python - How do I change the background of a Frame in Tkinter? -

i have been creating email program using tkinter, in python 3.3. on various sites have been seeing frame widget can different background using frame.config(background="color"). however, when use in frames gives following error:

_tkinter.tclerror: unknown option "-background" 

it not work when doing following:

frame = frame(root, background="white") 

or:

frame = frame(root) frame.config(bg="white") 

i can't figure out. post whole source code dont want exposed on internet, frame creation goes this:

mail1 = frame(self, relief=sunken) mail1.pack() mail1.place(height=70, width=400, x=803, y=109) mail1.config(background="white") 

i have tried multiple options trying modify background. frame wrap around email preview inbox.

in case it's needed, way importing modules:

import tkinter, time, base64, imaplib, smtplib imaplib import * tkinter import * tkinter.ttk import * 

the following full traceback:

gives following error code answer:

solved! thanks. inbox bar right, background needed white.

the root of problem unknowingly using frame class ttk package rather tkinter package. 1 ttk not support background option.

this main reason why shouldn't global imports -- can overwrite definition of classes , commands.

i recommend doing imports this:

import tkinter tk import ttk 

then prefix widgets either tk or ttk :

f1 = tk.frame(..., bg=..., fg=...) f2 = ttk.frame(..., style=...) 

it becomes instantly obvious widget using, @ expense of tiny bit more typing. if had done this, error in code never have happened.
