QUIZ GUI Form_When admin panel is open, main quiz form is getting freeze

[Uday]

Hi Expert,

I have already created one QUIZ GUI application where user can select option and click on submit button to check the score. One ADMIN button is also placed to open the ADMIN PANEL, but when the admin panel is open, both the main quiz form and admin panel is getting freezed.

I have already attached the .py file, please see it and suggest.

Regards,
Uday

I have removed it, still it is getting freezed, if the admin panel is open. I have tested in my system. I have attached the latest file.

Don't attach, post your your code using the python button (insert python).

Not letting the top window lose focus is what causes the problem. Why are you doing that?

This is as short an example I can come up with that demonstrates the problem.

import tkinter as tk
from tkinter import simpledialog


class TopmostForm:
    def __init__(self, root):
        self.root = root
        self.admin_button = tk.Button(self.root, text="Admin", command=self.admin_access)
        self.admin_button.pack()
        self.root.bind("<FocusOut>", self.on_focus_out)
        
    def on_focus_out(self, event):
        """comment out following line and problem goes away"""
        self.root.focus_force()

    def admin_access(self):
        simpledialog.askstring("Admin Access", "Enter admin password:")
            

if __name__ == "__main__":
    root = tk.Tk()
    app = TopmostForm(root)
    root.mainloop()

I would get rid of the code that tries to keep focus on the top window. It is causing a problem, and it doesn't keep focus on the top window anyway.
