Documentación del constructor y destructor

QSpacerItem::QSpacerItem	(	int	w,
		int	h,
		QSizePolicy::SizeType	hData = QSizePolicy::Minimum,
		QSizePolicy::SizeType	vData = QSizePolicy::Minimum
	)		[inline]

Constructs a spacer item with preferred width w, preferred height h, horizontal size policy hData and vertical size policy vData.

The default values provide a gap that is able to stretch if nothing else wants the space.

QSpacerItem::QSpacerItem	(	int	w,
		int	h,
		QSizePolicy::SizeType	hData = QSizePolicy::Minimum,
		QSizePolicy::SizeType	vData = QSizePolicy::Minimum
