Detailed Description

The QtStateMachine class provides a hierarchical finite state machine.

The QtStateMachine class provides a hierarchical finite state machine based on Statecharts concepts and notation. QtStateMachine is part of The State Machine Framework.

A state machine manages a set of states (QtAbstractState objects) and transitions (QtAbstractTransition objects) between those states; the states and the transitions collectively define a state graph. Once a state graph has been defined, the state machine can execute it. QtStateMachine's execution algorithm is based on the State Chart XML (SCXML) algorithm.

The QtState class provides a state that you can use to set properties and invoke methods on QObjects when the state is entered or exited. This is typically used in conjunction with signals; the signals determine the flow of the state graph, whereas the states' property assignments and method invocations are the actions.

Use the addState() function to add a state to the state machine; alternatively, pass the machine's rootState() to the state constructor. Use the removeState() function to remove a state from the state machine.

The following snippet shows a state machine that will finish when a button is clicked:

 QPushButton button;
-
- QtStateMachine machine;
- QtState *s1 = new QtState();
- s1->assignProperty(&button, "text", "Click me");
-
- QtFinalState *s2 = new QtFinalState();
- s1->addTransition(&button, SIGNAL(clicked()), s2);
-
- machine.addState(s1);
- machine.addState(s2);
- machine.setInitialState(s1);
- machine.start();

The setInitialState() function sets the state machine's initial state; this state is entered when the state machine is started.

The start() function starts the state machine. The state machine executes asynchronously, i.e. you need to run an event loop in order for it to make progress. The started() signal is emitted when the state machine has entered the initial state.

The state machine processes events and takes transitions until a top-level final state is entered; the state machine then emits the finished() signal.

The stop() function stops the state machine. The stopped() signal is emitted when the state machine has stopped.

The postEvent() function posts an event to the state machine. This is useful when you are using custom events to trigger transitions.

The rootState() function returns the state machine's root state. All top-level states have the root state as their parent.

Member Type Documentation

enum QtStateMachine::Error

This enum type defines errors that can occur in the state machine at run time. When the state machine encounters an unrecoverable error at run time, it will set the error code returned by error(), the error message returned by errorString(), and enter an error state based on the context of the error.

- - - - -
Constant Value Description
QtStateMachine::NoError 0 No error has occurred.
QtStateMachine::NoInitialStateError 1 The machine has entered a QtState with children which does not have an initial state set. The context of this error is the state which is missing an initial state.
QtStateMachine::NoDefaultStateInHistoryState 2 The machine has entered a QtHistoryState which does not have a default state set. The context of this error is the QtHistoryState which is missing a default state.

Member Function Documentation

QtStateMachine::QtStateMachine ( QObject * parent = 0 )

Constructs a new state machine with the given parent.

QtStateMachine::~QtStateMachine ()

Destroys this state machine.

void QtStateMachine::addState ( QtAbstractState * state )

Adds the given state to this state machine. The state becomes a top-level state (i.e. a child of the rootState()).

If the state is already in a different machine, it will first be removed from its old machine, and then added to this machine.

void QtStateMachine::animationsFinished () `[signal]`

This signal is emitted when the state machine has finished playing all animations associated with the latest transition (i.e., all properties have reached their target values).

void QtStateMachine::clearError ()

Clears the error string and error code of the state machine.

Error QtStateMachine::error () const

Returns the error code of the last error that occurred in the state machine.

void QtStateMachine::finished () `[signal]`

This signal is emitted when the state machine has reached a top-level final state.

QtAbstractState::RestorePolicy QtStateMachine::globalRestorePolicy () const

Returns the global restore policy of the state machine.

void QtStateMachine::postEvent ( QEvent * event, int delay = 0 )

Posts the given event for processing by this state machine, with a delay of delay milliseconds.

This function returns immediately. The event is added to the state machine's event queue. Events are processed in the order posted. The state machine takes ownership of the event and deletes it once it has been processed.

You can only post events when the state machine is running.

void QtStateMachine::removeState ( QtAbstractState * state )

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

void QtStateMachine::setGlobalRestorePolicy ( QtAbstractState::RestorePolicy restorePolicy )

Sets the global restore policy of the state machine to restorePolicy. The default global restore policy is QtAbstractState::DoNotRestoreProperties.

The global restore policy cannot be set to QtAbstractState::GlobalRestorePolicy.

void QtStateMachine::start () `[slot]`

Starts this state machine. The machine will reset its configuration and transition to the initial state. When a final top-level state is entered, the machine will emit the finished() signal.

See also started(), finished(), stop(), and initialState().

void QtStateMachine::started () `[signal]`

This signal is emitted when the state machine has entered its initial state.

