Hello, I'm having trouble with this small example program:
http://en.literateprograms.org/Bresenham%27s_line_algorithm_%28Python%29 When I run it, I only get a blank grey window. I'm running Python 2.6 under Windows XP. If there's a problem with the code, I can't see it... it seems like it should work. Can anyone else try this and see if it works for them? If I stick this line in before the loop, it does draw a red line, so I know my copy of Python/Tkinter is working: canvas.create_line(10, 100, 5, 50 , fill='red')
