Member Function Documentation

◆ AddSpannedElement()

void vrv::FloatingCurvePositioner::AddSpannedElement ( CurveSpannedElement * spannedElement )

inline

Add a CurveSpannedElement to the FloatingCurvePositioner.

The element is owned by the positioner.

◆ CalcAdjustment()

int vrv::FloatingCurvePositioner::CalcAdjustment	(	const BoundingBox *	boundingBox,
		bool &	discard,
		int	margin = `0`,
		bool	horizontalOverlap = `true`
	)		const

Calculate the adjustment needed for an element for the curve not to overlap with it.

Discard will be true if the element already fits.
