You can use an Inspector to do that. Here's an example (it's for
Gecode 3.x, I noticed you were still using 2.x but something similar
will work there, too):
class ReturnSpaceInspector : public Gist::Inspector {
public:
Space* s;
ReturnSpaceInspector(void) : s(NULL) {}
virtual void inspect(const Space& n) {
delete s;
s = n.clone();
}
virtual std::string name(void) { return "ReturnSpaceInspector"; }
~ReturnSpaceInspector(void) { delete s; }
};
This inspector remembers the space of the last double-clicked node.
Note that you have to clone it! After Gist returns, you can then do
whatever you want with the space.
With the next release, you'll be able to easily add several inspectors
and turn them on and off individually. Until then, the
ReturnSpaceInspector could just inherit from Gist::Print so that you
get both the output and the space.
Cheers,
Guido
