JSVGCanvas displayed gvt components, editing and then saving.

[Roger I Martin PhD]

Hi,   I've learned to add, remove, modify the JSVGCanvas displayed svg DOM, save it back to a file with the changes.  Also learned how to modify a gvt component on the canvas with user keyboard and mouse interaction (i.e. mouseDragged(org.apache.batik.gvt.event.GraphicsNodeMouseEvent evt);).  What I don't have is how to "bridge" the results of the gvt modifications back to the DOM and subsequently save the results back to an svg doc.  After the change is back in the DOM I could then save it.  Anybody have a hint to how it can be done?   --Roger
