Creating Interactive Python Applications with Tkinter

Written on

Introduction to Tkinter

Graphical user interfaces (GUIs) are ubiquitous in modern technology, allowing us to interact with electronic devices through various input methods such as buttons, text boxes, and multimedia displays. Tkinter is Python's built-in library that enables developers to create both simple and complex GUI applications. This library includes a range of components, including buttons, entry fields, text areas, menus, and scrollbars.

Basic Example: Creating a Simple Button

To illustrate Tkinter's functionality, let's begin with a straightforward example of creating a GUI that features a button.

#importing all the class methods from the Tkinter

from tkinter import *

# First, we need to create a root window for our elements.

root = Tk()

# The Tk() instance manages the root window and its components.

# Frame serves as a space to organize our elements.

frame = Frame(root)

frame.pack()

# Creating a button within the frame.

button = Button(frame, text='Hello World')

button.pack()

# Event loop that keeps the application running.

root.mainloop()

The mainloop() method is crucial as it keeps the Tkinter application running indefinitely until the user decides to close the window.

Enhancing the GUI: Window Title and Size

In this example, we will learn how to set the window's title and size using the geometry method.

#importing all the class methods from the Tkinter

from tkinter import *

# Initialize the root window.

root = Tk()

# Set the title of the window.

root.title("This is the title page")

# Define the window size (width x height).

root.geometry('400x300')

# Frame for organizing elements.

frame = Frame(root)

frame.pack()

# Creating a button inside the frame.

button = Button(frame, text='Hello World')

button.pack()

# Event loop to run the application.

root.mainloop()
