CListCtrl 使用技巧
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
--------------------------------------------------------------------------------
1. 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”
--------------------------------------------------------------------------------
2. 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 注：listview 的style 请查阅msdn http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wceshellui5/html/wce50lrflistviewstyles.asp
--------------------------------------------------------------------------------
3. 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
--------------------------------------------------------------------------------
4. 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
--------------------------------------------------------------------------------
5. 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);
--------------------------------------------------------------------------------
6. 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); } }
--------------------------------------------------------------------------------
7. 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 } }
--------------------------------------------------------------------------------
8. 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
--------------------------------------------------------------------------------
9. 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++; }
--------------------------------------------------------------------------------
10. 使listctrl 中一项可见，即滚动滚动条 m_list.EnsureVisible(i, FALSE);
--------------------------------------------------------------------------------
11. 得到listctrl 列数 int nHeadNum = m_list.GetHeaderCtrl()->GetItemCount();
--------------------------------------------------------------------------------
12. 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);
--------------------------------------------------------------------------------
13. 得到单击的listctrl 的行列号 添加listctrl 控件的NM_CLICK 消息相应函数 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; }
--------------------------------------------------------------------------------
14. 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 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; }
--------------------------------------------------------------------------------
15. 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 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; }
--------------------------------------------------------------------------------
16. 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 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; }

SHGFI_OPENICON : 0)); return sfi.iIcon; } else { SHGetFileInfo (lpszPath, FILE_ATTRIBUTE_NORMAL, &sfi, sizeof(sfi), SHGFI_SMALLICON | SHGFI_SYSICONINDEX | SHGFI_USEFILEATTRIBUTES | (bSelected ? SHGFI_OPENICON : 0)); return sfi.iIcon; } return -1; }
