Flytte rundt på et JPanel
Heysa.
Jeg har oprettet et JPanel, som jeg bruger som baggrund. Inde i dette JPanel, skal jeg tilføje nogle andre JPanels, som hver i sær indeholdeholder noget data, et billede osv.
Disse "Under" JPanels, dem skal jeg kunne flytte rundt i det store JPanel, men det kan jeg ikke lige få til at virke.
SetLocation virker åbenbart ikke på et JPanel, selvom funktionen findes.
HJÆLP! :)

Da du lukkede spørgsmålet, besluttede jeg egentlig ikke at gøre mere ved sagen, men da jeg ikke holdt hvad jeg lovede, nemlig at vende tilbage
senere på dagen, så for du alligevel en løsning her.
Løsningen består af 2 classer, 'Stadion' og 'Field', kompiler først 'Field'
derefter 'Stadion', køres fra 'Stadion'
I bunden af classen 'Field' skal du indsætte stien til en spiller fra
hvert hold - spillerne kan flyttes med musen.
Sorry - det tog lidt tid!
