python messagebox彈窗退出_如何處理Tkinter的關閉視窗事件？

下面是一個在Windows 7上測試的工作示例：# Python 3

import tkinter

import tkinter.scrolledtext as scrolledtext

class GUI(object):

def __init__(self):

root = self.root = tkinter.Tk()

root.title('Test')

# make the top right close button minimize (iconify) the main window

root.protocol("WM_DELETE_WINDOW", root.iconify)

# make Esc exit the program

root.bind('', lambda e: root.destroy())

# create a menu bar with an Exit command

menubar = tkinter.Menu(root)

filemenu = tkinter.Menu(menubar, tearoff=0)

filemenu.add_command(label="Exit", command=root.destroy)

menubar.add_cascade(label="File", menu=filemenu)

root.config(menu=menubar)

# create a Text widget with a Scrollbar attached

txt = scrolledtext.ScrolledText(root, undo=True)

txt['font'] = ('consolas', '12')

txt.pack(expand=True, fill='both')

gui = GUI()

gui.root.mainloop()
