Class GeneralPathNodePainter

java.lang.Object
  y.view.AbstractCustomNodePainter
      y.view.GeneralPathNodePainter

All Implemented Interfaces:

GenericNodeRealizer.ContainsTest, GenericNodeRealizer.Painter

public class GeneralPathNodePainter
extends AbstractCustomNodePainter
implements GenericNodeRealizer.ContainsTest

A painter and contains test for GenericNodeRealizer that uses a pre-defined GeneralPath as the shape for nodes. GeneralPath instances that are used with this painter/contains test have to reside in the unit square, i.e. the bounds of these paths must lie in [0,1]x[0,1].

Constructor Summary

GeneralPathNodePainter(java.awt.geom.GeneralPath path)
Initializes a new GeneralPathNodePainter instance.

Method Summary

boolean	contains(NodeRealizer context, double x, double y) Used as a callback for the GenericNodeRealizer.contains(double, double) method.
protected java.awt.Color	getFillColor(NodeRealizer context, boolean selected) Returns the fill color for the specified realizer.
protected void	paintNode(NodeRealizer context, java.awt.Graphics2D graphics, boolean sloppy) Callback method to be overwritten by subclasses called by AbstractCustomNodePainter.paint(NodeRealizer, Graphics2D).

Constructor Detail

GeneralPathNodePainter

public GeneralPathNodePainter(java.awt.geom.GeneralPath path)

Initializes a new GeneralPathNodePainter instance.

Parameters:

path - the geometric shape used to represent nodes. Its bounds must lie in [0,1]x[0,1].

Method Detail

paintNode

protected void paintNode(NodeRealizer context,
                         java.awt.Graphics2D graphics,
                         boolean sloppy)

Description copied from class: AbstractCustomNodePainter

Callback method to be overwritten by subclasses called by AbstractCustomNodePainter.paint(NodeRealizer, Graphics2D). This method is responsible for drawing the actual node only - neither the hotspots, nor the labels, should be painted by this method.

Specified by:

paintNode in class AbstractCustomNodePainter

Parameters:

context - the context node

graphics - the graphics context to use

sloppy - whether to draw the node sloppily

AbstractCustomNodePainter.initializeLine(NodeRealizer, Graphics2D), AbstractCustomNodePainter.initializeFill(NodeRealizer, Graphics2D)

getFillColor

protected java.awt.Color getFillColor(NodeRealizer context,
                                      boolean selected)

Returns the fill color for the specified realizer. Overwritten to always consider the specified realizer to be not selected.

Overrides:

getFillColor in class AbstractCustomNodePainter

Parameters:

selected - ignored. Always considered to be false.

context - the context node

Returns:

the color to use or null

contains

public boolean contains(NodeRealizer context,
                        double x,
                        double y)

Description copied from interface: GenericNodeRealizer.ContainsTest

Used as a callback for the GenericNodeRealizer.contains(double, double) method.

Specified by:

contains in interface GenericNodeRealizer.ContainsTest
