我在 windows 中尝试过相同的代码，它工作正常，但在 mac GUI 按钮中不显示边框和背景颜色的效果。 例如。 btnc = Button(root,padx=28,pady=15,bd=5,fg='black',font=. ('arial',30,'bold'),text='C',bg='green').grid(row=1,column=3) 在上面的代码行中 bg 和 bd 不起作用。
from tkinter import *

答案 0 :(得分：-1)
试试这个：

root = Tk()
root.title('Calculator')

root["bg"] = "blue"
Display = Entry(root,font=('arial',30,'bold'),fg='white',bg='green',justify='right',bd=10)
Display.grid(columnspan=4)
