[Interest] How to use QStyle.sizeFromContents with QStyleOptionFrame?

Hi Everybody, 

Using Qt 5.5.0 from installed binaries, in my QFrame based custom widget
sizeHint override I want to have: 

	QSize contentSize = ....;

	QStyleOptionFrame optFrame;
	QSize styleSize = style()->sizeFromContents( QStyle::CT_Frame,
optFrame, contentSize, this );

But of course, CT_Frame doesn't exist!  So how can I make this work?  A
global style sheet is used to produce different frame borders, padding,
background colors, etc.  

Thanks in advance,
