Constructor Detail

EllipseHighlighter

public EllipseHighlighter(PicEllipse ellipse,
                          DefaultHighlighterFactory f)

construct a new Highlighter for the given ellipse

Method Detail

getElement

public PicEllipse 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)

Synchronize the "shape" variable 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 paint the surrounding parallelogram.

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
