attach more widgets to a QScrollArea

[franco.amato]

Hi to all,
I'm able to attach a widget to a scrollarea. I would know if it's possible to attach more than one qwidget to the same scrollarea.
So when I move the scrollbar, both widgets should be moved.

I tried with this code:

/* scroll area */
QScrollArea* sa = new QScrollArea( this );
sa->setWidgetResizable( true );
sa->setVerticalScrollBarPolicy( Qt::ScrollBarAlwaysOff );
sa->setHorizontalScrollBarPolicy( Qt::ScrollBarAlwaysOn );
 
QScrollBar *scrollBar = sa->horizontalScrollBar();
 
m_WaveDisplay = new WaveDisplay; //QWidget
m_TimeDisplay = new TimeWidget;    //QWidget
 
sa->setWidget(m_TimeDisplay);
sa->setWidget(m_WaveDisplay);
 
QVBoxLayout* layout = new QVBoxLayout();
layout->addWidget( sa );
 
..more code..

/* scroll area */
QScrollArea* sa = new QScrollArea( this );
sa->setWidgetResizable( true );
sa->setVerticalScrollBarPolicy( Qt::ScrollBarAlwaysOff );
sa->setHorizontalScrollBarPolicy( Qt::ScrollBarAlwaysOn );

QScrollBar *scrollBar = sa->horizontalScrollBar();

m_WaveDisplay = new WaveDisplay; //QWidget
m_TimeDisplay = new TimeWidget;    //QWidget

sa->setWidget(m_TimeDisplay);
sa->setWidget(m_WaveDisplay);

QVBoxLayout* layout = new QVBoxLayout();
layout->addWidget( sa );

..more code..

To copy to clipboard, switch view to plain text mode 

but I get a crash when the application starts.
Maybe is not possible?

Best
