Class SystemColor

Implemented Interfaces:
Paint, Serializable, Transparency
public final class SystemColor
extends Color
implements Serializable
This class contains the various "system colors" in use by the native windowing system. The getRGB() method is dynamic on systems which support dynamic system color changes, and most methods in the superclass are written to use this dynamic value when reporting colors. However, the equals() method is not dynamic, and does not track the actual color of instances in this class. This means that equals may give surprising results; you are better off relying on getRGB.
Since:
1.1

Method Details

createContext

public PaintContext createContext(ColorModel cm,
                                  Rectangle deviceBounds,
                                  Rectangle2D userBounds,
                                  AffineTransform xform,
                                  RenderingHints hints)
Returns a paint context, used for filling areas of a raster scan with the current value of this system color. Since the system colors may be dynamically updated, the returned value may not always be the same; but as the system color is solid, the context does not need any of the passed parameters to do its job.
Specified by:
createContext in interface Paint
Overrides:
createContext in interface Color
Parameters:
cm - the requested color model
deviceBounds - the bounding box in device coordinates, ignored
userBounds - the bounding box in user coordinates, ignored
xform - the bounds transformation, ignored
hints - any rendering hints, ignored
Returns:
a context for painting this solid color

getRGB

public int getRGB()
Returns the RGB value for this color, in the sRGB color space. The blue value will be in bits 0-7, green in 8-15, red in 6-23, and the alpha value (bits 24-31) is 0xff. This is dynamically updated, so it may not match the results of getRed(), getGreen(), or getBlue().
Overrides:
getRGB in interface Color
Returns:
the current RGB value

toString

public String toString()
Returns a string describing this color. This is in the format "java.awt.SystemColor[i=" + index + ']', where index is one of the integer constants of this class. Unfortunately, this description does not describe the current value of the color; for that you should use new Color(syscolor.getRGB()).toString().
Overrides:
toString in interface Color
Returns:
a string describing this color