QList<QtAbstractState *> QtStateMachine::states () const

Returns the list of this state machine's states, or an empty list if the state machine has no states.

void QtStateMachine::stop () `[slot]`

Stops this state machine.

void QtStateMachine::stopped () `[signal]`

This signal is emitted when the state machine has stopped.

Detailed Description

The QtTransition class provides an action-based transition.

QtTransition provides an action-based transition; you add actions with the addAction() function. The transition executes the actions when the transition is triggered. QtTransition is part of The State Machine Framework.

The invokeMethodOnTransition() function is used for defining method invocations that should be performed when a transition is taken.

 QtStateMachine machine;
- QtState *s1 = new QtState();
- machine.addState(s1);
- QtTransition *t1 = new QtTransition();
- QLabel label;
- t1->invokeMethodOnTransition(&label, "clear");
- QtState *s2 = new QtState();
- machine.addState(s2);
- t1->setTargetState(s2);
- s1->addTransition(t1);

Actions are executed in the order in which they were added.

See also QtState::addTransition() and QtStateAction.

Member Function Documentation

The sctools module allows loading SCXML files into a QtScriptedStateMachine object.

The files that the tool can load conform to the State Chart XML (SCXML) standard.

- -

Getting Started with Qt & SCXML

First of all, make yourself familiar with the SCXML specification.
Read this document to understand how to enable SCXML files in your project, and how to load SCXML files in runtime/build-time.
Go over the blackjack, calc and mediaplayer examples for usage demonstration.

- -

Enabling the QtScriptedStateMachine class

The QtScriptedStateMachine class is enabled automatically when the script module is enabled.

- -

Using the QtScriptedStateMachine class

QtScriptedStateMachine is a subclass of QtStateMachine. QtStateMachine actually includes most of the "interesting" API, while QtScriptedStateMachine adds the missing parts to support SCXML.

Most of the interaction with QtScriptedStateMachine occurs after the state-machine is loaded, and before it's started. The interesting functionalities of QtScriptedStateMachine are:

- -

Working with the script engine

The main feature of QtScriptedStateMachine is that it includes a single QScriptEngine object that's shared between all state actions and transitions. That's what allows the states to rely on a single data context for evaluating conditions and executing the entry/exit/transition actions.

A very useful function is QtScriptedStateMachine::registerObject(), which allows you to add an object (and optionally all its descendants) to the scripting context. QtScriptedStateMachine::scriptEngine() allows you to manipulate the scripting context directly. Use the mediaplayer example as a reference for using the registerObject function.

- -

Connecting the state-machine to signals/slots

A simpler way to interact with the state machine is through signals and slots. The slot QtScriptedStateMachine::postNamedEvent() and the signal QtScriptedStateMachine::eventTriggered() allow for a simple interaction with the state machine, as you can connect signals to postNamedEvent and eventTriggered to and signal/slot.

There are no entered/exited signals from states, as that would make the state-machines less deterministic and would create results that are difficult to manage and predict (does the signal get emitted before, after or during the normal execution list?)

The calc example shows the usage of QtScriptedStateMachine::postNamedEvent().

- -

Extending the state-machine with custom invokers

A custom invoker allows you to write your own invoke tags, and implement specific invoke types, as described in the SCXML standard.

To create a custom invoker, you must subclass from QtSsmInvoker, and implement at least:

A constructor with QtScriptedEvent and QtStateMachine arguments
The QtSsmInvoker::activate() function
A static bool isTypeSupportedString(QString) function, conforms to the invoke element's type attribute
A static void initInvokerFactory(QtScriptedStateMachine*) function, allows some initialization (like adding properties to the script engine)

When these terms are met, you can create an invoke-factory, and register it to the state machine. Example:

     #include <QtScriptedStateMachine>
-
-     class MyInvoker : public QtSsmInvoker
-     {
-         Q_OBJECT
-         public:
-             MyInvoker(QtScriptedEvent* ievent, QtScriptedStateMachine* p) : QtSsmInvoker(ievent,p),menu(0)
-             {
-             }
-             static void initInvokerFactory(QtScriptedStateMachine* machine)
-             {
-                 machine->scriptEngine()->globalObject().setProperty("some-name",someValue);
-             }
-             static bool isTypeSupported (const QString & s) { return s== "my-type"; }
-         public Q_SLOTS:
-             void activate ()
-             {
-                 doSomeStuff ();
-             }
-     };
- ...
-     static QSsmAutoInvokerFactory<MyInvoker> _s_factory;
-     myScriptedStateMachine->registerInvoker(&_s_factory);

The initEvent protected member can be used to access the parameters given to the invoker by the calling state machine. QtSsmInvoker::postParentEvent() allows sending events back to the calling state machine.

