Maybe ... , but maybe also another application property which will say look or
don't look for ParentFont. Why ? Because parent control eg.
TPanel have ParentFont=False, but uses CourierNew font and 12 Size.
On TPanel is TBitBtn which says ParentFont=False, but uses pure default font.
So in your case both will have fonts as it is.
In my case TBitBtn will take application.DefaultFont, but TPanel won't because
it's font is different than "default".
