It also provides a signal that's emitted whenever the value of \c - x changes. - - \snippet statemachine/factorial/main.cpp 1 - - The FactorialLoopTransition class implements the guard (\c x > 1) and - calculations (\c fac = \c x * \c fac; \c x = \c x - 1) of the factorial - loop. - - \snippet statemachine/factorial/main.cpp 2 - - The FactorialDoneTransition class implements the guard (\c x <= 1) that - terminates the factorial computation. It also prints the final result to - standard output. - - \snippet statemachine/factorial/main.cpp 3 - - The application's main() function first creates the application object, a - Factorial object and a state machine. - - \snippet statemachine/factorial/main.cpp 4 - - The \c compute state is created, and the initial values of \c x and \c fac - are defined. A FactorialLoopTransition object is created and added to the - state. - - \snippet statemachine/factorial/main.cpp 5 - - A final state, \c done, is created, and a FactorialDoneTransition object - is created with \c done as its target state. The transition is then added - to the \c compute state. - - \snippet statemachine/factorial/main.cpp 6 - - The machine's initial state is set to be the \c compute state. We connect - the QStateMachine::finished() signal to the QCoreApplication::quit() slot, - so the application will quit when the state machine's work is - done. Finally, the state machine is started, and the application's event - loop is entered. - - */ |
