例8.12 如何创建你自己的分割窗

import wx

app = wx.PySimpleApp(redirect=True)
frm = SplitterExampleFrame(None, "Splitter Example")
frm.SetSize((600,500))
frm.Show()
app.SetTopWindow(frm)
app.MainLoop()

平台vista 32
idle,python2.5
运行报错,何故?

请贴错误……

Taceback(most recent call last):
File "此脚本" line 97, in <module>
frm = SplitterExampleFrame(None, 'Splitter Example')
File "此脚本" line 6, in __init__
self.MakeMenuBar()
File "此脚本" line 29, in
MakeMenuBar
self.Bind(wx.Evt_Update_UI, self.OnCheckCanSplit, item)
AttributeError:'module' object has no attribute
'EVT_Update_UI'

说是没有 EVt_Update_UI的属性.囧

原来是'EVT_Update_UI'这个要大写.......
全部改成
'EVT_UPDATE_UI'
就ok了.
