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.

Updating the rest of the application

Before our changes to the form can take effect, we need to update the remaining portions of our application for the new functionality. Our main menu needs some navigation items so that users can switch between the record list and the form, and controller methods need to be created or updated in Application to bring together our new model and view functionality.

Main menu changes

Since we're already in the file, let's start by updating our main menu view with some commands to switch between the record list and record form. We'll add a Go menu containing two more options to our menu that will allow switching between the record list and a blank record form.

Add the following lines between the Options and Help menus:

        go_menu = tk.Menu(self, tearoff=False)
        go_menu.add_command(label="Record List",
        go_menu.add_command(label="New Record",
