Pour l'instant, les calculs ne sont pas importants mais plutot l'apparence. Le truc est je n'arrive pas avec BorderLayout et GridLayout à produire exactement la meme interface que celle de windows(il ya des problèmes de bordures et mes boutons sont un peu plus gros, certains textes ne s'affichent pas). Si vous lancez calc de windows et comparer avec la mienne vous comprendrez où est le problème. Je ne dois qu'utiliser les 2 types de layouts cités en haut (contraintes du devoir).

Merci pour toute contribution.

Bonne journée
