Function Documentation

distanceToSegment()

qreal anonymous_namespace{autobreakconductor.cpp}::distanceToSegment	(	const QPointF &	point,
		const QLineF &	segment )

distanceToSegment

Parameters

point	: point to measure from
segment	: the finite segment (not the infinite line through it)

Returns

the distance from point to the closest point actually on segment. Unlike QET::orthogonalProjection(), which reports a hit for any point on the segment's infinite extension, this clamps the projection to the segment itself: a point collinear with a wire but past its actual drawn end is correctly reported as far away, not "on" the wire.
