Inherited Methods

From class com.sun.java.swing.plaf.nimbus.AbstractRegionPainter

void	configureGraphics(Graphics2D g) Configures the given Graphics2D.
final float	decodeAnchorX(float x, float dx) Decodes and returns a float value representing the actual pixel location for the anchor point given the encoded X value of the control point, and the offset distance to the anchor from that control point.
final float	decodeAnchorY(float y, float dy) Decodes and returns a float value representing the actual pixel location for the anchor point given the encoded Y value of the control point, and the offset distance to the anchor from that control point.
final Color	decodeColor(Color color1, Color color2, float midPoint) Decodes and returns a color, which is derived from a offset between two other colors.
final Color	decodeColor(String key, float hOffset, float sOffset, float bOffset, int aOffset) Decodes and returns a color, which is derived from a base color in UI defaults.
final LinearGradientPaint	decodeGradient(float x1, float y1, float x2, float y2, float[] midpoints, Color[] colors) Given parameters for creating a LinearGradientPaint, this method will create and return a linear gradient paint.

From class java.lang.Object

Object	clone() Creates and returns a copy of this object.
boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.
void	finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
final Class<?>	getClass() Returns the runtime class of this `Object`.
int	hashCode() Returns a hash code value for the object.
final void	notify() Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll() Wakes up all threads that are waiting on this object's monitor.
String	toString() Returns a string representation of the object.
final void	wait() Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
final void	wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.

Public Constructors

public LoweredBorder ()

Public Methods

public Insets getBorderInsets (Component c)

Returns the insets of the border.

Parameters

c	the component for which this border insets value applies

public boolean isBorderOpaque ()

Returns whether or not the border is opaque. If the border is opaque, it is responsible for filling in it's own background when painting.

public void paintBorder (Component c, Graphics g, int x, int y, int width, int height)

Paints the border for the specified component with the specified position and size.

Parameters

c	the component for which this border is being painted
g	the paint graphics
x	the x position of the painted border
y	the y position of the painted border
width	the width of the painted border
height	the height of the painted border

Protected Methods

protected void doPaint (Graphics2D g, JComponent c, int width, int height, Object[] extendedCacheKeys)

Actually performs the painting operation. Subclasses must implement this method. The graphics object passed may represent the actual surface being rendererd to, or it may be an intermediate buffer. It has also been pre-translated. Simply render the component as if it were located at 0, 0 and had a width of width and a height of height. For performance reasons, you may want to read the clip from the Graphics2D object and only render within that space.

Parameters

g	The Graphics2D surface to paint to
c	The JComponent related to the drawing event. For example, if the region being rendered is Button, then `c` will be a JButton. If the region being drawn is ScrollBarSlider, then the component will be JScrollBar. This value may be null.
width	The width of the region to paint. Note that in the case of painting the foreground, this value may differ from c.getWidth().
height	The height of the region to paint. Note that in the case of painting the foreground, this value may differ from c.getHeight().
extendedCacheKeys	The result of the call to getExtendedCacheKeys()

protected Object[] getExtendedCacheKeys (JComponent c)

Get any extra attributes which the painter implementation would like to include in the image cache lookups. This is checked for every call of the paint(g, c, w, h) method.

Parameters

c	The component on the current paint call

Returns

Array of extra objects to be included in the cache key

protected AbstractRegionPainter.PaintContext getPaintContext ()

Gets the PaintContext for this painting operation. This method is called on every paint, and so should be fast and produce no garbage. The PaintContext contains information such as cache hints. It also contains data necessary for decoding points at runtime, such as the stretching insets, the canvas size at which the encoded points were defined, and whether the stretching insets are inverted.

This method allows for subclasses to package the painting of different states with possibly different canvas sizes, etc, into one AbstractRegionPainter implementation.

Returns

a PaintContext associated with this paint operation.