- -

Loading SCXML files at runtime

To load SCXML files in runtime, the static function QtScriptedStateMachine::load() must be used. Note that this function requires the xmlpatterns and xml modules to be enabled. QtScriptedStateMachine::load() it creates a new QtScriptedStateMachine object. An example code would be:

 #include "qscriptedstatemachine.h"
-
- // some code
- QtScriptedStateMachine* stateMachine = QtScriptedStateMachine::load ("path-to-some-file.scxml");
- // ... register some objects, handle some stuff in the script engine...
- stateMachine->start ();

- -

Supported SCXML tags and features

Though most of the SCXML features are supported in this implementation, the support is incomplete, partially because the spec itself is still evolving. This documentation tries to capture most of the gaps and differences.

- -

Fully supported elements

The tags state, parallel, final, onentry, onexit, raise, if, elseif, else, log, cancel, datamodel,data, assign, param, ands anchor are fully supported according to the scxml spec.

- -

Partially supported elements

scxml: The attributes version, profile and exmode are ignored.
initial: Treated as a regular state that's marked as initial for the parent state.
history: Actions in the history's default transition are ignored.
content: Supports only JSON data, not XML.
send: only the scxml target type is supported. The id attribute is ignored.
invoke: the autoforward and id tags are ignored.

- -

Unsupported elements

The elements donedata, finalize and validate are not supported. Also, the local/global script scoping functionality is not implemented.

- -

Extras

- -

Signal transitions

To declare a signal transition, use a transition tag with a q-signal uri scheme. Example:

     <transition target="someState" event="q-signal:someObject.someSignal()" />

- -

Property binding

The q-binding invoker can be used to setup properties on entry, that are restored on exit. Note that if the properties are changed externally while the state is active, the properties would still be restored.

The binding invoke element accepts a content tag with a JSON array, of which each element is a 3-item array: [object, property-name, property-value].

Example:

      <invoke type="q-bindings"><content>
-                     [[myObject,"someProperty",someValue1 + someValue2],
-                     [myObject,"text","hello"]]
-      </content></invoke>

- -

Menus

A custom invoker added to the solution is the "q-menu" invoker. This invoker allows you to display a QMenu and listen to its events. The q-menu invoker should a content tag, which includes an expression evaluating to an ecmascript object defining the menu. Note that support for menus is currently experimental, and the mediaplayer example demonstrates its use.

- -

Message Boxes

Similar to q-menus, the "q-messagebox" invoker lets you show a QMessageBox and react to the user interactions with it.

The q-messagebox invoker accepts an ecmascript object that contains name/value pairs for the QMessageBox properties.

Example:

         <invoke type="q-messagebox">
-             <content>
-                 {
-                   "parent" : myParentWidget,
-                   "icon" : QMessageBox.Question,
-                   "windowTitle" : "Would you like to exit?",
-                   "text" : "Are you sure?",
-                   "standardButtons" : QMessageBox.Yes|QMessageBox.No
-                 }
-             </content>
-         </invoke>

See the blackjack example for reference.

The State Machine Framework
-

A Simple State Machine
Sharing Transitions By Grouping States
Using History States to Save and Restore the Current State
Using Parallel States to Avoid a Combinatorial Explosion of States
Detecting that a Composite State has Finished

The State Machine framework provides classes for creating and executing state graphs. The concepts and notation are based on those from Harel's Statecharts, which is also the basis of UML state diagrams. The semantics of state machine execution are based on State Chart XML (SCXML).

Statecharts provide a graphical way of modeling how a system reacts to stimuli. This is done by defining the possible states that the system can be in, and how the system can move from one state to another (transitions between states). A key characteristic of event-driven systems (such as Qt applications) is that behavior often depends not only on the last or current event, but also the events that preceded it. With statecharts, this information is easy to express.

The State Machine framework provides an API and execution model that can be used to effectively embed the elements and semantics of statecharts in Qt applications. The framework integrates tightly with Qt's existing event system and meta-object system; for example, transitions between states can be triggered by signals, and states can be configured to set properties and invoke methods on QObjects.

A Simple State Machine

To demonstrate the core functionality of the State Machine API, let's look at a small example: A state machine with three states, s1, s2 and s3. The state machine is controlled by a single QPushButton; when the button is clicked, the machine transitions to another state. Initially, the state machine is in state s1. The statechart for this machine is as follows:

The following snippet shows the code needed to create such a state machine.

 QtStateMachine machine;
- QtState *s1 = new QtState();
- QtState *s2 = new QtState();
- QtState *s3 = new QtState();
-
- s1->addTransition(button, SIGNAL(clicked()), s2);
- s2->addTransition(button, SIGNAL(clicked()), s3);
- s3->addTransition(button, SIGNAL(clicked()), s1);
-
- machine.addState(s1);
- machine.addState(s2);
- machine.addState(s3);
- machine.setInitialState(s1);
-
- machine.start();

Once the state machine has been set up, you need to start it by calling QtStateMachine::start(). The state machine executes asynchronously, i.e. it becomes part of your application's event loop.

