I am trying to change the border color of a button in tkinter python

Question

I am trying to change to border color of a button in python tkinter, I've tried putting it in a frame but it does not work:

import tkinter
from tkinter import *
root = Tk()

l_f = Frame(root, bg="black")
l_f.pack()
l = Button(l_f, text="fdffdfd", bg="white", fg="white")
l.pack()

root.mainloop()

Answer 1

You packed a frame , but didn't set any option of that frame, to give a border effect.

Try: l_f = Frame(root, highlightbackground = "black", highlightthickness = 2, bd=0)

---

Also, you can use LabelFrame in place of frame, to add border to a button.

l_f = LabelFrame(root, bg = "black", bd=2)

Making a button relief have a different color to the button face and have it work like button is not trivial.

Here is a working example of a button with color that performs just like a standard button.

I've changed the way Button key press and release works, in order to match button behaviour.

import tkinter as tk

class color_button:

    def virtual(self, o, n, f, args):
        '''virtual(o, n, f, args)'''
        o.event_add(n, *args)
        b = o.bind(n, f)
        return b

    def flexx(self, o, r = 0, c = 0, rw = 1, cw = 1) ->'Set grid manager to grow':
        '''flexx(o(TkContainer), r=0, c=0, rw=1, cw=1)'''
        if r != None:
            o.rowconfigure(r, weight = rw)
        if c != None:
            o.columnconfigure(c, weight = cw)

    def closer(self, ev):
        self.master.destroy()

    def __init__(self, color = "red"):
        self.master = tk.Tk()
        self.flexx(self.master)

        self.frame = tk.LabelFrame(
            self.master, bg = color, bd = 2, relief = "raised")
        self.frame.grid row = 0, column = 0, sticky = "nsew")
        self.flexx(self.frame)
        self.button = tk.Button(
            self.frame, text = "button", relief = "flat",
            bd = 0, command = self.action)
        self.button.grid(row = 0, column = 0, sticky = "nsew")
        self.virtual(
            self.button, "<<PRESS>>",
            self.press, ( "<ButtonPress-1>", "<KeyPress-space>" ))
        self.virtual(
            self.button, "<<RELEASE>>",
            self.release, ( "<ButtonRelease-1>", "<KeyRelease-space>" ))
        self.master.bind("<Escape>", self.closer)

    def press(self, ev):
        self.frame["relief"] = "sunken"
        return "break"

    def release(self, ev):
        self.frame["relief"] = "raised"
        wd = ev.widget
        if ev.num != 1 or wd.winfo_containing( *wd.winfo_pointerxy( )) == wd:
            wd.invoke( )
        return "break"

    def action(self):
        print( "Done" )

if __name__ == "__main__":

    main = color_button( )
    main.master.mainloop()
