• update

  public void update(Graphics g,
                     JComponent c)

  Notifies this UI delegate to repaint the specified component. This method paints the component background, then calls the paint(SynthContext,Graphics) method.

  In general, this method does not need to be overridden by subclasses. All Look and Feel rendering code should reside in the paint method.

  Overrides:

  update in class ComponentUI

  Parameters:

  g - the Graphics object used for painting

  c - the component being painted

  See Also:

  paint(SynthContext,Graphics)

• paint

                    JComponent c)

  Paints the specified component according to the Look and Feel.

  This method is not used by Synth Look and Feel. Painting is handled by the paint(SynthContext,Graphics) method.

  Overrides:

  paint in class BasicTableHeaderUI

  Parameters:

  g - the Graphics object used for painting

  c - the component being painted

  See Also:

  paint(SynthContext,Graphics)
