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.

How to create independent message boxes

In this recipe, we will create our tkinter message boxes as standalone top-level GUI windows.

You will first notice that, by doing so, we end up with an extra window, so we will explore ways to hide this window.

In the previous recipe, we invoked tkinter message boxes via our Help | About menu from our main GUI form.

So, why would we wish to create an independent message box?

One reason is that we might customize our message boxes and reuse them in several of our GUIs. Instead of having to copy and paste the same code into every Python GUI we design, we can factor it out of our main GUI code. This can create a small reusable component which we can then import into different Python GUIs.

Getting ready

We have already created the title of a message box in the previous recipe, Creating message boxes - information, warning, and error. We will not reuse the code from the previous recipe but build a new GUI using very few lines of Python code.
