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 8. Shiny - Experimental Go GUI API

Shiny is an experimental GUI library designed from scratch and written purely in Go. It was created to explore what's possible when building a cross-platform GUI for the Go language. It is not an official GUI toolkit for Go (though it was created by developers at Google) but provides a solid basis for graphical applications on most supported Go platforms.

This chapter explores how to use the Shiny project to build cross-platform graphical applications without the need for C libraries or pre-installed dependencies. The following topics will be covered in this chapter:

  • The design principles of the Shiny project and its widgets
  • How the toolkit is built to support multiple platforms without external drivers or native libraries
  • Building a basic graphical application that can easily cross-compile to different systems
  • Creating a a complete application using Shiny

At the end of this chapter, you should be well-versed in this experimental new API.
