I'm trying to display/include a function display_srv on a click from the menu bar command and get values of each checkbox selected with the button Done

import tkinter as tk

import glob

from tkinter import *



def frame_1():

    print("frame 1!")

The function I tried to display in the frame:

def display_srv():

    frame_1 = root.LabelFrame(root, text="Liste Serveurs")

    frame_1.grid(row=0, sticky='ew', padx=20, pady=20, ipadx=5, ipady=5)

    path = '/home/lst/*.txt'

    files=glob.glob(path)

    count = 0

    for file in files:

        with open(file, 'r') as lst_file:

            for item in lst_file:

                lng = root.Checkbutton(frame_1, variable = item, text=item.rstrip()).grid(row=count//10, column=count%10)

                count += 1

Text file value:

item1

item2

item3

...

item100

The function to get values:

def getvalue():

    print(list(lng.values()))

The main script:

root = Tk()

menu = Menu(root)

root.geometry('700x500')

root.title("My menu")

root.config(menu=menu)

testpsimenu = Menu(menu)

menu.add_cascade(label="Test Menu", menu=testpsimenu, font=("Arial", 12))

testpsimenu.add_command(label="Select 1", font=("Arial", 10), command=frame_1)

testpsimenu.add_separator()

testpsimenu.add_command(label="Select 2", font=("Arial", 10), command=display_srv)



psimenu = Menu(menu)

menu.add_cascade(label="PSI Real", menu=psimenu, font=("Arial", 12))

psimenu.add_command(label="Select 1", font=("Arial", 10), command=frame_1)

psimenu.add_separator()

psimenu.add_command(label="Select 2", font=("Arial", 10), command=frame_1)



exitmenu  = Menu(menu)

menu.add_cascade(label="Exit", menu=exitmenu, font=("Arial", 12))

exitmenu.add_command(label="Exit", command=root.quit, font=("Arial", 10))



Button(root, text='Done', font=("Arial", 12), command=getvalue).pack(side=RIGHT)



mainloop()

This is the error, when I click on Select2 from the menu testpsi:

Exception in Tkinter callback

Traceback (most recent call last):

    frame_1 = root.LabelFrame(root, text="Liste Serveurs")

Many thanks for your help...

I can see 2 problems so far.

1. You need to use the tk. prefix on your widgets and not root.

Change these:

root.LabelFrame

root.Checkbutton

To these:

tk.LabelFrame

tk.Checkbutton

2. You need to define lng as a global variable so it can be used in your getvalue() function.

Add this line global lng to the top of display_srv() like this:

def display_srv():

    global lng

Let me know if you have any questions.
