【中文标题】边框和背景颜色未在 mac [python -Tkinter] 中显示

【英文标题】：Border and Background color not showing in mac [python -Tkinter]

【问题描述】：

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 bg 和 bd 不起作用。

from tkinter import *

root = Tk()
root.title('Calculator')
#-------------------------------Screen-------------------------------

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

#--------------------------------Row1--------------------------------

btn7 = Button(root,padx=30,pady=15,bd=5,fg='black',font=. 
('arial',30,'bold'),text='7').grid(row=1,column=0)
btn8 = Button(root,padx=30,pady=15,bd=5,fg='black',font=. 
('arial',30,'bold'),text='8').grid(row=1,column=1)
btn9 = Button(root,padx=30,pady=15,bd=5,fg='black',font= 
('arial',30,'bold'),text='9').grid(row=1,column=2)
btnc = Button(root,padx=28,pady=15,bd=5,fg='black',font=. 
('arial',30,'bold'),text='C',bg='green').grid(row=1,column=3)

#--------------------------------Row2--------------------------------

btn4 = Button(root,padx=30,pady=15,bd=5,fg='black',font=. 
('arial',30,'bold'),text='4').grid(row=2,column=0)
btn5 = Button(root,padx=30,pady=15,bd=5,fg='black',font=. 
('arial',30,'bold'),text='5').grid(row=2,column=1)
btn6 = Button(root,padx=30,pady=15,bd=5,fg='black',font=. 
('arial',30,'bold'),text='6').grid(row=2,column=2)
btnplus = Button(root,padx=30,pady=15,bd=5,fg='black',font=. 
('arial',30,'bold'),text='+',bg='orange').grid(row=2,column=3)

#--------------------------------Row3--------------------------------

btn1 = Button(root,padx=30,pady=15,bd=5,fg='black',font=. 
('arial',30,'bold'),text='1').grid(row=3,column=0)
btn2 = Button(root,padx=30,pady=15,bd=5,fg='black',font=. 
('arial',30,'bold'),text='2').grid(row=3,column=1)
btn3 = Button(root,padx=30,pady=15,bd=5,fg='black',font= 
('arial',30,'bold'),text='3').grid(row=3,column=2)
btnminus = Button(root,padx=34,pady=15,bd=5,fg='black',font=('arial',30,'bold'),text='- 
',bg='orange').grid(row=3,column=3)

#--------------------------------Row4--------------------------------

btn0 = Button(root,padx=30,pady=15,bd=5,fg='black',font=. 
('arial',30,'bold'),text='0').grid(row=4,column=0)
btndot = Button(root,padx=34,pady=15,bd=5,fg='black',font=. 
('arial',30,'bold'),text='.',bg='orange').grid(row=4,column=1)
btndivision = Button(root,padx=34,pady=15,bd=5,fg='black',font=. 
('arial',30,'bold'),text='/',bg='orange').grid(row=4,column=2)
btnmultiply = Button(root,padx=33,pady=15,bd=5,fg='black',font=. 
('arial',30,'bold'),text='*',bg='orange').grid(row=4,column=3)

#--------------------------------Row5--------------------------------

btnequals = Button(root,padx=74,pady=15,bd=5,fg='black',font=. 
('arial',30,'bold'),text='=',bg='green').grid(row=5,column=0,columnspan=2)
btnopenbrackets = Button(root,padx=34,pady=15,bd=5,fg='black',font=. 
('arial',30,'bold'),text='(',bg='orange').grid(row=5,column=2)
btnclosebrackets = Button(root,padx=33,pady=15,bd=5,fg='black',font=. 
('arial',30,'bold'),text=')',bg='orange').grid(row=5,column=3)

root.mainloop()

【问题讨论】：

由于平台限制，您无法更改 OSX 上按钮的背景或边框。

【参考方案1】：

试试这个：

from tkinter import *

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

#--------------------------------Row1--------------------------------

btn7 = Button(root,padx=30,pady=15,bd=5,fg='black',font=('arial',30,'bold'),text='7').grid(row=1,column=0)
btn8 = Button(root,padx=30,pady=15,bd=5,fg='black',font=('arial',30,'bold'),text='8').grid(row=1,column=1)
btn9 = Button(root,padx=30,pady=15,bd=5,fg='black',font= 
('arial',30,'bold'),text='9').grid(row=1,column=2)
btnc = Button(root,padx=28,pady=15,bd=5,fg='black',font=
('arial',30,'bold'),text='C',bg='green').grid(row=1,column=3)

#--------------------------------Row2--------------------------------

btn4 = Button(root,padx=30,pady=15,bd=5,fg='black',font=
('arial',30,'bold'),text='4').grid(row=2,column=0)
btn5 = Button(root,padx=30,pady=15,bd=5,fg='black',font=
('arial',30,'bold'),text='5').grid(row=2,column=1)
btn6 = Button(root,padx=30,pady=15,bd=5,fg='black',font=
('arial',30,'bold'),text='6').grid(row=2,column=2)
btnplus = Button(root,padx=30,pady=15,bd=5,fg='black',font=

#--------------------------------Row3--------------------------------

root.mainloop()

【讨论】：

请解释一下好吗？

Root["bg"] = "color" 将背景颜色更改为您设置的任何颜色

OSX 不允许您更改按钮的背景，这是 OP 所要求的。这个答案没有解决这个问题。
