python实例代码之菜单工具栏

python实现菜单工具栏，代码如下：

#!/bin/python
from Tkinter import *
from tkMessageBox import *

class NewMenuDemo(Frame):
    def __init__(self, parent=None):
        Frame.__init__(self, parent)
        self.pack(expand=YES, fill=BOTH)
        self.createWidgets()
        self.master.title("Toolbars and Menus")
        self.master.iconname("tkpython")

    def createWidgets(self):
        self.makeMenuBar()
        self.makeToolBar()
        L = Label(self, text='Menu and Toolbar Demo')
        L.config(relief=SUNKEN, width=40, height=10, bg='white')
        L.pack(expand=YES, fill=BOTH)

    def makeToolBar(self):
        toolbar = Frame(self, cursor='hand2', relief=SUNKEN, bd=2)
        toolbar.pack(side=BOTTOM, fill=X)
        Button(toolbar, text='Quit',  command=self.quit    ).pack(side=RIGHT)
        Button(toolbar, text='Hello', command=self.greeting).pack(side=LEFT)

    def makeMenuBar(self):
        self.menubar = Menu(self.master)
        self.master.config(menu=self.menubar)
        self.fileMenu()
        self.editMenu()
#        self.imageMenu()

    def fileMenu(self):
        pulldown = Menu(self.menubar)
        pulldown.add_command(label='Open...', command=self.notdone)
        pulldown.add_command(label='Quit',    command=self.quit)
        self.menubar.add_cascade(label='File', underline=0, menu=pulldown)

    def editMenu(self):
        pulldown = Menu(self.menubar)
        pulldown.add_command(label='Paste',   command=self.notdone)
        pulldown.add_command(label='Spam',    command=self.greeting)
        pulldown.add_separator()
        pulldown.add_command(label='Delete',  command=self.greeting)
        pulldown.entryconfig(4, state=DISABLED)
        self.menubar.add_cascade(label='Edit', underline=0, menu=pulldown)

#    def imageMenu(self):
#        photoFiles = ('guido.gif', 'java2s.gif', 'java2s.gif')
#        pulldown = Menu(self.menubar)
#        self.photoObjs = []
#        for file in photoFiles:
#            img = PhotoImage(file='../gifs/' + file)
#            pulldown.add_command(image=img, command=self.notdone)
#            self.photoObjs.append(img)   # keep a reference
#        self.menubar.add_cascade(label='Image', underline=0, menu=pulldown)

    def greeting(self):
        showinfo('greeting', 'Greetings')
    def notdone(self):
        showerror('Not implemented', 'Not yet available')
    def quit(self):
        if askyesno('Verify quit', 'Are you sure you want to quit?'):
            Frame.quit(self)

if __name__ == '__main__':  NewMenuDemo().mainloop()  # if I'm run as a script

效果图，如下：
