Load GUI from a polarized field using GtkSourceView in PyGObject

Question

I am trying to use a Glade file with GtkSourceView widgets in PyGObject. I wrote a little guide on how to start using the new GtkSourceView 3.0 in Glade: http://cjenkins.wordpress.com/2012/05/08/use-gtksourceview-widget-in-glade/

The problem is when I want to download this Glade from PyGObject:

from gi.repository import Gtk, GtkSource from os.path import abspath, dirname, join WHERE_AM_I = abspath(dirname(__file__)) class MyApp(object): def __init__(self): self.builder = Gtk.Builder() self.glade_file = join(WHERE_AM_I, 'test.glade') self.builder.add_from_file(self.glade_file) if __name__ == '__main__': try: gui = MyApp() Gtk.main() except KeyboardInterrupt: pass 

When I ran this file, I got this error:

 Traceback (most recent call last): File "test.py", line 15, in <module> gui = MyApp() File "test.py", line 11, in __init__ self.builder.add_from_file(self.glade_file) File "/usr/lib/python2.7/dist-packages/gi/types.py", line 43, in function return info.invoke(*args, **kwargs) gi._glib.GError: Invalid object type `GtkSourceView' 

The Glade file (test.glade) is just a window with GtkSourceView widgets in it:

 <?xml version="1.0" encoding="UTF-8"?> <interface> <!-- interface-requires gtksourceview 3.0 --> <!-- interface-requires gtk+ 3.0 --> <object class="GtkWindow" id="window1"> <property name="can_focus">False</property> <child> <object class="GtkSourceView" id="gtksourceview1"> <property name="visible">True</property> <property name="can_focus">True</property> <property name="has_tooltip">True</property> <property name="left_margin">2</property> <property name="right_margin">2</property> <property name="tab_width">4</property> <property name="auto_indent">True</property> <property name="indent_on_tab">False</property> </object> </child> </object> </interface> 

How to solve this, I do not know now. I suppose I need to register some type before calling add_from_file (), and not? Any idea is welcome.

I use:

• Ubuntu Precise 12.04
• Glade 3.12.0
• libgtksourceview 3.0
• Gtk + 3.0

I realized: D I just needed to register a new type in GObject before calling add_from_file () , as I suspected. You just need to add GObject to the import from gi.repository and call type_register () as follows:

 from gi.repository import Gtk, GtkSource, GObject from os.path import abspath, dirname, join WHERE_AM_I = abspath(dirname(__file__)) class MyApp(object): def __init__(self): self.builder = Gtk.Builder() self.glade_file = join(WHERE_AM_I, 'test.glade') GObject.type_register(GtkSource.View) self.builder.add_from_file(self.glade_file) if __name__ == '__main__': try: gui = MyApp() Gtk.main() except KeyboardInterrupt: pass 

I am updating a page with this information.
