    \title Qt SCXML Traffic Light Example (Dynamic)
    \ingroup examples-qtscxml

    \brief A widget-based application that uses a dynamically loaded state
     machine to implement a traffic light.

    \image trafficlight.png

    \e{Traffic Light Example (Dynamic)} demonstrates how to connect to the
    active properties of a state in a dynamically loaded state machine.

    The UI is created using Qt Widgets.

    \include examples-run.qdocinc

    \section1 Dynamically Loading the State Machine

    We link against the Qt SCXML module by adding the following line to the
    example \e .pro file:

    \quotefromfile trafficlight-widgets-dynamic/trafficlight-widgets-dynamic.pro
    \skipto QT
    \printline scxml

    We dynamically create the state machine in
    \e trafficlight-widgets-dynamic.cpp:

    \quotefromfile trafficlight-widgets-dynamic/trafficlight-widgets-dynamic.cpp
    \skipto trafficlight.h
    \printuntil /^ {4}\}/

    And then instantiate it:

    \printuntil /^\}/

    \include trafficlight-state-machine.qdocinc

    We connect to the states as follows:

    \quotefromfile trafficlight-common/trafficlight.cpp
    \skipto connectToState
    \printuntil greenLight
