运行时错误缺少处理程序python glad

Question

这是我的一段代码

class gui_manage():
    def delete_event(self , widget , data):
        False
        print 'delete'
    # #######################
    # define some functions here
     as example : start_download(self ,widget)
    ########################################
    def start_download( self , widget  ):
        print 'add_url_clicked'

    def __init__(self):
        builder = gtk.Builder()
        builder.add_from_file('gui.glade')
        win=builder.get_object('add_url_win')
        text_entry= builder.get_object('url_entry')
        signals ={ 
         'delete_event' : self.delete_event , 
         'destroy' : self.destroy  ,
         'cancel_button_clicked' : self.delete_event , 
         'addpaused_button_clicked' : self.addpaused ,
     'start_download_clicked' : self.start_download , 
         'addpaused_button_clicked' : self.addpaused 
         }
        builder.connect_signals(signals)

glade文件显示了相应的行：

^{pr2}$

我得到了一个错误：

gui_manage.py:45: RuntimeWarning: missing handler 'start_download'
  builder.connect_signals(signals)

但是，被单击的“取消按钮的事件”调用的delete_event()方法成功。在

简言之，所有的方法都是用同样的方式定义的，连接在同一个字典中，虽然有些是缺失的！在

Answer 1

现在效果很好：

'def start_download( self , object  ):
    print 'add_url_clicked''

而不是

^{pr2}$

&

'self.signals = {}'

而不是

'signals = {}'

&

'self.builder.connect_signals(self)'

而不是

'self.builder.connect_signals(signals)'
