Detailed Description

Widget for displaying a KDSME::StateMachine in a Qt Quick based view.

Simple example building up and display a state machine in a view:

    StateMachine machine;
    State s1(&machine);
    s1.setLabel(QStringLiteral("s1"));
    State s2(&machine);
    s2.setLabel(QStringLiteral("s2"));
    s1.addSignalTransition(&s2);
 
    StateMachineView view;
    view.scene()->setRootState(&machine);
    view.scene()->layout();
    view.resize(800, 600);
    view.show();

Examples: scxmlimport/main.cpp, and simplestatemachine/main.cpp.
