Python GUI Programming with Tkinter.

Overview of this book

Tkinter is a lightweight, portable, and easy-to-use graphical toolkit available in the Python Standard Library, widely used to build Python GUIs due to its simplicity and availability. This book teaches you to design and build graphical user interfaces that are functional, appealing, and user-friendly using the powerful combination of Python and Tkinter. After being introduced to Tkinter, you will be guided step-by-step through the application development process. Over the course of the book, your application will evolve from a simple data-entry form to a complex data management and visualization tool while maintaining a clean and robust design. In addition to building the GUI, you'll learn how to connect to external databases and network resources, test your code to avoid errors, and maximize performance using asynchronous programming. You'll make the most of Tkinter's cross-platform availability by learning how to maintain compatibility, mimic platform-native look and feel, and build executables for deployment across popular computing platforms. By the end of this book, you will have the skills and confidence to design and build powerful high-end GUI applications to solve real-world problems.

In this chapter, our simple form has taken a big step forward towards being a fully-blown application. We've implemented a main menu, option settings that are persisted between executions, and an About dialog. We've added the ability to select a file where records are saved, and improved the visibility of form errors with an error dialog. Along the way, you learned about Tkinter menus, file dialogs, and message boxes, as well as the various options for persisting data in the standard library.

In the next chapter, we're going to be asked to make the program read and write. We'll learn about Tkinter's tree widget, how to switch between main views, and how to make our CSVModel and DataRecordForm classes capable of reading and updating existing data.
