How to set border color of certain Tkinter widgets?
提问by Jeff
I'm trying to change the background color of my Tkinter app, but for certain widgets it leaves a white border around the edges.
我正在尝试更改 Tkinter 应用程序的背景颜色，但对于某些小部件，它的边缘会留下白色边框。
For example, this:
例如，这个：
from tkinter import *
COLOR = "black"
root = Tk()
root.config(bg=COLOR)
button = Button(text="button", bg=COLOR)
button.pack(padx=5, pady=5)
entry = Entry(bg=COLOR, fg='white')
entry.pack(padx=5, pady=5)
text = Text(bg=COLOR, fg='white')
text.pack(padx=5, pady=5)
root.mainloop()

Just use
只需使用
widget.config(highlightbackground=COLOR)
Furthermore, if you don't want that border at all, set the highlightthicknessattribute to 0 (zero).
此外，如果您根本不需要该边框，请将highlightthickness属性设置为 0（零）。

You have to set the two highlights (with and without focus) to have a continuous color.
您必须将两个高光（有焦点和无焦点）设置为连续颜色。
from tkinter import *
root = Tk()
e = Entry(highlightthickness=2)
e.config(highlightbackground = "red", highlightcolor= "red")
e.pack()
root.mainloop()
