QScrollArea nested layouts

[guy incognito]

Hi all,

I got some problems with the QScrollArea. Following code creates a Qt3DWindow in a windowContainer.
This container is embedded in a QHBoxLayout along with a QVBoxLayout which contains several other widgets (like buttons).
For the case that the QVBoxLayout gets stuffed with too many widget I would like to make i scrollable but my approaches were not satisfying.

original code which works fine (without scrolling):

QWidget* container = QWidget::createWindowContainer(view); // view => Window3D
QSize screenSize = view->screen()->size();
container->setMinimumSize(QSize(200, 100));
container->setMaximumSize(screenSize);

QWidget* widget = new QWidget;
QHBoxLayout* hLayout = new QHBoxLayout(widget);
QVBoxLayout* vLayout = new QVBoxLayout;

vLayout->setAlignment(Qt::AlignTop);
hLayout->addWidget(container, 1);
hLayout->addLayout(vLayout);

scolling approach:

QWidget* widget = new QWidget;
QHBoxLayout* hLayout = new QHBoxLayout(widget);

QWidget* widget2 = new QWidget;
QVBoxLayout* vLayout = new QVBoxLayout(widget2);

vLayout->setAlignment(Qt::AlignTop);
hLayout->addWidget(container, 1);
hLayout->addWidget(widget2);

QScrollArea* area = new QScrollArea;
area->setWidget(widget); // whole layout is scrollable
//area->setWidget(widget2); // only vLayout is displayed (and scrollable)
area->setWidgetResizable(true);

Edit:
This is from the Qt3D example "basicshapes". I want to make the verticalLayout at the right scrollable while the 3D view container stays the same size. The original code from above belongs to this.
