  • Method Details

    • getFocusRingColor

      public static Color getFocusRingColor()
      Returns:
      the color used to indicate when a component has focus. By default this uses the color (64,113,167), but you can override this by calling:
      UIManager.put("focusRing",customColor);
    • paintFocus

      public static void paintFocus(Graphics2D g, Shape shape, int pixelSize)
      Paints 3 different strokes around a shape to indicate focus. The widest stroke is the most transparent, so this achieves a nice "glow" effect.

      The catch is that you have to render this underneath the shape, and the shape should be filled completely.

      Parameters:
      g - the graphics to paint to
      shape - the shape to outline
      pixelSize - the number of pixels the outline should cover.
    • paintFocus

      public static void paintFocus(Graphics2D g, Shape shape, int pixelSize, Color focusColor, boolean changeRenderingHints)
      Paints 3 different strokes around a shape to indicate focus. The widest stroke is the most transparent, so this achieves a nice "glow" effect.

      The catch is that you have to render this underneath the shape, and the shape should be filled completely.

      Parameters:
      g - the graphics to paint to
      shape - the shape to outline
      pixelSize - the number of pixels the outline should cover.
      focusColor - the color of the focus ring to paint
      changeRenderingHints - if true then the rendering hints will be modified, if false they will be left in tact
    • drawBevel

      public static void drawBevel(Graphics2D g, Rectangle r)
      Uses translucent shades of white and black to draw highlights and shadows around a rectangle, and then frames the rectangle with a shade of gray (120).

      This should be called to add a finishing touch on top of existing graphics.

      Parameters:
      g - the graphics to paint to.
      r - the rectangle to paint.
    • getVerticalGradient

      static Paint getVerticalGradient(String name, int height, int y, float[] positions, Color[] colors)
      Create a vertical gradient. This gradient is stored in a table and reused throughout the rest of this session.
      Parameters:
      name - an identifying key for this gradient (used to cache it).
      height - the height of the gradient
      y - the y offset of the gradient
      positions - the fractional positions of each color (between [0,1]).
      colors - one color for each position.
      Returns:
      the vertical gradient.
