无法在Tkinter中更改按钮的颜色

Question

I am not able to change the color of the button using fg and bg. I get this error: _tkinter.TclError: unknown option "-fg"

_scrape_btn = ttk.Button(_mainframe, text='Scrape!', command=save, fg='blue')
_scrape_btn.grid(row=2, column=0, sticky=(N,E), pady=2)

_compress_btn = ttk.Button(_mainframe, text='Compress!', command=compress)
_compress_btn.grid(row=2, column=1, sticky=W, pady=2)

Answer 1

The reason this is happening is because you are using ttk.Button instead of tk.Button . The options such as fg , bg are not supported by ttk . Instead you will have to use Style option and configure it as you require. Here is an example.

import tkinter as tk
import tkinter.ttk as ttk

root = tk.Tk()

style = ttk.Style()
style.configure("TButton", foreground="blue", background="orange")

myButton = ttk.Button(text="Scrape", style="TButton")
myButton.grid()

root.mainloop()
