Solved Migrating Qt 4.8 to Qt 5.8, QtDeclarative

[SPlatten]

I'm porting a Qt 4.8 project to Qt 5.8, I've been using:

https://wiki.qt.io/Transition_from_Qt_4.x_to_Qt5

I am not getting:

C1083: Cannot open include file: 'QDeclarativeItem': No such file or directory
C2678: binary '+': no operator found which takes a left-hand operand of type 'QUuid' (or there is no acceptable conversion)

I don't believe the two are related, but any help is greatly appreciated.

@SPlatten I think it should be

inline QString id() const { return faultID().toString() + m_location; }
inline QUuid faultID() const { return m_faultID; }

@SPlatten As explained here: https://doc.qt.io/qt-5/qtquick-porting-qt5.html
replace QDeclarativeItem with QQuickItem.

Regarding second error: please post the code where it happens.

@jsulm , thank you.

The C2678 is in a file called activefaultitem.h on the line:

inline QString id() const { return faultID() + m_location; }  // <- This is the highlighted error
inline QUuid faultID() const { return m_faultID.toString(); }

QUuid m_faultID;
QString m_location;

@SPlatten said in Migrating Qt 4.8 to Qt 5.8, QtDeclarative:

faultID()

I guess this returns a QUuid?
Change it to

inline QString id() const { return faultID() + QUuid(m_location); }

[SPlatten]

The same error is reported on the same line. Is it actually because the return type is a QString an the faultID() does not return a QString?

@SPlatten I think it should be

inline QString id() const { return faultID().toString() + m_location; }
inline QUuid faultID() const { return m_faultID; }
