Bind functions to events using Lang.

# Actions and signals

# Get started with GNOME

Gtk has a set of predefined events that you can use in your application.

Declare `HelloWorld` as a new `Lang` class. Gjs requires classes to have the Name property defined.

const HelloWorld = new Lang.Class({ Name: 'HelloWorld',

`_init` is called when a new instance is created. Create a `GtkApplication`, then connect `activate` to the existing Gtk event `_onActivate` and `startup` to `_onStartup`:

_init: function() { this.application = new Gtk.Application(); this.application.connect('activate', Lang.bind(this, this._onActivate)); this.application.connect('startup', Lang.bind(this, this._onStartup)); },

Show the window upon application activation:

_onActivate: function(){ this._window.show_all(); },
