Hi guys
I want to use Qt Quick/C++ together. For this, I wrote SteelProfile Class (C++) and own functions. I can’t assign “steelprofileID.steelStandardName” value to ListElement. There is a weird situation. This code(on below) shows to me correct value, but I can’t assign to ListElement. I got ListElement: cannot use script for property value error.
console.log("Value: " + steelprofileID.steelStandardName)
There is the problem?
steelprofile.h
class SteelProfile : public QObject
{
Q_OBJECT
Q_PROPERTY(QString steelStandardName READ steelStandardName WRITE setSteelStandardName) //NOTIFY steelStandardNameChanged
public:
explicit SteelProfile(QObject *parent = 0);
signals:
public slots:
Q_INVOKABLE QString steelStandardName() const;
void setSteelStandardName(const QString &steelStandardName);
private:
QString sName;
};
steelprofile.cpp
SteelProfile::SteelProfile(QObject *parent) :
QObject(parent)
{
qDebug() << "SteelProfile()";
sName = "Europe";
}
QString SteelProfile::steelStandardName() const{
qDebug() << "steelStandardName()";
return sName;
}
void SteelProfile::setSteelStandardName(const QString &steelStandardName){
qDebug() << "setSteelStandardName()";
sName = steelStandardName;
}

}
ListElement{
steelStandardName: "US"

}

QObject *topLevel = engine.rootObjects().value(0);
