In the standard turtle module, when a turtle has a custom shape of type "compound", it doesn't to respond to click events. No problem with polygon shapes.
Observed on Windows XP, python 3.2.3, turtle version 1.1b, and on Linux, python 2.7.
Test code:
##################################################
import turtle
square = ((0,0),(0,20),(20,20),(20,0))
turtle.addshape("sq1", square) # sq1 = polygon shape
s = turtle.Shape("compound")
s.addcomponent(square, "red")
turtle.addshape("sq2", s) # sq2 = compound shape
t1 = turtle.Turtle(shape="sq1")
t2 = turtle.Turtle(shape="sq2")
t2.fd(20)
def click(x,y): print("click at",x,y)
t1.onclick(click)
t2.onclick(click)
turtle.mainloop()
##################################################
When you click on the black square (i.e. t1), the message "click at..." is printed. When you click on the red square (i.e. t2), nothing happens. |
