The class contains this:
Q_PROPERTY(QList<double> switch1 READ switch1 WRITE setSwitch1 NOTIFY switch1Changed)
void setSwitch2(QList<double> arg)
{
if (m_switch2 != arg)
{
m_switch2 = arg;
emit switch2Changed(arg);
}
}
The below works:
setSwitch2(QList<double>::fromVector(QVector<double>::fromStdVector(data->switch2)));
but now my datatype is QVariantList
instead of QList<double>
.
How should I replace QList with QVariant now?
This doesn't work:
setSwitch1(QVariantList::fromVector(QVector<QVariant>::fromStdVector(data->switch1)));
Just use this constructor:
QVariant::QVariant(const QList & val)
Constructs a new variant with a list value, val.
I.e. when storing a QList as a QVariant, the template type of the QList has to be a type that is OK for QVariant. There is no other constructor or conversion method for this.
You should be writing this:
QVariant variant(
QList<double>::fromVector(QVector<double>::fromStdVector(data->switch2))
);
setSwitchVariant(variant);
