case class QArrow(p1: R2 = R2 (0.0, 0.0), pc: R2 = R2 (0.0, 0.0), p2: R2 = R2 (0.0, 0.0), len: Int = 10) extends Double with CurvilinearShape with Product with Serializable

The QArrow class uses Java's Path2D class to create a quad curve with an arrowhead on the far end. The main curve is defined by points 'p1' and 'p2' along with a control point 'pc'. Points 'p3' and 'p4' are the corners of the triangular arrowhead.

p1

the starting point for the curve/arc

pc

the control point for the curve/arc

p2

the ending point for the curve/arc

len

the length of the arrowhead on the curve/arc
