Package systray is a cross platfrom Go library to place an icon and menu in the notification area. Tested on Windows XP,7,10 and Linux Mint 18.3.

Usage

func main() {
	// Should be called at the very beginning of main().
	systray.Run(onReady, onExit)
}

func onReady() {
	systray.SetIcon(icon.Data)
	systray.SetTitle("Awesome App")
	systray.SetTooltip("Pretty awesome超级棒")
	mQuit := systray.AddMenuItem("Quit", "Quit the whole app", systray.ItemDefault)
}

func onExit() {
	// clean up here
}

Menu item can be checked and / or disabled. Methods except Run() can be invoked from any goroutine. See demo code under example folder.

Platform specific concerns

Linux

sudo apt-get install libgtk-3-dev libappindicator3-dev

Checked menu item not implemented on Linux yet.

Warning: GtkStatusIcon has been deprecated in GTK 3.14!

Prepare icons

You can use filetobyte utility at cmd folder. Two ways:

  1. Do
go get github.com/amkulikov/systray/cmd/filetobytes

and after that use compiled binary directly, or use code generation in your project

//go:generate filetobytes -package=tray -dest=tray/data.go path/to/iconfile/or/iconsfolder
  1. Use go run to execute util.
//go:generate go run github.com/amkulikov/systray/cmd/filetobytes/main.go -package=tray -dest=tray/data.go example/icon

It will generate file data.go in tray folder that will contain

var filesByteData = map[string][]byte{...}

where key is a path to sourcefile and value is a binary representation of resource.
