Liebe Kollegen,
Hat Jemand schonmal gleiches Problem mit meinem?
Ich schreibe ein Program in Modular Forme. Die sind alle 3 Dateien zusammen,
und zwar: gudangit.java ; jendelautama.java ; deitem.java .
Mein 'deitem' (JInternalFrame) zeigt leeren Formular. Es zeight gar keine was
ich schon mit GridBagLayout geschrieben habe.
Weiss Jemand welche mein Fehle ist?
Danke Vorher.

new jendelautama();
