Finally found some code at http://www.python-forum.de/viewtopic.php?f=1&t=24823&start=0 which provides a scrolled canvas for the turtle:

import turtle
import Tkinter as tkinter

root = tkinter.Tk()
root.geometry('500x500-5+40') #added by me
cv = turtle.ScrolledCanvas(root, width=900, height=900)
cv.pack()

screen = turtle.TurtleScreen(cv)
screen.screensize(2000,1500) #added by me
t = turtle.RawTurtle(screen)
t.hideturtle()
t.circle(100)

root.mainloop()

Answer 2

You don't need to call Tkinter functions directly to get scrollbars in turtle. You just need to call turtle.screensize and set a screen size that's larger than the display window in at least one of its dimensions. I find it most convenient to open the display window at its default size and let the user resize it, if desired.

Here's a short demo:

import turtle

win_width, win_height, bg_color = 2000, 2000, 'black'

turtle.setup()
turtle.screensize(win_width, win_height, bg_color)

t = turtle.Turtle()
#t.hideturtle()
#t.speed(0)
t.color('white')

for _ in range(4):
    t.forward(500)
    t.right(90)

turtle.done()
