OOP in Tkinter - Create Frame with Listbox

Hey I would like to create a frame which contains a Listbox and some buttons. What I would like to do is to somehow pass as an argument a name of this listbox. This is my current code in which I set the name of this listbox to master.thisListbox but I would like to pass it somehow as argument. Is it possible or should I separately crate a listbox in my App and the pass it as an argument to a frame? I'm going to create a lot of such listboxes in my App hence the name of listbox shouldn't be the same. I'm pretty new in OOP.
class myApp(tk.Tk):
def __init__(self):
tk.Tk.__init__(self)
self.dateFrame = DateFrame(self)
self.dateFrame.grid(row = 0, column = 0)
print(self.day.get())
self.myFrame = ListboxFrame(self, "Label!", [1,2,3])
self.myFrame.grid(row = 1, column = 0)
x = self.thisListbox.get(0, END)
print(x)
class DateFrame(ttk.Frame):
def __init__(self, master):
ttk.Frame.__init__(self, master)
# Day
ttk.Label(self, text = "Day", width = 4).grid(row = 0, column = 0, padx = 3, pady = 3)
master.day = IntVar(master, value = 31)
self.dayCB = ttk.Combobox(self, values = [x for x in range(1, 32)], textvariable = master.day, width = 4)
self.dayCB.grid(row = 1, column = 0, padx = 3, pady = 3)
# Month
ttk.Label(self, text = "Month", width = 6).grid(row = 0, column = 1, padx = 3, pady = 3)
self.month = IntVar(master, value = 12)
self.monthCB = ttk.Combobox(self, values = [x for x in range(1, 13)], textvariable = self.month, width = 4)
self.monthCB.grid(row = 1, column = 1, padx = 3, pady = 3)
# Year
ttk.Label(self, text = "Year", width = 4).grid(row = 0, column = 2, padx = 3, pady = 3)
self.year = IntVar(master, value = 2021)

master.thisListbox = tk.Listbox(self, selectmode = selectmode, height = height, width = width)

Grid_forget() doesn't seem to forget widgets

I have a problem regarding tkinter's grid_forget() method. I have 2 pages in a notebook and I want to show certain widgets on the second page based off the user's selected options in the first page, I have a multiple choice menu and the grid_forget() method seems to work well until I select 2 or more options from the menu. I tried creating the widgets when an option is selected and place them based on the choice, no luck there, also tried creating them with the rest of the widgets and when the user selected an option I would simply just use grid to place them on the screen, also no luck there. I created a demo below, sorry for potential mistakes.

