分享CListCtrl控件，如何修改当前选中行的颜色？
需求：修改选中行（FOCUSED & SELECTED）行背景和字体颜色。
默认当前选中行（获取焦点和选中状态）为蓝色高亮显示，我想修改当前鼠标点击行颜色为红色背景、白色前景。
如下自绘代码仅仅能实现，失去焦点后的行颜色修改。焦点状态依然是默认的蓝色高亮！如何修改这个默认的颜色呢？？？已经设置了FOCUSED和SELECTED颜色一致，可是没有任何效果展示。

NMLVCUSTOMDRAW* pLVCD = reinterpret_cast<NMLVCUSTOMDRAW*>(pNMHDR);
*pResult = 0;
int nItem = -111;
int nSubItem = -111;
COLORREF clrNewTextColor, clrNewBkColor;
//Switch between different draw stages
switch (pLVCD->nmcd.dwDrawStage) {
case CDDS_PREPAINT:
*pResult = CDRF_NOTIFYITEMDRAW;
break;
case CDDS_ITEMPREPAINT:
*pResult = CDRF_NOTIFYSUBITEMDRAW;
break;
case CDDS_ITEMPREPAINT | CDDS_SUBITEM:
nItem = static_cast<int>(pLVCD->nmcd.dwItemSpec); //获取当前重绘行索引
nSubItem = static_cast<int>(pLVCD->iSubItem); //获取当前重绘列索引
if (m_list.GetItemState(nItem, LVIS_FOCUSED|LVIS_SELECTED)) //如果重绘行就是选中的单元格所在的行
{
clrNewTextColor = RGB(255, 255, 255); //设置文本颜色
clrNewBkColor = RGB(255, 0, 0); //设置背景颜色
pLVCD->clrText = clrNewTextColor;
pLVCD->clrTextBk = clrNewBkColor;
}
else
{
clrNewTextColor = RGB(0, 0, 0);
clrNewBkColor = RGB(143, 193, 60);
pLVCD->clrText = clrNewTextColor;
pLVCD->clrTextBk = clrNewBkColor;
}
//else if (nSubItem == SelectCol) //如果重绘列是选中的单元格所在的列
//{
// clrNewTextColor = RGB(0, 0, 0);
// clrNewBkColor = RGB(230, 230, 250);
// pLVCD->clrText = clrNewTextColor;
// pLVCD->clrTextBk = clrNewBkColor;
//}
//else if (nSubItem > SelectCol) //只显示一列，如果没有这个判断就会显示后面所有列
//{
// clrNewTextColor = RGB(0, 0, 0);
// clrNewBkColor = RGB(255, 255, 255);
// pLVCD->clrText = clrNewTextColor;
// pLVCD->clrTextBk = clrNewBkColor;
//}
*pResult = CDRF_DODEFAULT;

对的，我这个写了，是为了在单元格里添加按钮的，你可以忽略这个步骤，直接自绘颜色就行，控件的属性要改成 owner Draw fixed

我想用NM_CUSTOMDRAW轻量级的自绘来实现，不知道如何做呢？

多谢。请问这个代码是需要从CListCtrl派生一个子类，然后重绘么？请明示。

DrawItem中重绘可以解决选中高亮颜色的问题
