Exemples

L’exemple de code suivant montre comment utiliser la ListView fonctionnalité de mosaïne. Dans l’exemple, l’affichage mosaïque affiche des éléments qui représentent des livres. Chaque élément est affiché sous forme de vignette contenant une icône d’un livre, le titre, l’auteur et l’année de publication. Pour que l’exemple de code fonctionne, vous devez inclure un fichier d’icône nommé Book.ico dans le même répertoire que l’exemple. Pour afficher l’affichage en mosaïque sans icônes, commentez les lignes relatives à l’objet ImageList .
