public class PolygonItem
extends PathBasedItem

A closed, filled/stroked polygon defined in world coordinates.

The polygon geometry is stored as a world-coordinate Path2D. Selection/reshape modifies vertices of that path.

Constructor Details

PolygonItem

public PolygonItem(Layer layer,
 Point2D.Double[] points,
 Object... keyVals)

Create a world polygon item

Parameters:

layer - the z layer this item is on.

points - the points of the polygon

keyVals - optional key value pairs for styling the item.

PolygonItem

public PolygonItem(Layer layer,
 Point2D.Double[] points)

Create a world polygon item

Parameters:

layer - the z layer this item is on.

points - the points of the polygon

PolygonItem

public PolygonItem(Layer layer)

Create a world polygon item

Parameters:

layer - the z layer this item is on.

Method Details

setPath

public void setPath(Point2D.Double[] points)

Set the path from a world polygon.

Parameters:

points - the points of the polygon.

reshape

protected void reshape()

Reshape the polygon based on the modification. Not much we can do to a polygon except move the selected point. Keep in mind that if control or shift was pressed, the polygon will scale rather than coming here.

Overrides:
