Tkinter GUI Programming by Example

Overview of this book

Tkinter is a modular, cross-platform application development toolkit for Python. When developing GUI-rich applications, the most important choices are which programming language(s) and which GUI framework to use. Python and Tkinter prove to be a great combination. This book will get you familiar with Tkinter by having you create fun and interactive projects. These projects have varying degrees of complexity. We'll start with a simple project, where you'll learn the fundamentals of GUI programming and the basics of working with a Tkinter application. After getting the basics right, we'll move on to creating a project of slightly increased complexity, such as a highly customizable Python editor. In the next project, we'll crank up the complexity level to create an instant messaging app. Toward the end, we'll discuss various ways of packaging our applications so that they can be shared and installed on other machines without the user having to learn how to install and run Python programs.

Summary


In this chapter, we have learned a lot about some non-Tkinter technologies which can be used to supplement a GUI application.

We learned how to set up a very basic web service using the flask module. We know how to create URL routes using the app.route decorator and have learned how to handle both GET and POST requests. We also had an introduction to JSON as a portable way of sending information back to a client.

The SQLite database technology has been explored and we know how to create databases in our filesystem. We have practiced querying them and seen some basic SQL statement syntax. We have learned both how to put information into a database table and how to retrieve it again. We also saw that we can use the Row class to get information as a dictionary, which is often preferable to the standard tuple responses.

We have looked at sending GET and POST requests using the requests module. We have seen how to send data over to an endpoint, as well as parse the response with either r...
