我正在尝试使用在 PyGObject 中具有 GtkSourceView 小部件的 Glade 文件。我写了一个关于如何开始在 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,出现此错误:
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>
我现在不知道如何解决这个问题。我想我需要在调用 add_from_file() 之前注册某种类型,不是吗?欢迎任何想法。
我正在使用:
- Ubuntu 精确 12.04
- 林间空地 3.12.0
- libgtksourceview 3.0
- gtk+ 3.0
亲切的问候
