I'm creating a GUI with widgets, buttons, tabs, notes, and eventually will control a servo motor. In this GUI, there is the option to take notes, I'm wanting to save all the conent of the GUI, including the notes, to reopen and continue later.
My code below is VERY crude... I'm new but I'm trying :) `
import tkinter
from tkinter import *
import tkinter as tk
from tkinter import ttk
from tkinter import filedialog
from tkinter import filedialog as fd
from tkinter.messagebox import showinfo
root = Tk()
root.title('Linear Motion System')
root.geometry("850x750")
# Below code is the tab structure of the GUI
##########################################################################################################
my_notebook = ttk.Notebook(root)
my_notebook.pack(pady=30)
my_frame1 = Frame(my_notebook, width=850, height=650, )
my_frame2 = Frame(my_notebook, width=850, height=650, )
my_frame3 = Frame(my_notebook, width=850, height=650, )
my_frame1.pack(fill="both", expand=1)
my_frame2.pack(fill="both", expand=1)
my_frame3.pack(fill="both", expand=1)
my_notebook.add(my_frame1, text="Testing")

` Thank you
I have setup a file dialog with "Open" "Save" and "Save As" and now I have to figure out how to correctly save the GUI.
