State objects can have child states as well as transitions to other states. State is part of Qt State Machine QML API
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).
import QtQuick import QtQml.StateMachine as DSM Rectangle { DSM.StateMachine { id: stateMachine initialState: state running: true DSM.State { id: state } } }
See also StateMachine and FinalState.
childMode : enumeration
The child mode of this state
The default value of this property is QState.ExclusiveStates.
This enum specifies how a state's child states are treated:
errorState : QAbstractState
The error state of this state.
initialState : QAbstractState
The initial state of this state (one of its child states).
finished()
This signal is emitted when a final child state of this state is entered.
Note: The corresponding handler is onFinished
.
