The easiest way is to use the Gist::PrintingInspector.  For this, just  
implement a function

void  print(std::ostream& os) {...}

that outputs the current state to the stream os (look at the examples  
that come with Gecode, like queens.cc).  Then call Gist like this:

Gecode::Gist::PrintingInspector<YourModelClass> pi("Name of your  
model");
YourModelClass* s = new YourModelClass();
Gecode::explore(s, &pi);
delete s;

If you want something more fancy, just write your own inspector.  All  
you have to do is implement the function inspect, which gets the space  
of the node that has been double-clicked.

Cheers,
