Extracting multiple possible custom types from QDBusVariant

[Lurkki]

I have a method on DBus returning a variant, where the return value is one of multiple custom types.

QDBusInterface server("org.customtest", "/", "org.customtest");

QDBusReply<QDBusVariant> reply = server.call("person");
if (reply.isValid()) {
    auto arg = reply.value().variant().value<QDBusArgument>();
    Person p;
    arg >> p;
    qDebug() << p.name << p.age;
}

Now this code obviously doesn't work, when the return type isn't Person, so is there any way to identify the type of this variant?

Hi,

Out of curiosity, why would a call to the person endpoint return something else ?

@SGaist This is just an example showing what I do in my actual service.

You can use canConvert.

@SGaist The value in the returned QDBusVariant is QDBusArgument in this case, so I cannot cast to QVariant from it.
