attach more widgets to a QScrollArea

[franco.amato]

you can do it like this:

QWidget w = new QWidget(this);
QVBoxLayout *lo = new QVBoxLayout;
lo->addWidget(m_TimeDisplay);
lo->addWidget(m_WaveDisplay);
w->setLayout(lo);
sa->setWidget(w);

QWidget w = new QWidget(this);
QVBoxLayout *lo = new QVBoxLayout;
lo->addWidget(m_TimeDisplay);
lo->addWidget(m_WaveDisplay);
w->setLayout(lo);
sa->setWidget(w);

To copy to clipboard, switch view to plain text mode 

It works, thank you
