setCellRenderer() for a JTree

Hi,

I use SwiXML with the FormLayout Patch
(http://jroller.com/page/ozeebee/20041224) and SwiXAT.

I need a way to set the cellRender or cellEditor via XML for a JTree. Has
anybody such a patch for SwiXML?

If not, I will try to write such a patch. Any tips?

example SwiXML/SwiXAT XML:
<tree id="unitTree" origin="$UNITS/rootUnits" iterate="true"> 
        <cellRenderer class="my.own.CellRendererClass"/> 
</tree> 

regards,
Joachim
