public final class SystemColor
extends Color
implements Serializable

A class to encapsulate symbolic colors representing the color of native GUI objects on a system. For systems which support the dynamic update of the system colors (when the user changes the colors) the actual RGB values of these symbolic colors will also change dynamically. In order to compare the "current" RGB value of a SystemColor object with a non-symbolic Color object, getRGB should be used rather than equals.

Note that the way in which these system colors are applied to GUI objects may vary slightly from platform to platform since GUI objects may be rendered differently on each platform.

System color values may also be available through the getDesktopProperty method on java.awt.Toolkit.

Method Detail

getRGB

public int getRGB()
Gets the "current" RGB value representing the symbolic color. (Bits 24-31 are 0xff, 16-23 are red, 8-15 are green, 0-7 are blue).

Overrides:
getRGB in class Color
Returns:
the RGB value of the color in the default sRGB ColorModel.
See Also:
ColorModel.getRGBdefault(), Color.getBlue(), Color.getGreen(), Color.getRed()

createContext

public PaintContext createContext(ColorModel cm,
                                  Rectangle r,
                                  Rectangle2D r2d,
                                  AffineTransform xform,
                                  RenderingHints hints)
Creates and returns a PaintContext used to generate a solid color pattern. This enables a Color object to be used as an argument to any method requiring an object implementing the Paint interface.

Specified by:
createContext in interface Paint
Overrides:
createContext in class Color
Parameters:
cm - the specified ColorModel
r - the specified Rectangle
r2d - the specified Rectangle2D
xform - the specified AffineTransform
hints - the specified RenderingHints
Returns:
a PaintContext that is used to generate a solid color pattern.
See Also:
Paint, PaintContext, Graphics2D.setPaint(java.awt.Paint)

toString

public String toString()
Returns a string representation of this Color's values. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not be null.

Overrides:
toString in class Color
Returns:
a string representation of this Color
