o updateUI 
public void updateUI()
Notification from the UIFactory that the L&F has changed.

Overrides:
updateUI in class JComponent
o getUIClassID 
public String getUIClassID()
Returns:
"ScrollBarUI"
Overrides:

o setValues 
public void setValues(int newValue,
                      int newExtent,
                      int newMinimum,
                      int newMaximum)
Ensures that the model is always in a consistent state by enforcing the following constraints. 
   minimum < maximum
   minimum <= value
   extent >= 1
   value <= maximum - extent
If neccessary we change newValue and newExtent, newExtent is forced to be greater than 0.
