<A NAME="getUnitIncrement(int)"><!-- --></A><H3>
getUnitIncrement</H3>
<PRE>
public int <B>getUnitIncrement</B>(int&nbsp;direction)</PRE>
<DL>
<DD>Returns the amount to change the scrollbar's value by,
 given a unit up/down request.  A ScrollBarUI implementation
 typically calls this method when the user clicks on a scrollbar 
 up/down arrow and uses the result to update the scrollbar's
 value.   Subclasses my override this method to compute
 a value, e.g. the change required to scroll up or down one
 (variable height) line text or one row in a table.
 <p>
 The JScrollPane component creates scrollbars (by default) 
 that override this method and delegate to the viewports
 Scrollable view, if it has one.  The Scrollable interface
 provides a more specialized version of this method.<DD><DL>
