Abridged code:

@
MainWindow::MainWindow(QWidget *parent)
: QMainWindow(parent)
{
QWidget centralWidget = new QWidget;

centralLayout = new QHBoxLayout;

aclockLayout = new QHBoxLayout;
aclockLayout->addWidget(aclock, 0, Qt::AlignCenter);

counterLayout = new QVBoxLayout;
counterlayout->addWidget(vbclock, 0, Qt::AlignHCenter);
counterlayout->addWidget(dtdisplay, 0 Qt::AlignHCenter);
counterLayout->addWidget(tzdisplay, 0, Qt::AlignHCenter);

centralLayout->addLayout(aclockLayout);
centralLayout->addLayout(counterLayout);
centralWidget->setLayout(centralLayout);
setCentralWidget(centralWidget);

}
@

All I want is for my three widgets to be aligned on the vertical center line of the QVBoxLayout. What am I missing here?
