jScrollpane aktualisieren

[dhachim]

Hallo,

ich habe nun ne ganze weile im Forum gesucht, aber leider keine Lösung für mein Problem gefunden.

Ich habe ein jContentpane, das in einem Frame ist. auf diesem Jcontentpane liegt ein jScrollpane.
dort adde ich ein Panel mit
jScrollPane.setViewportView(getJPanel());

nun habe ich auf diesem Panel ein Button, der das panel aktualisieren soll. ich denke mir remove(), und dann wieder add() sollte mir helfen, aber leider tut es das nicht.
repaint() funktioniert ja nur bei AWT Komponenten.

anbei mein CODE, hoffe jemand kann mir helfen.
Bei Zeile 193 versuche ich mein glück :-(

[The_S]

schonmal ein validate() versucht?

 

[dhachim]

versucht ja nur kam ich zu keinem ergebnis... ich weiss noch nicht mal wie ich an mein jPanel rankomme.
ich adde ja das panel mit setViewportView(getJPanel());

jScrollPane.remove(jScrollPane.getComponent(0));
jScrollPane.validate();

 

[Bleiglanz]

revalidate()

 

[dhachim]

ich weiss nicht wrum es nicht geht oder wie man es macht, aber ein einfacher
this.setSize(950,this.getHeight());
des frames hat mir geholfen....
