Bonsoir,
Comment pouvons-nous modifier la taille de botton dans le une panel, telle que le bouton est moins petit que la largeur de panel?
le code au dessous:
/**
* A JOutlookBar provides a component that is similar to a JTabbedPane, but instead of maintaining
* tabs, it uses Outlook-style bars to control the visible component
*/

Je ne comprends pas ta question et ton code est illisible, essaye d'être plus précis, choisis des parties de ton code à publier et utilise les balises (troisième bouton en partant de la droite)
