Mixing
“Stop” Button in Tkinter
-2
I'm trying to have a turtle animation start with a button and stop with a button. It's very easy to start with a button but I can't seem to be able to figure out a stop button? Here's my code so far:
import turtle
import tkinter as tk
def start():
t.forward(100)
t.right(90)
t.forward(100)
t.left(90)
t.forward(100)
t.right(90)
t.forward(100)
t.right(90)
t.forward(100)
def stop():
t.stop
def clear():
canvas.delete("all")
root = tk.Tk()
canvas = tk.Canvas(width = 500, height = 500)
canvas.pack()
t = turtle.RawTurtle(canvas)
tk.Button(text = "Start", command = start).pack(side = tk.LEFT)
tk.Button(text = "Stop", command = stop).pack(side = tk.LEFT)
tk.Button(text = "Clear", command = clear).pack(side = tk.LEFT)
root.mainloop()
Also the clear button works but afterwards the start button doesn't work anymore. If someone can help me with that as well.
Thank you to @Mike - SMT for helping me with this code. Here's the edited and fully functioning code:
import turtle
import tkinter as tk
def start(turtle_object, draw_path):
global tracker, start_ndex, end_ndex, started
tracker = False
if started == False:
started = True
for i in range(start_ndex, end_ndex):

They are the same question. You are not able to stop in between drawing because any even you would use to stop cant run until the function has ended. You will need to break up the drawing into sections and check a tracking variable.

You cannot stop each draw statement unless you provide a checker in between each line drawn.
The below code is just a rough mock up of how you could make something to check for a tracking variable used to tell it to no longer draw new lines.
The closest thing you can do to being able to stop drawing is something like this:
import turtle
import tkinter as tk
def start():
global tracker
tracker = False
if tracker == False:
t.forward(100)
if tracker == False:
t.right(90)
if tracker == False:
t.forward(100)
if tracker == False:
t.left(90)
if tracker == False:
t.forward(100)
if tracker == False:
t.right(90)
if tracker == False:
t.forward(100)
if tracker == False:
t.right(90)
if tracker == False:
t.forward(100)
def stop():
global tracker
tracker = True
def clear():
canvas.delete("all")
root = tk.Tk()
tracker = False
canvas = tk.Canvas(width = 500, height = 500)
canvas.pack()
t = turtle.RawTurtle(canvas)
tk.Button(text = "Start", command = start).pack(side = tk.LEFT)
tk.Button(text = "Stop", command = stop).pack(side = tk.LEFT)
tk.Button(text = "Clear", command = clear).pack(side = tk.LEFT)
root.mainloop()
This will at least stop drawing after each line but you cannot stop mid line draw.
Just for the fun of it if we add some tracking variables and use some cleaner logic we can start, stop and start again.
Update: From @cdlane's comment below I have added addition tracking and updated the clear function. This should allow for start stop start without issues and also be able to clear the field.
import turtle
import tkinter as tk
def start(turtle_object, draw_path):
global tracker, start_ndex, end_ndex, started
tracker = False
if started == False:
started = True
for i in range(start_ndex, end_ndex):
if tracker == False and i <= end_ndex:
pth = draw_path[i]
if pth[0] == "f":
turtle_object.forward(pth[1])
elif pth[0] == "r":
turtle_object.right(pth[1])
elif pth[0] == "l":
turtle_object.left(pth[1])
start_ndex += 1
def stop():
global tracker, started
tracker = True
started = False
def clear():
global t, tracker, started, start_ndex
canvas.delete("all")
tracker = False
start_ndex = 0
started = False
t = turtle.RawTurtle(canvas)
root = tk.Tk()
tracker = False
start_ndex = 0
started = False # added this tracking variable to prevent issues with spamming the start button.
draw_path = [["f", 100], ["r", 90], ["f", 100], ["l", 90], ["f", 100], ["r", 90], ["f", 100], ["r", 90], ["f", 100]]
end_ndex = len(draw_path)
canvas = tk.Canvas(width = 500, height = 500)
canvas.pack()
t = turtle.RawTurtle(canvas)
tk.Button(text = "Start", command = lambda: start(t, draw_path)).pack(side = tk.LEFT)
tk.Button(text = "Stop", command = stop).pack(side = tk.LEFT)
tk.Button(text = "Clear", command = clear).pack(side = tk.LEFT)

In your restartable solution, there are a couple of issues. First, it shares the "can't recover from 'clear'" issue of the OP's original. Second, if you're fast enough to click 'Start' multiple times during the run, the turtle goes astray. Not nit-picking, just interested to see how you'd handle problems I ran into in my own solution.

