Variable non r�cup�r�e dans un Thread

Bonsoir,

Je dois dans mon projet, r�alis� un serveur dans une interface graphique QWidget.
Afin de rendre la fen�tre utilisable et ne pas freeze lorsque le serveur est en attente de connexion, je me suis tourn� vers les Thread.

Apr�s adaptation du code d'un camarade, j'en suis arriv� � ce code ci:

- Classe principale contenant le thread bluetooththread.h:

}

(le widget.h ne contient qu'un pointeur vers la classe BluetoothThread et le slot du QPushButton permettant la mise en route du serveur)

Le probl�me, c'est que la socket et les param�tres (en g�n�ral) que je donne au thread ne sont pas pris en compte comme le montre les deux valeurs diff�rentes lors de l'affichage du socket (au d�but du thread et apr�s sa cr�ation dans le start()).

Pourriez-vous m��claircir, merci ! :)