The above state machine is perfectly fine, but it doesn't do anything; it merely transitions from one state to another. The QtAbstractState::assignProperty() function can be used to have a state set a property of a QObject when the state is entered. In the following snippet, the value that should be assigned to a QLabel's text property is specified for each state:

 s1->assignProperty(label, "text", "In state s1");
- s2->assignProperty(label, "text", "In state s2");
- s3->assignProperty(label, "text", "In state s3");

When any of the states is entered, the label's text will be changed accordingly.

The QtActionState::invokeMethodOnEntry() function can be used to have a state invoke a method (a slot) of a QObject when the state is entered. In the following snippet, the button's showMaximized() slot will be called when state s3 is entered:

 s2->invokeMethodOnEntry(button, "showMaximized");

Sharing Transitions By Grouping States

The state machine defined in the previous section never finishes. In order for a state machine to be able to finish, it needs to have a top-level final state. When the state machine enters a top-level final state, the machine will emit the finished() signal and halt.

Assume we wanted the user to be able to quit the application at any time by clicking a Quit button. In order to achieve this, we need to create a final state and make it the target of a transition associated with the Quit button's clicked() signal. We could add a transition from each of s1, s2 and s3; however, this seems redundant, and one would also have to remember to add such a transition from every new state that is added in the future.

We can achieve the same behavior (namely that clicking the Quit button quits the state machine, regardless of which state the state machine is in) by grouping states s1, s2 and s3. This is done by creating a new top-level state and making the three original states children of the new state. The following diagram shows the new state machine.

The three original states have been renamed s11, s12 and s13 to reflect that they are now children of the new top-level state, s1. Child states implicitly inherit the transitions of their parent state. This means it is now sufficient to add a single transition from s1 to the final state s2. New states added to s1 will also automatically inherit this transition.

All that's needed to group states is to specify the proper parent when the state is created. You also need to specify which of the child states is the initial one (i.e. which child state the state machine should enter when the parent state is the target of a transition).

 QtState *s1 = new QtState();
- QtState *s11 = new QtState(s1);
- QtState *s12 = new QtState(s1);
- QtState *s13 = new QtState(s1);
- s1->setInitialState(s11);
- machine.addState(s1);

 QtFinalState *s2 = new QtFinalState();
- s1->addTransition(quitButton, SIGNAL(clicked()), s2);
- machine.addState(s2);
-
- QObject::connect(&machine, SIGNAL(finished()), QApplication::instance(), SLOT(quit()));

In this case we want the application to quit when the state machine is finished, so the machine's finished() signal is connected to the application's quit() slot.

A child state can override an inherited transition. For example, the following code adds a transition that effectively causes the Quit button to be ignored when the state machine is in state s12.

 s12>addTransition(quitButton, SIGNAL(clicked()), s12);

- -

Using History States to Save and Restore the Current State

Imagine that we wanted to add an "interrupt" mechanism to the example discussed in the previous section; the user should be able to click a button to have the state machine perform some non-related task, after which the state machine should resume whatever it was doing before (i.e. return to the old state, which is one of s11, s12 and s13 in this case).

Such behavior can easily be modeled using history states. A history state (QtHistoryState object) is a pseudo-state that represents the child state that the parent state was in the last time the parent state was exited.

A history state is created as a child of the state for which we wish to record the current child state; when the state machine detects the presence of such a state at runtime, it automatically records the current (real) child state when the parent state is exited. A transition to the history state is in fact a transition to the child state that the state machine had previously saved; the state machine automatically "forwards" the transition to the real child state.

The following diagram shows the state machine after the interrupt mechanism has been added.

The following code shows how it can be implemented; in this example we simply display a message box when s3 is entered, then immediately return to the previous child state of s1 via the history state.

 QtHistoryState *s1h = s1->addHistoryState();
-
- QtState *s3 = new QtState();
- s3->assignProperty(label, "text", "In s3");
- QMessageBox mbox;
- mbox.addButton(QMessageBox::Ok);
- mbox.setText("Interrupted!");
- mbox.setIcon(QMessageBox::Information);
- s3->invokeMethodOnEntry(&mbox, "exec");
- s3->addTransition(s1h);
- machine.addState(s3);
-
- s1->addTransition(interruptButton, SIGNAL(clicked()), s3);

Using Parallel States to Avoid a Combinatorial Explosion of States

Assume that you wanted to model a set of mutually exclusive properties of a car in a single state machine. Let's say the properties we are interested in are Clean vs Dirty, and Moving vs Not moving. It would take four mutually exclusive states and eight transitions to be able to represent and freely move between all possible combinations.

If we added a third property (say, Red vs Blue), the total number of states would double, to eight; and if we added a fourth property (say, Enclosed vs Convertible), the total number of states would double again, to 16.

