The turtle module provides turtle graphics primitives, in both object-oriented and procedure-oriented ways. Because it uses Tkinter for the underlying graphics, it needs a version of Python installed with Tk support.
turtle.onclick()
This function is used to bind fun to a mouse-click event on this turtle or on canvas.
Syntax :
turtle.onclick(fun, btn=1, add=None)
Parameters:
| Arguments | Description |
| fun | a function with two arguments, to which will be assigned the coordinates of the clicked point on the canvas |
| btn | number of the mouse-button defaults to 1 (left mouse button) |
| add | True or False. If True, the new binding will be added, otherwise, it will replace a former binding |
Below is the implementation of the above method with some examples :
Example 1 :
# import package
import turtle
# method to action
def fxn(x,y):
# some motion
turtle.right(90)
turtle.forward(100)
# turtle speed to slowest
turtle.speed(1)
# motion
turtle.fd(100)
# allow user to click
# for some action
turtle.onclick(fxn)
Output :
Example 2 :
# 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()
Output :
