Yes the link didn't have the simple examples I hoped for. How's this:
-----------------------------
import pygame
import time
pygame.init()
screen = pygame.display.set_mode((1024, 768) )
red = (255,0,0)
green = (0,255,0)
screen.fill( (255,255,255) )
pygame.draw.lines(screen, red, False, ((0,0),(100,100)))
pygame.draw.lines(screen, green, False, ((0,100),(100,0)))
pygame.display.update()
time.sleep(5)
pygame.quit()
------------------------------
This looks very reasonable. If one wants buttons, however, I still
recommend to use Tkinter. The same program looks not much more complex:
----------------------------------
import tkinter as Tk
from tkinter import ttk
# Boilerplate: set up a resizeable canvas in a window
root = Tk.Tk()
canvas = Tk.Canvas(root)
canvas.pack(expand=True, fill='both')
canvas.create_line(0, 0, 100, 100, fill='red')
canvas.create_line(0, 100, 100, 0, fill='green')
# add a button to close the program
button = ttk.Button(root, text='Leave', command=exit)
button.pack()
# run the program
Tk.mainloop()
-----------------------------------
The boilerplate looks a bit less intuitive - instead of pygame.init()
you have to set up a canvas in a window - but the actual drawing code
looks quite similar. And it is trivial to add a button or other widgets,
as shown above.