Using parallel states, the total number of states and transitions grows linearly as we add more properties, instead of exponentially. Furthermore, states can be added to or removed from the parallel state without affecting any of their sibling states.

To create a parallel state group, pass QtState::ParallelStateGroup to the QtState constructor.

 QtState *s1 = new QtState(QtState::ParallelStateGroup);
- // s11 and s12 will be entered in parallel
- QtState *s11 = new QtState(s1);
- QtState *s12 = new QtState(s1);

Detecting that a Composite State has Finished

A child state can be final; when a final child state is entered, a QtStateFinishedEvent is generated for the parent state. You can use the QtStateFinishedTransition class to trigger a transition based on this event.

This is useful when you want to hide the internal details of a state; i.e. the only thing the outside world should be able to do is enter the state, and get a notification when the state has finished (i.e. when a final child state has been entered).

The concepts and notation are based on those from Harel's - \l{Statecharts: A visual formalism for complex systems}{Statecharts}, which - is also the basis of UML state diagrams. The semantics of state machine - execution are based on \l{State Chart XML: State Machine Notation for - Control Abstraction}{State Chart XML (SCXML)}. - - Statecharts provide a graphical way of modeling how a system reacts to - stimuli. This is done by defining the possible \e states that the system can - be in, and how the system can move from one state to another (\e transitions - between states). A key characteristic of event-driven systems (such as Qt - applications) is that behavior often depends not only on the last or current - event, but also the events that preceded it. With statecharts, this - information is easy to express. - - The State Machine framework provides an API and execution model that can be - used to effectively embed the elements and semantics of statecharts in Qt - applications. The framework integrates tightly with Qt's existing event - system and meta-object system; for example, transitions between states can - be triggered by signals, and states can be configured to set properties and - invoke methods on QObjects. - - \section1 A Simple State Machine - - To demonstrate the core functionality of the State Machine API, let's look - at a small example: A state machine with three states, \c s1, \c s2 and \c - s3. The state machine is controlled by a single QPushButton; when the button - is clicked, the machine transitions to another state. Initially, the state - machine is in state \c s1. The statechart for this machine is as follows: - - \img statemachine-button.png - \omit - \caption This is a caption - \endomit - - The following snippet shows the code needed to create such a state machine. - - \code - QtStateMachine machine; - QtState *s1 = new QtState(); - QtState *s2 = new QtState(); - QtState *s3 = new QtState(); - - s1->addTransition(button, SIGNAL(clicked()), s2); - s2->addTransition(button, SIGNAL(clicked()), s3); - s3->addTransition(button, SIGNAL(clicked()), s1); - - machine.addState(s1); - machine.addState(s2); - machine.addState(s3); - machine.setInitialState(s1); - - machine.start(); - \endcode - - Once the state machine has been set up, you need to start it by calling - QtStateMachine::start(). The state machine executes asynchronously, i.e. it - becomes part of your application's event loop. - - The above state machine is perfectly fine, but it doesn't \e do anything; it - merely transitions from one state to another. The - QtAbstractState::assignProperty() function can be used to have a state set a - property of a QObject when the state is entered. In the following snippet, - the value that should be assigned to a QLabel's text property is specified - for each state: - - \code - s1->assignProperty(label, "text", "In state s1"); - s2->assignProperty(label, "text", "In state s2"); - s3->assignProperty(label, "text", "In state s3"); - \endcode - - When any of the states is entered, the label's text will be changed - accordingly. - - The QtActionState::invokeMethodOnEntry() function can be used to have a state - invoke a method (a slot) of a QObject when the state is entered. In the - following snippet, the button's showMaximized() slot will be called when - state \c s3 is entered: - - \code - s2->invokeMethodOnEntry(button, "showMaximized"); - \endcode - - \section1 Sharing Transitions By Grouping States - - The state machine defined in the previous section never finishes. In order - for a state machine to be able to finish, it needs to have a top-level \e - final state. When the state machine enters a top-level final state, the - machine will emit the finished() signal and halt. - - Assume we wanted the user to be able to quit the application at any time by - clicking a Quit button. In order to achieve this, we need to create a final - state and make it the target of a transition associated with the Quit - button's clicked() signal. We could add a transition from each of \c s1, \c - s2 and \c s3; however, this seems redundant, and one would also have to - remember to add such a transition from every new state that is added in the - future. - - We can achieve the same behavior (namely that clicking the Quit button quits - the state machine, regardless of which state the state machine is in) by - grouping states \c s1, \c s2 and \c s3. This is done by creating a new - top-level state and making the three original states children of the new - state. The following diagram shows the new state machine. - - \img statemachine-button-nested.png - \omit - \caption This is a caption - \endomit - - The three original states have been renamed \c s11, \c s12 and \c s13 to - reflect that they are now children of the new top-level state, \c s1. Child - states implicitly inherit the transitions of their parent state. This means - it is now sufficient to add a single transition from \c s1 to the final - state \c s2. New states added to \c s1 will also automatically inherit this - transition. - - All that's needed to group states is to specify the proper parent when the - state is created. You also need to specify which of the child states is the - initial one (i.e. which child state the state machine should enter when the - parent state is the target of a transition). - - \code - QtState *s1 = new QtState(); - QtState *s11 = new QtState(s1); - QtState *s12 = new QtState(s1); - QtState *s13 = new QtState(s1); - s1->setInitialState(s11); - machine.addState(s1); - \endcode - - \code - QtFinalState *s2 = new QtFinalState(); - s1->addTransition(quitButton, SIGNAL(clicked()), s2); - machine.addState(s2); - - QObject::connect(&machine, SIGNAL(finished()), QApplication::instance(), SLOT(quit())); - \endcode - - In this case we want the application to quit when the state machine is - finished, so the machine's finished() signal is connected to the - application's quit() slot. - - A child state can override an inherited transition. For example, the - following code adds a transition that effectively causes the Quit button to - be ignored when the state machine is in state \c s12. - - \code - s12>addTransition(quitButton, SIGNAL(clicked()), s12); - \endcode - - \section1 Using History States to Save and Restore the Current State - - Imagine that we wanted to add an "interrupt" mechanism to the example - discussed in the previous section; the user should be able to click a button - to have the state machine perform some non-related task, after which the - state machine should resume whatever it was doing before (i.e. return to the - old state, which is one of \c s11, \c s12 and \c s13 in this case). - - Such