【原】CListCtrl 使用技巧
作者：lixiaosan时间：04/06/2006
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://www.nigeriaembassy.cn/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; iGetItemCount();
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; www.nigeriaembassy.cn = 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; www.nigeriaembassy.cn = 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; }

20. listctrl的subitem添加图标
m_list.SetExtendedStyle(LVS_EX_SUBITEMIMAGES); m_list.SetItem(..); //具体参数请参考msdn
21. 在CListCtrl显示文件，并根据文件类型来显示图标
网上找到的代码，share BOOL CTest6Dlg::OnInitDialog() { CDialog::OnInitDialog(); HIMAGELIST himlSmall; HIMAGELIST himlLarge; SHFILEINFO sfi; char cSysDir[MAX_PATH]; CString strBuf; memset(cSysDir, 0, MAX_PATH); GetWindowsDirectory(cSysDir, MAX_PATH); strBuf = cSysDir; sprintf(cSysDir, "%s", strBuf.Left(strBuf.Find("//")+1)); himlSmall = (HIMAGELIST)SHGetFileInfo ((LPCSTR)cSysDir, 0, &sfi, sizeof(SHFILEINFO), SHGFI_SYSICONINDEX | SHGFI_SMALLICON ); himlLarge = (HIMAGELIST)SHGetFileInfo((LPCSTR)cSysDir, 0, &sfi, sizeof(SHFILEINFO), SHGFI_SYSICONINDEX | SHGFI_LARGEICON); if (himlSmall && himlLarge) { ::SendMessage(m_list.m_hWnd, LVM_SETIMAGELIST, (WPARAM)LVSIL_SMALL, (LPARAM)himlSmall); ::SendMessage(m_list.m_hWnd, LVM_SETIMAGELIST, (WPARAM)LVSIL_NORMAL, (LPARAM)himlLarge); } return TRUE; // return TRUE unless you set the focus to a control } void CTest6Dlg::AddFiles(LPCTSTR lpszFileName, BOOL bAddToDocument) { int nIcon = GetIconIndex(lpszFileName, FALSE, FALSE); CString strSize; CFileFind filefind; // get file size if (filefind.FindFile(lpszFileName)) { filefind.FindNextFile(); strSize.Format("%d", filefind.GetLength()); } else strSize = "0"; // split path and filename CString strFileName = lpszFileName; CString strPath; int nPos = strFileName.ReverseFind('//'); if (nPos != -1) { strPath = strFileName.Left(nPos); strFileName = strFileName.Mid(nPos + 1); } // insert to list int nItem = m_list.GetItemCount(); m_list.InsertItem(nItem, strFileName, nIcon); m_list.SetItemText(nItem, 1, strSize); m_list.SetItemText(nItem, 2, strFileName.Right(3)); m_list.SetItemText(nItem, 3, strPath); } int CTest6Dlg::GetIconIndex(LPCTSTR lpszPath, BOOL bIsDir, BOOL bSelected) { SHFILEINFO sfi; memset(&sfi, 0, sizeof(sfi)); if (bIsDir) { SHGetFileInfo(lpszPath, FILE_ATTRIBUTE_DIRECTORY, &sfi, sizeof(sfi), SHGFI_SMALLICON | SHGFI_SYSICONINDEX | SHGFI_USEFILEATTRIBUTES |(bSelected ? 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; }
22. listctrl内容进行大数据量更新时，避免闪烁
m_list.SetRedraw(FALSE); //更新内容 m_list.SetRedraw(TRUE); m_list.Invalidate(); m_list.UpdateWindow(); 或者参考
