30 \title Event Transitions Example
32 \brief The Event Transitions example shows how to use event transitions, a
33 feature of \l{The State Machine Framework}.
35 \snippet examples/statemachine/eventtransitions/main.cpp 0
37 The \c Window class's constructors begins by creating a button.
39 \snippet examples/statemachine/eventtransitions/main.cpp 1
41 Two states, \c s1 and \c s2, are created; upon entry they will assign
42 "Outside" and "Inside" to the button's text, respectively.
44 \snippet examples/statemachine/eventtransitions/main.cpp 2
46 When the button receives an event of type QEvent::Enter and the state
47 machine is in state \c s1, the machine will transition to state \c s2.

51 When the button receives an event of type QEvent::Leave and the state
52 machine is in state \c s2, the machine will transition back to state \c
55 \snippet examples/statemachine/eventtransitions/main.cpp 4
57 Next, the state \c s3 is created. \c s3 will be entered when the button
58 receives an event of type QEvent::MouseButtonPress and the state machine
59 is in state \c s2. When the button receives an event of type
60 QEvent::MouseButtonRelease and the state machine is in state \c s3, the
61 machine will transition back to state \c s2.
63 \snippet examples/statemachine/eventtransitions/main.cpp 5
65 Finally, the states are added to the machine as top-level states, the
66 initial state is set to be \c s1 ("Outside"), and the machine is started.

70 The main() function constructs a Window object and shows it.