behavior can easily be modeled using \e{history states}. A history - state (QtHistoryState object) is a pseudo-state that represents the child - state that the parent state was in the last time the parent state was - exited. - - A history state is created as a child of the state for which we wish to - record the current child state; when the state machine detects the presence - of such a state at runtime, it automatically records the current (real) - child state when the parent state is exited. A transition to the history - state is in fact a transition to the child state that the state machine had - previously saved; the state machine automatically "forwards" the transition - to the real child state. - - The following diagram shows the state machine after the interrupt mechanism - has been added. - - \img statemachine-button-history.png - \omit - \caption This is a caption - \endomit - - The following code shows how it can be implemented; in this example we - simply display a message box when \c s3 is entered, then immediately return - to the previous child state of \c s1 via the history state. - - \code - QtHistoryState *s1h = s1->addHistoryState(); - - QtState *s3 = new QtState(); - s3->assignProperty(label, "text", "In s3"); - QMessageBox mbox; - mbox.addButton(QMessageBox::Ok); - mbox.setText("Interrupted!"); - mbox.setIcon(QMessageBox::Information); - s3->invokeMethodOnEntry(&mbox, "exec"); - s3->addTransition(s1h); - machine.addState(s3); - - s1->addTransition(interruptButton, SIGNAL(clicked()), s3); - \endcode - - \section1 Using Parallel States to Avoid a Combinatorial Explosion of States - - Assume that you wanted to model a set of mutually exclusive properties of a - car in a single state machine. Let's say the properties we are interested in - are Clean vs Dirty, and Moving vs Not moving. It would take four mutually - exclusive states and eight transitions to be able to represent and freely - move between all possible combinations. - - \img statemachine-nonparallel.png - \omit - \caption This is a caption - \endomit - - If we added a third property (say, Red vs Blue), the total number of states - would double, to eight; and if we added a fourth property (say, Enclosed vs - Convertible), the total number of states would double again, to 16. - - Using parallel states, the total number of states and transitions grows - linearly as we add more properties, instead of exponentially. Furthermore, - states can be added to or removed from the parallel state without affecting - any of their sibling states. - - \img statemachine-parallel.png - \omit - \caption This is a caption - \endomit - - To create a parallel state group, pass QtState::ParallelStateGroup to the - QtState constructor. - - \code - QtState *s1 = new QtState(QtState::ParallelStateGroup); - // s11 and s12 will be entered in parallel - QtState *s11 = new QtState(s1); - QtState *s12 = new QtState(s1); - \endcode - - \section1 Detecting that a Composite State has Finished - - A child state can be final; when a final child state is entered, a - QtStateFinishedEvent is generated for the parent state. You can use the - QtStateFinishedTransition class to trigger a transition based on this event. - - \img statemachine-finished.png - \omit - \caption This is a caption - \endomit - - This is useful when you want to hide the internal details of a state; - i.e. the only thing the outside world should be able to do is enter the - state, and get a notification when the state has finished (i.e. when a final - child state has been entered). - - */ diff --git a/lib/qtstatemachine/examples/blackjack/bj.qrc b/lib/qtstatemachine/examples/blackjack/bj.qrc deleted file mode 100644 index 6e39934..0000000 --- a/lib/qtstatemachine/examples/blackjack/bj.qrc +++ /dev/null @@ -1,5 +0,0 @@ - - - blackjack.scxml - - diff --git a/lib/qtstatemachine/examples/blackjack/blackjack.pro b/lib/qtstatemachine/examples/blackjack/blackjack.pro deleted file mode 100644 index 29c7351..0000000 --- a/lib/qtstatemachine/examples/blackjack/blackjack.pro +++ /dev/null @@ -1,14 +0,0 @@ -# ------------------------------------------------- -# Project created by QtCreator 2008-12-16T16:32:05 -# ------------------------------------------------- -QT += script -DEPENDPATH += . -INCLUDEPATH += . -TARGET = blackjack -CONFIG += console -CONFIG -= app_bundle -TEMPLATE = app -SOURCES += main.cpp -include($$PWD/../../src/qtstatemachine.pri) -FORMS += blackjack.ui -RESOURCES += bj.qrc diff --git a/lib/qtstatemachine/examples/blackjack/blackjack.scxml b/lib/qtstatemachine/examples/blackjack/blackjack.scxml deleted file mode 100644 index 6c98eb5..0000000 --- a/lib/qtstatemachine/examples/blackjack/blackjack.scxml +++ /dev/null @@ -1,305 +0,0 @@ - - - - - - - - - - - [[welcomeLabel,"text","Welcome to Blackjack"]] - - - - - - - - - - - - - { - "parent" : gameWidget, - "icon" : QMessageBox.Question, - "windowTitle" : "Exit Blackjack", - "text" : "Are you sure?", - "standardButtons" : - QMessageBox.Yes|QMessageBox.No - } - - - - - - - - - - - - - - - - - [ - [betEdit,"enabled",true], - [betButton,"enabled",true], - [surrenderButton,"enabled",true], - [welcomeLabel,"text","Please place your bet"] - ] - - - - - - - - - - - - { - "parent" : betEdit, - "icon" : QMessageBox.Warning, - "windowTitle" : "Bet is Too High", - "text" : "Please Place Another Bet", - "standardButtons" : - QMessageBox.Ok - } - - - - - - - - - - - - - - - - - - - - - [ - [welcomeLabel,"text","Hit/Stand?"], - [hitButton,"enabled",true], - [standButton,"enabled",true] - ] - - - - - - - - - - - - - - - - - - - - - - [[welcomeLabel,"text","Game Over"]] - - - - - - - [[newRoundButton,"enabled",true]] - - - - - - - - - - - [[welcomeLabel,"text","You Won!"]] - - - [[welcomeLabel,"text","You Lost..."]] - - - - [[welcomeLabel,"text","You It's a draw."]] - - - - - - - - - - - - - diff --git a/lib/qtstatemachine/examples/blackjack/blackjack.ui b/lib/qtstatemachine/examples/blackjack/blackjack.ui deleted file mode 100644 index 187ec62..0000000 --- a/lib/qtstatemachine/examples/blackjack/blackjack.ui +++ /dev/null @@ -1,174 +0,0 @@ - - - gameWidget - - - - 0 - 0 - 520 - 173 - - - - SCXML Blackjack Example - - - - - - - 6 - - - 9 - - - - - - 18 - - - - - - - - - - - - 16 - - - - color:#660033 - - - - - - - - - - 6 - - - 0 - - - - - Points: - - - - - - - color:#339999 - - - - - - - - - - false - - - 10 - - - false - - - - - - - false - - - Bet - - - - - - - - - 6 - - - 0 - - - - - true - - - New Game - - - - - - - false - - - New Round - - - - - - - false - - - Surrender - - - - - - - false - - - Hit - - - - - - - false - - - Stand - - - - - - - Exit - - - - - - - - - - diff --git a/lib/qtstatemachine/examples/blackjack/main.cpp b/lib/qtstatemachine/examples/blackjack/main.cpp deleted file mode 100644 index e8ea625..0000000 --- a/lib/qtstatemachine/examples/blackjack/main.cpp +++ /dev/null @@ -1,71 +0,0 @@ -/**************************************************************************** -** -** This file is part of a Qt Solutions component. -** -** Copyright (c) 2009 Nokia Corporation and/or its subsidiary(-ies). -** -** Contact: Qt Software Information (qt-info@nokia.com) -** -** Commercial Usage -** Licensees holding valid Qt Commercial licenses may use this file in -** accordance with the Qt Solutions Commercial License Agreement provided -** with the Software or, alternatively, in accordance with the terms -** contained in a written agreement between you and Nokia. -** -** GNU Lesser General Public License Usage -** Alternatively, this file may be used under the terms of the GNU Lesser -** General Public License version 2.1 as published by the Free Software -** Foundation and appearing in the file LICENSE.LGPL included in the -** packaging of this file.

