如何使用 TTK 更改按钮的字体和背景？

Question

事实上，我想用TTK为我的图形项目制作一个按钮；但遗憾的是我没能做到这一点。经过大量尝试和错误后，我意识到问题出在字体和背景上。

我尝试通过从按钮中删除字体和背景来解决问题，但它们对于它来说是绝对必要的。我期望它能工作，但结果是一个错误！（我不得不说我的项目尚未完成，我将向其中添加许多其他选项卡和商品；但我想在继续之前解决这个问题。） 这是我的代码：

import tkinter as tk 
from tkinter import ttk
window = tk.Tk()
window.geometry('800x600')
window.title('store calculations')
window.configure(background='gray')

tab_control = ttk.Notebook(window)

tab_1 = ttk.Frame(tab_control)
tab_2 = ttk.Frame(tab_control)

tab_control.add(tab_1,text='Installment purchase')
tab_control.add(tab_2,text='Delmonti')
tab_control.pack(expand=1,fill='both')

def run ():
    amount = int(txt_amount.get())
    prepayment = int(txt_prepayment.get())
    installments = int(txt_installments.get())
    money_left = amount - prepayment
    each_month = money_left / installments + money_left * 3 / 100
    if each_month == int(each_month):
        each_month = int(each_month)
    else:
        each_month = round(each_month,2)
    txt_each_month.insert(0,str(each_month))

def clear():
    txt_amount.delete(first=0,last='end')
    txt_prepayment.delete(first=0,last='end')
    txt_installments.delete(first=0,last='end')
    txt_each_month.delete(first=0,last='end')

def one_third():
    amount = int(txt_amount.get())
    one_third_of_the_amount = amount * 1 / 3
    if one_third_of_the_amount == int(one_third_of_the_amount):
        one_third_of_the_amount = int(one_third_of_the_amount)
    else:
        one_third_of_the_amount = round(one_third_of_the_amount,2)
    txt_prepayment.insert(0,str(one_third_of_the_amount))

lbl_amount = tk.Label(tab_1,text='Amount',font=('Tahoma',18))

window.mainloop()

只要您的按钮不显示颜色和正确的字体，简单的解决方法是您需要将按钮从

... = ttk.Button(tab_1,...)

到

... = tk.Button(tab_1,...)

这应该可以修复按钮的样式
