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.
update in class ComponentUIg - the Graphics object used for paintingc - the component being paintedpaint(SynthContext,Graphics)public void paint(Graphics g, JComponent c)
This method is not used by Synth Look and Feel.
Painting is handled by the paint(SynthContext,Graphics) method.

increment/decrement buttons,
and the minimum width of the thumb. The preferred height is the
sum of the preferred heights of the same parts. The basis for
the preferred size of a horizontal scrollbar is similar.
The preferredSize is only computed once, subsequent
calls to this method just return a cached size.

Warning : the value returned by this method should not be be modified, it's a shared static constant.
