from tkinter import *
root = Tk()
root.overrideredirect(True) # turns off title bar, geometry
root.geometry('400x100+200+200') # set new geometry

# make a frame for the title bar
title_bar = Frame(root, bg='#2e2e2e', relief='raised', bd=2,highlightthickness=0)

# put a close button on the title bar
close_button = Button(title_bar, text='X', command= root.destroy,bg = "#2e2e2e",padx = 2,pady = 2,activebackground='red',bd = 0,font="bold",fg='white',highlightthickness=0)

# a canvas for the main area of the window
window = Canvas(root, bg='#2e2e2e',highlightthickness=0)

# pack the widgets
title_bar.pack(expand=1, fill=X)
close_button.pack(side=RIGHT)
window.pack(expand=1, fill=BOTH)
xwin=None
ywin=None
# bind title bar motion to the move window function

def move_window(event):
    root.geometry('+{0}+{1}'.format(event.x_root, event.y_root))
def change_on_hovering(event):
    global close_button
    close_button['bg']='red'
def return_to_normalstate(event):
    global close_button
    close_button['bg']='#2e2e2e'
    
    
title_bar.bind('<B1-Motion>', move_window)
close_button.bind('<Enter>',change_on_hovering)
close_button.bind('<Leave>',return_to_normalstate)
root.mainloop()
