• This property holds the way in which the form's rows wrap.If you want to display each label above its associated field (instead of next to it), set this property to WrapAllRows.

formLayout->setRowWrapPolicy(QFormLayout::WrapAllRows)

• This property holds the way in which the form's fields grow.If none of the fields can grow and the form is resized, extra space is distributed according to the current form alignment as given figure below

formLayout->setFieldGrowthPolicy(QFormLayout::FieldsStayAtSizeHint);
