Bonsoir,

Je poursuit la migration de mon application vers Qt 5.5 depuis Qt 4.7.

Je rencontre désormais des dizaines de fois lors de la compilation ce type d'erreur :



Dans le fichier discovery.cpp voici les lignes concernées :



Dans mon .pro j'ai bien ajouté : QT += widgets


J'ai fais d'autres "essais". Si par exemple je remplace par :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

#include <QtGlobal>
#if QT_VERSION >= 0x050000
#include <QObject>
#include <QtWidgets/QWidget>
#include <QtWidgets/QDialog>
#else
#include <QtGui>
#endif

J'obtiens alors d'autres erreurs :
