turtle.onclick() function in Python
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) |
