Question

So for one of my classes I am updating the game Minesweeper. So for the game I was wanting to change the size of the grid based on user preference. I am new to working with tkMesseageBoxs. I am trying to update the variable SIZE_X and SIZE_Y with the tkMeassage box. Size_x and Size_y control the size of the grid. For the first one I tried assigning it to the variable a and b. For the other variables I was having trouble returning them. When I run the minesweeper game it only shows a blank screen. I am having trouble returning the variables back into the game. If you can help, it would be greatly appreciated.

ak: bool = tkMessageBox.askyesno("Difficulty", "Would you like to play the easy version?")

if ak:

a = 10

b = 10

else:

ka = tkMessageBox.askyesno("Difficulty", "Would you like to play a harder version?")

if ka:

SIZE_X = 20

SIZE_Y = 20

else:

akk = tkMessageBox.showinfo("Difficulty", "Looks like you will play the harder version after all.")

SIZE_X = 35

SIZE_Y = 35

SIZE_X = a

SIZE_Y = b

STATE_DEFAULT = 0

STATE_CLICKED = 1

STATE_FLAGGED = 2

WINS = 0

the programming language is python.

Answer 1

I am assuming that you are using python 3. This is allbecause there are changes in the python 3.

Here is my code that will allow you to decide window size as par your requirement. also maintain those indentation :

from tkinter import *
import tkinter.messagebox

gui = Tk(className='Python Examples - Window Size')
# set window size
#gui.geometry("300x300")



ak: bool = tkinter.messagebox.askyesno("Difficulty", "Would you like to play the easy version?")
if ak:
    a = 200
    b = 200
    gui.geometry('%dx%d' % (a, b))
else:
    ka = tkinter.messagebox.askyesno("Difficulty", "Would you like to play a harder version?")
    
    if ka:
        a = 400
        b = 400
        gui.geometry('%dx%d' % (a, b))
    else:
        akk = tkinter.messagebox.showinfo("Difficulty", "Looks like you will play the harder version after all.")
        a = 600
        b = 600
        gui.geometry('%dx%d' % (a, b))


gui.mainloop() 

Another way, where the window will close and open the game window as you want:

import tkinter as tk

def easy():
    mw.destroy()
    gui = tk.Tk(className='Python Examples - Window Size')
    a = 200
    b = 200
    gui.geometry('%dx%d' % (a, b))
    gui.mainloop()
    
def harder():
    mw.destroy()
    gui = tk.Tk(className='Python Examples - Window Size')
    a = 400
    b = 400
    gui.geometry('%dx%d' % (a, b))
    gui.mainloop()
    
 
def tough():
    mw.destroy()
    gui = tk.Tk(className='Python Examples - Window Size')
    a = 600
    b = 600
    gui.geometry('%dx%d' % (a, b))
    gui.mainloop()

mw = tk.Tk()

#If you have a large number of widgets, like it looks like you will for your
#game you can specify the attributes for all widgets simply like this.
mw.option_add("*Button.Background", "white")
mw.option_add("*Button.Foreground", "black")

mw.title('The game')
#You can set the geometry attribute to change the root windows size
mw.geometry("200x200") #You want the size of the app to be 500x500
mw.resizable(0, 0) #Don't allow resizing in the x or y direction

back = tk.Frame(master=mw,bg='white')
back.pack_propagate(0) #Don't allow the widgets inside to determine the frame's width / height
back.pack(fill=tk.BOTH, expand=1) #Expand the frame to fill the root window

#Changed variables so you don't have these set to None from .pack()
go1 = tk.Button(master=back, text='Easy', command=easy)
go1.pack(side=tk.LEFT)
go2 = tk.Button(master=back, text='Harder', command=harder)
go2.pack(side=tk.LEFT)
go3 = tk.Button(master=back, text='Tough', command=tough)
go3.pack(side=tk.LEFT)
close = tk.Button(master=back, text='Quit', command=mw.destroy)
close.pack(side=tk.LEFT)


mw.mainloop()
