Constructor & Destructor Documentation

◆ QGraphicsSceneIndexPrivate()

QGraphicsSceneIndexPrivate::QGraphicsSceneIndexPrivate ( QGraphicsScene *  scene)

Constructs a private scene index.

Definition at line 173 of file qgraphicssceneindex.cpp.

◆ ~QGraphicsSceneIndexPrivate()

QGraphicsSceneIndexPrivate::~QGraphicsSceneIndexPrivate ( )

Destructor of private scene index.

◆ 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.
