Hallo,
ich versuche gerade mit dem folgenden Code das JScrollPane "licenseScroll" scrollbar zu machen. In diesem wird der GNU Lizenz-Text eingfügt - ein langer Text, der eigentlich
ein automatisches Scrollen von JScrollPane auslösen sollte.
und das Weglassen beiden Policies hilft leider nichts. Die JScrollPane will einfach keine Scrollbalken anzeigen.
Sieht hier jemand, was ich vergessen habe oder falsch mache?
Besten Dank,
Wambui
