Das GridLayout(3, 2) hat drei Zeilen und zwei Spalten. Drei mal zwei macht sechs. Wenn Du nur drei der versprochenen sechs Komponenten hinzufügst, kann das anders aussehen als Du glaubst. Wie soll es denn ausehen?

[SlaterB]

was genau ist denn dein Layout-Ziel?
nach einen Blick auf das Beispiel in
How to Use GridLayout (The Java™ Tutorials > Creating a GUI with JFC/Swing > Laying Out Components Within a Container)
scheint
new GridLayout(0,2);
besser zu sein, falls erst eine Zeile komplett gefüllt werden soll?

aber auch bei 3,2, werden bei ganzen 6 Komponenten erst die Zeilen aufgefüllt,
ist es wirklich wichtig, was passiert, wenn nur 3 Komponenten in ein Layout für 6 Zellen eingefügt werden?
