MFC中ListControl控件的使用分类.doc

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/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) ); 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)，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. 在CListCtrl显示文件，并根据文件类型来显示图标 添加listctrl控件的LVN_ITEMCHANGED消息相应函数 BOOL CTest6Dlg:OnInitDialog()CDialog:OnInitDialog();HIMAGELIST himlSmall;HIMAGELIST himlLarge;SHFILEINFO sfi;char cSysDirMAX_PATH;CString strBuf;memset(cSysDir, 0, MAX_PATH);GetWindowsDirectory(cSysDir, MAX_PATH);strBuf = cSysDir;sprintf(cSysDir, %s, strBuf.Left(strBuf.Find()+1);himlSmall = (HIMAGELIST)SHGetFileInfo (LPCSTR)cSysDir, 0, &sfi,sizeof(SHFILEINFO), SHGFI_SYSICONINDEX | SHGFI_SMALLICON );himlLarge = (HIMAGELIST)SHGetFileInfo(LPCSTR)cSysDir, 0, &sfi, sizeof(SHFILEINFO), SHGFI_SYSICONINDEX | SHGFI_LARGEICON);if (himlSmall & himlLarge):SendMessage(m_list.m_hWnd, LVM_SETIMAGELIST,(WPARAM)LVSIL_SMALL, (LPARAM)himlSmall);:SendMessage(m_list.m_hWnd, LVM_SETIMAGELIST,(WPARAM)LVSIL_NORMAL, (LPARAM)himlLarge);return TRUE; / return TRUE unless you set the focus to a controlvoid CTest6Dlg:AddFiles(LPCTSTR lpszFileName, BOOL bAddToDocument)int nIcon = GetIconIndex(lpszFileName, FALSE, FALSE);CString strSize;CFileFind filefind;/ get file sizeif (filefind.FindFile(lpszFileName)filefind.FindNextFile();strSize.Format(%d, filefind.GetLength();elsestrSize = 0;/ split path and filenameCString strFileName = lpszFileName;CString strPath;int nPos = strFileName.ReverseFind();if (nPos != -1)strPath = strFileName.Left(nPos);strFileName = strFileName.Mid(nPos + 1);/ insert to listint nItem = m_list.GetItemCount();m_list.InsertItem(nItem, strFileName, nIcon);m_list.SetItemText(nItem, 1, strSize);m_list.SetItemText(nItem, 2, strFileName.Right(3);m_list.SetItemText(nItem, 3, strPath);int CTest6Dlg:GetIconIndex(LPCTSTR lpszPath, BOOL bIsDir, BOOL bSelected)SHFILEINFO sfi;memset(&sfi, 0, sizeof(sfi);
