I am missing a list of transitions in QState API. 🙁

It is possible to get start-state and target-state from QAbstractTransition, I wonder, why is there no possibility for obtaining the list of transitions leading from one state to another – the state internally knows its transitions anyway.

Obtaining transition list from state would give a possibility for reverse engineering Qt4 FSMs e.g. using graphviz.

P.S.: Are transitions children of QState object? Could they be safely obtained via children list?

Regards.

    If it is possible for you, you could switch to Qt 4.7. They introduced a QState::transitions() method then, http://doc.troll.no/4.7/qstate.html#transitions
