无法为 Tkinter 按钮的边框着色?
问题描述
它适用于其他一些小部件，但不适用于按钮.
It works with some other widgets, but not with Buttons.
from Tkinter import *
root = Tk()
root.geometry("600x300+400+50")
btn_up = Button(root, text='Go UP')
btn_up.config(highlightbackground="red", highlightcolor="red", highlightthickness=10, relief=SOLID)
btn_up.pack()
root.mainloop()

解决方案
我用的是linux，当我运行你的代码时，我得到一个带有粗红色边框的按钮，所以看起来默认的Windows主题不支持highlightthickness 而默认的 linux 主题会这样做.
I am using linux and when I run your code, I get a button with a thick red border, so it looks like that the default Windows theme does not support highlightthickness while the default linux theme does.
如果你想改变边框颜色，可以使用一些 ttk 主题，比如 'clam':
If you want to change the border color, it is possible with some ttk themes like 'clam':
from Tkinter import *
import ttk
root = Tk()
style = ttk.Style(root)
style.theme_use('clam')
style.configure('my.TButton', bordercolor="red")
ttk_button = ttk.Button(root, text='Go UP', style='my.TButton')
ttk_button.pack()
root.mainloop()
但是，使用 style.configure('my.TButton', borderwidth=10) 更改边框宽度不会按预期增加红色边框的宽度.
However, changing the borderwidth, with style.configure('my.TButton', borderwidth=10) does not increase the width of the red border as expected.
