Overview of 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.

Summary

In this chapter, we have seen how to deviate from the standard components and built-in theme in various ways. We explored how existing widgets can be extended and adapted, as well as how to build our own components from scratch. We also saw how custom themes can be created and how we can apply our own customizations to the default theme through theme extension.

With this knowledge, we created an application that was a mix of standard and custom components. We added some visual enhancements through our widget's renderer, but also created further customization by defining a custom theme. Through the code in this chapter, we learned how to customize individual elements and widgets, as well as how to make visual changes that apply across custom and standard widgets, using the theme API.

This brings us to the end of our exploration of the Fyne toolkit APIs and their functionality. In the following chapters, we will see how to create and manage GUI applications and how...
