A Comprehensive Tkinter Tutorial For 2021

Introduction

Welcome to the Tkinter tutorial. Python offers many options for building GUI (Graphical User Interface). From all the GUI modules, Tkinter is used the most commonly. It is a paradigm Python to the GUI toolkit with Python. Python with Tkinter is the easiest and fastest way to make GUI applications. To create a GUI by using Tkinter is a trouble-free task. Python has a bunch of GUI frameworks, but Tkinter is the one and only structure that’s made into the Python model library.

Tkinter has much strength. It has cross-platform benefits, so the same code works on macOS , Linux, and Windows. Optical elements are provided using local operating system elements, so applications made with Tkinter appear as they befit in the platform where they’re run.

In this article about Tkinter Tutorial, let us look at:

1. What is a Graphical User Interface?
2. Python Library to Create Graphical User Interfaces (GUI)
3. What Is Tkinter?
4. Fundamentals of Tkinter
5. Tkinter Widgets
6. Geometry Management
7. Organizing Layouts and Widgets
8. Binding Functions

1. What is a Graphical User Interface?

To kick off this Tkinter tutorial, we must first understand the concept of a GUI.

Graphical User Interface (GUI) is a type of user interface that permits users to interact with electronic devices with the help of graphical icons and an audio indicator such as basic notation, instead of text navigation, text-based user interfaces, or typed command labels.

Graphical User Interface is a desktop application that facilitates users to connect and work with the computers. They perform diverse tasks on laptops, desktops, and other electronic devices.

GUI apps like Text-Editors read, create, delete and update different kinds of files.

Games like Chess, Solitaire, and Sudoku are apps in which you can play. GUI applications like Firefox, Microsoft Edge, and Google Chrome to surf through the Internet. There are many different types of GUI applications which we use daily on desktops or laptops.

2. Python Library to Create Graphical User Interfaces (GUI)

Python has many libraries and these four stand tall when it comes to Graphical User Interfaces . They are as follows:

• Kivy
• Python QT
• wxPython
• Tkinter

Out of these, Tkinter is the foremost choice for many developers and learners just because of its simplicity and ease of use.

3. What Is Tkinter?

Tkinter is an ingrained Python module which used to make simple GUI applications. Tkinter is the widely popular module for GUI applications in Python.

4. Fundamentals of Tkinter

Continuing this Tkinter tutorial, let’s first look at the fundamentals:

Creating a Graphical User Interface application using Tkinter is an easy task. One needs to carry out the following steps −

• Importing the Tkinter module.
• Creating the GUI application main window.
• Adding one or more of the aforementioned widgets to the Graphical User Interface application.
• Entering the major event loop for taking action against every event triggered by the users.

5. Tkinter Widgets

Widgets are something like fundamentals in the HTML. You will find different kinds of widgets to the different kinds of elements in the Tkinter.

• Button – Button widget is used to place the buttons in the Tkinter.
• Canvas – Canvas is acclimated to portray shapes in your GUI.
• Check button – The check button is used to make the check buttons in the application.
• Frame – Frame is used as containers in the Tkinter.
• Entry – Entry widget is acclimated to make input fields in the Graphical User Interface.
• Menu – Menu is used to make menus in the Graphical User Interface.
• Label – Label is acclimated to make single line widgets like images, text, etc.

These widgets are the grounds of the popularity of Tkinter. It makes it simple to understand and utilize it practically.

6. Geometry Management

All Tkinter widgets have admittance to specific geometry management methods, which have the reason of organizing widgets all through the parent widget area. Tkinter uses the following geometry manager classes: pack, place, and grid.

Every widget in the Tkinter will have some geometric measurements. These dimensions give you to systematize the widgets and their parent windows, frames, and so on.

Tkinter has three Geometry Manager classes mentioned below:

• pack():- It classifies the widgets in the block, which means it involves the entire available width. It’s a standard method to show the widgets in the window.
• place():- It will place the widgets at a particular position where the user wants.
• grid():- It arranges the widgets in a table-like formation.

7. Organizing Layouts and Widgets

To organize the layout in the window, we will use Frame, class. 

Steps:-

The frame creates divisions in the window. One can align the frames as they like with the side parameter of the pack() method.

The button generates a button in the window. It captures several parameters like fg (Color of the text), bg (Background color), text (Value of the Button).

8. Binding Functions

The binding function is used to deal with the events. We can bind Python’s Functions and methods to an event as well as we can bind these functions to any particular widget.

Calling functions whenever an event occurs refers to a binding function.

Conclusion

This brings us to the end of this Tkinter tutorial. The concepts discussed in this tutorial should help you make your own GUI apps and add functionality to the same.

This will be very handy when you are trying to create a customized application with a GUI that suits your personal needs. Now, you should also be able to use these widgets and images to develop applications easily with the help of Python.

As established thoroughly in this Tkinter tutorial, it is exceptional for quick and small, GUI applications, and as it runs on many platforms than any other Python Graphical User Interfaces (GUI) toolkit, it is a very good choice where mobility is the main concern.
