Field Detail

stroke

public java.awt.Stroke stroke

The stroke.

shape

public java.awt.Shape shape

The shape being painted.

strokePaint

public java.awt.Paint strokePaint

The stroke paint.

_strokes

private static java.awt.BasicStroke[] _strokes

A static array of cached strokes

Constructor Detail

AbstractPaintedGraphic

public AbstractPaintedGraphic()

Method Detail

getLineWidth

public abstract float getLineWidth()

Get the line width.

Specified by:

getLineWidth in interface PaintedGraphic

getBounds

public java.awt.geom.Rectangle2D getBounds()

Get the bounding box of the shape when stroked. This method takes account of the thickness of the stroke.

Specified by:

getBounds in interface PaintedObject

getStroke

public java.awt.Stroke getStroke()

Get the stroke.

Specified by:

getStroke in interface PaintedGraphic

getStroke

public static java.awt.BasicStroke getStroke(int width)

Get a new stroke of the given width and with no dashing. This method will generally return an existing stroke object, and can be used to save creating zillions of Stroke objects.

getStroke

public static java.awt.BasicStroke getStroke(float floatwidth)

Get a new stroke of the given width and with no dashing. This method will return an existing stroke object if the width is integer-valued and has a reasonably small width. This method can be used to save creating zillions of Stroke objects.

hit

public abstract boolean hit(java.awt.geom.Rectangle2D r)

Test if this shape intersects the given rectangle. Currently this does not take into account the width of the stroke or other things such as dashes, because of problems with geometry testing with GeneralPath in the first version of JDK1.2.

Specified by:

hit in interface PaintedGraphic

setLineWidth

public abstract void setLineWidth(float lineWidth)

Set the line width.

Specified by:

setLineWidth in interface PaintedGraphic
