<PRE>
public void <B>setPropertiesFrom</B>(GraphicStyle&nbsp;graphicStyle)</PRE>
<DL>
<DD>Sets the properties of this  from the properties of the specified
 . This method does not copy the listeners neither the implementation
 hints.
 <p>
 This method may fires many <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/beans/PropertyChangeEvent.html" title="class or interface in java.beans">property change events</A>, one for
 every property that changed. But it fires at most one graphic
 style event with the list of all modified properties as an array.

 Subclasses should implement this method as below:

 <blockquote><pre>

             setMyProperty(ms.getMyProperty());
             // etc...
