Re: [Boost-users] statechart - time event...implementation ?

Thanks Andreas,
I was thinking more on the lines of implementing:
1. time_event : sc::event<>

And a scheduler that delays by doing a peak into
Every event ( to see if it has delay set ).
2. delay_scheduler : sc::fifo_scheduler<...

And use the rest of the library un-changed.

Could you advise if this is a workable approach ?

Thank You

Raja

Correct.

You'd probably also need a special type of state, see link below.

Chris seems to have implemented a platform-specific solution (see link below), 
I'm not aware of a general solution.

You mean that many people would need such an event? I agree.

For a rationale, please see at the bottom of the following message:

Yes, unfortunately. At least with the current version.
