[Solved] Java GUI: ProgressBar

[Evangeli]

Καλησπέρα σε όλους.

 

Γνωρίζετε μήπως, πως μπορώ να κάνω την progressbar μου να δείχνει την... πρόοδο; Έχω βρει πολλά παραδείγματα, αλλά όλα ανοίγουν σε νέα παράθυρα ενώ εγώ θέλω η πρόοδος να εμφανίζεται στο ένα και μοναδικό frame που υπάρχει στον κώδικα που επισυνάπτεται (αντικείμενο jProgressBar1).

Ξέχασα το συνημμένο....
