在Python-tkinter中选择后立即在框架中获取选项菜单的选择

问题描述

我正在尝试将菜单中的选定选项打印到框架（显示为log_Box），但是找不到在框架中显示动作的方法。我的菜单选项代码...

from tkinter import *
import tkinter as tk

# Creating window object
window = Tk()
window.title("Windows App")
window.configure(bg="#263D42")
window.geometry("700x400")

# Menubar
def DummyActions():
    '''
    :return: list of actions,where each action is a tuple whose first element is the new node and the second element is
    the mode of transportation to be used to reach the node
    '''
    import random
    coin_flip = random.random()
    if coin_flip >= 0.5:
        return [(38,'B'),(78,'T'),(108,'U')]
    else:
        return [(48,(58,(68,'U')]

if __name__ == '__main__' :

    print('Running assignment dummy APIs')
    options = []
    for action in DummyActions():
        options.append(action)
        option = action

menubar = Menu(window)

menuOptions = options
menu = Menu(menubar,tearoff = 0)
menubar.add_cascade(label ='Menu',menu = menu)
for opt in menuOptions:
    menu.add_command(label = opt,command = None) 
    menu.add_separator()

window.config(menu = menubar)

#Log Box - display all actions
log_Box = Frame(window,bg="#f0e4ea")
log_Box.place(relwidth=0.9,relheight=0.8,relx=0.05,rely=0.1)
label = Label(log_Box,text="Log Box",pady=2,bg="gray")
label.pack()

window.mainloop()
