[python] How to set a tkinter window to a constant size

I'm programming a little game with tkinter and briefly, I'm stuck.

I have a kind od starting menu, in which are two buttons and one label.

If I just create the frame everything is fine, it has the size 500x500 pixels

I want the background not to change when I create the buttons and the labe, but it adapts the size whatever I do. Here is my code:

import tkinter as tk

def startgame():
    pass

mw = tk.Tk()              #Here I tried (1)
mw.title('The game')

back = tk.Frame(master=mw, width=500, height=500, bg='black')
back.pack()

go = tk.Button(master=back, text='Start Game', bg='black', fg='red',
                     command=lambda:startgame()).pack()
close = tk.Button(master=back, text='Quit', bg='black', fg='red',
                     command=lambda:quit()).pack()
info = tk.Label(master=back, text='Made by me!', bg='red',
                         fg='black').pack()

mw.mainloop()

I've searched around on stackoverflow and didn't get anything useful! I've found just one question a bit similar to mine but the answer didn't work. I tried this:

(1) mw.resizable(width=False, height=False)

I can't imagine what is the problem, I'm really desperate.

There are 2 solutions for your problem:

1. Either you set a fixed size of the Tkinter window; mw.geometry('500x500')

OR

2. Make the Frame adjust to the size of the window automatically;back.place(x = 0, y = 0, relwidth = 1, relheight = 1)

*The second option should be used in place of back.pack()

Here is the most simple way.

import tkinter as tk

root = tk.Tk()

root.geometry('200x200')
root.resizable(width=0, height=0)

root.mainloop()

I don't think there is anything to specify. It's pretty straight forward.

If you want a window as a whole to have a specific size, you can just give it the size you want with the geometry command. That's really all you need to do.

For example:

mw.geometry("500x500")

Though, you'll also want to make sure that the widgets inside the window resize properly, so change how you add the frame to this:

back.pack(fill="both", expand=True)

Try parent_window.maxsize(x,x); to set the maximum size. It shouldn't get larger even if you set the background, etc.

Edit: use parent_window.minsize(x,x) also to set it to a constant size!
