doPaint	back to summary
protected void doPaint(Graphics2D g, JComponent c, int width, int height, Object[] extendedCacheKeys) Implements abstract javax.swing.plaf.nimbus.AbstractRegionPainter.doPaint. Actually performs the painting operation. Subclasses must implement this method. The graphics object passed may represent the actual surface being rendered 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:Graphics2D The Graphics2D surface to paint to c:JComponent 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:int The width of the region to paint. Note that in the case of painting the foreground, this value may differ from c.getWidth(). height:int The height of the region to paint. Note that in the case of painting the foreground, this value may differ from c.getHeight().

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

Implements abstract javax.swing.plaf.nimbus.AbstractRegionPainter.doPaint.

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.

Parameters

g:Graphics2D: The Graphics2D surface to paint to
c:JComponent: 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:int: The width of the region to paint. Note that in the case of painting the foreground, this value may differ from c.getWidth().
height:int: The height of the region to paint. Note that in the case of painting the foreground, this value may differ from c.getHeight().

getBorderInsets	back to summary
public Insets getBorderInsets(Component c) Implements javax.swing.border.Border.getBorderInsets. Returns the insets of the border. Parameters c:Component the component for which this border insets value applies

getBorderInsets

public Insets getBorderInsets(Component c)

Implements javax.swing.border.Border.getBorderInsets.

Returns the insets of the border.

Parameters

c:Component: the component for which this border insets value applies

getExtendedCacheKeys	back to summary
protected Object[] getExtendedCacheKeys(JComponent c) Overrides javax.swing.plaf.nimbus.AbstractRegionPainter.getExtendedCacheKeys. Doc from javax.swing.plaf.nimbus.AbstractRegionPainter.getExtendedCacheKeys. 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. Annotations @Override

protected Object[] getExtendedCacheKeys(JComponent c)

getPaintContext	back to summary
protected AbstractRegionPainter.PaintContext getPaintContext() Implements abstract javax.swing.plaf.nimbus.AbstractRegionPainter.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:AbstractRegionPainter.PaintContext a PaintContext associated with this paint operation.

isBorderOpaque	back to summary
public boolean isBorderOpaque() Implements javax.swing.border.Border.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.
