Background color for Tk in Python

问题

I'm writing a slideshow program with Tkinter, but I don't know how to change the background color to black instead of the standard light gray. How can this be done?

import os, sys
import Tkinter
import Image, ImageTk
import time

root = Tkinter.Tk()
w, h = root.winfo_screenwidth(), root.winfo_screenheight()
root.overrideredirect(1)
root.geometry("%dx%d+0+0" % (w, h))
root.focus_set()
root.bind("<Escape>", lambda e: e.widget.quit())
image = Image.open(image_path+f)
tkpi = ImageTk.PhotoImage(image)        
label_image = Tkinter.Label(root, image=tkpi)
label_image.place(x=0,y=0,width=w,height=h)
root.mainloop(0)

回答1:

root.configure(background='black')

or more generally

<widget>.configure(background='black')

回答2:

I know this is kinda an old question but:

root["bg"] = "black"

will also do what you want and it involves less typing.

回答3:

Its been updated so

root.configure(background="red")

is now:

root.configure(bg="red")

回答4:

widget['bg'] = '#000000'

or

widget['background'] = '#000000'

would also work as hex-valued colors are also accepted.

回答5:

config is another option:

widget1.config(bg='black')
widget2.config(bg='#000000')

or:

widget1.config(background='black')
widget2.config(background='#000000')
