I have been researching the Boost archives, Tutorials, examples and I do find references to the fact that it is possible to provide arguments along with Events that a custom_reaction (in self-transition) can selectively "react" on based on the value of the argument but I am unable to articulate it using the Boost Statechart library.

I just realized that there is not a single example on how to pass arguments with events. It's very easy to do, though: struct EvWhatever : sc::event< EvWhatever > { int Arg1; double Arg2; // More arguments here }; You might want to add a constructor that accepts corresponding arguments and sets the data members Arg1 & Arg2 accordingly. You can access Arg1 & Arg2 in the react member function, in a transition action or the function called by an in_state_reaction. Hope this helps. if not, please let me know. Regards, -- Andreas Huber
