Comment accéder aux composants Swing depuis une autre class ?
Bonjour,
Pour mon projet, j'ai choisi de construire l'interface utilisateur (GUI) dans une classe séparée.
J'ai donc:
- Soft.java, le moteur de l'application, qui utilise les autres classes et lance les actions principales.
- SGui.java, l'interface utilisateur, contenant juste quelques actions sur les boutons.
Comment accéder aux composants Swing dans SGui depuis Soft ?
Voir les lignes 33, 34 de Soft.java (les 2 lignes commentées //)
Merci
