我正在 Tkinter 中构建一个 GUI 作为我的应用程序的一部分，并且我编写了一个类“XMLMenu”，它是“Menu”的子类，但是当我尝试打包它时收到一个 TclError。这是它的样子：

class XMLMenu(Menu):
    def __init__(self,master,text, **kw):
        Menu.__init__(self,master, kw)
        #Irrelevent code in which I read an XML file to build the menu
        self.pack(side=TOP,fill=X)

我收到以下错误：

Traceback (most recent call last):
  File "E:\Portable Python 2.7.3.1\App\lib\threading.py", line 551, in __bootstrap_inner
    self.run()
  File "E:\Portable Python 2.7.3.1\App\lib\threading.py", line 504, in run

  File "xlistr\gui.py", line 62, in create
    app=constructor(root)

    self.menu=xmlMenu_by_filename(self,"xlistr/data/feMenu.xml")
  File "xlistr\gui.py", line 23, in xmlMenu_by_filename
    return XMLMenu(master,read_file(filename))
  File "xlistr\gui.py", line 52, in __init__
    self.pack(side=TOP,fill=X)

    + self._options(cnf, kw))

菜单不与几何管理器一起放置，而是在相应的窗口中配置：

class XMLMenu(Menu):
    def __init__(self,master,text, **kw):
        Menu.__init__(self, master, kw)
        master.config(menu=self)
        # ...
