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.

Avoiding complexity

In this recipe, we will extend our Python GUI and learn ways to handle the ever-increasing complexity of our software development efforts.

Our co-workers and clients love the GUIs we create in Python and ask for more and more features to add to our GUI.

This increases complexity and can easily ruin our original nice design.

Getting ready

We will create a new Python GUI similar to those in the previous recipes and will add many features to it in the form of widgets.

How to do it…

We will start with a Python GUI that has two tabs and which looks as follows. Running results in the following:

The first new feature request we receive is to add functionality to Tab 1, which clears the scrolledtext widget.

Easy enough. We just add another button to Tab 1:

# Adding another Button 
self.action = ttk.Button(self.monty, text="Clear Text", command=self.clearScrol)    
self.action.grid(column=2, row=2)

We also have to create the callback method to add the desired functionality...
