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 :
Python3
# 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 :
Python3
# 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 :
