What do you mean by re-connect?  You can create (programatically) a 
new connection and remove the old one. Will this work?  As for modify 
the text, I assume you mean through an edit (not progrmatically).  No, 
this cannot be done.  I don't want to add too much editing 
functionality because this is the purpose of GEF.  However, I could 
imagine using a cell editor (like a table or tree) for this purpose. 
 If you would like to open a bug and help with a patch, we could 
probably do this.
As for sub-graphs, see GraphContainer.

    Hi all ,
    I want to get more informations about Zest and I'd like to ask some
    questions via maillist.
    1.Can do "re-connect" operation?
    2.Can modify the label text of nodes directly(on the graphical
    viewer)?
    3.Is there any "sub-graph" stuff (maybe peoples want to display sub
    graph in a "GraphNode") ?
