Classes
struct	ConduitHit

Functions
ConduitHit	pickConduit (const MapCanvas *canvas, const QPoint &pixel)
	Hit-test CONDUITS only (pumps, weirs, orifices and outlets have no length to divide) across the canvas's visible SWMM model layers, with a 12-pixel tolerance at the current zoom. Computes the arclength position t of the closest point, kept off the ends so no sliver conduit results, and whether the conduit is a STREET section.

pickConduit()

ConduitHit ConduitSplitPick::pickConduit	(	const MapCanvas *	canvas,
		const QPoint &	pixel
	)

Hit-test CONDUITS only (pumps, weirs, orifices and outlets have no length to divide) across the canvas's visible SWMM model layers, with a 12-pixel tolerance at the current zoom. Computes the arclength position t of the closest point, kept off the ends so no sliver conduit results, and whether the conduit is a STREET section.

Returns

An invalid hit when nothing qualifies.
