When either state is entered, the text of the button will be set accordingly. \snippet examples/statemachine/twowaybutton/main.cpp 2 When the state machine is in the \c off state and the button is clicked, it will transition to the \c on state; when the state machine is in the \c on state and the button is clicked, it will transition to the \c off state. \snippet examples/statemachine/twowaybutton/main.cpp 3 The states are added to the state machine; they become top-level (sibling) states. \snippet examples/statemachine/twowaybutton/main.cpp 4 The initial state is \c off; this is the state the state machine will immediately transition to once the state machine is started. \snippet examples/statemachine/twowaybutton/main.cpp 5 Finally, the button is resized and made visible, and the application event loop is entered. */
