Tkinter - How to create a combo box with autocompletion

Question

Is it possible to create a combobox that updates with the closest item in its list as you type into it?

For example:

A = ttk.Combobox()
A['values'] = ['Chris', 'Jane', 'Ben', 'Megan']

Then you type "Chr" into the combobox, I want it to automatically fill in "Chris".

Answer 1

Yes, it can be easily done using the following example, taken from here:

from ttkwidgets.autocomplete import AutocompleteEntry
from tkinter import *

countries = [
        'Antigua and Barbuda', 'Bahamas','Barbados','Belize', 'Canada',
        'Costa Rica ', 'Cuba', 'Dominica', 'Dominican Republic', 'El Salvador ',
        'Grenada', 'Guatemala ', 'Haiti', 'Honduras ', 'Jamaica', 'Mexico',
        'Nicaragua', 'Saint Kitts and Nevis', 'Panama ', 'Saint Lucia', 
        'Saint Vincent and the Grenadines', 'Trinidad and Tobago', 'United States of America'
        ]

ws = Tk()
ws.title('PythonGuides')
ws.geometry('400x300')
ws.config(bg='#f25252')

frame = Frame(ws, bg='#f25252')
frame.pack(expand=True)

Label(
    frame, 
    bg='#f25252',
    font = ('Times',21),
    text='Countries in North America '
    ).pack()

entry = AutocompleteEntry(
    frame, 
    width=30, 
    font=('Times', 18),
    completevalues=countries
    )
entry.pack()

ws.mainloop()
