<A NAME="setValue(java.lang.Object)"><!-- --></A><H3>
setValue</H3>
<PRE>
public void <B>setValue</B>(<A HREF="../../java/lang/Object.html">Object</A>&nbsp;value)</PRE>
<DL>
<DD>Set (or change) the object that is to be edited.  Primitive types such
 as "int" must be wrapped as the corresponding object type such as
 "java.lang.Integer".<DD><DL>
<DT><B>Parameters:</B><DD><CODE>value</CODE> - The new target object to be edited.  Note that this
     object should not be modified by the PropertyEditor, rather 
     the PropertyEditor should create a new object to hold any
     modified value.</DL>
</DD>
</DL>
<HR>

<A NAME="getValue()"><!-- --></A><H3>
getValue</H3>
<PRE>
public <A HREF="../../java/lang/Object.html">Object</A> <B>getValue</B>()</PRE>
<DL>
<DD>Gets the property value.<DD><DL>
<DT><B>Returns:</B><DD>The value of the property.  Primitive types such as "int" will
 be wrapped as the corresponding object type such as "java.lang.Integer".</DL>
</DD>
</DL>
<HR>

<A NAME="isPaintable()"><!-- --></A><H3>
isPaintable</H3>
<PRE>
public boolean <B>isPaintable</B>()</PRE>
<DL>
<DD>Determines whether this property editor is paintable.<DD><DL>
<DT><B>Returns:</B><DD>True if the class will honor the paintValue method.</DL>
</DD>
</DL>
<HR>

<A NAME="paintValue(java.awt.Graphics, java.awt.Rectangle)"><!-- --></A><H3>
paintValue</H3>
<PRE>
public void <B>paintValue</B>(<A HREF="../../java/awt/Graphics.html">Graphics</A>&nbsp;gfx,
                       <A HREF="../../java/awt/Rectangle.html">Rectangle</A>&nbsp;box)</PRE>
<DL>
<DD>Paint a representation of the value into a given area of screen
 real estate.  Note that the propertyEditor is responsible for doing
 its own clipping so that it fits into the given rectangle.
 <p>
 If the PropertyEditor doesn't honor paint requests (see isPaintable)
 this method should be a silent noop.
 <p>
 The given Graphics object will have the default font, color, etc of
 the parent container.  The PropertyEditor may change graphics attributes
 such as font and color and doesn't need to restore the old values.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>gfx</CODE> - Graphics object to paint into.<DD><CODE>box</CODE> - Rectangle within graphics object into which we should paint.</DL>
</DD>
</DL>
<HR>

<A NAME="getJavaInitializationString()"><!-- --></A><H3>
getJavaInitializationString</H3>
<PRE>
public <A HREF="../../java/lang/String.html">String</A> <B>getJavaInitializationString</B>()</PRE>
<DL>
<DD>This method is intended for use when generating Java code to set
 the value of the property.  It should return a fragment of Java code
 that can be used to initialize a variable with the current property
 value.
 <p>
 Example results are "2", "new Color(127,127,34)", "Color.orange", etc.<DD><DL>
<DT><B>Returns:</B><DD>A fragment of Java code representing an initializer for the
   	current value.</DL>
</DD>
</DL>
<HR>

<A NAME="getAsText()"><!-- --></A><H3>
getAsText</H3>
<PRE>
public <A HREF="../../java/lang/String.html">String</A> <B>getAsText</B>()</PRE>
<DL>
<DD>Gets the property value as text.<DD><DL>
<DT><B>Returns:</B><DD>The property value as a human editable string.
 <p>   Returns null if the value can't be expressed as an editable string.
 <p>   If a non-null value is returned, then the PropertyEditor should
	     be prepared to parse that string back in setAsText().</DL>
</DD>
</DL>
<HR>

<A NAME="setAsText(java.lang.String)"><!-- --></A><H3>
setAsText</H3>
<PRE>
public void <B>setAsText</B>(<A HREF="../../java/lang/String.html">String</A>&nbsp;text)
               throws <A HREF="../../java/lang/IllegalArgumentException.html">IllegalArgumentException</A></PRE>
<DL>
<DD>Set the property value by parsing a given String.  May raise
 java.lang.IllegalArgumentException if either the String is
 badly formatted or if this kind of property can't be expressed
 as text.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>text</CODE> - The string to be parsed.</DL>
</DD>
</DL>
<HR>

<A NAME="getTags()"><!-- --></A><H3>
getTags</H3>
<PRE>
public <A HREF="../../java/lang/String.html">String</A>[] <B>getTags</B>()</PRE>
<DL>
<DD>If the property value must be one of a set of known tagged values, 
 then this method should return an array of the tags.  This can
 be used to represent (for example) enum values.  If a PropertyEditor
 supports tags, then it should support the use of setAsText with
 a tag value as a way of setting the value and the use of getAsText
 to identify the current value.<DD><DL>
<DT><B>Returns:</B><DD>The tag values for this property.  May be null if this 
   property cannot be represented as a tagged value.</DL>
</DD>
</DL>
<HR>

<A NAME="getCustomEditor()"><!-- --></A><H3>
getCustomEditor</H3>
<PRE>
public <A HREF="../../java/awt/Component.html">Component</A> <B>getCustomEditor</B>()</PRE>
<DL>
<DD>A PropertyEditor may choose to make available a full custom Component
 that edits its property value.  It is the responsibility of the
 PropertyEditor to hook itself up to its editor Component itself and
 to report property value changes by firing a PropertyChange event.
 <P>
 The higher-level code that calls getCustomEditor may either embed
 the Component in some larger property sheet, or it may put it in
 its own individual dialog, or ...<DD><DL>
<DT><B>Returns:</B><DD>A java.awt.Component that will allow a human to directly
      edit the current property value.  May be null if this is
	    not supported.</DL>
</DD>
</DL>
<HR>

<A NAME="supportsCustomEditor()"><!-- --></A><H3>
supportsCustomEditor</H3>
<PRE>
public boolean <B>supportsCustomEditor</B>()</PRE>
<DL>
<DD>Determines whether this property editor supports a custom editor.<DD><DL>
<DT><B>Returns:</B><DD>True if the propertyEditor can provide a custom editor.</DL>
</DD>
</DL>
<HR>

<A NAME="addPropertyChangeListener(java.beans.PropertyChangeListener)"><!-- --></A><H3>
addPropertyChangeListener</H3>
<PRE>
public void <B>addPropertyChangeListener</B>(<A HREF="../../java/beans/PropertyChangeListener.html">PropertyChangeListener</A>&nbsp;listener)</PRE>
<DL>
<DD>Register a listener for the PropertyChange event.  When a
 PropertyEditor changes its value it should fire a PropertyChange
 event on all registered PropertyChangeListeners, specifying the
 null value for the property name and itself as the source.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>listener</CODE> - An object to be invoked when a PropertyChange
		event is fired.</DL>
</DD>
</DL>
<HR>

<A NAME="removePropertyChangeListener(java.beans.PropertyChangeListener)"><!-- --></A><H3>
removePropertyChangeListener</H3>
<PRE>
public void <B>removePropertyChangeListener</B>(<A HREF="../../java/beans/PropertyChangeListener.html">PropertyChangeListener</A>&nbsp;listener)</PRE>
<DL>
<DD>Remove a listener for the PropertyChange event.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>listener</CODE> - The PropertyChange listener to be removed.</DL>
