昨天搞定了CListCtrl的编辑子项的问题

本文链接：https://blog.csdn.net/qiandayong/article/details/4301144

其实很简单, 用控件的SubItemHitTest方法确定选定子项, 然后调用EditLabel方法. 再将EditLabel方法进行子类化处理, 无非就是处理控件的LvnBeginlabeledit和LvnEndlabeledit消息, 源代码如下:

void CMultiPublishDlg::OnNMDblclkListCustomer(NMHDR *pNMHDR, LRESULT *pResult)
{
// TODO: 在此添加控件通知处理程序代码
*pResult = 0;

m_iItem = -1;
m_iSubItem = -1;

LPNMITEMACTIVATE lpNMItemActivate = (LPNMITEMACTIVATE)pNMHDR;

if(lpNMItemActivate != NULL)
{
  m_iItem = lpNMItemActivate->iItem;
  m_iSubItem = lpNMItemActivate->iSubItem;
}
//m_list_customer.EditLabel(nItem);//默认情况下，只能编辑主项
LVHITTESTINFO lvhit;
lvhit.pt = lpNMItemActivate->ptAction;
m_list_customer.SubItemHitTest(&lvhit);
if (lvhit.flags & LVHT_ONITEMLABEL)
{
  //m_list_customer.SetItemText(lvhit.iItem, lvhit.iSubItem, NULL);
  if (m_iItem != -1 && (lvhit.flags & LVHT_ONITEM))
  {
   if( m_iItem == lvhit.iItem && m_iSubItem == lvhit.iSubItem)
    m_list_customer.EditLabel(m_iItem);//需要将EditLabel进行子类化处理，以控制它出现的位置
  }
  else
  {
  }

}
}

void CMultiPublishDlg::OnLvnBeginlabeleditListCustomer(NMHDR *pNMHDR, LRESULT *pResult)
{
NMLVDISPINFO *pDispInfo = reinterpret_cast<NMLVDISPINFO*>(pNMHDR);
// TODO: 在此添加控件通知处理程序代码
if (m_iSubItem >= 0)
{
  ASSERT(m_iItem == pDispInfo->item.iItem);
  CRect rcSubItem;
  m_list_customer.GetSubItemRect( pDispInfo->item.iItem, m_iSubItem, LVIR_BOUNDS, rcSubItem);

  //get edit control and subclass
  //HWND hWnd = (HWND)SendMessage(LVM_GETEDITCONTROL);
  HWND hWnd = m_list_customer.GetEditControl()->m_hWnd;
  ASSERT(hWnd != NULL);
  VERIFY(m_edtItemEdit.SubclassWindow(hWnd));

  //move edit control text 4 pixel to the right of org label,
  //as Windows does it...编辑框定位
  m_edtItemEdit.m_iXPos = rcSubItem.left + 4;
  m_edtItemEdit.m_iWidth = rcSubItem.Width();
  m_edtItemEdit.SetWindowText(m_list_customer.GetItemText(pDispInfo->item.iItem, m_iSubItem));

}
*pResult = 0;
}

void CMultiPublishDlg::OnLvnEndlabeleditListCustomer(NMHDR *pNMHDR, LRESULT *pResult)
{
NMLVDISPINFO *pDispInfo = reinterpret_cast<NMLVDISPINFO*>(pNMHDR);
LV_ITEM *plvItem = &pDispInfo->item;
// TODO: 在此添加控件通知处理程序代码
if (m_iSubItem >= 0)
{
  if (plvItem->pszText != NULL )
  {
   m_list_customer.SetItemText(plvItem->iItem,m_iSubItem, plvItem->pszText);
  }

  VERIFY(m_edtItemEdit.UnsubclassWindow()!=NULL);
  *pResult = 0;

}

//编辑文本时对控件父窗口操作(如单击其它控件)引发"OnEndlabeledit"时刷新控件
CRect rect;
GetWindowRect(&rect);
CPoint point;
::GetCursorPos(&point);
if(!rect.PtInRect(point))
{
  m_iItem = -1;
  m_iSubItem = -1;
  //m_bFocus = FALSE;
  //m_bHighLight = FALSE;
}

//*pResult = TRUE;//允许更改item主项
}

至于其它效果, 以后再研究.

参考了vckbase.com的一篇文章才搞出来. 可能说法上不太一样.
