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 12. Concurrency, Networking, and Cloud Services

So far, we've been focusing on designing and building the graphical elements of applications. Most modern software isn't complete without a solid connection to internet services and networking features. Adding dependencies to remote services could affect the stability of an application if it isn't correctly managed. Concurrency is also a key part of managing an interaction with remote services; we'll need to add more advanced task handling to manage these various communication channels.

In this chapter, we'll explore the following topics:

  • Thread handling and managing the user interface
  • Including remote resources in your application
  • Connecting to cloud services and handling error cases
  • Maintaining user experience when the network disconnects

By the end of this chapter, you should be able to integrate remote resources and cloud services into your application. You'll also see how to maintain a responsive user interface despite this new functionality...
