Qthread et instanciation de classe

Bonjour j'ai deux classes , un pour gérer les événement IHM (IHM_application)et un autre pour les surveiller des entrées à l'aide d'Qthread (GPIO_Thread)

j'aimerais récupérer l’état d'un appui bouton de mon IHM dans mon Qthread.
J'instancie ma classe IHM dans mon Qthread (ligne 818 du code) mais ça ne fonctionne pas


quelqu'un à une piste?

Code:

Bonjour,

L'instanciation de l'IHM dans le QThread ne peut pas marcher, puisque le QThread ne doit pas toucher au graphique!

Il y a plusieurs solutions possibles, en voici une:
1- on crée une variable dans la classe QThread qui représentera l'état du bouton de l'IHM
2- on crée une méthode dans la classe QThread dont l'exécution mettra à jour la valeur de la variable ci-dessus
3- l'appui sur le bouton de l'IHM appellera une méthode de l'IHM (qui devrait déjà exister pour d'autre raisons!) qui appellera la méthode du QThread pour mettre à jour la variable du QThread.

Pour savoir si c'est une méthode adaptée, il faudrait savoir sous quelle forme cette variable du QThread sera utilisée par le QThread (désolé, mais je ne lirai pas un code de 900 lignes...).

En ce qui me concerne, c'est comme ça que je traite souvent la demande par l'IHM d'arrêt d'un thread, quand son exécution se fait dans une boucle (genre "while self.encore:"), et dans ce cas, la méthode du thread "stop()" met la variable "self.encore" à False, ce qui stoppe la boucle suivante et termine le thread.

Il y a d'autres solutions, comme par exemple une variable globale partagée (mais protégée par un verrou pour éviter les accès simultanés) ou une communication par signaux.

Bonjour et merci pour votre réponse.
La variable à mettre à jour est de type booléen (elle est liée à l'appui d'Qpush bouton)

Ci dessous l'appel de la méthode pour mettre à jour ma variable dans l'IHM:
