Lier un String entre 2 classes

**scorbo** · 28/05/2008, 11h44

Comment ça ? Tu veux envoyer une commande au 2ème PC pour qu'il t'envoie des données lorsque tu cliques sur le bouton 3 ? Ou tu veux afficher les données qu'un autre PC t'as envoyé lorsque tu cliques sur le bouton 3 ?

Si c'est la 2ème solution, il te suffit d'écrire une méthode dans ta classe PortComManager pour récupérer les données reçues :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

public String getMaChaineRecue() {
    return _maChaineRecue;
}

_maChaineRecue est mise à jour à chaque fois que tu reçois un évènement DATA_AVAILABLE.
