So for the relevant code there is this
import tkinter as tk
from tkinter import ttk
import quiz
global menu_root
def get_question():
question_input = question_response.get()
answer_input = answer_response.get()
quiz.add_question(question_input, answer_input)
def question_menu():
menu_root = tk.Tk()
global question_response
global answer_response
menu_root.geometry("250x250")
menu_root.resizable(width=False, height=False)
menu_root.title("Add A Question!")
question_response = tk.StringVar()
answer_response = tk.StringVar()
tk.Label(menu_root, text="What question would you like to add?", font=("TkDefault", 10)).place(
x=15, y=25)
text1 = tk.Entry(menu_root,)
text1.place(x=15, y=45)
tk.Label(menu_root, text="What's the answer to the question?", font=("TkDefault", 10)).place(
x=15, y=60)
text2 = tk.Entry(menu_root)
text2.place(x=15, y=80)
tk.Button(menu_root, text="Confirm?", font=("TkDefault", 10),
command=get_question).place(x=15, y=100)
menu_root.mainloop()
and
import tkinter as tk
from tkinter import ttk
import buttons
import quiz
def add_button_gui():
buttons.question_menu()
def dev():
print(quiz.Quiz.questions)
print(quiz.Quiz.answers)
def main_gui():
main_root = tk.Tk()
main_root.resizable(width=False, height=False)
main_root.geometry("500x500")
main_root.title("Pyquiz")
main_window = tk.Frame(main_root, borderwidth=5, relief="raised")
main_label = tk.Label(main_root, text="PyQuiz", font=("TkDefault", 35)).place(x=165, y=0)
add_button = tk.Button(main_root, text="Add A Question", font=("TkDefault", 25), command=add_button_gui).place(x=125, y=115)
remove_button = tk.Button(main_root, text="Remove Latest Question", font=("TkDefault", 25)).place(x=70, y=200)
test_button = tk.Button(main_root, text="Test Your Knowledge", font=("TkDefault", 25)).place(x=90, y=285)
save_button = tk.Button(main_root, text="Save Questions", font=("TkDefault", 25)).place(x=110, y=375)
dev_button = tk.Button(main_root, text="DEVTEST", font=("TkDefault", 25), command=dev).place(x=100, y=450)
main_root.mainloop()
Now, what I want the code to do is open the second menu (menu_root) and have the user have 2 input slots which when the button is pressed it takes whatever string is in the input and adds it to a list I have in another script (quiz.Quiz.questions quiz.Quiz.answers). Apologies if this code is a bit sloppy but its my first real program i'm trying so its a W.I.P. If you have any criticization or suggestions feel free (though this is also simply for a computer science class final where I am trying way too hard for no reason)
also currently it just gives the error code of
Exception in Tkinter callback

CodePudding user response:
You have to use the StringVar object that you've created as the text variable holder:
text1 = tk.Entry(menu_root, textvariable=question_response)
and:
text2 = tk.Entry(menu_root, textvariable=answer_response)
And to use global the variable has to be introduced outside the function.
CodePudding user response:
I think I was able to get the code currently in your question (using two Tk()
s) working by changing how the StringVar
s are created and adding a reference to them when the two Entry
widgets are created. I've indicated the important changes in the code below with <-- CHANGED
comments. Note I disabled references to the quiz
module since you didn't provide the code for it in your question.
