如何设置ListViewCtrl的最小列宽（How to set a minimum column width）

NOTIFY_CODE_HANDLER(HDN_TRACK, OnColumnDraging)

NOTIFY_CODE_HANDLER(HDN_ITEMCHANGING, OnColumnDraging)

LRESULT CListViewComponent::OnColumnDraging(int wParam, LPNMHDR lParam, BOOL &bHandled){    HD_NOTIFY *pHDN = (HD_NOTIFY*)lParam;    if (pHDN->pitem->mask & HDI_WIDTH && pHDN->pitem->cxy < m_nMinColumnWidth && pHDN->pitem->cxy >= 0)    {        pHDN->pitem->cxy = m_nMinColumnWidth;    }        bHandled = FALSE;        return 0L;}

响应列被拖动时的NOTIFY消息HDN_TRACK，在这里判断是否列宽已经小于最小宽度，详见代码。
