-    On construit un nouveau widget \c AddressBook sur le tas en utilisant le mot-clé

+    On construit un nouveau widget \c AddressBook sur la pile et on invoque
+    sa méthode \l{QWidget::show()}{show()} pour l'afficher.
     Cependant, le widget ne sera pas visible tant que la boucle d'évènements
     n'aura pas été lancée. On démarre la boucle d'évènements en appelant la
     méthode \l{QApplication::}{exec()} de l'application; le résultat renvoyé
     par cette méthode est lui même utilisé comme valeur de retour pour la méthode
     \c main().
+    On comprend maintenant pourquoi \c AddressBook a été créé sur la pile: à la fin
+    du programme, l'objet sort du scope de la fonction \c main() et tous ses widgets enfants
+    sont supprimés, assurant ainsi qu'il n'y aura pas de fuites de mémoire.
