Package systray is a cross platfrom MacOS Go library to place an icon and menu in the notification area. Tested on Windows 8, Ubuntu 14.10 and Debian 7.6. Mac OSX

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")

	mUrl := systray.AddMenuItem("Open Lantern.org", "my home")
	mUrl.SetIcon(getIcon("assets/hacker.ico"))

	mmmmm := mUrl.AddSubMenuItem("mmmmmmmUrl-Sub2", "mmmmmmUrl-Sub2")
	mmmmm.SetTitle("uuuuuuu")

	mUrlSub := mUrl.AddSubMenuItem("mUrl-Sub1", "mUrl-Sub1")
	mUrlSub.SetIcon(getIcon("assets/hacker.ico"))
	mUrl.AddSubMenuItem("mUrl-Sub3", "mUrl-Sub3")

	mUrilSubSub := mUrlSub.AddSubMenuItem("mUrl-Sub1-Sub1", "mUrl-Sub1-Sub1")
	/*          */ mUrlSub.AddSubMenuItem("mUrl-Sub1-Sub2", "mUrl-Sub1-Sub2")
	/*          */ mUrlSub.AddSubMenuItem("mUrl-Sub1-Sub3", "mUrl-Sub1-Sub3")
	/*          */ mUrlSub.AddSubMenuItem("mUrl-Sub1-Sub4", "mUrl-Sub1-Sub4")
	// Sets the icon of a menu item. Only available on Mac.
	mQuit.SetIcon(icon.Data)
}

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.

Try

Under example folder. Place tray icon under icon, and use make_icon.bat or make_icon.sh, whichever suit for your os, to convert the icon to byte array. Your icon should be .ico file under Windows, whereas .ico, .jpg and .png is supported on other platform.

go get
go run main.go

Building and the Console Window

By default, the binary created by go build will cause a console window to be opened on both Windows and macOS when run.

Windows

To prevent launching a console window when running on Windows, add these command-line build flags:

go build -ldflags -H=windowsgui

macOS

On macOS, you will need to create an application bundle to wrap the binary; simply folders with the following minimal structure and assets:

SystrayApp.app/
  Contents/
    Info.plist
    MacOS/
      go-executable
    Resources/
      SystrayApp.icns
