# Entry

This application greets you by name through a pop-up window.

#!/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 EntryExample {

// Create the application itself constructor() { this.application = new Gtk.Application({ application_id: 'org.example.jsentry', 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 builds the UI _onStartup() { 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, default_height: 100, default_width: 300, border_width: 10, title: "What is your name?"});

// Create the text entry box this.entry = new Gtk.Entry (); this._window.add(this.entry);

// Connect the text entry box to a function that responds to what you type in this.entry.connect("activate", this._hello.bind(this));

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

_hello() {

// Create a popup dialog to greet the person who types in their name this._greeter = new Gtk.MessageDialog ({ transient_for: this._window, modal: true, text: "Hello, " + this.entry.get_text() + "!", message_type: Gtk.MessageType.OTHER, buttons: Gtk.ButtonsType.OK, });

// Show the popup dialog this._greeter.show();

// Bind the OK button to the function that closes the popup this._greeter.connect ("response", this._okClicked.bind(this)); }

_okClicked() { this._greeter.destroy(); }

};

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

In this sample we used the following:

Gtk.Application

Gtk.ApplicationWindow

Gtk.Entry

Gtk.MessageDialog
