Constructor & Destructor Documentation

◆ QGraphicsSceneIndexPrivate()

QGraphicsSceneIndexPrivate::QGraphicsSceneIndexPrivate ( QGraphicsScene * scene)

Constructs a private scene index.

Definition at line 175 of file qgraphicssceneindex.cpp.

References scene.

◆ ~QGraphicsSceneIndexPrivate()

QGraphicsSceneIndexPrivate::~QGraphicsSceneIndexPrivate ( )

Destructor of private scene index.

Definition at line 182 of file qgraphicssceneindex.cpp.

Member Function Documentation

◆ init()

void QGraphicsSceneIndexPrivate::init ( )

Definition at line 302 of file qgraphicssceneindex.cpp.

References scene.

◆ itemCollidesWithPath()

bool QGraphicsSceneIndexPrivate::itemCollidesWithPath ( const QGraphicsItem * item,
const QPainterPath & path,
Qt::ItemSelectionMode mode )
static

Checks if item collides with the path and mode, but also checks that if it doesn't collide, maybe its frame rect will.

Definition at line 192 of file qgraphicssceneindex.cpp.

◆ items_helper()

void QGraphicsSceneIndexPrivate::items_helper ( const QRectF & rect,
QGraphicsSceneIndexIntersector intersect,
QList< QGraphicsItem * > * items,
const QTransform & viewTransform,
Qt::ItemSelectionMode mode,
Qt::SortOrder order,
const void * intersectData ) const
inline

Definition at line 107 of file qgraphicssceneindex_p.h.

◆ recursive_items_helper()

void QGraphicsSceneIndexPrivate::recursive_items_helper ( QGraphicsItem * item,
QRectF exposeRect,
QGraphicsSceneIndexIntersector intersect,
QList< QGraphicsItem * > * items,
const QTransform & viewTransform,
Qt::ItemSelectionMode mode,
qreal parentOpacity,
const void * intersectData ) const

This function returns the items in ascending order.
