QGroupBox expands to maximum in BoxLayout

[olidem]

Hi!

I have added a QGoupBox to my QVBoxLayout.
The QGroupBox itself also holds a QVBoxLayout.

QVBoxLayout * outer = new QVBoxLayout;
outer->addWidget(new QPushButton("A"));
outer->addWidget(new QPushButton("B"));
 
QGroupBox * box = new QGroupBox("title");
QVBoxLayout * inner = new QVBoxLayout;
inner->addWidget(new QRadioButton("Poss A"));
inner->addWidget(new QRadioButton("Poss B"));
box->setLayout(inner);
box->setSizePolicy(QSizePolicy::Minimum,QSizePolicy::Minimum); //doesn't help :-(
outer->addWidget(box);
 
outer->addWidget(new QPushButton("C"));
outer->addWidget(new QPushButton("D"));

QVBoxLayout * outer = new QVBoxLayout;
outer->addWidget(new QPushButton("A"));
outer->addWidget(new QPushButton("B"));

QGroupBox * box = new QGroupBox("title");
QVBoxLayout * inner = new QVBoxLayout;
inner->addWidget(new QRadioButton("Poss A"));
inner->addWidget(new QRadioButton("Poss B"));
box->setLayout(inner);
box->setSizePolicy(QSizePolicy::Minimum,QSizePolicy::Minimum); //doesn't help :-(
outer->addWidget(box);

outer->addWidget(new QPushButton("C"));
outer->addWidget(new QPushButton("D"));

To copy to clipboard, switch view to plain text mode 

In this example, the QPushButtons automatically have "unit" height, but are horizontally expanded to maximum width.

The GroupBox also expands to maximal height, which I do not want.

So, my concern is to find a way, s.t. the group box only takes as much space as it really needs to display its contents, i.e. the two QRadioButtons.

Thank you for your help in advance,
Best regards,
Oliver
