JTabbedPane Taille automatique
Bonjour, je voudrais adapter la taille de deux sous panels à celui d'un panel principal.
Le panel principal s'appel panTabs et les sous panels HDMT et NEMO (sont de même structure).
Cependant quand je set la taille du panel principale puis crée une méthodes getTabsSize() pour récupérer le get il me met un nullpointer.
Classe qui créer le panel principale auquel on ajoute les sous panel :
