MetalSliderUIpublic class MetalSliderUI extends BasicSliderUI A Java L&F implementation of SliderUI.
Warning:
Serialized objects of this class will not be compatible with
future Swing releases. The current serialization support is
appropriate for short term storage or RMI between applications running
the same version of Swing. As of 1.4, support for long term storage
of all JavaBeansTM
has been added to the java.beans package.
