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.

Creating the ABQ database

Now that we've modeled our data and gotten a feel for the data types available, it's time to build our database. To begin, create a database on your SQL server called abq and make yourself the owner.

Next, under your project root folder, create a new directory called sql. Inside the sql folder, create a file called create_db.sql. We'll start writing our database creation code in this file.

Creating our tables

The order in which we create our tables is significant. Any table referred to in a foreign key relationship will need to exist before the relationship is defined. Because of this, it's best to start with your lookup tables and follow the chain of one-to-many relationships until all the tables are created. In our ERD, that takes us from roughly the upper-left to the lower-right.

Creating the lookup tables

We need to create the following three lookup tables:

  • labs: This lookup table will contain the ID strings for our laboratories.
  • lab_techs: This lookup table will have...
