#include <QVariant>
struct st
{
public:
    int a;
    QString str;
};
/*下面的宏让自定义类型能被QVariant识别
*/
Q_DECLARE_METATYPE(st);
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    st one;
    one.a = 1;
    one.str = "ff";

    QVariant var;
    var.setValue(one);

    st x = var.value<st>();
    printf("%d", x.a);
    return a.exec();
}
