extends JComponent

implements SwingConstants, Accessible

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 Swing1.0 applications. It will not be possible to load serialized Swing1.0 objects with future releases of Swing. The JDK1.2 release of Swing will be the compatibility baseline for the serialized form of Swing objects.

EventListenerList

 public BoundedRangeModel getModel()

Returns the data model used by the JProgressBar.

Returns:

the BoundedRangeModel currently in use

See Also:

BoundedRangeModel

 public void setModel(BoundedRangeModel newModel)

Sets the data model used by the JProgressBar.

Parameters:

newModel - the BoundedRangeModel to use

See Also:

BoundedRangeModel
