Overview of this book

Tkinter is widely used to build GUIs in Python due to its simplicity. In this book, you’ll discover Tkinter’s strengths and overcome its challenges as you learn to develop fully featured GUI applications. Python GUI Programming with Tkinter, Second Edition, will not only provide you with a working knowledge of the Tkinter GUI library, but also a valuable set of skills that will enable you to plan, implement, and maintain larger applications. You’ll build a full-blown data entry application from scratch, learning how to grow and improve your code in response to continually changing user and business needs. You’ll develop a practical understanding of tools and techniques used to manage this evolving codebase and go beyond the default Tkinter widget capabilities. You’ll implement version control and unit testing, separation of concerns through the MVC design pattern, and object-oriented programming to organize your code more cleanly. You’ll also gain experience with technologies often used in workplace applications, such as SQL databases, network services, and data visualization libraries. Finally, you’ll package your application for wider distribution and tackle the challenge of maintaining cross-platform compatibility.

Navigating Records with Treeview and Notebook

You've received another request for features in the application. Now that your users can open arbitrary files for appending, they'd like to be able to see what's in those files and correct old records using the data entry form they've grown accustomed to, rather than having to switch over to a spreadsheet. In a nutshell, it's finally time to implement read and update capabilities in our application.

In this chapter, we're going to cover the following topics:

  • In Implementing read and update in the model, we'll modify our CSV model for read and update capabilities.
  • In The Ttk Treeview, we'll explore the Ttk Treeview widget.
  • In Implementing a record list with Treeview, we'll use our knowledge of the Treeview widget to create an interactive display of records in the CSV file.
  • In Adding the record list to the application, we'll incorporate our new record list...
