Saving a kivy widget to a file

Question

So I\'m trying to save a kivy widget to a file using cpickle and I get an error.

from kivy.uix.widget import Widget
import cPickle as pickle

foo = Widget()
         


        

Answer 1

Looks like using higher protocol may help:

#!/usr/bin/python
# -*- coding: utf-8 -*-

try:
    import cPickle as pickle
except:
    import pickle

from kivy.uix.widget import Widget

w = Widget()
w.test = 5
data_string = pickle.dumps(w, protocol=pickle.HIGHEST_PROTOCOL)

x = pickle.loads(data_string)
print x.test
