tray

A Tray represents an icon in operating system's notification area, it is usually attached with a context menu.

var app = require('app');
var Menu = require('menu');
var Tray = require('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', clicked: true },
    { label: 'Item4', type: 'radio' },
  ]);
  appIcon.setToolTip('This is my application.');
  appIcon.setContextMenu(contextMenu);
});

Platform limitations:

• On OS X clicked event will be ignored if the tray icon has context menu.
• On Linux app indicator will be used if it is supported, otherwise GtkStatusIcon will be used instead.
• App indicator will only be showed when it has context menu.
• When app indicator is used on Linux, clicked event is ignored.

So if you want to keep exact same behaviors on all platforms, you should not rely on clicked event and always attach a context menu to the tray icon.
