Python, currently one of THE most popular languages, is immensely feature-rich and capable. It offers several potent options for developing top-tier graphical user interfaces, the chief among which is Tkinter. A standard Python interface, the Tkinter package comes included with every Python installation and is the most commonly used interface/package/library for GUI coding.

Graphical user interfaces are all around us. Every online, mobile, or desktop application we interact with has a GUI, a set of graphical elements with in-built functions that facilitate interactions with any digital system. GUIs offer a visual, intuitive, and highly interactive medium for connecting & using any computer and IT resource and programmers need to possess a solid understanding of the underlying software architecture for determining the best approaches to easy and seamless interactions.
Tkinter, the most popular GUI interface, enables Python coders to design Windows with widgets. Here’s how it works.
- Generic GUIs are developed by arranging & merging different widgets on a screen.
- Tkinter comes shipped with every version of Python.
Let’s now dive a bit deeper into Python GUI coding with Tkinter.
Using Python & Tkinter For GUI Coding
Here’s an overview of simple Python GUI programming with Tkinter.
- Import the module/package/interface
- Build the primary window of the GUI (the main window is the container)
- Please enter the code for the primary window that keeps it up & open on loop, and the event triggers on to the widgets.
m= Tkinter.Tk(screenName = None, baseName= None, className=’Tk’, useTk=1)
The above method creates the main window. Coders can add names as they want. m is the object of the primary window.
Here’s a look at some basic code in Python 3. x versionsà
import tkinter // Tkinter for Python 2.x version
m=tkinter.Tk(..) // creates the main GUI window
//Widgets and elements are added here.
Do the above codes seem a bit too complicated? They are the bread and butter of Python GUI coding using Tkinter. If you have trouble understanding Python & Tkinter coding, look for online programming assignment help urgently.
Widgets, The Bread & Butter of Python GUI Programming
Each component is a self-contained widget component that can be easily integrated with a GUI main window.
Here’s a look at them:
- Button à This widget displays buttons in the application window
- Canvas à A widget to draw different kinds of shapes, lines, polygons, etc. in the application
- Check button à Used to display options as checkboxes; allows selection of multiple options at a time
- Entry à Display a single-line text field for accepting user values
- Title à Adds a title to the main window
- Frame, Label, resizable, Listbox, Menu button, Menu, etc.– there are numerous different kinds of widgets & features available on Tkinter that can be easily integrated with the GUI window.
Here are some more code snippets to help you give some ideas:
Import Tkinter as tk
win.Title(“ My First Tk GUI”)
Want to change the size of the main GUI window? Here’s the code à
import Tkinter as tk
win.title(“The First Tk GUI by Me”)
More About Programming
Widgets in Tkinter can be categorized according to specific classes. The most common classes of widgets available are:
- Label = A class of widgets used to display any text or image in the main window’s display. The displayed content can be changed at any time during coding, and specific parameters can be set to change the widget’s format.
The general syntax is as follows à w=Label(master, text=’..’) // master is the main GUI window where the text is entered
Intresting Facts About Programming
- Button = Button widgets contain text and perform some action when clicked. It offers several options to change the foreground & background color, the command to be triggered, the font of the text on the button label, and changing the image, width, or height.
The general syntax is à
- Entry = Widget for entering a single line of text and offers the option to change the border width of the entry box, the background color, cursor, command, width & height, the function to be called, changing the width, height, etc.
The general syntax is à Label (master, text=’First Name’).grid(row=0)
Label (master, text=’Last Name’).grid(row=1)
- Frame = A container for holding, grouping, and organizing all different widgets. Allows coders to change different aspects & parameters of the frame
The general syntax is à Frame (master, parameter options)
- Tkinter offers a vast array of GUI elements & widgets for developing versatile, multi-purpose user interfaces.
We wrap up this write-up with a look at some other GUI programming interfaces in Python.
Two More Powerful GUI Interfaces For Python
Built around the Qt framework, PyQt5 boasts cross-platform compatibility and is used to create varied applications across different platforms. It leverages the power of the Qt framework and allows developers to build applications for platforms like Windows, Mac, Linux, iOS, Android, etc. PyQt5 has a vast arsenal for developers to implement with simple drag and drop.
Kivy is an open-source framework built on Python & Cython. It enables developers to craft intuitive user interfaces and even integrate multi-touch applications using Natural User Interfaces. The Kivy GUI framework finds widespread usage in Android & iOS app UI designing. Other major implementations involve designing interfacing elements in Linux, Windows, Raspberry Pi, and macOS.
Well, that’s all the space we have for today. Hope this write-up was an exciting and informative read. Practice more and more to improve your GUI coding skills in Python and if need be, avail the services of a reputed online programming assignment help.
