Radiance look and feel - fill painters

The only painting method in RadianceFillPainter is

  /**
   * Fills the contour that matches the specified parameters.
   *
   * @param g
   *            Graphics context.
   * @param comp
   *            Component to paint.
   * @param width
   *            Width of a UI component.
   * @param height
   *            Height of a UI component.
   * @param contour
   *            Contour of a UI component.
   * @param fillScheme
   *            The fill color scheme.
   */
  public void paintContourBackground(Graphics g, Component comp, int width,
      int height, Shape contour, RadianceColorScheme fillScheme);

The contour parameter specifies the actual shape to fill and the fillScheme specifies the Radiance color scheme to be used to compute the colors. Specific implementations may choose to use offscreen images if the target visuals are not achievable with direct rendering APIs on the passed graphics context.

Important thing to note - a fill painter must not paint the focus ring or the border; these are painted separately.

Radiance provides a number of fill painters that can be used as a starting point for your custom application visuals.

• FractionBasedFillPainter enables vertical gradients with arbitrary multi-stop colors. Most core Radiance fill painters extend this class.
• SpecularRectangularFillPainter allows adding specular shine along the top part of the fill area.

Management API

If you wish to use the fill painter of the current skin to provide additional custom painting in your application, call:

• RadianceThemingCortex.GlobalScope.getCurrentSkin() to retrieve the current skin.
• RadianceSkin.getFillPainter() to retrieve the fill painter of the current skin.
• RadianceFillPainter.paintContourBackground() to paint the background on the specific graphics context.
