Access an QHBoxLayout, which name you don't know

[wysota]

Something like this would be better:

QHBoxLayout *l = qobject_cast<QHBoxLayout *>(gb->layout());
if(l) l->setDirection( QBoxLayout::TopToBottom );

QHBoxLayout *l = qobject_cast<QHBoxLayout *>(gb->layout());
if(l) l->setDirection( QBoxLayout::TopToBottom );
