[Tkinter] Button States

[deanhystad]

What do you think my_btn is after this code executes? If you don't know you should find out.

my_btn = Button(root, text = "CLICK ME", command = my_fun).pack()

Classes are a good idea for GUI applications because they combine functions with a private namespace that holds all the related variables. It makes for a very clean solution. But classes are not required. Below is an example that passes the required information as an argument to the callback.

import random
from tkinter import *

colors = ['red', 'green', 'blue', 'orange', 'yellow']

def my_fun(button):
  button['fg'] = random.choice(colors)
 
root = Tk()
b1 = Button(root, text = "CLICK ME")
b1.configure(command = lambda : my_fun(b1))
b1.pack()

b2 = Button(root, text = "ME TOO")
b2.configure(command = lambda : my_fun(b2))
b2.pack()
