wxPython - ListCrtl和SQLite3

Question

我想获得一个SQLite3数据库来填充一个wx.ListCrtl。我可以把它打印到标准输出/标准错误没有任何问题。我似乎无法弄清楚如何在DataWindow/DataList中显示数据？我敢肯定，我犯了一些代码错误，所以任何帮助表示赞赏。

Main.py

import wx 
import wx.lib.mixins.listctrl as listmix 
from database import * 
import sys 

class DataWindow(wx.Frame): 
    def __init__(self, parent = None): 
     wx.Frame.__init__(self, parent, -1, 'DataList', size=(640,480)) 
     self.win = DataList(self) 
     self.Center() 
     self.Show(True) 

class DataList(wx.ListCtrl, listmix.ListCtrlAutoWidthMixin, listmix.ColumnSorterMixin): 
    def __init__(self, parent = DataWindow): 
     wx.ListCtrl.__init__(self, parent, -1, style=wx.LC_REPORT|wx.LC_VIRTUAL|wx.LC_HRULES|wx.LC_VRULES) 

     #building the columns 
     self.InsertColumn(0, "Location") 
     self.InsertColumn(1, "Address") 
     self.InsertColumn(2, "Subnet") 
     self.InsertColumn(3, "Gateway") 
     self.SetColumnWidth(0, 100) 
     self.SetColumnWidth(1, 150) 
     self.SetColumnWidth(2, 150) 
     self.SetColumnWidth(3, 150) 

class MainWindow(wx.Frame): 
    def __init__(self, parent = None, id = -1, title = "MainWindow"): 
     wx.Frame.__init__(self, parent, id, title, size = (800,600), 
          style = wx.DEFAULT_FRAME_STYLE^(wx.RESIZE_BORDER)) 

     # StatusBar 
     self.CreateStatusBar() 

     # Filemenu 
     filemenu = wx.Menu() 

     # Filemenu - About 
     menuitem = filemenu.Append(-1, "&About", "Information about this application") 
     self.Bind(wx.EVT_MENU, self.onAbout, menuitem) 

     #Filemenu - Data 
     menuitem = filemenu.Append(-1, "&Data", "Get data") 
     self.Bind(wx.EVT_MENU, self.onData, menuitem) 
     # Filemenu - Seperator 
     filemenu.AppendSeparator() 

     #Filemenu - Exit 
     menuitem = filemenu.Append(-1, "&Exit", "Exit the application") 
     self.Bind(wx.EVT_MENU, self.onExit, menuitem) 

     # Menubar 
     menubar = wx.MenuBar() 
     menubar.Append(filemenu, "&File") 
     self.SetMenuBar(menubar) 

     # Show 
     self.Show(True) 
     self.Center() 

    def onAbout(self, event): 
     pass 

    def onData(self, event): 
     DataWindow(self) 
     callDb = Database() 
     sql = "SELECT rowid, address, subnet, gateway FROM pod1" 
     records = callDb.select(sql) 
     for v in records: 
      print "How do I get the records on the DataList?" 
      #print "%s%s%s" % (v[1],v[2],v[3]) 
      #for v in records: 
      #DataList.InsertStringItem("%s") % (v[0], v[1], v[2]) 

    def onExit(self, event): 
     self.Close() 
     self.Destroy() 

    def onSave(self, event): 
     pass 

if __name__ == '__main__': 
    app = wx.App() 
    frame = MainWindow(None, -1) 
    frame.Show() 
    app.MainLoop() 

database.py

import os 
import sqlite3 

class Database(object): 

    def __init__(self, db_file="data/data.sqlite"): 
     database_allready_exists = os.path.exists(db_file) 
     self.db = sqlite3.connect(db_file) 
     if not database_allready_exists: 
      self.setupDefaultData() 

    def select(self,sql): 
     cursor = self.db.cursor() 
     cursor.execute(sql) 
     records = cursor.fetchall() 
     cursor.close 
     return records 

    def insert(self,sql): 
     newID = 0 
     cursor = self.db.cursor() 
     cursor.execute(sql) 
     newID = cursor.lastrowid 
     self.db.commit() 
     cursor.close() 
     return newID 

    def save(self,sql): 
     cursor = self.db.cursor() 
     cursor.execute(sql) 
     self.db.commit() 
     cursor.close() 

    def setupDefaultData(self): 
     pass

我不喜欢这样。我甚至不知道为什么，我只是复制从演示代码（大约），该文档是不是很清楚：

count = 0 
    for v in records: 
     index = DataList.InsertStringItem(sys.maxint, str(count + 1)) 

     DataList.SetStringItem(index, 0, v['rowid']) 
     DataList.SetStringItem(index, 1, v['address']) 
     count += 1 

的数量是对列的引用来设置该字符串。真的不确定索引，说实话
