znam da treba nesto sa ovom komandom ali ne znam gdje u koju zagradu da ubacim.
Sada je trenutno kad se neki parametri ubace za x i y pokaze se pozicija u appletu samo sto je pozadina plava a ja hocu bilo koju drugu sliku da ubacim. Molio bih nekoga ko vec duze radi i zna kako da to uradim da mi ubaci na pravo mjesto. Ja sam pokusao sa ovim dole ali se nikakva promjena ne desava.
Hvala unaprijed
