MFC CListCtrl的用法详解.docx

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_InsertColumn1. 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itemLVS_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stylelStyle &= LVS_TYPEMASK; /清除显示方式位lStyle |= LVS_REPORT; /设置styleSetWindowLong(m_list.m_hWnd, GWL_STYLE, lStyle);/设置styleDWORD 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_SHOWSELALWAYS5. 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);elsewhile (pos)int nItem = m_list.GetNextSelectedItem(pos);TRACE1(Item %d was selected!n, nItem);/ you could do your own processing on nItem here8. 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-us9. 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 hereCString 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.asp18. 选中listview中的itemQ131284: How To Select a Listview Item Programmatically/kb/131284/en-us19. 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);m_list.SetItem(.);
