CListCtrl详细使用方法

大家好,又见面了,我是你们的朋友全栈君。

以下未经说明,listctrl默认view 风格为report 相关类及处理函数 MFC:CListCtrl类 SDK:以 “ListView_”开头的一些宏。如 ListView_InsertColumn

CListCtrl 风格 LVS_ICON: 为每个item显示大图标 LVS_SMALLICON: 为每个item显示小图标 LVS_LIST: 显示一列带有小图标的item LVS_REPORT: 显示item详细资料 直观的理解:windows资源管理器,“查看”标签下的“大图标,小图标,列表,详细资料”

设置listctrl 风格及扩展风格 LONG lStyle; lStyle = GetWindowLong(m_list.m_hWnd, GWL_STYLE);//获取当前窗口style lStyle &= ~LVS_TYPEMASK; //清除显示方式位 lStyle |= LVS_REPORT; //设置style SetWindowLong(m_list.m_hWnd, GWL_STYLE, lStyle);//设置style

DWORD dwStyle = m_list.GetExtendedStyle(); dwStyle |= LVS_EX_FULLROWSELECT;//选中某行使整行高亮(只适用与report风格的listctrl) dwStyle |= LVS_EX_GRIDLINES;//网格线(只适用与report风格的listctrl) dwStyle |= LVS_EX_CHECKBOXES;//item前生成checkbox控件 m_list.SetExtendedStyle(dwStyle); //设置扩展风格

插入数据 m_list.InsertColumn( 0, “ID”, LVCFMT_LEFT, 40 );//插入列 m_list.InsertColumn( 1, “NAME”, LVCFMT_LEFT, 50 ); int nRow = m_list.InsertItem(0, “11”);//插入行 m_list.SetItemText(nRow, 1, “jacky”);//设置数据

一直选中item 选中style中的Show selection always,或者在上面第2点中设置LVS_SHOWSELALWAYS

选中和取消选中一行 int nIndex = 0; //选中 m_list.SetItemState(nIndex, LVIS_SELECTED|LVIS_FOCUSED, LVIS_SELECTED|LVIS_FOCUSED); //取消选中 m_list.SetItemState(nIndex, 0, LVIS_SELECTED|LVIS_FOCUSED);

得到listctrl中所有行的checkbox的状态 m_list.SetExtendedStyle(LVS_EX_CHECKBOXES); CString str; for(int i=0; i { if( m_list.GetItemState(i, LVIS_SELECTED) == LVIS_SELECTED || m_list.GetCheck(i)) { str.Format(_T(“第%d行的checkbox为选中状态”), i); AfxMessageBox(str); } }

得到listctrl中所有选中行的序号

方法一: CString str; for(int i=0; i { if( m_list.GetItemState(i, LVIS_SELECTED) == LVIS_SELECTED ) { str.Format(_T(“选中了第%d行”), i); AfxMessageBox(str); } } 方法二: POSITION pos = m_list.GetFirstSelectedItemPosition(); if (pos == NULL) TRACE0(“No items were selected!n”); else { while (pos) { int nItem = m_list.GetNextSelectedItem(pos); TRACE1(“Item %d was selected!n”, nItem); // you could do your own processing on nItem here } }

得到item的信息 TCHAR szBuf[1024]; LVITEM lvi; lvi.iItem = nItemIndex; lvi.iSubItem = 0; lvi.mask = LVIF_TEXT; lvi.pszText = szBuf; lvi.cchTextMax = 1024; m_list.GetItem(&lvi); 关于得到设置item的状态,还可以参考msdn文章 Q173242: Use Masks to Set/Get Item States in CListCtrl http://support.microsoft.com/kb/173242/en-us

得到listctrl的所有列的header字符串内容 LVCOLUMN lvcol; char str[256]; int nColNum; CString strColumnName[4];//假如有4列 nColNum = 0; lvcol.mask = LVCF_TEXT; lvcol.pszText = str; lvcol.cchTextMax = 256; while(m_list.GetColumn(nColNum, &lvcol)) { strColumnName[nColNum] = lvcol.pszText; nColNum ; }

使listctrl中一项可见,即滚动滚动条 m_list.EnsureVisible(i, FALSE);

得到listctrl列数 int nHeadNum = m_list.GetHeaderCtrl()->GetItemCount();

