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

How widgets dynamically expand the GUI


You may have noticed in the previous screenshots and by running the code that the widgets have the capability of extending themselves to the space they need in order to visually display their text.

Note

  • Java introduced the concept of dynamic GUI layout management. In comparison, visual development IDEs, such as VS.NET, lay out the GUI in a visual manner, and basically hardcode the x and y coordinates of the UI elements.
  • Using tkinter, this dynamic capability creates both an advantage and a little bit of a challenge because sometimes our GUI dynamically expands when we would rather it not be so dynamic! Well, we are dynamic Python programmers, so we can figure out how to make the best use of this fantastic behavior!

Getting ready

In the beginning of the previous recipe, Using padding to add space around widgets, we added a LabelFrame widget. This moved some of our controls to the center of column 0. We might not want this modification in our GUI layout. Next...
