Detailed Description

The QState class provides a general-purpose state for QStateMachine.

QState objects can have child states, and can have transitions to other states. QState is part of The State Machine Framework.

The addTransition() function adds a transition. The removeTransition() function removes a transition. The transitions() function returns the state's outgoing transitions.

The assignProperty() function is used for defining property assignments that should be performed when a state is entered.

Top-level states must be passed a QStateMachine object as their parent state, or added to a state machine using QStateMachine::addState().

States with Child States

The childMode property determines how child states are treated. For non-parallel state groups, the setInitialState() function must be called 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 QState::finished() signal when a final child state (QFinalState) is entered.

The setErrorState() 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).

Member Enumeration Documentation

This enum specifies how a state's child states are treated.

Enumerator
ExclusiveStates 

The child states are mutually exclusive and an initial state must be set by calling QState::setInitialState().

ParallelStates 

The child states are parallel. When the parent state is entered, all its child states are entered in parallel.

Constructor & Destructor Documentation

QtCore.QState.QState ( System.Type  dummy)
protected
QtCore.QState.QState ( QState  parent = null)

Constructs a new state with the given parent state.

Here is the call graph for this function:

QtCore.QState.QState ( QState.ChildMode  childMode,
QState  parent = null 
)

Constructs a new state with the given childMode and the given parent state.

Here is the call graph for this function:

Member Function Documentation

new void QtCore.QState.AddTransition ( QAbstractTransition  transition)

Adds the given transition. The transition has this state as the source. This state takes ownership of the transition.

new QAbstractTransition QtCore.QState.AddTransition ( QAbstractState  target)

Adds an unconditional transition from this state to the given target state, and returns then new transition object.

new QSignalTransition QtCore.QState.AddTransition ( QObject  sender,
string  signal,
QAbstractState  target 
)

Adds a transition associated with the given signal of the given sender object, and returns the new QSignalTransition object. The transition has this state as the source, and the given target as the target state.

new void QtCore.QState.AssignProperty ( QObject object,
string  name,
object  value 
)

Instructs this state to set the property with the given name of the given object to the given value when the state is entered.

See also propertiesAssigned().

protectedvirtual

Reimplemented from QAbstractState::onExit().

Implements QtCore.QAbstractState.

Reimplemented in QtCore.QStateMachine.

new void QtCore.QState.OnFinished ( )
protected

This signal is emitted when a final child state of this state is entered.

See also QFinalState.

new void QtCore.QState.OnPropertiesAssigned ( )
protected

This signal is emitted when all properties have been assigned their final value. If the state assigns a value to one or more properties for which an animation exists (either set on the transition or as a default animation on the state machine), then the signal will not be emitted until all such animations have finished playing.

If there are no relevant animations, or no property assignments defined for the state, then the signal will be emitted immediately before the state is entered.

See also QState::assignProperty() and QAbstractTransition::addAnimation().

new void QtCore.QState.RemoveTransition ( QAbstractTransition  transition)

Removes the given transition from this state. The state releases ownership of the transition.

Property Documentation

new ChildMode QtCore.QState.childMode
getset

This property holds the child mode of this state.

The default value of this property is QState::ExclusiveStates.

new IQStateSignals QtCore.QState.Emit
getprotected
new QAbstractState QtCore.QState.ErrorState
getset

This property holds the error state of this state.

Slot QtCore.QState.Finished
addremove

This signal is emitted when a final child state of this state is entered.

See also QFinalState.

new QAbstractState QtCore.QState.InitialState
getset

This property holds the initial state of this state (one of its child states).

Slot QtCore.QState.PropertiesAssigned
addremove

This signal is emitted when all properties have been assigned their final value. If the state assigns a value to one or more properties for which an animation exists (either set on the transition or as a default animation on the state machine), then the signal will not be emitted until all such animations have finished playing.

If there are no relevant animations, or no property assignments defined for the state, then the signal will be emitted immediately before the state is entered.

See also QState::assignProperty() and QAbstractTransition::addAnimation().

new QMetaObject QtCore.QState.StaticMetaObject
staticget
System.Collections.Generic.List<QAbstractTransition> QtCore.QState.Transitions
get

Returns this state's outgoing transitions (i.e. transitions where this state is the source state), or an empty list if this state has no outgoing transitions.

This function was introduced in Qt 4.7.

See also addTransition().
