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

Using a spin box control


In this recipe, we will use a Spinbox widget, and we will also bind the Enter key on the keyboard to one of our widgets.

Getting ready

We will use our tabbed GUI and add a Spinbox widget above the ScrolledText control. This simply requires us to increment the ScrolledText row value by one and to insert our new Spinbox control in the row above the Entry widget.

How to do it...

First, we add the Spinbox control. Place the following code above the ScrolledText widget:

    # Adding a Spinbox widget 
    spin = Spinbox(mighty, from_=0, to=10) 
    spin.grid(column=0, row=2)

This will modify our GUI as follows:

GUI_spinbox.py

Next, we will reduce the size of the Spinbox widget:

    spin = Spinbox(mighty, from_=0, to=10, width=5)

Running the preceding code results in the following GUI:

GUI_spinbox_small.py

Next, we add another property to customize our widget further; bd is a short-hand notation for the borderwidth property:

spin = Spinbox(mighty, from_=0, to=10, width=5 , bd=8)

Running...
