Python GUI Programming Cookbook, Second Edition - Second Edition

Overview of this book

Python is a multi-domain, interpreted programming language. It is a widely used general-purpose, high-level programming language. It is often used as a scripting language because of its forgiving syntax and compatibility with a wide variety of different eco-systems. Python GUI Programming Cookbook follows a task-based approach to help you create beautiful and very effective GUIs with the least amount of code necessary. This book will guide you through the very basics of creating a fully functional GUI in Python with only a few lines of code. Each and every recipe adds more widgets to the GUIs we are creating. While the cookbook recipes all stand on their own, there is a common theme running through all of them. As our GUIs keep expanding, using more and more widgets, we start to talk to networks, databases, and graphical libraries that greatly enhance our GUI’s functionality. This book is what you need to expand your knowledge on the subject of GUIs, and make sure you’re not missing out in the long run.

Creating menu bars


In this recipe, we will add a menu bar to our main window, add menus to the menu bar, and then add menu items to the menus.

Getting ready

We will start by learning the techniques of how to add a menu bar, several menus, and a few menu items to show the principle of how to do it. In the beginning, clicking on a menu item will have no effect. We will then add functionality to the menu items, for example, closing the main window when clicking the Exit menu item and displaying a Help | About dialog.

We will continue to extend the GUI we created in the previous recipe, Aligning the GUI widgets by embedding frames within frames.

How to do it…

First, we'll have to import the Menu class from tkinter. Add the following line of code to the top of the Python module, where the import statements live:

Next, we will create the menu bar. Add the following code towards the bottom of the module, just above where we create the main event loop:

GUI_menubar_tearoff.py

In line 119, we are calling...
