使用PyGObject中的GtkSourceView从Glade加载GUI

Question

我正在尝试使用在PyGObject中具有GtkSourceView小部件的Glade文件.我已经写了一篇关于如何在Glade中使用新的GtkSourceView 3.0的小指南:http://cjenkins.wordpress.com/2012/05/08/use-gtksourceview-widget-in-glade/

问题是当我想从PyGObject加载Glade时:

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

当我运行该文件时,我收到此错误:

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'

Glade文件(test.glade)只是一个带有GtkSourceView小部件的窗口:

<?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>

现在我不知道如何解决这个问题.我想在调用add_from_file()之前我需要注册一些类型,不是吗？欢迎任何想法.

我正在使用:

• Ubuntu Precise 12.04
• 格莱德3.12.0
• libgtksourceview 3.0
• Gtk + 3.0

亲切的问候

我想通了:DI只需要在调用add_from_file()之前在GObject中注册新类型,因为我怀疑.只需要在gi.repository的导入中添加GObject并调用type_register(),如下所示:

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

我将使用此信息更新页面.
