setRenderingPrototype</H3>
<PRE>
public void <B>setRenderingPrototype</B>(java.lang.Object&nbsp;renderingPrototype)</PRE>
<DL>
<DD>The rendering prototype is optionally used in calculating the size of the 
 List and is recommended for performance reasons. You should invoke it with an object
 representing a theoretical value in the list which will be used to calculate
 the size required for each element in the list.
 <p>This allows list size calculations to work across look and feels and allows
 developers to predetermin size for list elements. 
 <p>e.g. For a list of Strings which you would like to always be 5 characters wide
 you can use a prototype "XXXXX" which would use the preferred size of the XXXXX 
 String to determin the size of the list element. E.g. for a list of dates you can use
 new Date(30, 12, 00) etc..
