WindowsProgressBarUIpublic class WindowsProgressBarUI extends BasicProgressBarUI Windows rendition of the component.
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. A future release of Swing will provide support for
long term persistence. |
