QT 4.5 - how do I perform a queued connection with a template type?

Question

I am trying to do a connect with a std::vector& using queued connection

   connect(this, SIGNAL(process(QVector<FrameData*>&)), 
           this, SLOT(beginProcess(QVector<FrameData*>&),
           Qt::ConnectionType::QueuedConnection);

What parameters should I pass for QRegisterMetaType for this to work?

Thanks in advance!

Answer 1

std::vector or QVector? presumably the following should work,

int type = qRegisterMetaType< QVector<FrameData*> >("QVector<FrameData*>");

Answer 2

You can't use non-const references in signals and slots.

EDIT: ...when using Queued connections.
