FinalState QML Type▲

Import Statement: import QtQml.StateMachine 6.4
Since:: Qt 5.4
Inherits:: QAbstractState
Group: FinalState is part of statemachine-qmltypes

Detailed Description▲

A final state is used to communicate that (part of) a StateMachine has finished its work. When a final top-level state is entered, the state machine's finished() signal is emitted. In general, when a final substate (a child of a State) is entered, the parent state's finished() signal is emitted. FinalState is part of Qt State Machine QML API

To use a final state, you create a FinalState object and add a transition to it from another state.

        DSM.State {
