Tkinter GUI Application Development Cookbook

Overview of this book

As one of the more versatile programming languages, Python is well-known for its batteries-included philosophy, which includes a rich set of modules in its standard library; Tkinter is the library included for building desktop applications. Due to this, Tkinter is a common choice for rapid GUI development, and more complex applications can benefit from the full capabilities of this library. This book covers all of your Tkinter and Python GUI development problems and solutions. Tkinter GUI Application Development Cookbook starts with an overview of Tkinter classes and at the same time provides recipes for basic topics, such as layout patterns and event handling. Next, we cover how to develop common GUI patterns, such as entering and saving data, navigating through menus and dialogs, and performing long-running actions in the background.You can then make your apps leverage network resources effectively and perform graphical operations on a canvas and related tasks such as detecting collisions between items. Finally, this book covers using themed widgets, an extension of Tk widgets that have a more native look and feel. Finally, this book covers using the canvas and themed widgets. By the end of the book, you will have an in-depth knowledge of Tkinter classes, and will know how to use them to build efficient and rich GUI applications.

Introduction

Like any other programming language, Python lets you divide a process execution into multiple units that can be performed independently in time, called threads. When you launch a Python program, it starts its execution in the main thread.

Tkinter's main loop must start from the main thread, which is responsible for handling all the events and updates to the GUI. By default, our application code, such as callbacks and event handlers, will also be executed in this thread.

However, if we launch a long running action in this thread, the main thread execution will block until this operation is completed, and therefore the GUI will freeze and not respond to user events.

In this chapter, we will cover several recipes to achieve responsiveness in our applications while separate actions occur in the background, and also take a look at how to interact with them.
