Qt QTableView méthode de l'héritage multiple

Question

J'ai créé une interface utilisateur dans Qt Designer et je veux maintenant afficher les données. Je veux utiliser l'approche de l'héritage multiple. Voici le code de l'interface utilisateur.

Dans la méthode multiple d'héritage il y a un fichier .h et ses correspondants .cpp.I veulent quelqu'un pour me guider sur l'endroit où établir une connexion à la base de données SQLite (si son dans le fichier .cpp ou. fichier h) et comment communiquer avec le fichier d'interface utilisateur que j'ai montré pour afficher les données de la base de données sur Qtableview.

Merci.

Answer 1

Vous instancier QSqlTableModel, l'associer à la vue à l'aide de setModel et initialiser les propriétés de table appropriées au modèle. Tout faire dans init.
