Combobox haqida qisqacha: 
tkinter da Combobox elementini (Ro'yxat tanlov oynasi) yaratish uchun, 
ttk 
(themed tkinter) modulini ishlatishingiz mumkin. Quyidagi kodni ko'rib 
chiqaylik:
import tkinter as tk

from tkinter import ttk
def tanlov_oyincha(*args):
tanlov_tekshir.set("Siz " + tanlov_var.get() + "ni tanladingiz.")
# Asosiy oynani yaratamiz
oyna = tk.Tk()
oyna.title("Tkinter Combobox Misoli")
# Tanlov uchun ro'yxatni tuzamiz
tanlov_var = tk.StringVar()
tanlov = ttk.Combobox(oyna, textvariable=tanlov_var)
tanlov["values"] = ("Variant 1", "Variant 2", "Variant 3", "Variant 4")
tanlov.grid(column=0, row=0, padx=10, pady=10)
tanlov.current(0) # Boshlang'ich tanlovni tanlash
# Tanlovni tekshiruvchi Label
tanlov_tekshir = tk.StringVar()
tanlov_tekshir_label = ttk.Label(oyna, textvariable=tanlov_tekshir)
tanlov_tekshir_label.grid(column=1, row=0, padx=10, pady=10)
# Tanlov o'zgarganda tanlov_oyincha funksiyasini chaqirish
tanlov_var.trace("w", tanlov_oyincha)
# Tkinter hodisalarini boshlaymiz
oyna.mainloop()

Dasturimizga 
run
berganimizdan sahifada ko’rishingiz mumkin bo’lgan 
oyna quyidagidan iborat 
Quyidagi oynada ttk kutubxonasidan treeview elementi chaqirib olingan 
Undagi heading lar (id , ism ,tashkilot , manzil , telefon )
Agarda biz “Add ” tugmasini bosganimizda quyidagi oyna hosil bo’ladi 
Tashkilotga xodim qo’shish oynasida foydalanuvchi telefon raqamlari , 
ismini va boshqa malumotlarini kiritishi mumkin .
Tashkilot nomi degan joyiga etibor bersak “+” tugmachasi bor bu 
tugmani bosib tashkilot nomini kiritishimiz mumkin . “+” tugmasi 
bosilganda quyidagi oyna hosil bo’ladi

Kod Tuzilishi:
Kodni o'qib yozish va saqlashga oson bo'lishi uchun uni kichik 
funksiyalarga yoki klasslarga ajratish yo’lidan foydalandim . Bu, kodni 
tushunish va yaxshi o'zgartirish uchun yordam bera olishi mumkin.
Foydalanuvchi Interfeysi Yaxshilanishi:
Umumiy foydalanuvchi interfeysni yaxshilash uchun, foydalanuvchiga 
qanday qilib ishlashini yaxshi tushuntirish uchun yorliqlar yoki boshqa 
elementlarni qo'shish mumkin.
Ma'lumotlar Bazasini Yopish:
Dastur yakunlanishida ma'lumotlar bazasini yopish juda muhim. Bu 
uchun oynaga yopish hodisalarga bog'langan metod yozish yaxshi 
bo'ladi.
