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

Changing the icon of the main root window


One way to customize our GUI is to give it an icon different from the default icon that ships out of the box with tkinter. Here is how we do this.

Getting ready

We are improving our GUI from the recipe, Creating tabbed widgets, in Chapter 2, Layout Management. We will use an icon that ships with Python but you can use any icon you find useful. Make sure you have the full path to where the icon lives in your code, or you might get errors.

How to do it…

For this example, I have copied the icon from where I installed Python 3.6 to the same folder where the code lives.

Place the following code somewhere above the main event loop: 

    # Change the main windows icon 
    win.iconbitmap('pyc.ico')

Note how the feather default icon in the top-left corner of the GUI changed:

GUI_icon.py

How it works…

This is another property that ships with tkinter, which ships with Python 3.6 and above. We use the iconbitmap property to change the icon of our main root window form...
