Member Function Documentation

◆ endNear()

CableItem::GrabbedEnd Dataflow::CableItem::endNear ( QPointF  scenePos,
QPointF  p1,
QPointF  p2 
)
staticnoexcept

Which end a press at scenePos would unplug and re-route. Both ends match on a cable too short to tell them apart; the sink wins there, as that is the end one usually means to move.

◆ grabZoneRadius()

double Dataflow::CableItem::grabZoneRadius ( QPointF  p1,
QPointF  p2 
)
staticnoexcept

How far from an end a press still grabs it. The innermost pixels belong to the port, which starts a new cable instead, so the zone has to clear PortItem::hitRadius by enough to be aimed at without magnifying the view.
