Swing JScroolBar richtig benutzen

[TheSorm]

Ich habe einen kleinen Lvl editor Programiert, da das Lvl aber sehr breit ist muss man es eig mit scrool bar verschieben können um das ganze lvl bearbeiten zu können. Ich würde gerne wissen wie ich das am besten amche, alles was bis jetzt mit der JScroolBar und dem AdjustmentListener gemacht wurde kann, ist es warscheinlich auch, falsch sein! Nach fehlenden infos bitte Fragen 🙂
