【pygtk】部分组件不能显示

wfnh

我的treeview不能显示，不知道是否与类的设计与继承有关系···代码如下：
Gui类：

1. import gtk
   
2. import pygtk
   
3. class Ui(object):
   
4.     def __init__(self,glade_file = None):
   
5.         self.init(glade_file)
   
6. 
   
7.     #--初始化所需的gtk材料
   
8.     def init(self,glade_file):
   
9.         gtk.rc_parse_string('''style "default-font"\n{\nfont_name = "simsun 9"\n}\nwidget_class "*" style "default-font"\ngtk-font-name = "simsun 9"''')
   
10.         self.builder = gtk.Builder()
    
11.         self.ui_file = glade_file or 'itemSearcher.glade'
    
12.         try:
    
13.             self.gui = self.builder.add_from_file(self.ui_file)
    
14.         except Exception,e:
    
15.             print "Error:%s"%e
    
16. 
    
17.     def _get_widget(self,widget_name):
    
18.         return self.builder.get_object(widget_name)
