How do I hide the entire tab bar in a tkinter ttk.Notebook widget?

Question

How do I hide the tab bar in a ttk Notebook widget? I don't want to hide the frame that belongs to the tab. I just want to remove the tab bar from sight, even where it's not at the top of the screen (for more than one purpose).

Anyway, it would be nice for fullscreen mode.

from the help on tkinter.ttk.Style:

layout(self, style, layoutspec=None)

Define the widget layout for given style. If layoutspec is omitted, return the layout specification for given style.

layoutspec is expected to be a list or an object different than None that evaluates to False if you want to "turn off" that style.

try this:

import tkinter as tk
from tkinter import ttk

root = tk.Tk()

style = ttk.Style()

style.layout('TNotebook.Tab', []) # turn off tabs

note = ttk.Notebook(root)

f1 = ttk.Frame(note)
txt = tk.Text(f1, width=40, height=10)
txt.insert('end', 'Page 0 : a text widget')
txt.pack(expand=1, fill='both')
note.add(f1)

f2 = ttk.Frame(note)
lbl = tk.Label(f2, text='Page 1 : a label')
lbl.pack(expand=1, fill='both')
note.add(f2)

note.pack(expand=1, fill='both', padx=5, pady=5)

def do_something():
    note.select(1)
               
root.after(3000, do_something)
root.mainloop()
