ListControl使用范例.doc

MFC如何使用 List Control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-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); nbsp; 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 szBuf1024; 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 /kb/173242/en-us-9. 得到listctrl的所有列的header字符串内容 LVCOLUMN lvcol; char str256; int nColNum; CString strColumnName4;/假如有4列 nColNum = 0; lvcol.mask = LVCF_TEXT; lvcol.pszText = str; lvcol.cchTextMax = 256; while(m_list.GetColumn(nColNum, &lvcol) strColumnNamenColNum = 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; nbsp; 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; -17. 得到另一个进程里的listctrl控件的item内容/threads/int64_memsteal.asp-18. 选中listview中的itemQ131284: How To Select a Listview Item Programmatically/kb/131284/en-us-19. 如何在CListView中使用CListCtrl的派生类/cpp/controls/listview/introduction/article.php/c919/-20. listctrl的subitem添加图标 m_list.SetExtendedStyle(LVS_EX_SUBITEMIMAGES);
