* Reset history states when (re)starting state machineKent Hansen2010-03-221-0/+59

* Export QStateMachine::WrappedEvent and QStateMachine::SignalEventEskil Abrahamsen Blomfeldt2009-11-181-0/+8
| | | | | | | | These two classes were missing exports. Since the accessors are inline, the bug would only be visible when someone tried to call the constructors of the classes. Reviewed-by: Kent Hansen

* Rename QState::polished() signal to "propertiesAssigned"Eskil Abrahamsen Blomfeldt2009-11-031-17/+17
| | | | | | | | | "Polished" was never a very descriptive word, and it already has a meaning attached in the QStyle API. Additionally, "propertiesAssigned" has the benefit of giving the relation to the assignProperty() function as part of the name. Reviewed-by: Kent Hansen
* Remove return type of QState::addTransition(QAbstractTransition*)Eskil Abrahamsen Blomfeldt2009-11-031-14/+28
| | | | | | | | | Returning the input argument in a function can lead to confusion and serves no purpose here. Instead, we'll mirror the API from QMenu::addAction() overloads, where the overload that takes a preconstructed object has a void return type. Reviewed-by: Kent Hansen
* Change name of DoNotRestoreProperties enum to DontRestorePropertiesEskil Abrahamsen Blomfeldt2009-11-031-4/+4
| | | | | | | Using the abbreviated "Dont" is consistent with other negated enum names in Qt. Reviewed-by: Kent Hansen
* Change name of QStateMachine::animationsEnabled property to "animated"Eskil Abrahamsen Blomfeldt2009-11-031-5/+5
| | | | | | | The name "animated" is consistent with naming in Qt otherwise, as in QTreeView::animated and QMainWindow::animated. Reviewed-by: Kent Hansen
* Cache a state's parent stateKent Hansen2009-10-291-0/+9
| | | | | | | | | | | | | QAbstractState::parentState() is called heavily by the state machine algorithm. The parent state is obtained by qobject_cast'ing QObject::parent(). qobject_cast() is expensive. This commit introduces caching of the result in order to improve performance. We expect that the cache won't be invalidated much since the parent-child relationship of states usually doesn't change after the state machine is started. Reviewed-by: Eskil Abrahamsen Blomfeldt
* Make QStateMachine event posting functions thread-safeKent Hansen2009-10-291-0/+48
| | | | | | | | By popular demand on the Qt Labs blog. This makes it possible to readily use QStateMachine with e.g. worker threads that post events to the machine. Reviewed-by: Eskil Abrahamsen Blomfeldt
* Test that we gracefully handle event posting after the state machine is stoppedKent Hansen2009-10-291-0/+17
| | | | | The internal slot _q_process() should never be called if the machine is not in the Running state.
* statemachine: implement cloning of a whole bunch more GUI eventsKent Hansen2009-10-061-0/+27
| | | | | Now using QEventTransition with almost any type of event will actually work, instead of causing an assert.
* Make sure delayed events are cancelled when a state machine haltsKent Hansen2009-09-291-0/+39
| | | | | | | Otherwise the events might creep into the event loop if the state machine is restarted. Reviewed-by: Eskil Abrahamsen Blomfeldt
* Introduce state machine event priority, make it possible to cancel eventsKent Hansen2009-09-291-5/+44
| | | | | | | | | | | | The priority specifies whether the event should be posted to what the SCXML spec refers to as the "external" (NormalPriority) queue, or the "internal" (HighPriority) queue. Delayed events are now posted through a separate function, postDelayedEvent(). That function returns an id that can be passed to cancelDelayedEvent() to cancel it.

* Do synchronous processing of events in state machine if possibleKent Hansen2009-09-291-0/+33
| | | | | | | | Avoid delayed scheduling in the cases where there's no need to delay it (e.g. when the state machine intercepts a signal or event). Task-number: QTBUG-4491 Reviewed-by: Eskil Abrahamsen Blomfeldt
* add a test for custom QEventTransitionKent Hansen2009-09-281-3/+74
| | | | | Test that the event has the right attributes. Also improve the custom QSignalTransition test to cover all attributes.
* Make QSignalEvent and QWrappedEvent inner classes of QStateMachineKent Hansen2009-09-281-2/+2
| | | | | | | | | Those two classes are specific to the state machine framework, but their names were so generic that we felt they were polluting the Q-namespace. They are now QStateMachine::SignalEvent and QStateMachine::WrappedEvent. Reviewed-by: Eskil Abrahamsen Blomfeldt

* Q_ASSERT failure in QStateMachinePrivate::handleTransitionSignal.Gabriel de Dietrich2009-08-281-0/+42
| | | | | | | | | | | | | | The signal index actually emitted was different from the signal index registered. This was due to recent changes in the meta-object protocol, where new indexes are being created (cloned) for signals with default parameters. When registering the transition signal, we now look for the original (non cloned) signal index. The transition keeps track of the user-specified signal index, and sets it when calling onTransition.

* | remove constructors that are not usefulKent Hansen2009-08-031-17/+13
| | | | | | | | | | | | | | The constructors that take a list of target states produce hard-to-read code, and they're rarely useful in practice since 99% of transitions take a single target state; so it's better to enforce that setTarget{State,States}() be used instead.
* | add private goToState() function to state machineKent Hansen2009-07-311-0/+41
| | | | | | | | Needed for Declarative UI integration.
* | Make QStateMachine inherit QStateKent Hansen2009-07-221-234/+277
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes the need for a "root state" in the machine; or rather, the machine _is_ the root state. User code can now pass in a QStateMachine directly to the QState constructor, instead of machine->rootState(). This also means we could get rid of the "proxying" from the machine to the root state for things like properties (initialState et al), finished() signal and auto-reparenting of states (the ChildAdded event hack). A fun little side-effect of this change is that it's now possible to embed state machines within state machines. We can't think of a good use case yet where you would rather embed a stand-alone state machine (with its own event processing etc.) rather than having just a regular nested state, but it's neat and it works.

* | Disable private unit tests when Qt is configured withoutRohan McGovern2009-07-091-0/+2
|/ | | | | | | | | | | | -developer-build, part 2. Some autotests use private (unexported) code, either because they're testing private classes or because that's the easiest way to test the public classes. Configuring Qt with `-developer-build' is needed for these tests. This commit fixes the tests so configuring without `-developer-build' only builds the tests which strictly use public API.
* Remove default error stateEskil Abrahamsen Blomfeldt2009-06-231-38/+48
| | | | | | | | | Having an implicit default error state in the graph which the user has not added is unintuitive and ugly. Rather than have a default error state, we stop execution of the machine and print an error message when the machine has run-time errors. If a user wishes to prevent errors from stopping the machine, you can set one or more error states explicitly.
