			Die im Bild dargestellte GUI verwendet eine {{JAPI\|JTabbedPane}}, deren Reiter versteckt sind. Der Wechsel auf eine andere Komponente in der JTabbedPane, also einen anderen Reiter, erfolgt mit Hilfe der [[JButton\|JButtons]].

			Bei dem Beispiel gibt es also große Ähnlichkeit mit einem [[CardLayout]].
