How to change the color of ttk button

问题

I am using Python 3.x on Windows.

My problem is I want to customize a button widget of ttk by completely changing its background and foreground color. But so far, I have been unsuccessful.

My desired button is:

I read the ttk.Style guide and used their code:

ttk.Style().configure("TButton", padding=6, relief="flat",
   background="#000")

btn = ttk.Button(text="Sample")
btn.pack()

But it's changing the border color instead of the whole button bakground. Here is the output:

Kindly help me achieve my desired button.

Unfortunately, there isn't an easy way to change the foreground of a button from the ttk library. It is always the standard Windows gray like in your picture.

But you can easily get what you want with a normal tkinter.Button if you set the right options. Below is an example script:

import tkinter as tk

root = tk.Tk()
btn = tk.Button(root, 
                bg='#000000',
                fg='#b7f731',
                relief='flat',
                text='hello button',
                width=20)
btn.pack()

root.mainloop()

And here is what it will look like:

Also, the shade of green I picked was just an example one that I thought was pretty close to what you wanted. But you can specify any hex color code you want. If you need to turn a RGB value into hex, a simple trick is to use str.format like so:

>>> rgb = (183, 247, 49)
>>> '#{:02x}{:02x}{:02x}'.format(*rgb)
'#b7f731'
>>>

import ttk

root.style = ttk.Style()
#root.style.theme_use("clam")
style.configure('TButton', background='black')
style.configure('TButton', foreground='green')
button= ttk.Button(self, text="My background is black and my foreground is green.")

works for me if you want to change all your buttons to the one you "desire", with Python 2.7 and Tkinter 8.6
