CListCtrl使用技巧

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 CListCtrlhttp://support.microsoft.com/kb/173242/en-us

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;}

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;}

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http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_mfc_cwnd.3a3a.setredraw.asp
