Accessing the event when using nextEvents

[<robinson.ged+graphstream AT gmail.com>]

First, thanks for GraphStream.  It's a great library.  just what I was looking
for.

I am reading a DGS file with a FileSource object and the nextEvents() method. 
It works just fine and the graph is produced and rendered.

However after each nextEvents() method call I wouldl ike to get access to the
event which has just been processed.  I want to produce some output in a
LayerRenderer which is based  on the most recent event to occur.

How can I get access in my own code to the graph events as they are processed
by nextEvents() ?

Thanks & Regards,
