# Tray
|
|
|
|
A `Tray` represents an icon in an operating system's notification area, it is
|
|
usually attached with a context menu.
|
|
|
|
```javascript
|
|
const electron = require('electron');
|
|
const app = electron.app;
|
|
const Menu = electron.Menu;
|
|
const Tray = electron.Tray;
|
|
|
|
var appIcon = null;
|
|
app.on('ready', function(){
|
|
appIcon = new Tray('/path/to/my/icon');
|
|
var contextMenu = Menu.buildFromTemplate([
|
|
{ label: 'Item1', type: 'radio' },
|
|
{ label: 'Item2', type: 'radio' },
|
|
{ label: 'Item3', type: 'radio', checked: true },
|
|
{ label: 'Item4', type: 'radio' }
|
|
]);
|
|
appIcon.setToolTip('This is my application.');
|
|
appIcon.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.
|
|
|
|
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.
|
|
|
