以下未经说明，listctrl默认view 风格为report ------------------------------------------------------------------------------- 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<m_list.GetItemCount(); 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<m_list.GetItemCount(); 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 <a href="http://support.microsoft.com/kb/173242/en-us" target="_blank">http://support.microsoft.com/kb/173242/en-us</a> -------------------------------------------------------------------------------- 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; } <div> 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; -------------------------------------------------------------------------------- 17. 得到另一个进程里的listctrl控件的item内容 <a href="http://www.codeproject.com/threads/int64_memsteal.asp" target="_blank">http://www.codeproject.com/threads/int64_memsteal.asp</a> -------------------------------------------------------------------------------- 18. 选中listview中的item Q131284: How To Select a Listview Item Programmatically <a href="http://support.microsoft.com/kb/131284/en-us" target="_blank">http://support.microsoft.com/kb/131284/en-us</a> -------------------------------------------------------------------------------- 19. 如何在CListView中使用CListCtrl的派生类 <a href="http://www.codeguru.com/cpp/controls/listview/introduction/article.php/c919/" target="_blank">http://www.codeguru.com/cpp/controls/listview/introduction/article.php/c919/</a> -------------------------------------------------------------------------------- 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 </div>
