make Tab key do 4 space instead 8 in textbox tkinter

I'm trying to create a text editor with tkinter When I click on the Tab key on the keyboard it does 8 spaces I want it to do only 4 spaces instead of 8 code:

import tkinter as tk

root = tk.Tk()
root.title('Text editor')

text = tk.Text(root)
text.pack()


root.mainloop()
Solution

  • Try this:

    import tkinter as tk

def tab_pressed(event:tk.Event) -> str:
    # Insert the 4 spaces
    text.insert("insert", " "*4)
    # Prevent the default tkinter behaviour
    return "break"

root = tk.Tk()

text = tk.Text(root)
text.pack()
text.bind("<Tab>", tab_pressed)

root.mainloop()

    I used .bind and return "break" to add my own functionality for when the tab key is pressed while blocking tkinter's default behaviour.

    If you just want the tabs to be 4 spaces wide, look here.