QtStateMachine is part of \l{The State Machine - Framework}. - - A state machine manages a set of states (QtAbstractState objects) and - transitions (QtAbstractTransition objects) between those states; the states - and the transitions collectively define a state graph. Once a state graph - has been defined, the state machine can execute it. QtStateMachine's - execution algorithm is based on the \l{State Chart XML: State Machine - Notation for Control Abstraction}{State Chart XML (SCXML)} algorithm. - - The QtState class provides a state that you can use to set properties and - invoke methods on QObjects when the state is entered or exited. This is - typically used in conjunction with \l{Signals and Slots}{signals}; the - signals determine the flow of the state graph, whereas the states' property - assignments and method invocations are the actions. - - Use the addState() function to add a state to the state machine; - alternatively, pass the machine's rootState() to the state constructor. Use - the removeState() function to remove a state from the state machine. - - The following snippet shows a state machine that will finish when a button - is clicked: - - \code - QPushButton button; - - QtStateMachine machine; - QtState *s1 = new QtState(); - s1->assignProperty(&button, "text", "Click me"); - - QtFinalState *s2 = new QtFinalState(); - s1->addTransition(&button, SIGNAL(clicked()), s2); - - machine.addState(s1); - machine.addState(s2); - machine.setInitialState(s1); - machine.start(); - \endcode - - The setInitialState() function sets the state machine's initial state; this - state is entered when the state machine is started. - - The start() function starts the state machine. The state machine executes - asynchronously, i.e. you need to run an event loop in order for it to make - progress. The started() signal is emitted when the state machine has entered - the initial state. - - The state machine processes events and takes transitions until a top-level - final state is entered; the state machine then emits the finished() signal. - - The stop() function stops the state machine. The stopped() signal is emitted - when the state machine has stopped. - - The postEvent() function posts an event to the state machine. This is useful - when you are using custom events to trigger transitions. - - The rootState() function returns the state machine's root state. All - top-level states have the root state as their parent. - - \sa QtAbstractState, QtAbstractTransition -*/ - -/*! - \property QtStateMachine::rootState - - \brief the root state of this state machine -*/ - -/*! - \property QtStateMachine::initialState - - \brief the initial state of this state machine -*/ - -/*! - \property QtStateMachine::errorState - - \brief the error state of this state machine -*/ - -/*! - \property QtStateMachine::errorString - - \brief the error string of this state machine -*/ - -// #define QSTATEMACHINE_DEBUG - -QtStateMachinePrivate::QtStateMachinePrivate() -{ - state = NotRunning;

