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 8. Improving the Look with Styles and Themes

While programs can be perfectly functional with plain text in shades of black, white, and gray, the subtle use of colors, fonts, and images can enhance the visual appeal and usability of even the most utilitarian applications. Your data entry application is no exception. Your boss and your users have brought several issues to your attention, which seem to require the use of Tkinter's styling capabilities. Your boss has informed you that corporate HQ requires all in-house software to prominently display the company logo, while the data entry staff have mentioned a variety of issues with the readability and overall look of the application.

In this chapter, we're going to learn about some features of Tkinter that will help us to solve these issues:

  • We'll learn how to add images to our Tkinter GUI
  • We'll learn how to adjust the fonts and colors in our Tkinter widgets, both directly and with tags
  • We'll learn how to adjust the look of Ttk widgets...
