[Qt-interest] question about QStateMachine setTargetStates() - how deterministic is it?

[Kent Hansen]

Hi Alan,
It's not a bug, but I've created 
http://bugreports.qt.nokia.com/browse/QTBUG-9842 to make it more clear 
what the meaning of multiple target states is.
You might also want to take a look at http://www.w3.org/TR/scxml/; 
appendix B in particular ("Algorithm for SCXML interpretation"). Oh, and 
appendix C ("Probabilistic State Machines"), which is essentially the 
solution Sean proposed. :-)

Regards,
Kent
