public class PolygonShape

extends BaseVertexShape

Class PolygonShape defines a polygon using vertex data.

This class is a BaseVertexShape whose Path.Strategy is fixed to be Path.POLYGON.

This class does not use the tangent array inherited from BaseShape.

To avoid confusion with the class java.awt.Polygon, we name this class PolygonShape. Our version of a polygon is more general than the Java class since the internal coordinates are floating point and since the user may choose the closure mode and winding rule.

Since:

2.4.0

Version:

2.4.0

Field Summary

static String	ADD_VERTEX Bound property name to add one vertex.
static String	REMOVE_VERTEX Bound property name to remove one vertex.
static String	SET_VERTEX Bound property name to set one vertex.
static String	SET_VERTEX_DATA Bound property name to set the vertex data.
