Bonjour à tous

Je suis actuellement entrain de réaliser une synchronisation de fichier sous java avec Netbeans.
Mais j'ai un souci, qui je pense ne dois pas être méchant.

Je m'explique j'ai utilsé Netbeans avec des interfaces java toutes prête, Mais je ne sais pas ajouter de composant manuellement dans le code je n'arrive que grâce à la palette netbeans. Si quelqu'un pourrait me dire comment afficher un Jpanel dans à partir de mon code sous netbeans se serait cool.

Je poste le code de l'interface ou je souhaite ajouter mon panneau:

Code : Sélectionner tout - Visualiser dans une fenêtre à part
