Fondamentalement, j'ai plusieurs widgets que j'essaie de basculer entre ... et la valeur par défaut est un QTabWidget. Mis à part quelques modifications, les deux exemples (QStackedWidget et QTabsExapmle) sont simplement mélangés. Je ne peux pas faire fonctionner la partie "connect" (obtenir une erreur: pas de fonction correspondante pour l'appel à QTabsExample :: connect), et rien ne s'affiche à l'écran sauf si stackedWidget->addWidget(tabWidget) est le premier dans la liste (et même la vue dans le coin supérieur gauche).Qt - QStackedWidget et l'aide QTabsExample

Pourriez-vous réduire la quantité de code et fournir un exemple minimal? –
c'est un peu un exemple minimal ... mis à part la quantité d'onglets. Je vais éditer pour moins d'onglets. –
j'ai enlevé quelques choses, mais il y a encore 3 onglets. Je dirais que c'est plutôt standard ... J'ai juste combiné 2 exemples. –
