Java - Problème de Look'n'Feels
Bonjour,
Grâce à la page
http://www.developpez.net/forums/arc...p/t-51382.html
j'ai intégré 2 look'n'Feel dans mon appli :
"Tonic" et "Quaqua".
J'ai une petite fenêtre permettant de choisir les look'n'feel listés dans une combo.
J'ai un événement sur la combo qui applique le thème à la fenêtre dès sa sélection, et qui l'applique à l'interface principale si on sort de la fenêtre avec OK.
Cependant dès que je choisis l'un de ces deux thèmes (les "DefaultLookAndFeel" fournis avec la JDK ne posent aucun pb), j'obtiens des Exceptions de ce genre :

Ensuite à chaque fois que j'essaye de re-changer de thème l'affichage empire et les exceptions pleuvent.
Voici un bout de mon code :
D'abord la méthode qui récupère la liste des thèmes standards et les insère dans un ArrayList, et insère à la fin les deux thèmes additionnels :

Voilà, merci à vous si vous me sortez de ces bugs graphiques...!
Autre exemple d'Exception
