从GtkSourceView一块空地在PyGObject负荷GUI(Load GUI from a

我试图使用在PyGObject一个GtkSourceView小部件格莱德文件。我写了一篇关于如何开始使用新的GtkSourceView 3.0格莱德点指南： http://cjenkins.wordpress.com/2012/05/08/use-gtksourceview-widget-in-glade/

问题是，当我想要加载格莱德从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

当我运行该文件我得到这个错误：

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'

林间空地文件（test.glade）仅仅是一个在它GtkSourceView控件窗口：

<?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>

一个如何解决这超出了我的知识，现在。我想我需要调用add_from_file（）之前注册的一些类型，而不是？任何想法是值得欢迎的。

我正在使用：

Ubuntu的精确12.04
格莱德3.12.0
libgtksourceview 3.0
GTK + 3.0

亲切的问候

我想通了：DI只需要调用add_from_file（），我怀疑以前登记在GObject的新类型。只是需要加入的GObject从gi.repository进口和调用type_register（）是这样的：

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

我将这个信息更新页面。

亲切的问候