Nov 16 '18 at 18:09
@cdlane I agree there are limitations to my solutions. I will see if I can come up with a better solutions to contend with the other issues.
– Mike - SMT
Nov 16 '18 at 19:54
@cdlane I have updated my 2nd solution to contend with the issues you mentioned. I imaging I could probably build something cleaner but sometimes quick and dirty does the trick :D
– Mike - SMT
Nov 16 '18 at 20:16
Nice -- it runs solidly now! The turtle library keeps an internal list of turtles that it has created, so they are effectively never garbage collected. Better to reuse turtles, if you can, than allocate new ones. This is with respect to yourclear()method.
– cdlane
Nov 16 '18 at 23:37
@cdlane Hum. I never used turtle before and was not aware of how it remembers each turtle. What would you do in this case?

I agree with the ideas in @Mike-SMT's answer but I'd go about it a different way. The turtle and its controls seem very much like a Python generator to me so I've recast it as such. The turtle moves along a path, one pixel at a time, yielding control which may, or may not return. Or it may exhaust its path and stop the iteration:
import tkinter as tk
from turtle import RawTurtle
PATH = [(100.00, 0.00), (100.00, -100.00), (200.00, -100.00), (200.00, -200.00), (100.00, -200.00)]
def run():
for position in PATH:
turtle.setheading(turtle.towards(position))
while turtle.distance(position) > 1:
turtle.forward(1)
yield
def start():
global generator, running
running = True
while running:
try:
next(generator)
except ValueError: # user clicked start but already running
return
except TypeError: # new run
turtle.reset()
generator = run()
except StopIteration: # end of complete run
generator = None
running = False
break
def stop():
global running
running = False
def clear():
global generator
turtle.reset()
generator = None
root = tk.Tk()
canvas = tk.Canvas(width=500, height=500)
canvas.pack()
turtle = RawTurtle(canvas, "turtle")
running = True
generator = None
tk.Button(text="Start", command=start).pack(side=tk.LEFT, expand=tk.TRUE)
tk.Button(text="Stop", command=stop).pack(side=tk.LEFT, expand=tk.TRUE)
tk.Button(text="Clear", command=clear).pack(side=tk.LEFT, expand=tk.TRUE)
root.mainloop()
Also the clear button works but afterwards the start button doesn't
work anymore. If someone can help me with that as well.
You can replace your current clear() function with:
def clear():
t.clear()
if you just want to erase the path that's been drawn but leave the turtle where it ended up. If you want to erase the path and reset the turtle back to the starting point, instead do:
def clear():
t.reset()

I tried this command but there were some problems with indents (the 'return') which I tried fixing by replacing return with turtle.reset() but then there were problems with 'generator' not being defined in the line Next(generator) .
– Pokyzard
Nov 19 '18 at 18:32
@Pokyzard, an indentation oddity did creep in so I fixed and reloaded the example code. I did a copy of it from this web page and paste into a file without using an editor in between and it runs fine. Give it another try. (I assume you're using Python 3 based on your import of tkinter with a lower 't'.)

This will at least stop drawing after each line but you cannot stop mid line draw.
Just for the fun of it if we add some tracking variables and use some cleaner logic we can start, stop and start again.
Update: From @cdlane's comment below I have added addition tracking and updated the clear function. This should allow for start stop start without issues and also be able to clear the field.

In your restartable solution, there are a couple of issues. First, it shares the "can't recover from 'clear'" issue of the OP's original. Second, if you're fast enough to click 'Start' multiple times during the run, the turtle goes astray. Not nit-picking, just interested to see how you'd handle problems I ran into in my own solution.

Nice -- it runs solidly now! The turtle library keeps an internal list of turtles that it has created, so they are effectively never garbage collected. Better to reuse turtles, if you can, than allocate new ones. This is with respect to yourclear()method.

You cannot stop each draw statement unless you provide a checker in between each line drawn.
The below code is just a rough mock up of how you could make something to check for a tracking variable used to tell it to no longer draw new lines.
The closest thing you can do to being able to stop drawing is something like this:
import turtle
import tkinter as tk
def start():
global tracker
tracker = False
if tracker == False:
t.forward(100)
if tracker == False:
t.right(90)
if tracker == False:

t.right(90)
if tracker == False:
t.forward(100)
if tracker == False:
t.right(90)
if tracker == False:
t.forward(100)
def stop():

def clear():

