这是我编辑并尝试工作的当前代码,但仍然无法正常工作:/调试帮助会很棒:)它会给出错误,变量“self”和“parent”没有定义在mainWindow类,以及“class mainWindow”行的错误。不完全确定它们的含义或如何修复

MenuBar的第一个参数是指定MenuBar所属的父窗口。您收到错误,因为您没有定义它。如果MenuBar是顶级窗口小部件,只需将其链接到根目录:

root = Tk()
menuBar = Pmw.MenuBar(root,
    hull_relief = 'raised',
    hull_borderwidth = 1,
    balloon = self.balloon)
menuBar.pack(fill = 'x')

root.mainloop()

您应该发布所有代码和确切的错误消息,以便我可以提供更好的帮助,但是根据您发布的内容,您的问题似乎是:

class foo:

是空的。所以你需要它看起来像

class foo:
    pass

为了不出错。

未定义父级可能是因为您从未定义变量父级,因此您可能需要以下内容:

parent = Tkinter.Tk()
