Wanneer ik de Graphics van een bestaand JPanel ophaal dan krijg ik altijd
een nullPointerException. Iemand enig idee hoe dat zou komen?
Mijn code ziet er zo uit:

JPanel paneel = new JPanel(null);
Graphics g = paneel.getGraphics();

Ik heb die graphics nodig om te kunnen tekenen op mijn panel. Of moet ik dat
op een andere manier doen?
