我试图在单击时向菜单项添加一个函数我希望该函数执行
该应用程序名为Simpleadministration
我正在使用的代码位于Simpleadministrationwindow.py：
requiredTextField.pressForDuration:0.5()
app.menuItems[@"Select All"].tap()
app.menuItems[@"Cut"].tap()
终端警告：
## functions
class Handler:
def on_account_add_menu_item_activate():
print ("something")
builder = Gtk.Builder()
builder.add_from_file("data/ui/SimpleadministrationWindow.ui")
builder.connect_signals(Handler())
如果有人帮助我，我不确切地知道出了什么问题？
额外的inf：
（SimpleadministrationWindow.ui中所选项目的菜单结构） http://i57.tinypic.com/2s6pstx.png（无法上传信誉低于10）
尽量提供尽可能多的信息
（SimpleadministrationWindow.ui）
WARNING:simpleadministration_lib: connect_signals() 'expected handler 'on_account_add_menu_item_activate' in /home/ami/simpleadministration/simpleadministration/SimpleadministrationWindow.py'
这个现在有效，但我不认为你应该这样做，你可能不应该做的其他事情是让建设者全球化，但我不知道我是怎么做的可以用另一种方式访问我的窗口（我应该发布另一个问题），但我认为我的整个基础设施需要改变

答案 0 :(得分：0)
我建议再看一些关于如何构造类的例子。这个问题的答案包含一个工作示例，您应该能够快速地将其调整到您的程序中：
您看到的警告意味着builder.connect_signals(Handler())方法找不到您在Glade中定义的处理程序。所以也许这个类没有正确初始化（检查执行顺序？）。
如果您的项目是开源的，您可以将其上传到人们可以运行整个程序并建议改进的地方。您还可以查看this程序，了解有关如何构建更大项目的一些提示。
