Found buttonstate in tabs

[MacTommu]

Is a total beginner when it comes to Python and Tkinter. I have programmed a lot of C # and VB over the years and thought of learning a litle Python for a project. It's progressing slowly and the code can be optimized, I know, but one thing at a time. :)

I want to make an app with 4 tabs. On each side I will have a bunch of buttons, a total of 50 on different tabs. I want the buttons as arrays when they send a UDP command where a group value is changed. So I do not want to build 50 functions that take care of each button, but have a general function. I'am also building a function that collect my buttons information from a Helvar router so they update when we turn on lights from a button outside this "app".

When I use without tabs, it works the way I want with:

     button = buttons [int (i)]
     if button ['relief'] == 'raised':

When I use tabs, I can't find my button. "TypeError: 'NoneType' object is not subscriptable"

I don't need someone that rewrite my code, I only need to knew if it's possible and some hint what to search on net to found a solution. If you get everything served, you do not learn, but it can help to be pushed in any direction. :)

My test code scaled down:

from tkinter import *
from tkinter import ttk
import tkinter as tk

def on_tab_selected(event):
    global selected_tab 
    selected_tab = event.widget.select()
    print(selected_tab)

root = tk.Tk()
root.title("MainWindow")
root.geometry("800x480")
root.configure(bg='black')

tabControl = ttk.Notebook(root)
tabControl.grid(row=1, column=0, columnspan=50, rowspan=49, sticky='NESW')

s = ttk.Style()
s.configure('TNotebook.Tab', font=('Helvetica','15','bold') )

tab1 = ttk.Frame(tabControl)
tab2 = ttk.Frame(tabControl)
tab3 = ttk.Frame(tabControl)
tab4 = ttk.Frame(tabControl)

tabControl.bind("<<NotebookTabChanged>>", on_tab_selected)

tabControl.add(tab1, text =' Start ')
tabControl.add(tab2, text =' Arbetsljus ')
tabControl.add(tab3, text =' Blåljus ')
tabControl.add(tab4, text =' Övrigt ')

tabControl.pack(expand = 1, fill ="both")
