为CListCtrl添加item编辑功能

来源：互联网发布：升级显卡的软件编辑：程序博客网时间：2024/05/11 23:08

1、在dlg窗体添加一个CListCtrl 和一个CEdit
2、为此两控件对应绑定两成员变量，如下
CListCtrl m_List;
CEdit m_cTextEdit;
3、在dlg.h头文件添加两似有成员变量
private:
int m_nRow;
int m_nCol;

4、在oninitdialog初始化化listctrl 和edit
// 设置接收文件列表风格
LONG lStyle;
lStyle = GetWindowLong(m_List.m_hWnd, GWL_STYLE);
lStyle |= LVS_REPORT;
SetWindowLong(m_List.m_hWnd, GWL_STYLE, lStyle);

DWORD dwStyle = m_List.GetExtendedStyle();
dwStyle |= LVS_EX_FULLROWSELECT;
dwStyle |= LVS_EX_GRIDLINES;
m_List.SetExtendedStyle(dwStyle);

// 初始化列表头信息
m_List.InsertColumn( em_LIST_ITEM_KEY, "Key", LVCFMT_LEFT, 140 );
m_List.InsertColumn( em_LIST_ITEM_VALUE, "Value", LVCFMT_LEFT, 200 );

m_cTextEdit.ShowWindow( SW_HIDE );

5、为CListCtrl添加双击事件处理
void CXXXDlg::OnDblclkList1(NMHDR* pNMHDR, LRESULT* pResult)
{
// TODO: Add your control notification handler code here
char ach[MAX_LISTITME_LEN] = {0};
CRect cRectItem;
CRect cRectList;

NM_LISTVIEW* pNMListView = ( NM_LISTVIEW* )pNMHDR;

if ( -1 != pNMListView->iItem )
{
m_nRow = pNMListView->iItem;
m_nCol = pNMListView->iSubItem;

  //过滤key，key不允许修改
  if ( 0 == m_nCol)
  {
   *pResult = 0;
   return;
  }

  m_List.GetSubItemRect( pNMListView->iItem, pNMListView->iSubItem, LVIR_LABEL, cRectItem );
  m_List.GetWindowRect( &cRectList );
  ScreenToClient( &cRectList );

  cRectItem.left   += cRectList.left + 3;
  cRectItem.top    += cRectList.top;
  cRectItem.right += cRectList.left + 3;
  cRectItem.bottom += cRectList.top + 3;

  m_List.GetItemText( pNMListView->iItem, pNMListView->iSubItem, ach, MAX_LISTITME_LEN);
  m_cTextEdit.SetWindowText( ach );
  m_cTextEdit.ShowWindow( SW_SHOW );
  m_cTextEdit.MoveWindow( &cRectItem );
  m_cTextEdit.SetFocus();
  m_cTextEdit.CreateSolidCaret( 1, cRectItem.Height() - 5 );
  m_cTextEdit.ShowCaret();
  m_cTextEdit.SetSel( -1 );

}

*pResult = 0;
}

6、为m_cTextEdit添加光标消失事件处理
void CXXXDlg::OnKillfocusEditText()
{
// TODO: Add your control notification handler code here
CString cstrText = "";

m_cTextEdit.GetWindowText( cstrText );
m_List.SetItemText( m_nRow, m_nCol, cstrText );

m_cTextEdit.ShowWindow(SW_HIDE);
}

7、结束.
