CListCtrl_使用技巧.doc

可以创建一个EditBox,平时隐藏,当双击(或者其他事件)发生在某一单元格时,将它显示出来- 取原有单元格内容显示- 修改- (回车转移焦点等事件发生后)更新原有单元格内容- 隐藏.当你双击的时候，在选中的item的区域动态创建一个EDIT，在失去焦点时destroy这个edit就可以了。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 /library/default.asp?url=/library/en-us/wceshellui5/html/wce50lrflistviewstyles.asp3. 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; im_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; 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) );

*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);

This means that the system expects you to fill in the image index when you get an LVN_GETDISPINFO notification. Inside of the handler for LVN_GETDISPINFO, you can check if the item is selected and set the appropriate image index.
