Python GUI Program: Creating a tabbed interface with Tkinter

Last update on August 25 2025 12:34:43 (UTC/GMT +8 hours)

Write a Python GUI program to create a Notebook (tabbed interface) with three tabs, each containing different content using tkinter module.

Sample Solution:

Python Code:

import tkinter as tk
from tkinter import ttk

def create_tab1(tab):
    label = ttk.Label(tab, text="Java Exercises")
    label.pack(padx=20, pady=20)

def create_tab2(tab):
    label = ttk.Label(tab, text="Python Exercises")
    label.pack(padx=20, pady=20)

def create_tab3(tab):
    label = ttk.Label(tab, text="C++ Exercises")
    label.pack(padx=20, pady=20)

def main():
    parent = tk.Tk()
    parent.title("Tabbed Interface")
    notebook = ttk.Notebook(parent)

    # Create and add tabs
    tab1 = ttk.Frame(notebook)
    tab2 = ttk.Frame(notebook)
    tab3 = ttk.Frame(notebook)    

    notebook.add(tab1, text="Java")
    notebook.add(tab2, text="Python")
    notebook.add(tab3, text="C++")

    create_tab1(tab1)
    create_tab2(tab2)
    create_tab3(tab3)

    notebook.pack(padx=10, pady=10, fill="both", expand=True)

    parent.mainloop()

if __name__ == "__main__":
    main()

Explanation:

In the exercise above -

First we create three functions (create_tab1(), create_tab2(), and create_tab3()) that create content for each tab.
Next we create a tk.Tk() instance as the main window and a ttk.Notebook to hold the tabs.
Three tabs (tab1, tab2, and tab3) are created as ttk.Frame widgets and added to the notebook using the add method.
Each tab's content is created using the functions defined earlier.
The notebook is packed into the main window, and the main event loop is started with parent.mainloop().
