PS：我修复了它，我所做的只是把函数放在一个不同的文件中，导入它，并用一个不同文件的名称替换一些“self”，
答案 0 :(得分：2)
我看到你正在使用wxglade来设计你的gui。 最好的方法是保持文件中的glade代码不受影响。然后在新文件中导入和子类化wxglade创建的类。你在那里写下你所有的Bind（）和函数。
例如，这是你的wxglade自动生成的文件：
mygui.py
#!/usr/bin/env python
# -*- coding: iso-8859-15 -*-
# generated by wxGlade HG on Tue Jul 26 20:03:16 2011
import wx
# begin wxGlade: extracode
# end wxGlade
class MyFrame(wx.Frame):
def __init__(self, *args, **kwds):
# begin wxGlade: MyFrame.__init__
kwds["style"] = wx.DEFAULT_FRAME_STYLE
wx.Frame.__init__(self, *args, **kwds)
self.text_ctrl_1 = wx.TextCtrl(self, -1, "", style=wx.TE_MULTILINE)
self.__set_properties()
self.__do_layout()
# end wxGlade
def __set_properties(self):
# begin wxGlade: MyFrame.__set_properties
self.SetTitle("frame_1")
# end wxGlade
def __do_layout(self):
# begin wxGlade: MyFrame.__do_layout
sizer_1 = wx.BoxSizer(wx.VERTICAL)
sizer_1.Add(self.text_ctrl_1, 1, wx.EXPAND, 0)
self.SetSizer(sizer_1)
sizer_1.Fit(self)
self.Layout()
# end wxGlade
# end of class MyFrame
然后在你的申请中：
myaplication.py
import wx
from mygui import MyFrame
class MyApplication(MyFrame):
def __init__(self, *args, **kargs):
MyFrame.__init__(self, *args, **kargs)
##**put here all your Bind()**
#**then put all your methods here:**
def onSaveMovieFile(self, evt):
----------------
def LogThis(self, evt):
----------------
if __name__ == '__main__':
app = wx.PySimpleApp()
frame = MyApplication(None)
frame.Show()
app.MainLoop()
