Constructor Detail

ConstrainedControlPointHandle

public ConstrainedControlPointHandle(PolySplineConnection owner,
                                     int splineIndex,
                                     int splineIndex2)

Constructs a poly line control point handle.

Parameters:

owner - The owning polyline figure

splineIndex - Spline index of the point this controlpoint belongs to

splineIndex2 - Spline index of a second point that determines the initial distance
