## Class: Tray

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

Process: [Main](../glossary.md#main-process)

`Tray` is an [EventEmitter][event-emitter].

```javascript
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 call `setContextMenu` again. For example:

```javascript
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.
