I've created a simple helper class for Glade, a widget designer for the crossplatform GTK toolkit:

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

class GladeApplication:
   def __init__(self, glade_file):
      class Widgets:
         def __init__(self, glade):
            self._glade = glade
         def __getattr__(self, name):
            return self._glade.get_widget(name)
      
      self._glade = gtk.glade.XML(glade_file)
      self._glade.signal_autoconnect(self)
      self.widget = Widgets(self._glade)

This class puts all the widgets defined by Glade in "self.widgets", and looks for events in the main class.

For instance, to test this I created a simple ROT13 application that consists of a window, a textview widget, and a button widget. In Glade I setup the window's destroy event to point to "on_destroy", and the button clicked event to point to "on_button_clicked". I saved the glade XML file as "rot13.glade".

The python code to use this:

(Toggle Plain Text)

class Rot13(GladeApplication):
   def __init__(self):
      GladeApplication.__init__(self, "rot13.glade")

   def on_destroy(self, window):
      gtk.main_quit()

   def on_button_clicked(self, button):
      text_buffer = self.widget.textview.get_buffer()
      text = text_buffer.get_text(*text_buffer.get_bounds())
      text_buffer.set_text(text.encode('rot13'))

Rot13()
gtk.main()

Arevos, pygtk and Glade sound interesting. I have tried to play with it before, but got lost in the files to download. Could you please give a list of all the files one needs and where to get them?

I am using Windows XP.

Thank you!

Well, I'm on linux so installing PyGTK/Glade fairly straightforward (apt-get handles all of the hard stuff).

Under Windows, I believe you can download PyGTK 2.6 from here and the GTK Windows development environment from here, and I suspect you should be set.

Thank you,
I got pygtk/gtk to work.

Now I need to know a little more about glade/gnome and I will be set.

Glade is a graphical GUI builder for the GTK toolkit. You can build up an interface, and connect predefined events to custom hooks (for instance, connecting the button-clicked event to "on_button_clicked"). Glade saves the interface as XML, which can then be loaded up by PyGTK.

Gnome is a desktop environment for Linux that uses the GTK toolkit. Glade was developed for the Gnome project, though Gnome is not required for Glade to run; only GTK is needed.

I need to look into this when i have some spare time, I'm pretty bogged down with coursework etc. But when i can i'll download pyGTK and have a go. I already have Glade though.

Thank you Arevos,
that explains your Glade helper class.
