Qt :如何获取特定类的子类的所有类

#include <QtCore>

class MyBaseClass
{
    Q_OBJECT
};

class MyDerivedClass1 : public MyBaseClass
{
    Q_OBJECT
};

class MyDerivedClass2 : public MyBaseClass
{
    Q_OBJECT
};

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    // 获取MyBaseClass的元对象
    const QMetaObject *baseMetaObject = MyBaseClass::staticMetaObject;

    // 获取MyBaseClass的类名
    const char *baseClassName = baseMetaObject->className();
    qDebug() << "Base class name:" << baseClassName;

    // 获取MyBaseClass的所有子类的类名
    QStringList subClassNames;
    for (int i = baseMetaObject->enumeratorOffset(); i < baseMetaObject->classInfoCount(); ++i) {
        const QMetaObject *metaObject = QMetaType::metaObjectForType(baseMetaObject->classInfo(i).value());
        if (metaObject) {
            const char *className = metaObject->className();
            subClassNames.append(className);
        }
    }
    qDebug() << "Sub class names:" << subClassNames;

    return a.exec();
}
