Detailed Description

State objects can have child states as well as transitions to other states. State is part of The Declarative State Machine Framework.

States with Child States

The childMode property determines how child states are treated. For non-parallel state groups, the initialState property must be used to set the initial state. The child states are mutually exclusive states, and the state machine needs to know which child state to enter when the parent state is the target of a transition.

The state emits the State::finished() signal when a final child state (FinalState) is entered.

The errorState sets the state's error state. The error state is the state that the state machine will transition to if an error is detected when attempting to enter the state (e.g. because no initial state has been set).

Example Usage

 import QtQuick 2.0
 import QtQml.StateMachine 1.0 as DSM

 Rectangle {
     DSM.StateMachine {
         id: stateMachine
         initialState: state
         running: true
         DSM.State {
             id: state
         }
     }
 }
