Class: Tray

Add icons and context menus to the system's notification area.

Process: Main

Tray is an EventEmitter.

const {app, Menu, Tray} = require('electron')

let tray = null
app.on('ready', () => {
  tray = new Tray('/path/to/my/icon')
  const contextMenu = Menu.buildFromTemplate([
    {label: 'Item1', type: 'radio'},
    {label: 'Item2', type: 'radio'},
    {label: 'Item3', type: 'radio', checked: true},
    {label: 'Item4', type: 'radio'}
  ])
  tray.setToolTip('This is my application.')
  tray.setContextMenu(contextMenu)
})

Platform limitations:

  • On Linux the app indicator will be used if it is supported, otherwise GtkStatusIcon will be used instead.
  • On Linux distributions that only have app indicator support, you have to install libappindicator1 to make the tray icon work.
  • App indicator will only be shown when it has a context menu.
  • When app indicator is used on Linux, the click event is ignored.
  • On Linux in order for changes made to individual MenuItems to take effect, you have to call setContextMenu again. For example:
const {app, Menu, Tray} = require('electron')

let appIcon = null
app.on('ready', () => {
  appIcon = new Tray('/path/to/my/icon')
  const contextMenu = Menu.buildFromTemplate([
    {label: 'Item1', type: 'radio'},
    {label: 'Item2', type: 'radio'}
  ])

  // Make a change to the context menu
  contextMenu.items[1].checked = false

  // Call this again for Linux because we modified the context menu
  appIcon.setContextMenu(contextMenu)
})
  • On Windows it is recommended to use ICO icons to get best visual effects.

If you want to keep exact same behaviors on all platforms, you should not rely on the click event and always attach a context menu to the tray icon.

new Tray(image)

Creates a new tray icon associated with the image.
