The following members of class QStyleOptionGraphicsItem are obsolete. They are provided to keep old source code working. We strongly advise against using them in new code.
Use QStyleOptionGraphicsItem::levelOfDetailFromTransform() together with QPainter::worldTransform() instead.
This variable holds the complete transformation matrix for the item
The QMatrix provided through this member does include information about any perspective transformations applied to the view or item. To get the correct transformation matrix, use QPainter::transform() on the painter passed into the QGraphicsItem::paint() implementation.
This matrix is the combination of the item's scene matrix and the matrix of the painter used for drawing the item. It is provided for convenience, allowing anvanced level-of-detail metrics that can be used to speed up item drawing.
This member is only initialized for items that have the QGraphicsItem::ItemUsesExtendedStyleOption flag set.
