## 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.
|
|
|
|
|
|
