JTabbedPane und JPanels

May 28, 2006 by Michael

Stellt man Java Swing Componenten (z.B. JPanels) in JTabbedPanes (javax.swing.JTabbedPane) dar, so gibt die isVisible Methode des JPanels false zurück, falls die Komponente nicht auf dem Reiter im Vordergrund ist. Sinnvolles Verhalten.

Hingegen geben Komponenten auf diesem JPanel mit isVisible alle true zurück… Irgendwie unsinnig. Und nervenaufraubend, wenn sich auf einmal eine Anwendung gänzlich anders verhält, nur weil man ein Register unterteilt hat…. *grummel* Also lieber direkt getSelectedIndex() aus JTabbedPane nutzen und Nerven behalten 😉
