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.

Preface

OpenGL animation


In the previous recipes, we used the wxPython and PyGLet frameworks to display OpenGL. In this recipe, we will use pure Python and OpenGL to create a red rectangle that bounces within a window that has a blue background.

Note

The examples in this recipe have been translated from the C programming language into Python using the OpenGL SuperBible Fourth Edition as a guide. While the Fourth Edition was published in the year 2007, the OpenGL examples still work and we can use them with Python.

Getting ready

This recipe requires the PyOpenGL package. The first recipe of this chapter,  PyOpenGL transforms our GUI, explains how to install this package.

How to do it…

First, we import several packages from OpenGL.  In the main() Python function, we initialize the GL Utility (glut) library. Then we choose a single buffer (as opposed to double buffering) and also select the Red, Green, Blue, Alpha (RGBA) color mode.

We then create a window via GLUT. No need for tkinter, wxPython or PyGLet...
