I created a simple program using a glade .xml file and it, whenever I run the program, it crashes!

Here's the Python code:

#!/usr/bin/env python

import pygtk
pygtk.require("2.0")
import gtk

class TutorialApp(object):
    def __init__(self):
        builder = gtk.Builder()
        builder.add_from_file("tutorial.xml")
        builder.connect_signals({ "on_window_destroy" : gtk.main_quit })
        self.window = builder.get_object("window")
        self.window.show()

if __name__ == "__main__":
    app = TutorialApp()
    gtk.main()

The .xml file is rather extensive, so I can't post it in a readable form, but here it is.

Maybe I can get help, if not I'll continue trying to debug it on my own.

Do you get any error message? –  Florian Diesch May 7 '13 at 0:44
    
Nope, it just crashes. –  RPi Awesomeness May 7 '13 at 0:46

You problem is that you're mixing a GTK3 interface with old PyGTK (GTK2) Python code.

Here's the ported code:

#!/usr/bin/env python

from gi.repository import Gtk

class TutorialApp(object):
    def __init__(self):
        builder = Gtk.Builder()
        builder.add_from_file("tutorial.xml")
        builder.connect_signals({ "on_window_delete_event" : Gtk.main_quit })
        self.window = builder.get_object("window")
        self.window.show()

if __name__ == "__main__":
    app = TutorialApp()
    Gtk.main()

See the PyGObject wikipage for more information.

I also had to change two things in your Glade file:

  1. Renamed the window widget from window1 to window
  2. Defined the delete-event handler of the window

Here's the full file:

<?xml version="1.0" encoding="UTF-8"?>
<interface>
  <!-- interface-requires gtk+ 3.0 -->
  <object class="GtkWindow" id="window">
    <property name="can_focus">False</property>
    <signal name="delete-event" handler="on_window_delete_event" swapped="no"/>
    <child>
      <object class="GtkBox" id="box1">
        <property name="visible">True</property>
        <property name="can_focus">False</property>
        <property name="orientation">vertical</property>
        <child>
          <object class="GtkMenuBar" id="menubar1">
            <property name="visible">True</property>
            <property name="can_focus">False</property>

              <object class="GtkMenuItem" id="menuitem1">

Thanks for formatting my code in my question for me, I should have taken a little longer and done that myself. Only thing is, when I try to run the program I get this error: Traceback (most recent call last): File "/home/nate/Documents/Programming/Glade (GUI)/tutorial.py", line 3, in <module> from gi.repository import Gtk ImportError: No module named gi.repository –  RPi Awesomeness May 7 '13 at 17:11
    
Alright! It works! Thanks Timo! I just had to run it within Python 2.7 instead of 3.2, duh... Thanks again! –  RPi Awesomeness May 7 '13 at 17:58
    
No problem! Python 3 should work as well, just make sure you have the correct packages installed. My guess is you're missing python3-gi. –  Timo May 7 '13 at 18:57
