Looked up into the sources, here is the line that queries a 
QDialogButtonBox::ButtonLayout (file qdialogbuttonbox.cpp @line 332).

layoutPolicy = QDialogButtonBox::ButtonLayout(q->style()-
>styleHint(QStyle::SH_DialogButtonLayout, 0, q));

So basically, all you need to do is to query the correct styleHint for your 
application current style.
