\title Qt SCXML Invoke Example (Static)
\ingroup examples-qtscxml
\brief Invokes a compiled nested state machine.
\image invoke-static.png
\e{Invoke Example (Static)} demonstrates how to use the \c <invoke> element
with generated nested state-machines, where the SCXML file is compiled to
a C++ class. 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 enable-qt-mode
\printuntil
\section1 Compiling the State Machine
We link against the Qt SCXML module by adding the following line to the
\e invoke-static.pro file:
\quotefromfile invoke-static/invoke-static.pro
\skipto QT
\printline scxml
We then specify the state machine to compile:
\skipto STATECHARTS
\printline statemachine
The Qt SCXML Compiler, \c qscxmlc, is run automatically to generate
\e statemachine.h and \e statemachine.cpp, and to add them to the \c HEADERS
and \c SOURCES variables for compilation.
\section1 Instantiating the State Machine
We instantiate the generated \c Directions class in the \e invoke-static.cpp
file, as follows:
\quotefromfile invoke-static/invoke-static.cpp
\skipto statemachine.h
\printuntil }
