MFC中ListControl控件的使用分類.doc

1. CListCtrl 風(fēng)格 LVS_ICON: 為每個item顯示大圖標(biāo) LVS_SMALLICON: 為每個item顯示小圖標(biāo) LVS_LIST: 顯示一列帶有小圖標(biāo)的item LVS_REPORT: 顯示item詳細(xì)資料 直觀的理解：windows資源管理器，“查看”標(biāo)簽下的“大圖標(biāo)，小圖標(biāo)，列表，詳細(xì)資料”2. 設(shè)置listctrl 風(fēng)格及擴展風(fēng)格 LONG lStyle; lStyle = GetWindowLong(m_list.m_hWnd, GWL_STYLE);/獲取當(dāng)前窗口style lStyle &= LVS_TYPEMASK; /清除顯示方式位 lStyle |= LVS_REPORT; /設(shè)置style SetWindowLong(m_list.m_hWnd, GWL_STYLE, lStyle);/設(shè)置style DWORD dwStyle = m_list.GetExtendedStyle(); dwStyle |= LVS_EX_FULLROWSELECT;/選中某行使整行高亮（只適用與report風(fēng)格的listctrl） dwStyle |= LVS_EX_GRIDLINES;/網(wǎng)格線（只適用與report風(fēng)格的listctrl） dwStyle |= LVS_EX_CHECKBOXES;/item前生成checkbox控件 m_list.SetExtendedStyle(dwStyle); /設(shè)置擴展風(fēng)格 注：listview的style請查閱msdn/library/default.asp?url=/library/en-us/wceshellui5/html/wce50lrflistviewstyles.asp3. 插入數(shù)據(jù) 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”);/設(shè)置數(shù)據(jù)4. 一直選中item選中style中的Show selection always，或者在上面第2點中設(shè)置LVS_SHOWSELALWAYS5. 選中和取消選中一行 int nIndex = 0; /選中 m_list.SetItemState(nIndex, LVIS_SELECTED|LVIS_FOCUSED, LVIS_SELECTED|LVIS_FOCUSED); /取消選中 m_list.SetItemState(nIndex, 0, LVIS_SELECTED|LVIS_FOCUSED);6. 得到listctrl中所有行的checkbox的狀態(tài) 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為選中狀態(tài)), i); AfxMessageBox(str); 7. 得到listctrl中所有選中行的序號 方法一： CString str; for(int i=0; iGetItemCount();12. 刪除所有列 方法一： while ( m_list.DeleteColumn (0) 因為你刪除了第一列后，后面的列會依次向上移動。 方法二： int nColumns = 4; for (int i=nColumns-1; i=0; i-) m_list.DeleteColumn (i);13. 得到單擊的listctrl的行列號 添加listctrl控件的NM_CLICK消息相應(yīng)函數(shù) 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(單擊的是第%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(單擊的是第%d行第%d列, pNMListView-iItem, pNMListView-iSubItem); AfxMessageBox(strtemp); */ *pResult = 0; 14. 判斷是否點擊在listctrl的checkbox上 添加listctrl控件的NM_CLICK消息相應(yīng)函數(shù) 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); /判斷是否點在checkbox上 if(nFlag = LVHT_ONITEMSTATEICON) AfxMessageBox(點在listctrl的checkbox上); *pResult = 0; 15. 右鍵點擊listctrl的item彈出菜單 添加listctrl控件的NM_RCLICK消息相應(yīng)函數(shù) 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切換焦點時(包括用鍵盤和鼠標(biāo)切換)，狀態(tài)的一些變化順序 添加listctrl控件的LVN_ITEMCHANGED消息相應(yīng)函數(shù) 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顯示文件，并根據(jù)文件類型來顯示圖標(biāo) 添加listctrl控件的LVN_ITEMCHANGED消息相應(yīng)函數(shù) 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);
