          eu.webtoolkit.jwt.WPolygonArea

public class WPolygonArea
extends WAbstractArea

An interactive area in a widget, specified by a polygon.

The area may be added to a WImage or WPaintedWidget to provide interactivity on a polygon area of the image. The polygon is specified in pixel coordinates, and uses an even-odd winding rule (overlaps create holes).

The polygon area corresponds to the HTML <area shape="poly"> tag.

WPolygonArea

public WPolygonArea()

Creates an empty polygon.

Defines an empty polygon.

WPolygonArea

public WPolygonArea(java.util.List<WPoint> points)
