[golang][gui]Hands On GUI Application Development in Go【在Go中动手进行GUI应用程序开发】

emmm 谷歌并没有给GOlang添加GUI武器库，让其大战群雄。

但是民间不缺乏大神。

这是golang基于GTK进行开发GUI的一个示例https://github.com/landv/golang-test/tree/master/gtk-examples

来进入正题，此书的读书笔记，国内暂未找到纸质版售卖的，从外边找了一份电子版的先看着。美刀买的贵，还是韩元便宜。哈哈哈。

Preface

Since the 1.0 release of the Go programming language in 2012, developers have enjoyed the increased productivity brought by the easy-to-read, quick-to-learn, cross-platform design of Go. Web apps and system utilities around the world are being built with Go to rapidly deliver reliable performance. Learning the language is easy, due to its centralized documentation and great programming environment support. Creating Graphical User Interfaces (GUIs) with Go, however, is still very new and there is not yet a standardized UI toolkit.
This definitive guide to programming GUIs with Go explores the most popular GUI packages available. It compares the vision behind each toolkit to help you pick the right approach for your project. Each toolkit is described in detail, outlining how to build beautiful, performant applications that users will love. Code samples and screenshots will aid any level of Go developer to create applications using these emerging technologies.

前言

自2012年Go编程语言1.0发布以来，开发人员享受到了Go易于阅读、快速学习、跨平台设计带来的生产力提高。世界各地的web应用程序和系统实用程序正在与go一起构建，以快速提供可靠的性能。由于集中的文档和强大的编程环境支持，学习这种语言很容易。然而，使用go创建图形用户界面（gui）仍然是非常新的，而且还没有一个标准化的ui工具包。

这是一个关于用go编程gui的权威指南，探讨了最流行的gui包。它比较了每个工具包背后的愿景，以帮助您为项目选择正确的方法。每个工具包都有详细的描述，概述了如何构建用户会喜欢的漂亮的、性能良好的应用程序。代码示例和屏幕截图将帮助任何级别的go开发人员使用这些新兴技术创建应用程序。

部分进行翻译哈，翻译不准确之处请见谅，还望通过本文的了解进去购买原版书籍。

Who this book is for

This book is written for Go developers who are interested in building native graphical applications for desktop computers and beyond. Some knowledge of building Go applications (command line based or web apps) is assumed, but not essential. The first section of this book looks at the history of the GUI, its importance to the evolution of modern personal computers, and how it can pose additional challenges to software developers.
Developers of GUI applications that are interested in trying Go may also find this book useful. Section 2, Toolkits Using Existing Widgets and Section 3, Modern Graphical Toolkits, explore the various frameworks available to the Go language and demonstrate how applications can be rapidly developed from basic principles.
Additionally, an experienced Go developer may find the final section useful. The chapters of section 4, Growing and Distributing Your Application covers how to design and build complex graphical interfaces that fit user expectations. It looks at the different approaches possible to support multiple operating system standards and how to integrate the GUI well with network resources and cloud services. The final chapters cover best practices in GUI applications with Go, and look at how to package and distribute your software through the various distribution channels available.

To get the most out of this book

A basic knowledge of the Go language is assumed throughout this book. If you are not yet familiar with its basic concepts, consider running through the online tutorial before you begin reading (tour.golang.org).

To benefit the most from later chapters, it would be ideal if you have in mind a particular application you are working on or would like to build. Applying the frameworks and tools used in this book to a particular project will aid your understanding of the various concepts. Additionally, this will deliver the benefit of you completing your project and preparing it for distribution.

充分利用这本书

 本书假定读者对Go语言都有基本的了解。如果您还不熟悉它的基本概念，请在开始阅读（tour.golang.org）之前，先仔细阅读在线教程。

为了从后面的章节中获得最大收益，如果您考虑到正在处理或想要构建的特定应用程序，则将是理想的选择。将本书中使用的框架和工具应用于特定项目将有助于您理解各种概念。此外，这将带来您完成项目并准备分发的好处。

Section 1: Graphical User Interface Development

For many years, graphical user interfaces (GUIs) have been the standard way for the average computer user to engage with a software product. They provide an intuitive user experience for potentially complex workflows within the familiar context of a desktop environment. Having evolved over more than 40 years, the traditional graphical application is being challenged by the ubiquity of web-based software and the emergence of mobile applications on modern smartphones and handheld computers. Despite these new trends, there are still many reasons why building a native graphical application for desktop (and laptop) computers could be the right strategy for your product.
In this introductory section, we will look at the history of the desktop GUI and how it has developed alongside technological innovation. We will discuss why, despite new alternative approaches, native graphical applications are still a great way to provide an intuitive user experience and a reliable software product. Building anything of quality takes effort, and software is no exception. We will explore the challenges that teams are likely to face when designing and building a native graphical application that aims to support multiple operating systems. Having reviewed the importance of the GUI and the challenges it can pose, we examine the Go programming language and demonstrate that its design fits very well with the creation of modern native graphical applications for multiple platforms.

The following chapters will be covered in this section:
• Chapter 1, The Benefits of Native Graphical Applications
• Chapter 2, Graphical User Interface Challenges
• Chapter 3, Go to the Rescue!
