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，
哪里我错了？
我将信号ab与处理程序abcd连接起来
在menuitem6上，关于激活事件，
处理点击事件是否正确？
这是错误：
abc.py:15: RuntimeWarning: missing handler 'a
bc'
builder.connect_signals({ "on_window_destroy" : gtk.main_quit })
None
这是代码：
abc.py：
import pygtk
pygtk.require("2.0")
import gtk
def inIta(col, cell, model, iter, mymodel):
s = model.get_string_from_iter(iter)
niter = mymodel.get_iter_from_string(s)
obj = mymodel.get_value(niter, 0)
cell.set_property('text', obj)

答案 0 :(得分：2)
您可以使用builder.connect_signals(self)。然后你只需要创建像xml文件中的处理程序一样的方法。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()
