pyGTK格林德警告丢失处理程序

Question

我想处理菜单点击事件，但是， 这个丢失的处理程序警告正在发生， 我在哪里错了？ 即时连接信号ab与处理器abcd on menuitem6，在激活事件， 它是否正确处理点击事件？
这里是错误：

abc.py:15: RuntimeWarning: missing handler 'a 
bc' 
builder.connect_signals({ "on_window_destroy" : gtk.main_quit }) 
None 

这里的代码：

abc.py：

pygtk.require("2.0")

     s = model.get_string_from_iter(iter)

     obj = mymodel.get_value(niter, 0) 
     cell.set_property('text', obj)

Answer 1

您可以使用builder.connect_signals(self)。然后你只需要在你的xml文件中创建类似于处理程序的方法。所以在这种情况下：

class TutorialApp(object): 
    def __init__(self): 
     builder = gtk.Builder() 
     builder.add_from_file('./tutorial.xml') 
     builder.connect_signals(self) 
     self.window = builder.get_object('disasm') 
     ##rest of you __init__ 

    def abc(self, menuitem): 
     print "tst" 

    def on_window_destroy(self, window): 
     gtk.main_quit()
