Building Cross-Platform GUI Applications with Fyne

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 learned how the Fyne Widget API is designed and looked at a list of standard widgets. We saw how containers and collection widgets can help us organize and manage user interface components. The dialog package was also explored to show how we can use it with our applications in order to implement standard components for common activities.

We also saw how themes are implemented within the toolkit and how they apply to all the widget components. This chapter demonstrated the light and dark variants of the standard theme and showed that applications can provide their own themes for a custom look and feel.

By building a task tracking application, we saw how many of the built-in widgets are used, how to lay them out in various containers, and how user interactions can be tracked to manage some in-memory data. In the next chapter, we will look at data binding and storage APIs, which can help us manage more complex data requirements.
