QArrow

scalation.scala2d.QArrow
case class QArrow(var p1: R2, var pc: R2, var p2: R2, len: Int) extends Double, CurvilinearShape

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.

Value parameters

len

the length of the arrowhead on the curve/arc

p1

the starting point for the curve/arc

p2

the ending point for the curve/arc

pc

the control point for the curve/arc
