How do I change the foreground or background colour of a Tkinter button on Max OS X 10.6 with Python 2.6.1?

Question

I've been working through the Tkinter chapters in Programming Python and encountered a problem where the foreground and background colours of a button will not change. I am working on a Mac OS X 10.6 system with Python 2.6.1. The colours of a label will change, but not the colours of a button. For example:

from Tkinter import *

Label(None, text='label', fg='green', bg='black').pack()
Button(None, text='button', fg='green', bg='black').pack()

mainloop()

On my Mac system the colours of the label change, but the colours of the button do not. On a Windows system with Python 2.6.1 the colours of both the label and button change.

Anyone know what is going wrong?

EDIT:

I've checked Interface Builder and it appears that there is no option to change the foreground or background colour of a button in that tool. There is the ability to edit the foreground and background colours of a label.

The Mac OS X rendering system (Quartz?) may just not support (easily) changing the fg and bg of a button.

Answer 1

I think the answer is that the buttons on the mac simply don't support changing the background and foreground colors. As you've seen, this isn't unique to Tk.
