Hi Everyone,
I am currently working on a GUI in wxglade (using wxpython of course), and I am trying to work out the best way to get it so that when a button is clicked, it triggers something in another python file. Basically the following
gui.py
import wx
#all the wx python code
#upon a button click, runs clicked() in main.py
main.py
import gui.py
start GUI
def clicked():
#runs when button is clicked.
Also, is it possible to then update the GUI from main.py based on the output of the function. I have been trying to work this out for ages -> from a simple example of how to do this I should be able to work out what to do from then on. I want to keep the backend and GUI sepearte so it is really easy to alter the GUI.
Thanks for any help!

import main.py
in your GUI code. Instantiate the necessary objects, then call the
required backend functionality in the event handlers for the button or
menu or choice or whatever widget.
very pseudo code guaranteed not to run...
import backend
class MyFrame(wx.Frame):
def __init__(self):
self.btn = wx.Button(self, label="DoSomething")
self.btn.Bind(wx.EVT_BUTTON, self.do_something)
def do_something(self, event):
wx.GetApp().be.method_to_do_something()
class MyApp(wx.App):
def OnInit(self):
self.be = backend.core_class()
self.frame = MyFrame(None, title="Frontend for my backend")
self.frame.Show(True)
self.SetTopWindow(self.frame)

The pubsub module is practically designed for this very purpose. One other way to do this is something like this (some code snitched from Timothy)
<code>
#gui.py
from someFile import myHandler
self.btn = wx.Button(self, label="DoSomething")
self.btn.Bind(wx.EVT_BUTTON, myHandler)
</code>
The way it currently looks in your example could cause a recursive import. So don't do that!
