C++ListControl颜色控制

1. 在头文件中加入

afx_msg void OnCustomdrawList ( NMHDR* pNMHDR, LRESULT* pResult );
2.在源文件中BEGIN_MESSAGE_MAP()  END_MESSAGE_MAP()中间加入

ON_NOTIFY (NM_CUSTOMDRAW,IDC_LIST, OnCustomdrawList)

<pre name="code" class="cpp">NM_CUSTOMDRAW 为消息类型， IDC_LIST为列表框ID， <span style="font-family: Arial, Helvetica, sans-serif;">OnCustomdrawList 是实现函数；</span>

3.实现部分

void CListControlBkColorDlg::OnCustomdrawList (NMHDR* pNMHDR, LRESULT* pResult)
{
NMLVCUSTOMDRAW* pLVCD = reinterpret_cast<NMLVCUSTOMDRAW*>( pNMHDR );
*pResult = CDRF_DODEFAULT;

if ( CDDS_PREPAINT == pLVCD->nmcd.dwDrawStage )
{
*pResult = CDRF_NOTIFYITEMDRAW;
}
else if (CDDS_ITEMPREPAINT == pLVCD->nmcd.dwDrawStage)
{
// This is the notification message for an item. We'll request
// notifications before each subitem's prepaint stage.
*pResult = CDRF_NOTIFYSUBITEMDRAW;
}
else if ( (CDDS_ITEMPREPAINT | CDDS_SUBITEM) == pLVCD->nmcd.dwDrawStage )
{
COLORREF crText, crBk;
int nItem = static_cast<int>(pLVCD->nmcd.dwItemSpec);
DWORD itemData = m_list.GetItemData(nItem);
if(itemData==0)
crBk = RGB(125,125,125);
else
crBk = RGB(0,0,65);

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(0,0,255);

pLVCD->clrText = crText;
pLVCD->clrTextBk = crBk;
// Tell Windows to paint the control itself.
*pResult = CDRF_DODEFAULT;
}
}
