redimensionner JFrame automatiquement avec un Composite Java

Je suis en œuvre des changements à une partie de démineur. L'une de ces choses est la difficulté. J'ai réussi à le faire et son travail, mais que le jeu conseil d'administration (dans sa propre Composite) est plus grand & les plus petites (selon la difficulté), je ne peux pas obtenir la JFrame pour redimensionner automatiquement. Je suis à l'aide de:

setPreferredSize(new Dimension(WIDTH, HEIGHT));

pour définir la taille initiale de la fenêtre, mais cela le rend VRAIMENT minuscule, en indiquant uniquement le mot "Fichier" de la JMenuBar. Je dois la redimensionner manuellement.

J'ai essayé setSize() et des choses comme cadre.pack() sur l'ActionListener événement, mais je n'arrive pas à l'obtenir à redimensionner.

Des conseils sur ce code, les méthodes à utiliser.
