How to add a scrollbar to parent QWidget

Question

Hi,

I understand how to add a scrollArea to a particular widget. However in my case Qwidget has multiple child widgets and these are all set using QVBoxLayout. Now how can I add a scroll bar in this case. Here QWidget is not center widget, its one of the pages of the TabWidget. My code look like:

QTabWIdget *center = new QTabWidget; setCentralWIdget(center);

xTab = new QWidget;

formLayout = new QFormLayout; formLayout->addWidget(...); formLayout->addWidget(...); formLayout->addWidget(...); formLayout->addWidget(...);

xTab->setLayout(formLayout);

Now how can I set the scrollBar to xTab. I tried using like scrollArea = new QScrollArea; scrollArea->setWidget(xTab);

however this isn't working.

Any idea/suggestions are helpful and appreciated.

Have you tried using QScrollArea as the tab page?

QTabWIdget *center = new QTabWidget; setCentralWIdget(center);

xTab = new QScrollArea; 
formLayout = new QFormLayout; formLay....
xTab->setLayout(formLayout);
center->addTab(xTab, "XXX Tab");
