<DL>
<DD>Returns the model's current value.  Note that the upper

<A NAME="setValue(int)"><!-- --></A><H3>
setValue</H3>
<PRE>
public void <B>setValue</B>(int&nbsp;newValue)</PRE>
<DL>
<DD>Sets the model's current value to <code>newValue</code> if <code>newValue</code>
 satisfies the model's constraints. Those constraints are:
 <pre>
 minimum <= value <= value+extent <= maximum
 </pre>
 Otherwise, if <code>newValue</code> is less than <code>minimum</code> 
 it's set to <code>minimum</code>, if its greater than 
 <code>maximum</code> then it's set to <code>maximum</code>, and 
 if it's greater than <code>value+extent</code> then it's set to 
 <code>value+extent</code>.
 <p>
 When a BoundedRange model is used with a scrollbar the value
 specifies the origin of the scrollbar knob (aka the "thumb" or
 "elevator").  The value usually represents the origin of the 
 visible part of the object being scrolled.
 <p>
 Notifies any listeners if the model changes.<DD><DL>

<A NAME="setValueIsAdjusting(boolean)"><!-- --></A><H3>
setValueIsAdjusting</H3>
<PRE>
public void <B>setValueIsAdjusting</B>(boolean&nbsp;b)</PRE>
<DL>
<DD>This attribute indicates that any upcoming changes to the value
 of the model should be considered a single event. This attribute
 will be set to true at the start of a series of changes to the value,
 and will be set to false when the value has finished changing.  Normally
 this allows a listener to only take action when the final value change in
 committed, instead of having to do updates for all intermediate values.
 <p>
 Sliders and scrollbars use this property when a drag is underway.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>b</CODE> - true if the upcoming changes to the value property are part of a series</DL>
</DD>
</DL>

<A NAME="getValueIsAdjusting()"><!-- --></A><H3>

<A NAME="getExtent()"><!-- --></A><H3>
getExtent</H3>
<PRE>
public int <B>getExtent</B>()</PRE>
<DL>
<DD>Returns the model's extent, the length of the inner range that
 begins at the model's value.<DD><DL>
<DT><B>Returns:</B><DD>the value of the model's extent property<DT><B>See Also: </B><DD><A HREF="../../javax/swing/BoundedRangeModel.html#setExtent(int)"><CODE>setExtent(int)</CODE></A>,

<HR>

<A NAME="setExtent(int)"><!-- --></A><H3>
setExtent</H3>
<PRE>
public void <B>setExtent</B>(int&nbsp;newExtent)</PRE>
<DL>
<DD>Sets the model's extent.  The <I>newExtent</I> is forced to 
 be greater than or equal to zero and less than or equal to
 maximum - value.   
 <p>
 When a BoundedRange model is used with a scrollbar the extent
 defines the length of the scrollbar knob (aka the "thumb" or
 "elevator").  The extent usually represents how much of the 
 object being scrolled is visible. When used with a slider,
 the extent determines how much the value can "jump", for
 example when the user presses PgUp or PgDn.
 <p>
 Notifies any listeners if the model changes.<DD><DL>

<DL>
<DD>This method sets all of the model's data with a single method call.
 The method results in a single change event being generated. This is
 convenient when you need to adjust all the model data simulaneously and
 do not want individual change events to occur.<DD><DL>
