Hi Manuel

I would really like to use a priority_scheduler<> in the statechart library. It is on the todo list of boost 1.34.1. How about its development status? Is it in development

No, and it's unlikely that I'll get to it it in time for 1.36 (unless of course I'll get more requests for it, yours was the first one).

or hast someone his own homebrew solution for a finite state machine with a priority scheduled event dispatcher?

I guess some Statechart users must have rolled their own priority_scheduler, but I haven't heard about them.

At the moment i'm using the nice ordered Multi_Index_Container to implement a priority queue. Ideas?

Implementing a priority_scheduler should not be difficult. You'll find some information about the responsibilities of the fifo_scheduler components here: <http://www.boost.org/libs/statechart/doc/rationale.html#AsynchronousStateMachines>, see Customization HTH & Regards, -- Andreas Huber When replying by private email, please remove the words spam and trap from the address shown in the header.
