我不知道如何向 glade/python 中的菜单项添加功能（快速生成）

Question

我正在尝试在单击时向菜单项添加一个功能我希望该功能能够执行

应用程序名为 Simpleadministration

我正在使用的代码位于 Simpleadministrationwindow.py :

## 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())

终端警告：

WARNING:simpleadministration_lib: connect_signals() 'expected handler 'on_account_add_menu_item_activate' in /home/ami/simpleadministration/simpleadministration/SimpleadministrationWindow.py'

我不知道到底出了什么问题，有人可以帮我吗？

额外信息：

（具有从 SimpleadministrationWindow.ui 中选择的项目的菜单结构） http://i57.tinypic.com/2s6pstx.png（声望低于 10 时无法上传）

尝试提供尽可能多的信息

(SimpleadministrationWindow.ui)

这现在有效，但我认为您不应该这样做，您可能不应该做的其他事情是使生成器全局化，但我不知道如何访问我的 windows 另一种方式（我可能 post 另一个问题）但我认为我的整个基础设施需要改变

我建议查看更多有关如何构建 classes 的示例。这个问题的答案包含一个工作示例，您应该能够快速将其适应您的程序：

MultiWindow error Glade, Gtk and Python

您看到的警告意味着您在 Glade 中定义的处理程序未被 builder.connect_signals(Handler()) 方法找到。所以也许 class 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提出改进建议的地方。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。
