public class ResizablePolygonAttribute
extends FilledShapeAttribute

This is an attribute that is rendered as a polygon. The vertices parameter is an array of doubles that specify the vertices of the polygon in the form {x1, y1, x2, y2, ... }. The width and height parameters, somewhat awkwardly, are used to specify the overall width and height. The polygon will be scaled to fit the specified width and height.

Field Detail

vertices

public Parameter vertices

The amount of vertices of the corners. This is a double that defaults to 0.0, which indicates no vertices. The default value specifies a rhombus.

Constructor Detail

ResizablePolygonAttribute

public ResizablePolygonAttribute(NamedObj container,
                                 java.lang.String name)
                          throws IllegalActionException,
                                 NameDuplicationException

Construct an attribute with the given name contained by the specified container. The container argument must not be null, or a NullPointerException will be thrown. This attribute will use the workspace of the container for synchronization and version counts. If the name argument is null, then the name is set to the empty string. Increment the version of the workspace.

Parameters:

container - The container.

name - The name of this attribute.

Throws:

IllegalActionException - If the attribute is not of an acceptable class for the container, or if the name contains a period.

NameDuplicationException - If the name coincides with an attribute already in the container.

Method Detail

attributeChanged

public void attributeChanged(Attribute attribute)
                      throws IllegalActionException

React to a changes in the attributes by changing the icon.

Overrides:

attributeChanged in class FilledShapeAttribute

Parameters:

attribute - The attribute that changed.

Throws:

IllegalActionException - If the change is not acceptable to this container (should not be thrown).

clone

public java.lang.Object clone(Workspace workspace)
                       throws java.lang.CloneNotSupportedException

Clone the object into the specified workspace. The new object is not added to the directory of that workspace (you must do this yourself if you want it there). The result is an object with no container.

Overrides:

clone in class FilledShapeAttribute

Parameters:

workspace - The workspace for the cloned object.

Returns:

The new Attribute.

Throws:

java.lang.CloneNotSupportedException - Not thrown in this base class

See Also:

NamedObj.exportMoML(Writer, int, String), NamedObj.setDeferringChangeRequests(boolean)

_newShape

protected java.awt.Shape _newShape()

Return the a new polygon with the given vertices.

Specified by:

_newShape in class FilledShapeAttribute

Returns:

A new shape.
