Fyne: A Cross-Platform GUI Toolkit in Go Inspired by Material Design

Introduction

Fyne is an easy-to-use UI toolkit and application API written in Go. It is designed to build applications that run on desktop and mobile devices with a single codebase, inspired by Material Design. This powerful toolkit simplifies GUI development, allowing developers to create elegant and performant applications across various platforms including Android, iOS, Windows, macOS, and Linux.

Installation

To get started with Fyne, you will need Go version 1.17 or later, a C compiler, and your system's development tools. Once these prerequisites are met, you can install Fyne's core library using the standard Go tools:

go get fyne.io/fyne/v2@latest

After importing a new module, run the following command before compiling your code for the first time:

go mod tidy

You can also run a showcase of Fyne's features by installing and running the demo application:

go install fyne.io/fyne/v2/cmd/fyne_demo@latest
fyne_demo

Examples

Fyne is designed for ease of coding. Here is a simple "Hello Fyne!" application:

package main

import (
	"fyne.io/fyne/v2/app"
	"fyne.io/fyne/v2/container"
	"fyne.io/fyne/v2/widget"
)

func main() {
	a := app.New()
	w := a.NewWindow("Hello")

	hello := widget.NewLabel("Hello Fyne!")
	w.SetContent(container.NewVBox(
		hello,
		widget.NewButton("Hi!", func() {
			hello.SetText("Welcome :)")
		}),
	))

	w.ShowAndRun()
}

You can run this application with:

go run main.go