I agree with the ideas in @Mike-SMT's answer but I'd go about it a different way. The turtle and its controls seem very much like a Python generator to me so I've recast it as such. The turtle moves along a path, one pixel at a time, yielding control which may, or may not return. Or it may exhaust its path and stop the iteration:
import tkinter as tk
from turtle import RawTurtle
PATH = [(100.00, 0.00), (100.00, -100.00), (200.00, -100.00), (200.00, -200.00), (100.00, -200.00)]
def run():
for position in PATH:
turtle.setheading(turtle.towards(position))
while turtle.distance(position) > 1:
turtle.forward(1)
yield
def start():
global generator, running
running = True
while running:
try:
next(generator)
except ValueError: # user clicked start but already running
return
except TypeError: # new run
turtle.reset()
generator = run()
except StopIteration: # end of complete run
generator = None
running = False
break
def stop():
global running
running = False
def clear():
global generator
turtle.reset()
generator = None
root = tk.Tk()
canvas = tk.Canvas(width=500, height=500)
canvas.pack()
turtle = RawTurtle(canvas, "turtle")
running = True
generator = None
tk.Button(text="Start", command=start).pack(side=tk.LEFT, expand=tk.TRUE)
tk.Button(text="Stop", command=stop).pack(side=tk.LEFT, expand=tk.TRUE)
tk.Button(text="Clear", command=clear).pack(side=tk.LEFT, expand=tk.TRUE)
root.mainloop()
Also the clear button works but afterwards the start button doesn't
work anymore. If someone can help me with that as well.
You can replace your current clear() function with:
def clear():
t.clear()
if you just want to erase the path that's been drawn but leave the turtle where it ended up. If you want to erase the path and reset the turtle back to the starting point, instead do:
def clear():
t.reset()

I tried this command but there were some problems with indents (the 'return') which I tried fixing by replacing return with turtle.reset() but then there were problems with 'generator' not being defined in the line Next(generator) .

@Pokyzard, an indentation oddity did creep in so I fixed and reloaded the example code. I did a copy of it from this web page and paste into a file without using an editor in between and it runs fine. Give it another try. (I assume you're using Python 3 based on your import of tkinter with a lower 't'.)

turtle = RawTurtle(canvas, "turtle")
running = True
generator = None
tk.Button(text="Start", command=start).pack(side=tk.LEFT, expand=tk.TRUE)
tk.Button(text="Stop", command=stop).pack(side=tk.LEFT, expand=tk.TRUE)
tk.Button(text="Clear", command=clear).pack(side=tk.LEFT, expand=tk.TRUE)
root.mainloop()
Also the clear button works but afterwards the start button doesn't
work anymore. If someone can help me with that as well.
You can replace your current clear() function with:
def clear():
t.clear()
if you just want to erase the path that's been drawn but leave the turtle where it ended up. If you want to erase the path and reset the turtle back to the starting point, instead do:
def clear():
t.reset()

I agree with the ideas in @Mike-SMT's answer but I'd go about it a different way. The turtle and its controls seem very much like a Python generator to me so I've recast it as such. The turtle moves along a path, one pixel at a time, yielding control which may, or may not return. Or it may exhaust its path and stop the iteration:
import tkinter as tk
from turtle import RawTurtle
PATH = [(100.00, 0.00), (100.00, -100.00), (200.00, -100.00), (200.00, -200.00), (100.00, -200.00)]
def run():
for position in PATH:
turtle.setheading(turtle.towards(position))
while turtle.distance(position) > 1:
turtle.forward(1)
yield
def start():
global generator, running
running = True
while running:
try:
next(generator)
except ValueError: # user clicked start but already running
return
except TypeError: # new run
turtle.reset()
generator = run()
except StopIteration: # end of complete run
generator = None
running = False
break
def stop():
global running
running = False
def clear():
global generator
turtle.reset()
generator = None
root = tk.Tk()
canvas = tk.Canvas(width=500, height=500)
canvas.pack()
turtle = RawTurtle(canvas, "turtle")
running = True
generator = None
tk.Button(text="Start", command=start).pack(side=tk.LEFT, expand=tk.TRUE)
tk.Button(text="Stop", command=stop).pack(side=tk.LEFT, expand=tk.TRUE)
tk.Button(text="Clear", command=clear).pack(side=tk.LEFT, expand=tk.TRUE)
root.mainloop()

I tried this command but there were some problems with indents (the 'return') which I tried fixing by replacing return with turtle.reset() but then there were problems with 'generator' not being defined in the line Next(generator) .

@Pokyzard, an indentation oddity did creep in so I fixed and reloaded the example code. I did a copy of it from this web page and paste into a file without using an editor in between and it runs fine. Give it another try. (I assume you're using Python 3 based on your import of tkinter with a lower 't'.)

There are a few post on how to stop the turtle. These post: How to stop the python turtle from drawing, Start and stop Python turtle with space bar, How Do You Make Python Turtle Stop Moving?.

None of those resolve my problem.

They are the same question. You are not able to stop in between drawing because any even you would use to stop cant run until the function has ended. You will need to break up the drawing into sections and check a tracking variable.
