# AboutDialog

Ένα παράθυρο αναγκαστικού διαλόγου που εμφανίζει πληροφορίες για μια εφαρμογή και τους δημιουργούς της. Αυτό εμφανίζεται με κλικ στο "Περί" στο μενού της εφαρμογής, που είναι κανονικά μια καλή θέση για να το βάλετε.

#!/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 AboutDialogExample {

// Create the application itself constructor() { this.application = new Gtk.Application({ application_id: 'org.example.jsaboutdialog', 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(); }

// Callback function for 'startup' signal creates the menu and builds the UI _onStartup() { this._initMenus(); this._buildUI(); }

// Build the application's UI _buildUI() { // Create the application window this._window = new Gtk.ApplicationWindow({ application: this.application, window_position: Gtk.WindowPosition.CENTER, title: "AboutDialog Example", default_height: 250, default_width: 350 });

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

// Create the application menu _initMenus() { let menu = new Gio.Menu(); menu.append("About", 'app.about'); menu.append("Quit",'app.quit'); this.application.set_app_menu(menu);

// Create the "About" menu option and have it call the _showAbout() function let aboutAction = new Gio.SimpleAction({ name: 'about' }); aboutAction.connect('activate', () => { this._showAbout(); }); this.application.add_action(aboutAction);

// Create the "Quit" menu option and have it close the window let quitAction = new Gio.SimpleAction ({ name: 'quit' }); quitAction.connect('activate', () => { this._window.destroy(); }); this.application.add_action(quitAction); }

_showAbout() {

// String arrays of the names of the people involved in the project var authors = ["GNOME Documentation Team"]; var documenters = ["GNOME Documentation Team"];

// Create the About dialog let aboutDialog = new Gtk.AboutDialog({ title: "AboutDialog Example", program_name: "GtkApplication Example", copyright: "Copyright \xa9 2012 GNOME Documentation Team", authors: authors, documenters: documenters, website: "http://developer.gnome.org", website_label: "GNOME Developer Website" });

// Attach the About dialog to the window aboutDialog.modal = true; aboutDialog.transient_for = this._window;

// Show the About dialog aboutDialog.show();

// Connect the Close button to the destroy signal for the dialog aboutDialog.connect('response', function() { aboutDialog.destroy(); }); } };

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