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 reusable GUI components

We will create reusable GUI components using Python. In this recipe, we will keep it simple by moving our ToolTip class into its own module. Then, we will import and use it for displaying tooltips over several widgets of our GUI.

Getting ready

We are building our code from Chapter 3, Look and Feel

How to do it…

We will start by breaking out our ToolTip class into a separate Python module. We will slightly enhance it to pass in the control widget and the tooltip text that we wish to display when we hover the mouse over the control.

We create a new Python module and place the ToolTip class code into it and then import this module into our primary module.

We then reuse the imported ToolTip class by creating several tooltips, which can be seen when hovering the mouse over several of our GUI widgets.

Refactoring our common ToolTip class code out into its own module helps us reuse this code from other modules. Instead of copy/paste/modify...
