public class PaintedFigure
extends AbstractFigure

A PaintedFigure is contains an arbitrary set of PaintedObjects in a list. This figure can be used for constructing more complex figures than classes such as BasicFigure. It contains a transform that is used for scaling the contained painted objects. (Note that, if using this class to construct a figure from an external source, the initial transform should operate on the coordinates only.)

Field Detail

_composite

private java.awt.Composite _composite

The color compositing operator

_transform

private java.awt.geom.AffineTransform _transform

The transform for the internals

_paintedList

private PaintedList _paintedList

The list containing the objects that we paint

Constructor Detail

PaintedFigure

public PaintedFigure()

Create a new blank figure.

PaintedFigure

public PaintedFigure(PaintedList objects)

Create a new figure that paints itself using the given PaintedList.

Method Detail

add

public void add(PaintedObject po)

Add a new painted object to the objects displayed by this figure.

getPaintedList

public PaintedList getPaintedList()

Get the painted list of painted objects of this figure.

getBounds

public java.awt.geom.Rectangle2D getBounds()

Get the bounding box of this figure.

Specified by:

getBounds in interface Figure

Overrides:

getBounds in class AbstractFigure

getOrigin

public java.awt.geom.Point2D getOrigin()

Return the origin, which is the point relative to which all of the contained objects are drawn.

Specified by:

getOrigin in interface Figure

Overrides:

getOrigin in class AbstractFigure

Returns:

The origin.

See Also:

AbstractFigure.getBounds()

getShape

public java.awt.Shape getShape()

Get the shape of this figure. This is the same as the bounding box.

Specified by:

getShape in interface Figure

Specified by:

getShape in class AbstractFigure

getComposite

public java.awt.Composite getComposite()

Get the color composition operator of this figure.

paint

public void paint(java.awt.Graphics2D g)

Paint the figure.

Specified by:

paint in interface VisibleComponent

Specified by:

paint in class AbstractFigure

setComposite

public void setComposite(java.awt.Composite c)

Set the color composition operator of this figure. If the composite is set to null, then the composite will not be changed when the figure is painted. By default, the composite is set to opaque.

transform

public void transform(java.awt.geom.AffineTransform at)

Transform the figure with the supplied transform. This can be used to perform arbitrary translation, scaling, shearing, and rotation operations.

Specified by:

transform in interface Figure

Specified by:

transform in class AbstractFigure
