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.

Adding structure with container widgets

In Chapter 3, Window, Canvas, and Drawing, we learned how a Container is used to group multiple objects within a canvas. Using the layouts we explored in Chapter 4, Layout and File Handling, it is possible to automatically arrange each CanvasObject according to certain rules. However, sometimes, an application would like items to appear and disappear according to user interaction, or to have visual attributes beyond their size and position. Container widgets can provide these richer behaviors. These structural widgets can be found in the container package and include scrolling, grouping, and variations of hiding and showing content. Let’s explore each of these options (in alphabetical order).

AppTabs

The AppTabs container is used for controlling large areas of an application where the content should be switched out based on the current activity. For example, this may be used to fit lots of graphical elements into a small application...