删除所有列 方法一: while ( m_list.DeleteColumn (0)) 因为你删除了第一列后,后面的列会依次向上移动。 方法二: int nColumns = 4; for (int i=nColumns-1; i>=0; i–) m_list.DeleteColumn (i);

得到单击的listctrl的行列号 添加listctrl控件的NM_CLICK消息相应函数

代码语言:javascript复制
void CTest6Dlg::OnClickList1(NMHDR* pNMHDR, LRESULT* pResult)
 {
       // 方法一:

   DWORD dwPos = GetMessagePos();
   CPoint point( LOWORD(dwPos), HIWORD(dwPos) );

   m_list.ScreenToClient(&point);

   LVHITTESTINFO lvinfo;
   lvinfo.pt = point;
   lvinfo.flags = LVHT_ABOVE;

   int nItem = m_list.SubItemHitTest(&lvinfo);
   if(nItem != -1)
   {
        CString strtemp;
        strtemp.Format("单击的是第%d行第%d列", lvinfo.iItem, lvinfo.iSubItem);
        AfxMessageBox(strtemp);
   }


  // 方法二:
  /*
   NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
   if(pNMListView->iItem != -1)
   {
        CString strtemp;
        strtemp.Format("单击的是第%d行第%d列",
                        pNMListView->iItem, pNMListView->iSubItem);
        AfxMessageBox(strtemp);
   }
  */
   *pResult = 0;
}

判断是否点击在listctrl的checkbox上 添加listctrl控件的NM_CLICK消息相应函数

代码语言:javascript复制
void CTest6Dlg::OnClickList1(NMHDR* pNMHDR, LRESULT* pResult)
 {
       DWORD dwPos = GetMessagePos();
       CPoint point( LOWORD(dwPos), HIWORD(dwPos) );

       m_list.ScreenToClient(&point);

      LVHITTESTINFO lvinfo;
      lvinfo.pt = point;
      lvinfo.flags = LVHT_ABOVE;

      UINT nFlag;
      int nItem = m_list.HitTest(point, &nFlag);
      //判断是否点在checkbox上
      if(nFlag == LVHT_ONITEMSTATEICON)
      {
             AfxMessageBox("点在listctrl的checkbox上");
      } 
       *pResult = 0;
   }

右键点击listctrl的item弹出菜单 添加listctrl控件的NM_RCLICK消息相应函数

代码语言:javascript复制
void CTest6Dlg::OnRclickList1(NMHDR* pNMHDR, LRESULT* pResult)
 {
   NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
   if(pNMListView->iItem != -1)
   {
        DWORD dwPos = GetMessagePos();
        CPoint point( LOWORD(dwPos), HIWORD(dwPos) );

        CMenu menu;
        VERIFY( menu.LoadMenu( IDR_MENU1 ) );
        CMenu* popup = menu.GetSubMenu(0);
        ASSERT( popup != NULL );
         popup->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, point.x, point.y, this );
   } 
   *pResult = 0;
 }

item切换焦点时(包括用键盘和鼠标切换item时),状态的一些变化顺序 添加listctrl控件的LVN_ITEMCHANGED消息相应函数

代码语言:javascript复制
 void CTest6Dlg::OnItemchangedList1(NMHDR* pNMHDR, LRESULT* pResult)
 {
   NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
   // TODO: Add your control notification handler code here

   CString sTemp;

   if((pNMListView->uOldState & LVIS_FOCUSED) == LVIS_FOCUSED && 
    (pNMListView->uNewState & LVIS_FOCUSED) == 0)
   {
        sTemp.Format("%d losted focus",pNMListView->iItem);
   }
   else if((pNMListView->uOldState & LVIS_FOCUSED) == 0 &&
       (pNMListView->uNewState & LVIS_FOCUSED) == LVIS_FOCUSED)
   {
        sTemp.Format("%d got focus",pNMListView->iItem);
   } 

   if((pNMListView->uOldState & LVIS_SELECTED) == LVIS_SELECTED &&
    (pNMListView->uNewState & LVIS_SELECTED) == 0)
   {
        sTemp.Format("%d losted selected",pNMListView->iItem);
   }
   else if((pNMListView->uOldState & LVIS_SELECTED) == 0 &&
    (pNMListView->uNewState & LVIS_SELECTED) == LVIS_SELECTED)
   {
        sTemp.Format("%d got selected",pNMListView->iItem);
   }

   *pResult = 0;
}
