Bonjour,

J'ai besoin de créer un composant contenant plusieurs composants.

Je le fais à partir de l'exemple : http://www.codeguru.com/java/articles/128.shtml qui fonction pour un JFrame.

J'ai donc changer l'heritage JFrame en Jcomponent et modifié quelques trucs.

Est ce la bonne demarche ?
Cela ne fonctionne pas, il me manque la partie scrollable.

Code :

Sélectionner tout - Visualiser dans une fenêtre à part
