# GMenu

En GtkApplication med en enkel GMenu och SimpleActions

#!/usr/bin/gjs

imports.gi.versions.Gtk = '3.0';

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

class Application {

//create the application constructor() { this.application = new Gtk.Application ({ application_id: 'org.example.myapp', flags: Gio.ApplicationFlags.FLAGS_NONE });

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

//create the UI (in this case it's just the ApplicationWindow _buildUI() { this._window = new Gtk.ApplicationWindow ({ application: this.application, window_position: Gtk.WindowPosition.CENTER, title: "Welcome to GNOME" });

//uncommenting the line below will change the window size //this._window.set_default_size(600, 400);

//show the window and all child widgets (none in this case) this._window.show_all(); }

_showNew() { print("This doesn't do anything. It is only a demonstration."); }

_showAbout() { print("No AboutDialog here. This is only a demonstration."); }

//create the menu items and connect the signals to the callback functions. _initMenus() { let menu = new Gio.Menu(); menu.append("New",'app.new'); menu.append("About", 'app.about'); menu.append("Quit",'app.quit'); this.application.set_app_menu(menu);

let newAction = new Gio.SimpleAction ({ name: 'new' }); newAction.connect('activate', () => { this._showNew(); }); this.application.add_action(newAction);

let aboutAction = new Gio.SimpleAction ({ name: 'about' }); aboutAction.connect('activate', () => { this._showAbout(); }); this.application.add_action(aboutAction);

let quitAction = new Gio.SimpleAction ({ name: 'quit' }); quitAction.connect('activate', () => { this._window.destroy(); }); this.application.add_action(quitAction); }

//callback function for 'activate' signal _onActivate() { this._window.present(); }

//callback function for 'startup' signal _onStartup() { //You must call _initMenus() before calling _buildUI(). this._initMenus(); this._buildUI(); } };

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

I detta exempel använde vi följande:
