDR);
*pResult = CDRF_DODEFAULT;
// TODO: 在此添加控件通知處理程序代碼
COLORREF crText;
if ( CDDS_PREPAINT == pLVCD->nmcd.dwDrawStage )
{
*pResult = CDRF_NOTIFYITEMDRAW;
}
else if ( CDDS_ITEMPREPAINT == pLVCD->nmcd.dwDrawStage )
{
*pResult = CDRF_NOTIFYSUBITEMDRAW;
}
else if (CDDS_ITEMPREPAINT == pLVCD->nmcd.dwDrawStage)
{                        
if ( (pLVCD->nmcd.dwItemSpec % 3) == 0)            
{
crText = RGB(255,0,0);        
}
else if((pLVCD->nmcd.dwItemSpec % 3) == 1) 
{
crText = RGB(0,255,0);
}                        
else  
{
crText = RGB(128,128,255); 
}
pLVCD->clrText = crText;
*pResult = CDRF_DODEFAULT;        
} 
*/
NMLVCUSTOMDRAW* pLVCD = reinterpret_cast<NMLVCUSTOMDRAW*>(pNMHDR);
*pResult = 0;
if ( CDDS_PREPAINT == pLVCD->nmcd.dwDrawStage )
{
*pResult = CDRF_NOTIFYITEMDRAW;
}
else if ( CDDS_ITEMPREPAINT == pLVCD->nmcd.dwDrawStage )
{
*pResult = CDRF_NOTIFYSUBITEMDRAW;
}
else if ( (CDDS_ITEMPREPAINT | CDDS_SUBITEM) == pLVCD->nmcd.dwDrawStage )
{
COLORREF m_clrText;
int nItem = static_cast<int> (pLVCD->nmcd.dwItemSpec);
// 判斷使ListCtrl不同顏色現實的條件
CString str = m_list.GetItemText(nItem ,2);//獲取控件第二列的值，m_list爲控件的變量
float m_height=(float)atof(str); 
if (m_height>80&&2==pLVCD->iSubItem)
{
// 設置該列紅色
m_clrText = RGB(255, 0, 0) ;
}
else
{
m_clrText = RGB(0, 0, 0) ;
}
pLVCD->clrText = m_clrText;
*pResult = CDRF_DODEFAULT;
}
}
