Changing Color Of Buttons In Tkinter Works On Windows But Not Mac Osx

Edit: I tried it on Windows and it works, I guess it is a OSX bug? The following code does not work for some reason and the button stays white z = Button(frame, text='Nothing Sched

Solution 1:

for python3, try

pip3 install tkmacosx

Then it should be work with this:

from tkmacosx import Button as button
B1 = button(frame, text = 'Hello!', bg = 'black', fg = 'white',command = testing)

Solution 2:

In this page of the tcl/tk wiki are listed some problems related to Mac and the color of labels and buttons's backgrounds. For example:

...

The Mac OS X background color should not be white, it should be #ececec. Since winfo rgb does not work properly on the mac colors, this makes it difficult to get the proper default color.

... etc.

Saludos!,

Solution 3:

I meet the same problem on osx 10.14.3, then I replace with the ttk button, and it works!

from tkinter importttkb1= ttk.Button(root, text="start", width=15, command=begin)

Solution 4:

Use tkmacosx Library it allows you to change the button color in MacOSX.

Install

pip install tkmacosx

Example

from tkinter import *
from tkmacosx import Button

root = Tk()
root.geometry("200x200")
B1 = Button(root, text='Button', bg='red')
B1.grid(row=0, column=1)

root.mainloop()
