Controller.dialog (Dialogfenster)1

DialogLauncher

Import

Das statische Attribut dialog() der Klasse Controller kann über einen statischen Import eingebunden werden:

import static pi.Controller.dialog();

Alle Dialog-Fenster drängen sich kompromisslos in den Vordergrund und die entsprechende Methode endet erst dann, wenn das Fenster wieder geschlossen wird.
