使用Python的Glade 3无法正常工作

Question

I made a nice interface with Glade 3 for Windows 7 (v3.14.2) It should run with Python for Ubuntu 12.04

So i made this program:

#!/usr/bin/env python
# -*- coding: utf-8 -*-


import gtk
import gtk.glade

class HellowWorldGTK:

        def __init__(self):
                self.gladefile = "userInput.glade" 
                self.glade = gtk.Builder()
                self.glade.add_from_file(self.gladefile)
                self.glade.connect_signals(self)
                self.glade.get_object("mainWindow").show_all()

        def on_MainWindow_delete_event(self, widget, event):
                gtk.main_quit()

if __name__ == "__main__":
        try:
                a = HellowWorldGTK()
                gtk.main()
        except KeyboardInterrupt:
                pass

and, when running in Ubuntu, this is what the console says:

aimc@ubuntu:~/Desktop$ python main_ex.py 
main_ex.py:13: GtkWarning: Unknown property: GtkWindow.margin-left
  self.glade.add_from_file(self.gladefile)
main_ex.py:13: GtkWarning: Unknown property: GtkWindow.margin-right
  self.glade.add_from_file(self.gladefile)
main_ex.py:13: GtkWarning: Unknown property: GtkWindow.margin-top
  self.glade.add_from_file(self.gladefile)
main_ex.py:13: GtkWarning: Unknown property: GtkWindow.margin-bottom
  self.glade.add_from_file(self.gladefile)
main_ex.py:13: Warning: cannot create instance of abstract (non-instantiatable) type `GtkPaned'
  self.glade.add_from_file(self.gladefile)
Segmentation fault (core dumped)

What is wrong with my .glade file? Should I use other Glade version? I would really appreciate your help.

Answer 1

您可能在Windows和Ubuntu上具有不同的，不兼容的GTK版本。

Answer 2

我再次尝试了Glade3.8（可在官方网站上找到较早的版本），它与上面编写的代码兼容，并且还提供了功能更丰富的RAD工具。
