Following are most commonly used techniques: QtCore.QObject.connect(widget, QtCore.SIGNAL(‘signalname’), slot_function) la réponse de Jacob est impressionnante. J'aimerais juste ajouter un exemple comparatif à la programmation intégrée. venant d'un arrière-plan RTOS/ISR intégré, il a été utile de voir les similitudes entre la connexion directe de Qt et le comportement préventif des ISRs et la connexion QueuedConnection de Qt aux Messages mis en file d'attente dans un RTOS entre les tâches.
