systray is a cross-platform Go library to place an icon and menu in the notification area. This repository is a fork of getlantern/systray removing the GTK dependency and support for legacy linux system tray.

• Supported on Windows, macOS, Linux and many BSD systems
• Menu items can be checked and/or disabled
• Methods may be called from any Goroutine

package main

import "fyne.io/systray"

func 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")

	// Sets the icon of a menu item. Only available on Mac and Windows.
	mQuit.SetIcon(icon.Data)
}

func onExit() {
	// clean up here
}

Most graphical toolkits will grab the main loop so the Run code above is not possible. For this reason there is another entry point RunWithExternalLoop. This function of the library returns a start and end function that should be called when the application has started and will end, to loop in appropriate features.

See full API as well as CHANGELOG.

Have go v1.12+ or higher installed? Here's an example to get started on macOS:

git clone https://github.com/fyne-io/systray
cd systray/example
env GO111MODULE=on go build
./example

On Windows, you should build like this:

env GO111MODULE=on go build -ldflags "-H=windowsgui"

The following text will then appear on the console:

go: finding github.com/fyne-io/systray latest

Now look for Awesome App in your menu bar!

This implementation uses DBus to communicate through the SystemNotifier/AppIndicator spec, older tray implementations may not load the icon.

• To avoid opening a console at application startup, use "fyne package" for your app or manually use these compile flags:

go build -ldflags -H=windowsgui

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

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

When running as an app bundle, you may want to add one or both of the following to your Info.plist:

<!-- avoid having a blurry icon and text -->
	<key>NSHighResolutionCapable</key>
	<string>True</string>

	<!-- avoid showing the app on the Dock -->
	<key>LSUIElement</key>
	<string>1</string>
