public PaintUtils()

Method Detail

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 biggestStroke)

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

biggestStroke - the widest stroke to use.

drawBevel

public static void drawBevel(Graphics 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.

drawColors

private static void drawColors(Color[] colors,
                               Graphics g,
                               int x1,
                               int y1,
                               int x2,
                               int y2,
                               int direction)
