Python GUI Programming with Tkinter.

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.

Designing our menu 


Most applications organize functionality into a hierarchical menu system, typically displayed at the top of the application or screen (depending on the OS). While the organization of this menu varies between operating systems, certain items are fairly common across platforms. 

Of these common items, our application will need the following:

  • A file menu containing file operations such as open/save/export, and often an option to quit the application. Our users will need this menu to select a file and quit the program.
  • An options, preferences, or settings menu where users can configure the application. We'll need this menu for our toggle settings; we'll call it options for now.
  • A help menu, which contains links to help documentation, or, at the very least, an about message giving the basic information about the application. We'll implement this menu for the about dialog.
