Hello,

I trying to make this piece of code work (this is python3)

from tkinter import *
from tkinter.ttk import *

class Window:
def __init__(self):
self.root = Tk()

self.menu = Menu(self.root)
self.root['menu'] = self.menu

self.submenu = Menu(self.menu)
self.ck = 0
self.submenu.add_checkbutton(label="My checkbutton",
variable=self.ck, command=self.displayCK)
self.menu.add_cascade(label="sub", menu=self.submenu )

def displayCK(self):
print( self.ck )


app = Window()
app.root.mainloop()


The self.ck will always be 0... why?

Dorian
