Signature de la méthode onrelease

def onrelease(self, fun, btn=1, add=None) 

Description

help(RawTurtle.onrelease)

Bind fun to mouse-button-release event on this turtle on canvas.

        Arguments:
        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).

        Example (for a MyTurtle instance named joe):
        >>> class MyTurtle(Turtle):
        ...     def glow(self,x,y):
        ...             self.fillcolor("red")
        ...     def unglow(self,x,y):
        ...             self.fillcolor("")
        ...
        >>> joe = MyTurtle()
        >>> joe.onclick(joe.glow)
        >>> joe.onrelease(joe.unglow)

        Clicking on joe turns fillcolor red, unclicking turns it to
        transparent.
