const Gio = imports.gi.Gio; const GLib = imports.gi.GLib; const Gtk = imports.gi.Gtk;

class LabelExample {

/* Create the application itself This boilerplate code is needed to build any GTK+ application. */ constructor() { this.application = new Gtk.Application ({ application_id: 'org.example.jslabel', flags: Gio.ApplicationFlags.FLAGS_NONE });

// Connect 'activate' and 'startup' signals to the callback functions this.application.connect('activate', this._onActivate.bind(this)); this.application.connect('startup', this._onStartup.bind(this)); }

// Callback function for 'activate' signal presents windows when active _onActivate() { this._window.present(); }

// Build the application's UI _buildUI() {

// Create the application window this._window = new Gtk.ApplicationWindow({ application: this.application, window_position: Gtk.WindowPosition.CENTER, title: "Welcome to GNOME", default_height: 100, default_width: 200 });

// Create the label this.label = new Gtk.Label({ label: "Hello GNOME!" }); this._window.add(this.label);

// Show the window and all child widgets this._window.show_all(); }

// Run the application let app = new LabelExample (); app.application.run (ARGV);
