Why isn't the tkinter button showing up on the screen?

Question

I am making a game and the first thing on the screen is a button that says play game. But the button isn't showing up on the screen for some reason? The function play_sound_game is basically the rest of my code.

I have already tried removing turtle.mainloop() but that doesn't work either.

    import turtle
    import tkinter as tk
    import time
    import pygame

    screen = turtle.Screen()

    turtle.ht()
    screen.bgcolor("blue")
    turtle.color('deep pink')
    style = ('Courier', 80, 'italic')
    turtle.pu()
    turtle.goto(-318,176)
    turtle.pu
    turtle.write('RHYMING WORDS', font=style)
    turtle.hideturtle()


    turtle.mainloop()


    #Button for play game
    button_playgame = tk.Button(canvas.master, text="Play Game", command=play_sound_game, font=('Arial', '65',"bold"), foreground = 'red')

    button_playgame.config(height = -1, width = 4)
    canvas.create_window(272, 88, window=button_playgame)

I didn't get any error messages.

You have not rendered the button ```(.pack, .grid, .place)```also...```height = -1```? — Joshua Nixon, Aug 04 '19 at 21:42
Can you please tell me what I have to replace in my code to make it work. That would really helpfull, and I know how Tkinter works — Python123, Aug 04 '19 at 21:44
If you knew how Tkinter works then you wouldn't have this issue lol. Like my first comment suggests, you have to place the widget...but since you know how tkinter works... — Joshua Nixon, Aug 04 '19 at 21:46
your problem is `mainloop` which create main window and runs all time till you close window. If you want to add something then you have to do it before `mainloop():` — furas, Aug 04 '19 at 21:48
and you don't have to use `(.pack, .grid, .place)` to add widget to `Canvas` — furas, Aug 04 '19 at 21:48
I didn't say to remove `mainloop()` because tkinter needs it - OP has to create button before `mainloop()`. — furas, Aug 04 '19 at 21:50
When I do that it gives me an error saying canvas is not defined — Python123, Aug 04 '19 at 21:54
@JoshuaNixon: they don't need to call pack, place, or grid. They are adding the window to the canvas with create_window. — Bryan Oakley, Aug 04 '19 at 21:54
you have error but it is different problem - I already has working code for you. I have to only describe it in aswer. — furas, Aug 04 '19 at 21:55

turtle uses widget Canvas from module tkinter. To add button you have to get access to this canvas

canvas = screen.getcanvas()

and then you can use it in

tk.Button(canvas.master, ...)

and

canvas.create_window(...)

Because turtle.mainloop() runs all time till you close window so you have to create button before mainloop()

Working example.

import turtle
import tkinter as tk

def play_sound_game():
    pass

screen = turtle.Screen()

turtle.ht()
screen.bgcolor("blue")
turtle.color('deep pink')
style = ('Courier', 80, 'italic')
turtle.pu()
turtle.goto(-318,176)
turtle.pu
turtle.write('RHYMING WORDS', font=style)
turtle.hideturtle()

canvas = screen.getcanvas()

button_playgame = tk.Button(canvas.master, text="Play Game", command=play_sound_game, font=('Arial', '65',"bold"), foreground='red')
#button_playgame.config(height=1, width=4)

canvas.create_window(272, 88, window=button_playgame)

turtle.mainloop()

Also one more question. Is it possible to change the background color of the button? – Python123 Aug 04 '19 at 22:05
yes, `background="blue"` or shorter `bg="blue"`. Using hex code (#RRGGBB) `bg="#FF00DD"`. Doc: [Button](http://effbot.org/tkinterbook/button.htm) – furas Aug 04 '19 at 22:19
The button color stays at white – Python123 Aug 04 '19 at 22:41
on Linux it changes color to blue. It is white only when mouse is over button (hover) - but button has other options to change it. If you use other system then Linux then maybe your system not let change it. – furas Aug 04 '19 at 23:00
Yeah I am using mac so probably – Python123 Aug 05 '19 at 23:14
