  • MFC中ClistCtrl的=NM_CUSTOMDRAW消息

    =NM_CUSTOMDRAW是你点击列表内部是的消息映射:

    例如:我想在我删除一行列表的数据,但是删除后下一行数据继续保持高亮状态

    void CChildView::OnDel()
    {
        int count = m_list.GetSelectionMark();
    
    
        if (count == -1)
         {
             AfxMessageBox(_T("请先选中一行在删除!"));
             return;
         }
         m_list.DeleteItem(count);
         TRACE("%d
    ", count);
         m_list.SetSelectionMark(count);
    }
    void CChildView::OnNMCustomdraw(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)
            {
                *pResult = CDRF_NOTIFYSUBITEMDRAW;
            }
            else if ((CDDS_ITEMPREPAINT | CDDS_SUBITEM) == pLVCD->nmcd.dwDrawStage)
            {
    
                COLORREF clrNewTextColor, clrNewBkColor;
    
                int nItem = static_cast<int>(pLVCD->nmcd.dwItemSpec);
    
                int index = m_list.GetSelectionMark();
    
                if (index == nItem)//如果要刷新的项为当前选择的项,则将文字设为白色,背景色设为蓝色
                {
                    clrNewTextColor = RGB(255, 255, 255);        //Set the text to white
                    clrNewBkColor = RGB(49, 106, 197);        //Set the background color to blue
                }
                else
                {
                    clrNewTextColor = RGB(0, 0, 0);        //set the text black
                    clrNewBkColor = RGB(255, 255, 255);    //leave the background color white
                }
    
                pLVCD->clrText = clrNewTextColor;
                pLVCD->clrTextBk = clrNewBkColor;
    
                *pResult = CDRF_DODEFAULT;
            }
    }
