QObject::connect: Cannot queue arguments of type 'QVector'

不知道爲啥
我就加了類似下面的代碼

    item->setData(node.getSize(), Qt::DisplayRole);

報錯爲

QObject::connect: Cannot queue arguments of type 'QVector<int>'
(Make sure 'QVector<int>' is registered using qRegisterMetaType().)
QObject::connect: Cannot queue arguments of type 'QVector<int>'
