В QList вложить разного типа контейнера, В QList вложить разного типа контейнера Опции

[fortero]

Доброе время суток!
У меня есть необходимость контейнеры такого типа к примеру:

QList<QString> list1;
list1 <<"String1" <<"String2";
QList<int> list2;
list2 << 10 << 20;
QList<QLabel*> list3;
list3 << new QLabel("LB1") << new QLabel("LB2");

Все три контейнера сложить в один контейнер как это сделать?
Я думал так:

QList<QVariant> varList;
varList << QVariant(list1) << QVariant(list2) << QVariant(list3);

Но так не выходит уже когда QList<int> помещаю отказывается компилится, за QLabel я вообще молчу. Что делать? Или есть более изящный вариант решения данной задачи???
Спасибо за внимание!

QList<QVariant> varList;
varList << QVariant(list1) << QVariant(list2) << QVariant(list3);

Это потому что у QVariant нет конструктора QVariant::QVariant ( const QList<int> & val ) и т.д. Да и тип QList<int> не зарегистрирован для него.
Можно так сделать:
