帮助！如何获取clistctrl中行的当前背景色? [英] Help! How do you get the current background color of a row in a clistctrl?

问题描述

从下面的代码片段中可以看到，我可以使用自定义绘制设置clistctrl的任何行的颜色，而不会出现任何问题，但是我无法获得行的当前颜色.它只是返回垃圾.同样由于某种原因，CMFCListCtrl的其他成员似乎都没有.谁能告诉我我在做什么错.

As you can see from the code snippet below I can set the color of any row of a clistctrl using custom draw without any problem but I cannot get the current color of a row. It just returns rubbish. Also for some reason none of the other members of CMFCListCtrl seem to be there. Can anybody please tell me what I am doing wrong.

void CDDListCtrl::OnNMCustomdraw(NMHDR *pNMHDR, LRESULT *pResult)
{
NMLVCUSTOMDRAW* cd = reinterpret_cast<nmlvcustomdraw*>(pNMHDR);

*pResult = CDRF_DODEFAULT;

if ( CDDS_PREPAINT == cd->nmcd.dwDrawStage )

  *pResult = CDRF_NOTIFYITEMDRAW;
  }
else if ( CDDS_ITEMPREPAINT == cd->nmcd.dwDrawStage )
    {
  *pResult = CDRF_NOTIFYSUBITEMDRAW;
  }
else if ( (CDDS_ITEMPREPAINT | CDDS_SUBITEM) == cd->nmcd.dwDrawStage )
  {
    if (cd->nmcd.hdr.idFrom == IDC_PLAYLIST)
        {
        if (PlaylistInfo.m_AddDataType == ADD_TYPE_NORMAL)
            {
            if ((RegValue == SINGLE_MANUAL) || (RegValue == SINGLE_RANDOM) || (RegValue == SINGLE_FORMAT))
                {
                cd->clrTextBk = RED;
                }
            else
                {
                cd->clrTextBk = GREEN;
                }
            }
        }
    if (PlaylistInfo.m_AddDataType == ADD_TYPE_SEGUE)
        {
        if ( 1 == cd->iSubItem )
            {
        cd->clrTextBk = GetTextBkColor();
        SetTextBkColor(cd->clrTextBk);

推荐答案

不要只是不想在CDRF_SKIPDEFAULT时不返回CDRF_SKIPDEFAULT >?

Don''t you just want to NOT return CDRF_SKIPDEFAULT when it''s ADD_TYPE_SEGUE?
