About this book

The history of graphical application development is long and complicated, with various development challenges that persist to this day. The mix of technologies involved and the need to use different programming languages led to a very steep learning curve for developers looking to build applications across multiple platforms.

In Building Cross-Platform GUI Applications with Fyne, you'll understand how the Go language, when paired with a modern graphical toolkit such as Fyne, can overcome these issues and make application development much easier. To provide an easy-to-use framework for cross-platform app development, the Fyne project offers many graphical concepts and design principles that are outlined throughout this book.

By working through five example projects, you'll learn how to build apps effectively, focusing on each of the main areas, including the canvas, layouts, file handling, widgets, data binding, and themes. The book will also show you how the completed applications can then be run on your desktop computer, laptop, and smartphone. After completing these projects, you will discover how to prepare applications for release and distribute them to platform marketplaces and app stores.

By the end of this book, you'll be able to create cross-platform graphical applications with visually appealing user interfaces and concise code.

Section 1: Why Fyne? The Reason for Being and a Vision of the Future

Since their invention nearly 50 years ago, graphical user interfaces (GUIs) have been the standard way to interact with a software product. In this time they have evolved, and traditional graphical applications are being challenged by the ubiquity of web-based software and new interaction methods for smartphones and handheld computers. Despite these new trends, there are still many reasons why building a native graphical application could be the right strategy for your product—especially if it could be deployed to all the platforms available.

In this section, we will see how GUIs and the graphical toolkits used to program them have evolved. We will explore the pros and cons of the technologies over the years and how some can be used for cross-platform development. We will learn about the Fyne project, its background and vision, and how it aims to be an ideal solution to the evolving needs of GUI development.

This section will cover the following topics:

  • Chapter 1, A Brief History of GUI Toolkits and Cross-Platform Development
  • Chapter 2, The Future According to Fyne

We start with a short review of the history of desktop computers and traditional GUIs.
