jpicedt.graphic.view.DefaultHighlighterFactory.DefaultHighlighter

jpicedt.graphic.view.DefaultHighlighterFactory.AbstractCurveHighlighter

All Implemented Interfaces:

Highlighter

Enclosing class:

DefaultHighlighterFactory

public class DefaultHighlighterFactory.AbstractCurveHighlighter
extends DefaultHighlighterFactory.DefaultHighlighter

a Highlighter for any concrete implementation of jpicedt.graphic.model.AbstractCurve. This comprises tangents for non-straight segments, and is wrapped into a GeneralPath.

Constructor	Description
AbstractCurveHighlighter(AbstractCurve curve)	construct a new Highlighter for the given curve

Method Summary

Modifier and Type	Method	Description
void	paint(java.awt.Graphics2D g, java.awt.geom.Rectangle2D allocation, double scale)	Render the Highlighter to the given graphic context. Current implementation paints end-points using the highlighter color if the given allocation intersects the bounds of this view, then renders tangents, finally paint first subdivision-point in black to help user know where closed-curve start exactly.
protected void	syncShape(double scale)	Synchronizes the highlighter's tangents with the model.

Constructor Detail

AbstractCurveHighlighter

public AbstractCurveHighlighter(AbstractCurve curve)

construct a new Highlighter for the given curve

Method Detail

syncShape

protected void syncShape(double scale)

Synchronizes the highlighter's tangents with the model.

Overrides:

syncShape in class DefaultHighlighterFactory.DefaultHighlighter

Parameters:

scale - The current scale factor from-model-to-screen for the Graphics2D context ; this may be used to scale down line thickess, etc... so that e.g. barbells appear with the same size on the screen whatever the scale factor being set to the graphic context.

paint

public void paint(java.awt.Graphics2D g,
                  java.awt.geom.Rectangle2D allocation,
                  double scale)

Render the Highlighter to the given graphic context.
Current implementation paints end-points using the highlighter color if the given allocation intersects the bounds of this view, then renders tangents, finally paint first subdivision-point in black to help user know where closed-curve start exactly.

Specified by:

paint in interface Highlighter

Overrides:

paint in class DefaultHighlighterFactory.DefaultHighlighter

Parameters:

scale - The current scale factor from model to screen for the Graphics2D context ; this may be used to scale down line thickess, etc... so that lines/rectangle/... appear with the same length on the screen whatever the scale factor that's set to the graphic context.

allocation - current clipping
