ftyne

Fyne is a cross-platform GUI toolkit written in the Go programming language. It allows developers to build applications with a consistent look and feel across various operating systems, including Windows, macOS, Linux, iOS, and Android. Fyne is designed to be simple and efficient, making it suitable for both rapid prototyping and production applications.

The toolkit provides a set of pre-built UI widgets such as buttons, labels, entry fields, and sliders, which can be arranged and customized using a layout system. Fyne's declarative API enables developers to define user interfaces in a straightforward manner. It also supports custom widgets, allowing for more specialized user interface elements.

A key feature of Fyne is its focus on theming, which enables users to customize the appearance of applications. It comes with a default theme but allows for the creation and application of custom themes to alter colors, fonts, and widget styles. Fyne applications are compiled into native executables, eliminating the need for runtime dependencies beyond the Go standard library. This simplifies deployment and ensures a native performance experience. The project is open-source and actively developed, with a community contributing to its growth and improvement.
