# Grille

Un élément graphique bouton connecté à une barre de progression, à l'intérieur d'une grille qui gère l'agencement.

#!/usr/bin/gjs

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

const GridExample = new Lang.Class ({ Name: 'Grid Example',

/* Create the application itself This boilerplate code is needed to build any GTK+ application. */ _init: function () { this.application = new Gtk.Application ({ application_id: 'org.example.jsgrid', 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 initializes menus and 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: "Grid Example"});

// Create the grid this.Grid = new Gtk.Grid ();

// Create the widgets inside the grid this.progressBar = new Gtk.ProgressBar (); this.Button = new Gtk.Button ({ label: "Button" }); this.Button.connect ("clicked", Lang.bind(this, this._clickHandler));

// Assemble the grid this._window.add (this.Grid); this.Grid.attach (this.Button, 1, 1, 1, 1); this.Grid.attach_next_to (this.progressBar, this.Button, Gtk.PositionType.BOTTOM, 1, 1);

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

// Here's the function that says what happens when the button is clicked _clickHandler: function () { this.progressBar.pulse (); }

});

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