[Solved] How to store QList<QSharedPointer<Phase>> in QSettings

[sharethl]

Object only has 2 int properties.
One way I tried is convert QList<> to QVariant, but got this error
QVariant::save: unable to save type 'QList<QSharedPointer<Phase>>' (type id: 1060).
I do have Registered the class and implemented QDataStream

Q_DECLARE_METATYPE( QSharedPointer<Phase>)
QDataStream & operator << (QDataStream &out, const QSharedPointer<Phase> &phase);
QDataStream & operator >> (QDataStream &in, QSharedPointer<Phase> &phase);

setting.setValue("Phase", QVariant::fromValue(QSharedPointer<Phase>(phase));

Second way should work, convert Phase properties to QStringList, and save this QStringList, later decode it back.

Any one know why first way doesn't work?

Thanks

You also need to register the type and its stream operators, as described in the docs:

qRegisterMetaType<QSharedPointer<Phase>>("Phase");
qRegisterMetaTypeStreamOperators<QSharedPointer<Phase>>("Phase");

@Chris-Kawa Thanks, That works!
