protected class JScrollPane.ScrollBar extends JScrollBar implements UIResource
JScrollPane creates scrollbars
that are instances
of this class. Scrollbar overrides the
getUnitIncrement and getBlockIncrement
methods so that, if the viewport's view is a Scrollable,
the view is asked to compute these values. Unless
the unit/block increment have been explicitly set.
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 JavaBeans™
has been added to the java.beans package.
Please see XMLEncoder.

int |
getBlockIncrement(int direction) |
Computes the block increment for scrolling if the viewport's
view is a
Scrollable object. |

getUnitIncrement(int direction) |
Computes the unit increment for scrolling if the viewport's
view is a
Scrollable object. |

setBlockIncrement(int blockIncrement) |
Messages super to set the value, and resets the
blockIncrementSet instance variable to true. |
void |
setUnitIncrement(int unitIncrement) |
Messages super to set the value, and resets the
unitIncrementSet instance variable to true. |
