Hands-On GUI Application Development in Go

By: Andrew Williams

Overview of this book

Go is often compared to C++ when it comes to low-level programming and implementations that require faster processing, such as Graphical User Interfaces (GUIs). In fact, many claim that Go is superior to C++ in terms of its concurrency and ease of use. Most graphical application toolkits, though, are still written using C or C++, and so they don't enjoy the benefits of using a modern programming language such as Go. This guide to programming GUIs with Go 1.11 explores the various toolkits available, including UI, Walk, Shiny, and Fyne. The book compares the vision behind each project to help you pick the right approach for your project. Each framework is described in detail, outlining how you can build performant applications that users will love. To aid you further in creating applications using these emerging technologies, you'll be able to easily refer to code samples and screenshots featured in the book. In addition to toolkit-specific discussions, you'll cover more complex topics, such as how to structure growing graphical applications, and how cross-platform applications can integrate with each desktop operating system to create a seamless user experience. By delving into techniques and best practices for organizing and scaling Go-based graphical applications, you'll also glimpse Go's impressive concurrency system. In the concluding chapters, you'll discover how to distribute to the main desktop marketplaces and distribution channels. By the end of this book, you'll be a confident GUI developer who can use the Go language to boost the performance of your applications.

Chapter 10. Fyne - Material Design-Based GUI

Fyne is a UI toolkit and application API designed to be easy to use. Its interface design follows the material design principles, providing cross-platform graphics that appear identical on all supported platforms. This chapter explores how to write graphical applications for multiple platforms with Fyne.

We'll cover the following topics:

  • The vision and design of the Fyne project
  • Building a simple Fyne-based application for multiple platforms
  • API design and the widgets provided by Fyne
  • How to create a complete application using Fyne

By the end of this chapter, you should have an understanding of Fyne project's ambitions and will have built multiple cross-platform graphical applications using the toolkit.
