Problème de panel

**flames** · 30/03/2007, 15h15

Bonjour à tous,

j'utilise le nouveau netbeans pour développer mon interface graphique cependant j'ai un problème, je suis obligé de cliquer sur ma fenêtre pour voir apparaître mon nouveau jPanel, je pense que c'est un problème de dimension. Mais le nouveau netbeans me paraît un peu flou pour voir les dimensions.
Voici le code:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part
