tkinterチェックボックスの問題を解決するには？

Question

私はpython（2.7）Cafe Systemを作ろうとしています。チェックボタンをクリックして項目を開くと、ほとんどの関数が作成されました。チェックボックスボタンをクリックすると、誰もその理由を知ることができません。

from Tkinter import * 
import random 
import time 
import datetime 

root = Tk() 
root.geometry("1350x750+0+0") 
root.title("Cafe Management System") 
root.configure(background='black') 

Tops = Frame(root, width=1350, height=100, bd=14, relief="raise") 
Tops.pack(side=TOP) 

f1 = Frame(root, width=900, height=650, bd=8, relief="raise") 
f1.pack(side=LEFT) 

f2 = Frame(root, width=440, height=650, bd=8, relief="raise") 
f2.pack(side=RIGHT) 

f1a = Frame(f1, width=900, height=320, bd=6, relief="raise") 
f1a.pack(side=TOP) 

f2a = Frame(f1, width=900, height=320, bd=6, relief = "raise") 
f2a.pack(side=BOTTOM) 

ft2 = Frame(f2, width= 440,height=450,bd=12,relief="raise") 
ft2.pack(side=TOP) 
fb2 = Frame(f2, width=440, height=250, bd=16, relief="raise") 
fb2.pack(side=BOTTOM) 

f1aa = Frame(f1a, width=400, height=330, bd=16, relief="raise") 
f1aa.pack(side=LEFT) 
f1ab = Frame(f1a, width=400, height=330, bd=16, relief="raise") 
f1ab.pack(side=RIGHT) 

f2aa = Frame(f2a, width=450, height=330, bd=14, relief="raise") 
f2aa.pack(side=LEFT) 

f2ab = Frame(f2a, width=450, height=330, bd=14, relief="raise") 
f2ab.pack(side=RIGHT) 
Tops.configure(background='black') 
f1.configure(background='black') 
f2.configure(background='black')

Answer 1

私はいくつかの書式設定の問題に気付きました。しかし、私はちょうどチェックボックスの問題に関する質問に答えるつもりです。

command = chkbutton_valueを含むように各チェックボックスの作成を変更する必要があります。

あなたのLattaチェックボタンをどのように作成するかを見てみましょう。

Latta = Checkbutton(f1ab, text="Latte \t", onvalue = 1, offvalue = 0, 
       font=('arial',18,'bold'), variable = var1, command = chkbutton_value) 

注：あなたは、あなたがそれ以外の場合はエラーになりますので、機能chkbutton_value():があなたのチェックボタンの作成前にあることを確認する必要があります。 NameError: name 'chkbutton_value' is not defined
