+    \title Event Transitions Example
+
+    The Event Transitions example shows how to use event transitions, a
+    feature of \l{The State Machine Framework}.
+
+    \snippet statemachine/eventtransitions/main.cpp 0
+
+    The \c Window class's constructors begins by creating a button.
+
+    \snippet statemachine/eventtransitions/main.cpp 1
+
+    Two states, \c s1 and \c s2, are created; upon entry they will assign
+    "Outside" and "Inside" to the button's text, respectively.
+
+    \snippet statemachine/eventtransitions/main.cpp 2
+
+    When the button receives an event of type QEvent::Enter and the state
+    machine is in state \c s1, the machine will transition to state \c s2.
+
+    \snippet statemachine/eventtransitions/main.cpp 3
+
+    When the button receives an event of type QEvent::Leave and the state
+    machine is in state \c s2, the machine will transition back to state \c
+    s1.
+
+    \snippet statemachine/eventtransitions/main.cpp 4
+
+    Next, the state \c s3 is created. \c s3 will be entered when the button
+    receives an event of type QEvent::MouseButtonPress and the state machine
+    is in state \c s2. When the button receives an event of type
+    QEvent::MouseButtonRelease and the state machine is in state \c s3, the
+    machine will transition back to state \c s2.
+
+    \snippet statemachine/eventtransitions/main.cpp 5
+
+    Finally, the states are added to the machine as top-level states, the
+    initial state is set to be \c s1 ("Outside"), and the machine is started.
+
+    \snippet statemachine/eventtransitions/main.cpp 6
+
+    The main() function constructs a Window object and shows it.
