Hello, Is it possible to delay the handling of an event?

If I've three states X, Y and Z; initial state is X. State Y is entered if X receives event y1. State Z is entered if X receives event z1. X is entered if Y receives event y2. Y is entered if Z receives event z2.

If Y is entered then it executes a function which will generate event y2 during ist processing (function will be executed in another thread - thread passes event y2 to state machine). It is possible that event z1 is passed to the state machine before event y2.

How can I delay processing of event z1 until y2 event handling has taken place?

How about adding a z1 deferral reaction to Y, see <http://www.boost-consulting.com/boost/libs/statechart/doc/tutorial.html#DeferringEvents>? Regards, -- Andreas Huber When replying by private email, please remove the words spam and trap from the address shown in the header.
