Mouse Clicks, JTabbedPanel Displacement and Labels with line breaks

[<mauricio0copo AT gmail.com>]

I'm having some issues with the library, and since it is not well known in the
www (it should be! Graphstream is great!), I had to post my questions here.

1 - How do I retrieve mouse clicks on the graph? I folowed the tutorial
available on the documentation, but without success. I need to detect which
node has been clicked and project another graph based on information from that
node.

2 - Since I added the graph view on a JTabbedPane I'm having to click above 
the
label of the node (which is centered inside the node) to get it selected and
move it around. Any thoughts?

3 - The labels on my graphs are huge. Is there a way to create line breaks on
the labels?

Oh, and thank you very much for this library! You have no idea how it's
speeding up the work I need to do!
