Is there a way to change tkcalendar's color?

问题

I'm trying to make tkcalendar blend in with my window.

import tkinter
from tkcalendar import Calendar



window = tkinter.Tk()
window.configure(background = "black")



cal = Calendar(window, background = "black" , disabledbackground = "black" , borderbackground = "black" , headersbackground = "black" , normalbackground = "black" )
cal.config(background = "black")
cal.pack()


window.mainloop()

I've read through the tkcalendar documentation and tried changing all the style elements by calling the configure method of widget class :

cal.configure(background = "black")

; however, my calendar still remains gray instead of blending into the black window background. Is it possible to change the actual background color of the calendar?

回答1:

You are doing it the right way, except that OSX default theme does not support changing background colors (it is based on pictures I think so you can only change the text color). The solution is to use a different ttk theme (e.g. clam or alt):

import tkinter
from tkinter import ttk
from tkcalendar import Calendar

window = tkinter.Tk()
window.configure(background = "black")

style = ttk.Style(window)
style.theme_use('clam')   # change theme, you can use style.theme_names() to list themes

cal = Calendar(window, background="black", disabledbackground="black", bordercolor="black", 
               headersbackground="black", normalbackground="black", foreground='white', 
               normalforeground='white', headersforeground='white')
cal.config(background = "black")
cal.pack()

By the way, the option 'borderbackground' does not exists, the correct name is 'bordercolor'.

回答2:

The Calendar class in tkcalendar module is a subclass of ttk.Frame.

class Calendar(ttk.Frame):

You must use the styling specific to ttk that uses themes to alter its attributes.
