Windows編程入門(8)–MFC中ListBox控制項的使用

原文連結：http://www.cnblogs.com/zuollblog/archive/2010/04/21/1716940.html

1. CListCtrl 風格 
       LVS_ICON: 為每個item顯示大表徵圖 
       LVS_SMALLICON: 為每個item顯示小表徵圖 
       LVS_LIST: 顯示一列帶有小表徵圖的item 
       LVS_REPORT: 顯示item詳細資料 
直觀的理解：windows資源管理員，"查看"標籤下的"大表徵圖，小表徵圖，列表，詳細資料 
-------------------------------------------------------------------------------- 
2. 設定listctrl 風格及擴充風格 
       LONG lStyle; 
       lStyle = GetWindowLong(m_list.m_hWnd, GWL_STYLE);//擷取當前視窗style 
       lStyle &= ~LVS_TYPEMASK; //清除顯示方式位 
       lStyle |= LVS_REPORT; //設定style 
       SetWindowLong(m_list.m_hWnd, GWL_STYLE, lStyle);//設定style 
       DWORD dwStyle = m_list.GetExtendedStyle(); 
       dwStyle |= LVS_EX_FULLROWSELECT;//選中某行使整行高亮（只適用與report風格的listctrl） 
dwStyle |= LVS_EX_GRIDLINES;//網格線（只適用與report風格的listctrl） 
dwStyle |= LVS_EX_CHECKBOXES;//item前產生checkbox控制項 
m_list.SetExtendedStyle(dwStyle); //設定擴充風格 
註：listview的style請查閱msdn       
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wceshellui5/html/wce50lrflistviewstyles.asp 
-------------------------------------------------------------------------------- 
3. 插入資料 
       m_list.InsertColumn( 0, "ID", LVCFMT_LEFT, 40 );//插入列 
       m_list.InsertColumn( 1, "NAME", LVCFMT_LEFT, 50 );

      //新插入的在上面
       int nRow = m_list.InsertItem(0, "11");// 插入行
       m_list.SetItemText(nRow, 1, "jacky");//設定其它列資料

    //新插入的資料在下面

   int nIndex = m_list.GetItemCount();
    LV_ITEM lvItem;
    lvItem.mask = LVIF_TEXT ; 
    lvItem.iItem = nIndex;     //行數
    lvItem.iSubItem = 0;
    lvItem.pszText = (char*)(LPCTSTR)strCount;   //第一列
    //在最後一行插入記錄值.
         m_list.InsertItem(&lvItem); 
    //插入其它列
    m_list.SetItemText(nIndex,1,strLat);
-------------------------------------------------------------------------------- 
4. 一直選中item 
選中style中的Show selection always，或者在上面第2點中設定LVS_SHOWSELALWAYS 
-------------------------------------------------------------------------------- 
5. 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 
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為選中狀態"), 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; i<m_list.GetItemCount(); i++) 
       { 
           if( m_list.GetItemState(i, LVIS_SELECTED) == LVIS_SELECTED ) 
           { 
                 str.Format(_T("選中了第%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的資訊 
       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); 
關於得到設定item的狀態，還可以參考msdn文章 
       Q173242: Use Masks to Set/Get Item States in ClistCtrl 
http://support.microsoft.com/kb/173242/en-us 
-------------------------------------------------------------------------------- 
9. 得到listctrl的所有列的header字串內容 
       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中一項可見，即滾動捲軸 
m_list.EnsureVisible(i, FALSE); 
-------------------------------------------------------------------------------- 
11. 得到listctrl列數 
int nHeadNum = m_list.GetHeaderCtrl()->GetItemCount(); 
-------------------------------------------------------------------------------- 
12. 刪除所有列 
方法一： 
         while ( m_list.DeleteColumn (0)) 
因為你刪除了第一列後，後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控制項的NM_CLICK訊息相應函數 
       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控制項的NM_CLICK訊息相應函數 
       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快顯功能表 
添加listctrl控制項的NM_RCLICK訊息相應函數 
       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(包括用鍵盤和滑鼠切換item時)，狀態的一些變化順序 
添加listctrl控制項的LVN_ITEMCHANGED訊息相應函數 
       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); 
           } 
           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;

       m_list.SetItem(..); //具體參數請參考msdn
