The Qt SCXML module provides functionality to create state machines from SCXML files. This includes both dynamically creating state machines (loading the SCXML file and instantiating states and transitions) and generating a C++ file that has a class implementing the state machine. It also contains functionality to support data models and executable content.
To import the QML types into your application, use the following import statement in your .qml file:
