Method Detail

chop

public java.awt.geom.Point2D.Double chop(java.awt.geom.Point2D.Double from)

This is a default implementation that chops the point at the rectangle returned by getBounds() of the figure.

Figures which have a non-rectangular shape need to override this method.

FIXME Invoke chop on each child and return the closest point.
