Tkinter main window becomes unresponsive after message box

Question

I have problem with Tkinter. After messagebox I can't edit Entry in main window. Below simply code with this problem. Can you help me?

from tkinter import messagebox, Entry, Tk


def pop_error():
    messagebox.showerror(message="Error")


win = Tk()
entry = Entry(win)
entry.grid()
pop_error()
win.mainloop()

Answer 1

Force the Entry to focus after closing the messagebox

from tkinter import messagebox, Entry, Tk

def pop_error():
    messagebox.showerror(message="Error")

win = Tk()
entry = Entry(win)
entry.grid()
pop_error()
entry.focus_force()
win.mainloop()
