protected void doPaint(Graphics2D g, JComponent c, int width, int height, Object[] extendedCacheKeys) Implements abstract javax.swing.plaf.nimbus.AbstractRegionPainter.doPaint. Doc from 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. Annotations @Override

getPaintContext	back to summary
protected final AbstractRegionPainter.PaintContext getPaintContext() Implements abstract javax.swing.plaf.nimbus.AbstractRegionPainter.getPaintContext. Doc from 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. Annotations @Override
