scroll items by using touching (dragging) without using scrollbar in QScrollArea

Binary Soft

Hi,
I add dynamically buttons in QScrollArea. I want scroll up and down by using touch items (drag with mouse or touch screen). I do not want to scroll from vertical scroll bar so I hide it.

How can I sove it?

Thanks

/QScrollArea *scrollArea = new QScrollArea( this );
    scrollArea->setVerticalScrollBarPolicy( Qt::ScrollBarAlwaysOff );
    scrollArea->setWidgetResizable( true );
    scrollArea->setGeometry( 10, 10, 200, 200 );

    QWidget *widget = new QWidget();
    scrollArea->setWidget( widget );

    QVBoxLayout *layout = new QVBoxLayout();
    widget->setLayout( layout );

    for (int i = 0; i < 10; i++)
    {
        QPushButton *button = new QPushButton( QString( "%1" ).arg( i ) );
        layout->addWidget( button );
    }

Hi
And welcome to the forums.
I made a combobox touch scroll able by
QScroller::grabGesture(ui->combo->view()->viewport(),QScroller::LeftMouseButtonGesture);
I assume you can do something like for scrollArea too.
