◆ virtualMetacall()

int Object::virtualMetacall ( Object * object,
QMetaObject::Call call,
int index,

staticprotected

This method is modeled after \l{QMetaObject::metacall}. It takes a JavaScript object and performs call on it, using index as identifier for the property/method/etc to be used and a as arguments. Like \l{QMetaObject::metacall} this method is overly generic in order to reduce the API surface. On a plain Object it does nothing and returns 0. Specific objects can override it and do some meaningful work. If the metacall succeeds they should return a non-0 value. Otherwise they should return 0.

Most prominently, \l QMetaObject::ReadProperty and \l QMetaObject::WriteProperty calls can be used to manipulate properties of QObjects and Q_GADGETs wrapped by QV4::QObjectWrapper, QV4::QQmlTypeWrapper and QV4::QQmlValueTypeWrapper. They can also be used to manipulate elements in QV4::Sequence.
