TextArea Größenänderung

[Popon]

Kann mir einer mal über meinen Code schauen und mir erklären warum meine TextArea bei manchen Abfragen die Größe automatisch verstellt und den Inhalt dadurch nicht anzeigt.

Ich habe in der Datenbank 10 Beschreibungen in der gleichen Tabelle.
6 von 10 Beschreibungen zeigt meine Textarea richtig an.
Bei den restlichen 4 ist die TextArea nur 2 Millimeter hoch, so dass der Inhalt nicht ersichtlich ist.

Hey ich habe deine Code mal Überarbeitet! und auch mal getestet soweit wie ich konnte! Ich habe mal ein wenig Refactor und so wie ich meine Code gestalten würde! Versuche mal das hier! habe nix in der Logik gemacht! nur den Code schöner gemacht und mit dem GridBagLayout rumgespielt oder dem GridBagConstraints mal richtige zuweißungen gemacht! Schau einfach mal hier:

@edit. schau dir mal das Buch an! Refactoring

 

[Popon]

Komischerweise funktioniert es ohne das ich was verändert habe...

Danke das Du mein Code refactorisiert hast....

Gruß Popon

 

[dayaftereh]

Also ich habe schon was am GridBagLayout gemacht! Super aber das es Klapt!

 

[Popon]

Trotzdem danke das Du Dir die Mühe gemacht hast...
