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

    \brief Invokes a dynamically loaded nested state machine.

    \image invoke-dynamic.png

    \e{Invoke Example (Dynamic)} demonstrates how to use the \c <invoke> element
    with generated nested state-machines, where the SCXML file is dynamically
    loaded. The \c <invoke> element is used to create an instance of an external
    service.

    \include examples-run.qdocinc

    \section1 Invoking the State Machine

    In \e statemachine.scxml, we specify a state machine with the name
    \e Directions of type \e http://www.w3.org/TR/scxml/ to invoke:

    \quotefromfile invoke-common/statemachine.scxml
    \skipto scxml
    \printuntil

    \section1 Dynamically Loading the State Machine

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

    \quotefromfile invoke-dynamic/invoke-dynamic.pro
    \skipto QT
    \printline scxml

    We dynamically create the state machine, as follows:

    \quotefromfile invoke-dynamic/invoke-dynamic.qml
    \skipto import
    \printuntil }
