推荐答案

您可以通过使用ttk样式将按钮释放方式设置为flat或将borderwidth设置为0来实现所需的功能.但是，某些ttk主题没有考虑这些样式设置，其中之一是Windows中的默认主题.将主题设置为蛤"或替代"应该可以解决您的问题.

What you want can be achieved by setting the button relief to flat or borderwidth to 0 using a ttk style. However, some ttk themes don't take into account these style settings, and one of them is the default theme in Windows. Setting the theme to 'clam' or 'alt' should solve your problem.

import tkinter as tk
from tkinter import ttk

root = tk.Tk()

b1 = tk.Button(root, text='tk.Button', borderwidth=0)
b1.pack()

s = ttk.Style(root)
s.theme_use('clam')
s.configure('flat.TButton', borderwidth=0)
# s.configure('flat.TButton', relief='flat') gives the same result

b2 = ttk.Button(root, style='flat.TButton', text='ttk.Button')
b2.pack()

root.mainloop()
