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
MenuItem
s to take effect, you have to callsetContextMenu
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.

image
(NativeImage | String)
Creates a new tray icon associated with the image
