Change ttk Entry focus color - Python-CodePudding

I am trying to change the focus color of a ttk.Entry widget in python (blue border):

I know that we can change the focus color of the notebook tabs with style.configure('Tab', focuscolor='red'), so I wonder how to do it with an entry widget?

Here is my code:

import tkinter
from tkinter import ttk

root = tkinter.Tk()

style = ttk.Style()
style.theme_use('clam')
style.configure('TEntry', focuscolor='red') # don't work

ttk.Entry(root).grid(padx=10, pady=10)

root.mainloop()

CodePudding user response：

As suggested by @Thingamabobs and @acw1668 It's possible to change the focus color of a ttk.Entry by mapping the focus state in its style property. Here is the working code:

import tkinter
from tkinter import ttk

root = tkinter.Tk()

style = ttk.Style()
style.theme_use('clam')
style.map('TEntry', lightcolor=[('focus', 'white')])

ttk.Entry(root).grid(padx=10, pady=10)

root.mainloop()

My final goal was to hide the focus border so I changed its color to white (the background color), and now the result looks like this: (The black border is just the original border of the entry)
