Python GUI Programming Cookbook, Second Edition - Second Edition

By: Burkhard Meier

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

Using dialog widgets to copy files to your network


This recipe shows us how to copy files from your local hard drive to a network location.

We will do this by using one of Python's tkinter built-in dialogs which enables us to browse our hard drive. We can then select a file to be copied.

This recipe also shows us how to make Entry widgets read-only and to default Entry to a specified location, which speeds up the browsing of our hard drive.

Getting ready

We will extend Tab 2 of the GUI we were building in the previous recipe, Passing queues among different modules.

How to do it…

Add the following code to our GUI in the create_widgets() method towards the bottom where we created Tab Control 2. The parent of the new widget frame is tab2, which we created at the very beginning of the create_widgets() method. As long as you place the following code physically below the creation of tab2, it will work:
