GuiWorkArea has no widget parent?

[Manoj Rajagopalan]

Hi,

   While browsing through LyX frontend code I noticed that GuiWorkArea has two 
constructors and neither seems to be passing any QWidget *parent to 
QAbstractScrollArea that GuiWorkArea inherits. Is the widget parenting being 
done somewhere else or does Qt4 guarantee some kind of automagic parenting?

Thanks,
Manoj
