Python GUI programming with Tkinter

By: Alan D. Moore

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.

Chapter 5. Planning for the Expansion of Our Application

The application is a real hit! After some initial testing and orientation, the data entry staff have been utilizing your new form for a few weeks now. The reduction in errors and data entry time is dramatic, and there's a lot of excited talk about what other problems this program might solve. With even the director joining in on the brainstorming, you have a strong suspicion that you'll be asked to add some new features soon.

There's a problem, though; the application is already a script of several hundred lines, and you're worried about its manageability as it grows. You need to take some time to organize your codebase in preparation for future expansion.

In this chapter, we'll learn about the following topics:

  • How to separate the concerns of your application using the Model-View-Controller pattern
  • How to organize your code into a Python package
  • To create the basic files and directories for your package structure
  • How to use the Git version...
