I can't hide borders and _ [] X in window.

[storzo]

I try using: main.pack(side="top", fill="both", expand=True)
in main window to hide borders and nav minimalize expand and close.
It don't work any suggestion?

import tkinter as tk
import pyautogui

class MainWindow():
    def __init__(self, root):
        self.root = root

        self.pole = tk.Label(self.root, text="---------")
        self.pole.place(x=0, y=0)

        self.move()
    def move(self):

         # information uder mouse
        x, y = pyautogui.position()
        pixelColor = pyautogui.screenshot().getpixel((x, y))
        self.pole.config(text="X:" + str(x) + " Y:" + str(y) + "\n R:" + str(pixelColor[0]).rjust(3) + " G:" + str(
            pixelColor[1]).rjust(3) + " B:" + str(pixelColor[2]).rjust(3))
        x = x + 2
        y = y + 1
        loc = "150x45+" + str(x) + "+" + str(y)
        root.geometry(loc)
        root.attributes("-topmost", True, "-toolwindow", True, "-alpha", 0.7)
        root.after(5, self.move)




root = tk.Tk()
main = MainWindow(root)

#main.pack(side="top", fill="both", expand=True)
root.mainloop()
