Salut à tous,

Je crée une application structurée de la façon suivante :
un JSplitPane Horizontal dans le quel, a gauche le tree et à droite un panel avec jtable
Les problèmes :
► JTree : il me met un jTree par défaut, comme si que je faisais une instance de trop et qui annule le miens
► JTable/JPanel : il me met que le dernier panel, et la jtable à que les entêtes avec trois lignes vides

Voici la classe MyJTree :
