WTL中CHeaderCtrl列表头发生变化响应啥消息

HDN_BEGINTRACK
HDN_ENDTRACK

NOTIFY_HANDLER(ID_HEADERCTRL,HDN_BEGINTRACK,OnHdnBegintrack)
NOTIFY_HANDLER(ID_HEADERCTRL,HDN_ENDTRACK,OnHdnEndtrack)
或者用
MESSAGE_HANDLER(WM_NOTIFY,OnNotify)
都是可以的

class ListHeaderCtrl :    public CWindowWithReflectorImpl< ListHeaderCtrl , CHeaderCtrl >

    BEGIN_MSG_MAP(ListHeaderCtrl)
        REFLECTED_NOTIFY_CODE_HANDLER(HDN_BEGINTRACK,OnHeaderBeginTrack)
    END_MSG_MAP()

    LRESULT OnHeaderBeginTrack(int idCtrl, LPNMHDR pnmh, BOOL& bHandled);

LRESULT ListHeaderCtrl::OnHeaderEndTrack( int idCtrl, LPNMHDR pnmh, BOOL& bHandled )
{
    bHandled = TRUE;
    Invalidate(TRUE);
     ::InvalidateRect(GetParent(),NULL,FALSE);
    return S_OK;
}
