python实例代码之禁用菜单

python实现禁用菜单的功能，代码如下：

#!/bin/python

from Tkinter import *

class TestMenu:
    def __init__(self, master):
  self.master = master
  self.menubar = Menu(self.master)

        self.radmenu = Menu(self.menubar)
        self.radmenu.add_radiobutton(label='A')
        self.radmenu.add_radiobutton(label='B')
        self.radmenu.add_radiobutton(label='C')
        self.radmenu.add_radiobutton(label='D')
        self.radmenu.add_radiobutton(label='E')
        self.radmenu.add_radiobutton(label='F')
        self.radmenu.add_radiobutton(label='H')
        self.radmenu.add_radiobutton(label='L')
        self.radmenu.add_radiobutton(label='Z')

        self.menubar.add_cascade(label="Radiobutton Menu", menu=self.radmenu)

        self.menubar.entryconfig(1, state=disabled)
  self.top = Toplevel(menu=self.menubar, width=500, relief=RAIsed,
                            borderwidth=2)

def main():
    root = Tk()
    root.withdraw()
    app = TestMenu(root)
    root.mainloop()

if __name__ == '__main__':
    main()