Tkinter Get Value and then Destroy

I'm trying to create an app that has 2 windows. The first window (A) is only called the first time the app is ran, and then opens window (B). For all future events, only window (B) is called. This is the following code:
# Script Counter/Setup
def read_counter():
if path.exists("counter.json"):
return loads(open("counter.json", "r").read()) + 1
else:
info = tk.Tk()
info.title("Setup")
info.geometry("350x120")
info.grid_columnconfigure((0, 2), weight = 1)
count = tk.Label(info, text = "Previous Post Number")
string = tk.StringVar()
count_input = tk.Entry(info, textvariable = string)
val = string.get()
def destroy_get():
val = int(count_input.get())
info.quit()
return val
count_button = tk.Button(info, text = "Done!", command = destroy_get)
tk.Label(info, text = "Setup", font='Helvetica 18 bold').grid(row = 0, column = 1, padx = 5, pady = 5)
count.grid(row = 1, column = 0, padx = 5, pady = 5)
count_input.grid(row = 1, column = 2, padx = 5, pady = 5)
count_button.grid(row = 2, column = 1, padx = 5, pady = 5)
info.mainloop()
# info.destroy()
return destroy_get()
def write_counter():
with open("counter.json", "w") as f:
f.write(dumps(counter))
counter = read_counter()
atexit.register(write_counter)
folders = ["to_post/", "not_posted/", "posted"]
for folder in folders:
if not path.exists(folder):
os.mkdir(folder)
print(os.getcwd())
# GUI
window = tk.Tk()
window.title("Confessions Bot")
window.geometry("600x350")
window.grid_columnconfigure((0,2), weight = 1)
label_tell_account = tk.Label(window, text = "Tellonym Account")
label_tell_password = tk.Label(window, text = "Tellonym Password")
label_ig_account = tk.Label(window, text = "Instagram Account")
label_ig_password = tk.Label(window, text = "Instagram Password")
tell_account = tk.Entry(window)
tell_password = tk.Entry(window)
ig_account = tk.Entry(window)
ig_password = tk.Entry(window)
image = ImageTk.PhotoImage(Image.open("logo.png"))
tk.Label(window, image = image).grid(row = 0, column = 1, padx = 10, pady = 10)
label_tell_account.grid(row = 1, column = 0)
tell_account.grid(row = 1, column = 2, padx = 10, pady = 10)
label_tell_password.grid(row = 2, column = 0, padx = 10, pady = 10)
tell_password.grid(row = 2, column = 2, padx = 10, pady = 10)
label_ig_account.grid(row = 3, column = 0, padx = 10, pady = 10)
ig_account.grid(row = 3, column = 2, padx = 10, pady = 10)
label_ig_password.grid(row = 4, column = 0, padx = 10, pady = 10)
ig_password.grid(row = 4, column = 2, padx = 10, pady = 10)
# run.grid(row = 5, column = 1, padx = 10, pady = 10)
window.mainloop()
When this is ran I get _tkinter.TclError: image "pyimage1" doesn't exist. I read that this happens since I haven't destroyed my initial window. If I change destroy_get() to have info.destroy() I'm no longer able to get the the entry from window A.
This is my first time using Tkinter and coding in general so any help is welcome.

tkinter NavigationToolbar2Tk with matplotlib disappears

Good afternoon,
I've been trying for two days to solve this problem and desperate, I am looking for your help. I want to show a plot (using matplotlib) within my tkinter application (not opening it in a different window) and the problem is that when I press any of the toolbar buttons as soon as I cross with the mouse coursor the lines of the plot, the plot disappears for a brief moment and appears again, but the toolbar buttons disappear until I cross them again with the mouse coursor. So for the button to appear back I should cross it and cross out off the button.
I noticed that if I change the background image (just the color, placed in label) the disappeared buttons are replaced with that color, so it seems that when I cross the lines of the plot everything in the Label except the plot is overlayed by the background.
Regards,
Wladyslaw

how to return a value to the main function after clicking a button in tkinter?

In this file, I tried to return the value of employNum and employPass to the main function each time I clicked the display button. How can I do that?
from tkinter import *

Label(root,text = employNum.get() ).grid(row = 3, column = 1, sticky = N+S+W+E)
Label(root, text = employPass.get()).grid(row = 4, column = 1, sticky = N+S+W+E)

Label(root, text = 'Login Password: ').grid(row = 1, column = 0, sticky = W)
employeeNum = StringVar()
employeePass = StringVar()
Entry(root, textvariable = employeeNum).grid(row = 0, column = 1, columnspan = 2, sticky = W)
Entry(root, textvariable = employeePass).grid(row = 1, column = 1, columnspan = 2, sticky = W)
checkButton = BooleanVar()
Checkbutton(root, text = 'Remember Me', variable = checkButton).grid(row = 2, column = 1, sticky = W)
Button(root, text = 'Save', relief = RAISED).grid(row = 2, column = 2, sticky = E)
display = Button(root, text = 'Display', relief = RAISED, command = lambda: displayButton(root, employeeNum,employeePass))

Button can't return value using return. You can only set value in global variable or passed as argument. You can change text in Label assigned to global variable or passed as argument. You can create new Label but root have to be global variable or passed as argument.
