Unable to write properties of Q_GADGET

beecksche

Hi,
i've defined a QObject derived class and a Q_GADGET struct in C++ to use in QML:

struct TypeName {
   Q_GADGET
   Q_PROPERTY(QString name MEMBER name)
   QString name;
}

Q_DECLARE_METATYPE(TypeName)

class MyClass : public QObject {
   Q_OBJECT
   Q_PROPERTY(TypeName type READ type)
public:
   MyClass() { qRegisterMetaType<TypeName>(); }
   Q_INVOKALBLE Type typeInvoked() const { return m_type; }
   TypeName type() const { return m_type; }
private:
   TypeName m_type;
}

If I call the property MyClass.type I'm not able to write the properties of TypeName. But if it is called by the invokable function I can:

MyClass {
   id: myClass
}

var typeProperty= myClass.type
typeProperty.name = "MyName"

var typeInvoked = myClass.typeInvoked()
typeInvoked.name = "MyName"

console.log(typeProperty.name) // '' <- ?
console.log(typeInvoked.name) // 'MyName'
