[Tkinter] GUI Opens Minimized

[deanhystad]

Unless your "sanitizing" changed things, the blank window becomes what you refer to as the GUI. Remove the withdraw() and run your code. Does the blank window disappear when the GUI window appears?

I removed everything except the tkinter parts. When I run this I see the blank window for a flash then it disappears and the "Do Not Call Interface" window appears.

import tkinter as tk
from tkinter import ttk
 
def getPhoneTray():
    return "Name", "Number", "Date", "Time", "Appointment"
 
def center(win):
    """
    centers a tkinter window
    :param win: the main window or Toplevel window to center
    """
    win.update_idletasks()
    width = win.winfo_width()
    frm_width = win.winfo_rootx() - win.winfo_x()
    win_width = width + 2 * frm_width
    height = win.winfo_height()
    titlebar_height = win.winfo_rooty() - win.winfo_y()
    win_height = height + titlebar_height + frm_width
    x = win.winfo_screenwidth() // 2 - win_width // 2
    y = win.winfo_screenheight() // 2 - win_height // 2
    win.geometry('{}x{}+{}+{}'.format(width, height, x, y))
    win.deiconify()
