Wie erhalte ich den Wert eines Artikels in tkinter, wenn ich eine Klasse verwende?

Question

Ich wollte ein bisschen Tkinter lernen. Ich folgte ein paar Guides von sentdex auf Youtube und fühle mich wie ich ein gutes Verständnis der Grundlagen habe. Jetzt versuche ich jedoch, ein Skript zu schreiben, das als schnelles Protokoll funktioniert, und ich stehe auf Probleme, den Text aus dem Eintrag/text/optionmenu zu bekommen.

Wenn ich die GUI außerhalb der Klasse einrichten, kann ich einfach eine variable.get() und alles ist ducky. Aber wenn ich meine gui tkinter Sachen in einer Klasse habe, bekomme ich eine Ausnahme, die nicht definiert ist.

Hier ist mein Code. Das Problem liegt in def saveButtonCommand (self):

Wie bekomme ich die Werte von noteText und officeOption/Var?

Nun, ich regelte es, sollten Sie selbst benutzen. „Variablenname“ ein zugängliches Attribut zu deklarieren.

from tkinter import * 
from tkinter import messagebox 
import sys, datetime 

class Window(Frame): 

def __init__(self, master = None): 
    Frame.__init__(self, master) 
    self.master = master 
    self.init_window() 

def init_window(self): 
    self.master.title("SPL - " + str(datetime.date.today())) 
    self.configure(background="#e7e7e7") 
    self.pack(fill=BOTH, expand=1) 

    # Menu -> Quit, Open Log 

    menu = Menu(self.master) 
    self.master.config(menu=menu) 

    file = Menu(menu) 
    file.add_command(label="Open Log") 
    file.add_command(label="Quit", command=self.client_exit) 
    menu.add_cascade(label="File", menu=file)
