[Qt-interest] Going 'back' in a state machine?

[Stephen Kelly]

Hi,

I have a state machine which I transition through, and I have the 
requirement that it must be possible to 'go back' through states. I thought 
about using QHistoryState for that, but I don't think it's meant for that 
because it only records transitions the state when a parent is left, so when 
I transition between siblings, the QHistoryState doesn't bring me anything.

Has anyone else solved this problem already? I'm thinking I probably need to 
implement QAbstractState to do some magic.

All the best,

Steve.
