Fyne is an easy to use UI toolkit and app API written in Go. We use OpenGL (through the go-gl and go-glfw projects) to provide cross platform graphics.

Version 1.0.1 is the current release which was a bugfix and stability releae. We are now working towards 1.1 which will add new functionality.

To run a showcase of the features of Fyne execute the following:

cd $GOPATH/src/fyne.io/fyne/cmd/fyne_demo/
go build
./fyne_demo

And you should see something like this (after you click a few buttons):

Or if you are using the light theme:

Fyne is designed to be really easy to code with. Here are the steps to your first app.

As Fyne uses CGo you will require a C compiler (typically gcc). If you don't have one set up the instructions at Compiling may help.

By default Fyne uses the gl golang bindings which means you need a working OpenGL configuration. Debian/Ubuntu based systems may also need to install the libgl1-mesa-dev and xorg-dev packages.

Using the standard go tools you can install Fyne's core library using:

go get fyne.io/fyne

And then you're ready to write your first app!

package main

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

func main() {
	app := app.New()

	w := app.NewWindow("Hello")
	w.SetContent(widget.NewVBox(
		widget.NewLabel("Hello Fyne!"),
		widget.NewButton("Quit", func() {
			app.Quit()
		}),
	))

	w.ShowAndRun()
}

And you can run that simply as:

go run main.go

It should look like this:

Note that Windows applications load from a command prompt by default, which means if you click an icon you may see a command window. To fix this add the parameters -ldflags -H=windowsgui to your run or build commands.
