  jpicedt.graphic.view.highlighter.DefaultHighlighter
      jpicedt.graphic.view.highlighter.AbstractCurveHighlighter

All Implemented Interfaces:

Highlighter

public class AbstractCurveHighlighter
extends 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 Detail

AbstractCurveHighlighter

public AbstractCurveHighlighter(AbstractCurve curve,
                                DefaultHighlighterFactory f)

construct a new Highlighter for the given curve

Method Detail

getElement

public AbstractCurve getElement()

Description copied from interface: Highlighter

returns the higlighted Element

Specified by:

getElement in interface Highlighter

Overrides:

getElement in class DefaultHighlighter

Returns:

the higlighted Element.

syncShape

protected void syncShape(double scale)

Synchronizes the highlighter's tangents with the model.

Overrides:

syncShape in class 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(Graphics2D g,
                  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 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
