Gambas structures are really Gambas objects, except that they can be embedded inside other objects or structures (you cannot embed a Gambas object inside another one). Beside that special behaviour (and two other ones in extern function management and stream management), Gambas makes no difference between a structure object and a normal object. And I have never tested inheritance and structure... Maybe not a good idea. :-) Otherwise, to get the real details, you have to read the interpreter source code! :-) Regards, -- Benoît Minisini ------------------------------------------------------------------------------ Keep Your Developer Skills Current with LearnDevNow!
