Moving python code to separate file

I'm having trouble moving my functions into a separate file as they access a wxpython gui. The functions are from "onSaveMovieFile" to "LogThis"

PS: I fixed it, all I did was put the function in a different file, imported it, and replaced some "self's" with the name of the different file

I see you are using wxglade for the design of you gui. The best procedure is to keep the code from glade untouched in a file. Then you import and subclass the wxglade created class in a new file. There you write all your Bind() and functions there.

For example suposse this is your wxglade autogenerated file:

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

Then in your application:

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()
