# Diálogo

Una ventana emergente personalizable, que contiene un área de contenido y un área de acción. Esta área de contenido del diálogo de ejemplo contiene un mensaje, y su área de acción contiene un botón que cierra el diálogo.

#!/usr/bin/gjs

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

const DialogExample = new Lang.Class ({ Name: 'Dialog Example',

// Create the application itself _init: function () { this.application = new Gtk.Application ({ application_id: 'org.example.jsdialog', flags: Gio.ApplicationFlags.FLAGS_NONE });

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

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

// Callback function for 'startup' signal builds the UI _onStartup: function () { this._buildUI (); },

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

// Create the application window this._window = new Gtk.ApplicationWindow ({ application: this.application, window_position: Gtk.WindowPosition.CENTER, title: "Gtk.Dialog Example", default_height: 50, default_width: 250 });

// Create a button this._button = new Gtk.Button ({label: "Click Me"}); this._window.add (this._button);

// Bind it to the function that creates the dialog this._button.connect ("clicked", Lang.bind(this, this._createDialog));

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

_createDialog: function () {

// Create the dialog this._dialog = new Gtk.Dialog ({ transient_for: this._window, modal: true, title: "A Gtk+ dialog" });

// Create the dialog's content area, which contains a message this._contentArea = this._dialog.get_content_area(); this._message = new Gtk.Label ({label: "This demonstrates a dialog with a label"}); this._contentArea.add (this._message);

// Create the dialog's action area, which contains a stock OK button this._actionArea = this._dialog.get_action_area(); this._OKButton = new Gtk.Button.new_from_stock (Gtk.STOCK_OK); this._actionArea.add (this._OKButton);

// Connect the button to the function that handles what it does this._OKButton.connect ("clicked", Lang.bind (this, this._OKHandler));

this._dialog.show_all(); },

_OKHandler: function (dialog, response_id) {

// Destroy the dialog this._dialog.destroy(); }

});

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

En este ejemplo se usa lo siguiente:

Gtk.Application

Gtk.ApplicationWindow

Gtk.Dialog
