Python GUI Programming - A Complete Reference Guide

By: Alan D. Moore, B. M. Harwani

Overview of this book

A responsive graphical user interface (GUI) helps you interact with your application, improves user experience, and enhances the efficiency of your applications. With Python, you’ll have access to elaborate GUI frameworks that you can use to build interactive GUIs that stand apart from the rest. This Learning Path begins by introducing you to Tkinter and PyQt, before guiding you through the application development process. As you expand your GUI by adding more widgets, you'll work with networks, databases, and graphical libraries that enhance its functionality. You'll also learn how to connect to external databases and network resources, test your code, and maximize performance using asynchronous programming. In later chapters, you'll understand how to use the cross-platform features of Tkinter and Qt5 to maintain compatibility across platforms. You’ll be able to mimic the platform-native look and feel, and build executables for deployment across popular computing platforms. By the end of this Learning Path, you'll have the skills and confidence to design and build high-end GUI applications that can solve real-world problems. This Learning Path includes content from the following Packt products: Python GUI Programming with Tkinter by Alan D. Moore Qt5 Python GUI Programming Cookbook by B. M. Harwani

Creating a custom menu bar

A big application is usually broken into small, independent, and manageable modules. These modules can be invoked either by making different toolbar buttons or menu items. That is, we can invoke a module on the click of a menu item. We have seen the File menu, the Edit menu, and so on in different packages, so let's learn to make a custom menu bar of our own.

In this recipe, we will learn to create a menu bar that shows certain menu items. We will learn to add menu items, add submenu items to a menu item, add separators between menu items, add shortcuts and tool tips to menu items, and much more. We will also learn to add actions to these menu items, so that when any menu item is clicked, a certain action will take place.

Our menu bar will consist of two menus, Draw and Edit. The Draw menu will consist of four menu items, Draw Circle, Draw Rectangle...
