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.whenReady().then(() => {
  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.whenReady().then(() => {
  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, [guid])

• image (NativeImage | String)
• guid String (optional) Windows - Assigns a GUID to the tray icon. If the executable is signed and the signature contains an organization in the subject line then the GUID is permanently associated with that signature. OS level settings like the position of the tray icon in the system tray will persist even if the path to the executable changes. If the executable is not code-signed then the GUID is permanently associated with the path to the executable. Changing the path to the executable will break the creation of the tray icon and a new GUID must be used. However, it is highly recommended to use the GUID parameter only in conjunction with code-signed executable. If an App defines multiple tray icons then each icon must use a separate GUID.

Creates a new tray icon associated with the image.