Constant	Value	Description
`QtState::ShallowHistory`	`0`	Only the immediate child states of the parent state are recorded. In this case a transition with the history state as its target will end up in the immediate child state that the parent was in the last time it was exited. This is the default.
`QtState::DeepHistory`	`1`	Nested states are recorded. In this case a transition with the history state as its target will end up in the most deeply nested descendant state the parent was in the last time it was exited.

Constant	Value	Description
`QtState::Normal`	`0`	A normal state. If the state has no child states, it is an atomic state; otherwise, the child states are mutually exclusive and an initial state must be set by calling QtState::setInitialState().
`QtState::ParallelGroup`	`1`	The state is a parallel group state. When a parallel group state is entered, all its child states are entered in parallel.

Constant	Value	Description
`QtStateMachine::NoError`	`0`	No error has occurred.
`QtStateMachine::NoInitialStateError`	`1`	The machine has entered a QtState with children which does not have an initial state set. The context of this error is the state which is missing an initial state.
`QtStateMachine::NoDefaultStateInHistoryState`	`2`	The machine has entered a QtHistoryState which does not have a default state set. The context of this error is the QtHistoryState which is missing a default state.

QtScriptedEvent	Stands for a general named event with a list of parameter names and parameter values
QtScriptedStateMachine	Way to use scripting with the Qt State Machine Framework
QtScriptedTransition	Stands for a transition that responds to QtScriptedEvent, and can be made conditional with a
QtSsmInvoker	Invoker, which the state-machine context can activate or cancel with an <invoke> tag

QtAbstractState	The base class of states of a QtStateMachine
QtAbstractTransition	The base class of transitions between QtAbstractState objects
QtActionState	Action-based state
QtEventTransition	QObject-specific transition for Qt events
QtFinalState	Final state
QtHistoryState	Means of returning to a previously active substate
QtSignalEvent	Represents a Qt signal event
QtSignalTransition	Transition based on a Qt signal
QtState	General-purpose state for QtStateMachine
QtStateAction	The base class of QtState actions
QtStateFinishedEvent	Contains parameters that describe a state that has finished
QtStateFinishedTransition	Transition that triggers when a state is finished
QtStateInvokeMethodAction	Invoke method action for QObjects
QtStateMachine	Hierarchical finite state machine
QtTransition	Action-based transition
