Python 3.0 using turtle.onclick

Question

So here is my problem, I have to make a picture for my CS class and it is really frustrating estimating in turtle. I planed to use .onclick() to show me to position.

Answer 1

Awesome job figuring out a solution on your own.

Did you ever look through the docs for turtle?

http://docs.python.org/2/library/turtle.html

Looks like you can import screen as well as turtle from the module. screen has an onclick event of its own that does what you expect it to.

Note the following line on how to get access to the screen object:

The function Screen() returns a singleton object of a TurtleScreen subclass.
This function should be used when turtle is used as a standalone tool for
doing graphics. As a singleton object, inheriting from its class is not
possible.

Disclaimer: I've never used turtle before.

Answer 2

You have to get first the screen object the turtle is drawing on and then call onclick() of the screen object. Here is an example:

import turtle as t

def getPos(x,y):
    print("(", x, "," ,y,")")
    return

def main():
    s = t.getscreen()
    s.onclick(getPos)
    t.mainloop()

main()

Alright, I figured out a work around. Its not a perfect solution but it works pretty well. Because onclick will only respond if you click on the arrow head, I made the arrow head encompass the entire screen. Then I hid it. What you need to do is hover over the position you want to go to, press "a" and when it goes black click the screen. The shell will then display the coordinates you need. Make sure you always go back to (1000,0).

import turtle as t

def showTurtle():
    t.st()
    return

def getPos(x,y):
    print("(", x, "," ,y,")")
    return

def hideTurtle(x,y):
    t.ht()
    return

def main():
    t.speed(20)
    t.shapesize(1000,1000)
    t.up()
    t.goto(1000,0)
    t.ht()
    t.onkey(showTurtle,"a")
    t.listen()
    t.onclick(getPos)
    t.onrelease(hideTurtle)
    t.mainloop()
main()

Also, in case anyone from my class finds this, I am a CS student in binghamton and if you use this I recommend leaving no trace. The prof has seen this and will recognize it.

Answer 4

Python 3.7 version.

import turtle as t

def click(x,y):
  print('Clicked:', x, y)

def main():
  s = t.Screen()
  s.onclick(click)

  s.mainloop()

main()

Note that the printing takes place at the console, not on Turtle.

Answer 5

You need to use the Screen class. However, if you want to stay away from OOP, you can use the built-in method turtle.onscreenclick(func).

Replace

def main():
    t.onclick(getPos)
    t.mainloop()
main()

with

def main():
    t.onscreenclick(getPos)
    t.mainloop()
main()

Answer 6

I have a small child coder but I learn a lot.

I like to do coding only that for somebody say that you created good but I also love to share out what I learn.

You came here for codes onclick codes are here:

You need to do the following:

# import package 
import turtle 
   
# screen object 
wn = turtle.Screen() 
  
# method to perform action 
def fxn(x, y): 
  turtle.goto(x, y) 
  turtle.write(str(x)+","+str(y)) 
  
# onclick action  
wn.onclick(fxn) 
wn.mainloop()`

Now, just click on the screen and see the magic
