I am trying to add vertical and horizontal scrollbar to my listwidget, I wanted to show horizontal scrollbar whenever my text goes beyond the border, I tried keeping horizontal bar always on but no luck, any help is very much appreciated.

Code:

QScrollBar* makeItVertical(QWidget * pParent)
{
    QScrollBar * pScrollBar = new QScrollBar(Qt::Vertical, pParent);
    return pScrollBar;
}
QScrollBar* makeItHorizontal(QWidget * pParent)
{
    QScrollBar * pScrollBar = new QScrollBar(Qt::Horizontal, pParent);
    return pScrollBar;
}

My output: (No Horizontal bar)

Can someone please help, what I am doing wrong here?
