如何将QVariant转换为自定义类？

#include <QVariant>
#include <QObject>

class MyClass : public QObject
{
    Q_OBJECT
    Q_PROPERTY(int myProperty READ myProperty WRITE setMyProperty)

public:
    MyClass(QObject *parent = nullptr) : QObject(parent) {}

    int myProperty() const { return m_myProperty; }
    void setMyProperty(int value) { m_myProperty = value; }

private:
    int m_myProperty;
};

int main()
{
    QVariant variant;
    MyClass myObject;

    // 将 MyClass 对象转换为 QVariant
    variant.setValue(&myObject);

    // 将 QVariant 转换回 MyClass 对象
    MyClass *newObject = variant.value<MyClass *>();

    return 0;
}
