Hallo zusammen.
ich habe folgendes Beispiel von Eclipse ausprobiert:
leider wirft es exakt diese Exception:
Die Kombination von AWT in SWT macht hier irgendwelche Probleme.
Mein Fenster wird zwar angezeigt, aber eine Exception gibts trotzdem.
Weiss jemand worans liegt, oder hatte schon mal ein ähnliches Problem?

Die Kombination von AWT in SWT macht hier irgendwelche Probleme.
Mein Fenster wird zwar angezeigt, aber eine Exception gibts trotzdem.
Weiss jemand worans liegt, oder hatte schon mal ein ähnliches Problem?
