  - 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)
  - paintBorder
```
public void paintBorder(SynthContext context,
               Graphics g,

```
    Description copied from interface: SynthUI
    
    Paints the border.
    
    Specified by:

```
public void paint(Graphics g,
         JComponent c)
```
    Paints the specified component according to the Look and Feel.

    Overrides:
    
    paint in class BasicTreeUI
    
    Parameters:
    g - the Graphics object used for painting
