How do I make the scrollbars show of a QScrollArea?

How do I make the scrollbars show of a QScrollArea show? I put some QWidgets in the QScrollArea then I resize the QScrollArea though code. Some of the QWidgets in the QScrollArea was hidden and the scrollbars wasn't showing. So how do I make it work right?

Set the scrollBarPolicy to allways on and that should do it...

@
QScrollArea *area = new QScrollArea();
area->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOn);
area->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOn);

In what way "doesn't work"? Without a bit more information or seeing your code its difficult to offer any specific help, but the following is a working example:

@
#include <QtGui>

class Widget : public QWidget {
public:
Widget(QWidget *parent=0) : QWidget(parent) {
QVBoxLayout *l=new QVBoxLayout(this);

    QScrollArea *s=new QScrollArea;
    l->addWidget(s);

    QWidget *w=new QWidget(this);
    QVBoxLayout *wl=new QVBoxLayout(w);

    for(int i=0; i<10; i++)
        wl->addWidget(new QLabel(QString("Label %1").arg(i)));

    s->setWidget(w);
    setGeometry(100, 100, 100, 100);
}

};

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
Widget w;
w.show();

return a.exec();

}

The window should start off very small with both vertical and horizontal scrollbars visible, when the window is resized they will disappear and appear appropriately. Hope this helps ;o)
