The following program behaves differently under Python 3.6:
'''
checkbutton test
'''
import tkinter
class GUI(tkinter.Tk):
def __init__(self):
tkinter.Tk.__init__(self)
frame = tkinter.Frame(self)
for tag in ('A', 'B'):
w = tkinter.Checkbutton(frame, text=tag)
w.pack(side='top', padx=10, pady=10)
print(w)
frame.pack(side='top')
frame = tkinter.Frame(self)
for tag in ('C', 'D'):
w = tkinter.Checkbutton(frame, text=tag)
w.pack(side='top', padx=10, pady=10)
print(w)
frame.pack(side='top')
gui = GUI()
gui.mainloop()
Selection of button 'A' also selects button 'C'. Same goes for 'B' and 'D'.
I noticed that widget names have changed, which likely leads to the cause:
> /usr/local/Python-3.5.1/bin/python3 foo.py
.140182648425776.140182647743208
.140182648425776.140182647841848
.140182648424152.140182648282080
.140182648424152.140182648282136
> /usr/local/Python-3.6.0/bin/python3 foo.py
.!frame.!checkbutton
.!frame.!checkbutton2
.!frame2.!checkbutton
.!frame2.!checkbutton2
Is this a known issue?
