（六）ListCtrl列表控件的使用示例
ListCtrl这个控件比较强大，是我比较喜欢使用的控件之一。
下面是list_report.py中提供的简单用法：

import wx
import sys, glob, random
import data

class DemoFrame(wx.Frame):
  def __init__(self):
    wx.Frame.__init__(self, None, -1,
             "wx.ListCtrl in wx.LC_REPORT mode",
             size=(600,400))

    il = wx.ImageList(16,16, True)
    for name in glob.glob("smicon??.png"):
      bmp = wx.Bitmap(name, wx.BITMAP_TYPE_PNG)
      il_max = il.Add(bmp)
    self.list = wx.ListCtrl(self, -1, style=wx.LC_REPORT)
    self.list.AssignImageList(il, wx.IMAGE_LIST_SMALL)

    # Add some columns
    for col, text in enumerate(data.columns):
      self.list.InsertColumn(col, text)

    # add the rows
    for item in data.rows:
      index = self.list.InsertStringItem(sys.maxint, item[0])
      for col, text in enumerate(item[1:]):
        self.list.SetStringItem(index, col+1, text)

      # give each item a random image
      img = random.randint(0, il_max)
      self.list.SetItemImage(index, img, img)
        
    # set the width of the columns in various ways
    self.list.SetColumnWidth(0, 120)
    self.list.SetColumnWidth(1, wx.LIST_AUTOSIZE)
    self.list.SetColumnWidth(2, wx.LIST_AUTOSIZE)
    self.list.SetColumnWidth(3, wx.LIST_AUTOSIZE_USEHEADER)


app = wx.PySimpleApp()
frame = DemoFrame()
frame.Show()
app.MainLoop()
