You probably defined a function cercle
that draws French circles.
The function should look like:
def cercle(canv, x, y, rad):
return canv.create_oval(x-rad, y-rad, x+rad, y+rad, width=2)
Note that the function must return the circle object. Otherwise self.ouvre
is None and then you can not delete it as you do not have a reference to the object in self.can.delete(self.ouvre)
.
Tested with python 3.2 in windows 7 64bit
solved Unexpected results with delete method
