- \enum QAbstractState::RestorePolicy
-
- This enum specifies the restore policy type for a state. The restore policy
- takes effect when the machine enters a state which sets one or more
- properties. If the restore policy of the state is set to RestoreProperties,
- the state machine will save the original value of the property before the
- new value is set.
-
- Later, when the machine either enters a state which has its restore policy
- set to DoNotRestoreProperties or when it enters a state which does not set
- a value for the given property, the property will automatically be restored
- to its initial value.
-
- Only one initial value will be saved for any given property. If a value for a property has
- already been saved by the state machine, it will not be overwritten until the property has been
- successfully restored. Once the property has been restored, the state machine will clear the
- initial value until it enters a new state which sets the property and which has RestoreProperties
- as its restore policy.
-
- \value GlobalRestorePolicy The restore policy for the state should be retrieved using
- QStateMachine::globalRestorePolicy()
- \value DoNotRestoreProperties The state machine should not save the initial values of properties
- set in the state and restore them later.
- \value RestoreProperties The state machine should save the initial values of properties
- set in the state and restore them later.
