Tk window randomly opening along with CTkInputDialog

Question

For this code:

import customtkinter as ctk
import tkinter

ctk.set_appearance_mode("dark")
dialog = ctk.CTkInputDialog(text="Type in a number:", title="Test")
print("Number:", dialog.get_input())

The desirable output is CtkInputDialog Box which asks me the number and prints it in the console. However while running the code. A Tkinter Windows opens alongside. It cannot be closed and closes automatically when CtkInputDialog Box is closed or the code finishes execution. This code is from the Ctk documentations

Answer 1

Every tkinter application requires a root window. If you don't create one explicitly then one will be created the first time you create any other widget.

In this case, you aren't creating a root window so one is being created for you.

You should explicitly create a root window. If you don't want it to be visible you can hide it.

import customtkinter as ctk
import tkinter

root = ctk.CTk()
root.withdraw()
ctk.set_appearance_mode("dark")
dialog = ctk.CTkInputDialog(text="Type in a number:", title="Test")
print("Number:", dialog.get_input())
