Question

I have two modules like this (very very simplified):

main.py:

from window import *

class MyApp(wx.Frame):

    def __init__(self, parent, label, pos, size):
        wx.Frame.__init__(self, parent = parent, title = label, pos = pos, size = size) 
        self.Centre()
        create_window(self)
        self.Bind(wx.EVT_CLOSE, self.OnClose)

    def OnClose(self, event):
        self.dlg = wx.MessageDialog(self, 'Quit application', 
            'Please confirm', wx.YES_NO | wx.NO_DEFAULT | wx.ICON_QUESTION)
        if self.dlg.ShowModal() == wx.ID_YES:
            self.Destroy()

if __name__ == '__main__':
    app = wx.App()
    frame = MyApp(None, 'MyApp', (0, 0), (740, 640))
    frame.Show()
    frame.SetFocus()
    app.MainLoop()

window.py:

import wx            

def create_window(self):

    self.menubar = wx.MenuBar()
    self.fileMenu = wx.Menu()

    self.item = self.fileMenu.Append(wx.ID_EXIT, 'Quit', 'Quit application')

    self.Bind(wx.EVT_MENU, self.OnClose, self.item)

    self.menubar.Append(self.fileMenu, '&File')
    self.SetMenuBar(self.menubar)

    self.statusbar = self.CreateStatusBar()
    self.statusbar.SetStatusText('Ready')

Now i would like to move the OnClose method from main.py to window.py (not only this one, if have many other methods in main.py, and I want to move all of them to different modules to make my code more structured).
But just cutting the module from main.py and pasting it in window.py doesn’t work (as a was expecting).
So, my question is, what do I have to change in my code to make an event method or another method accessible from another module?

Answer 1

I am not sure what you want. If this is about general behavior you want to implement in your classes (like a particular way of closing them, report state, adding a balloontip system, etc), then one way is to create a class with the corresponding methods and to inherit from her.

class BehaviorPack(object):
    def __init__(self):
        whatever
    def OnClose(self, event)
        whatever
    def colour_panel(self):
        whatever

then you import that class and inherit from it:

class MyFrame(wx.Frame, BehaviorPack):
    def __init__(self, *args, **kargs):
        ..........
