clicking on turtle

Discussion in 'Python' started by Nicolas Graner, Nov 6, 2012.

  1. I have a problem with the standard "turtle" module. When a turtle has
    a custom shape of type "compound", it doesn't seem to respond to click
    events. No problem with polygon shapes.

    Running python 3.2.3, turtle version 1.1b on Windows XP.

    Here is my test file:

    ##################################################
    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) # set the turtles side by side
    def click(x,y): print("click at",x,y)
    t1.onclick(click)
    t2.onclick(click)
    turtle.mainloop()
    ##################################################

    When I run this and click on the black square (i.e. t1), the message
    "click at..." gets printed on the console. When I click on the red
    square (i.e. t2), nothing happens.

    Bug or feature?
