-    \example statemachine/eventtransitions
-    \title Event Transitions Example
-
-    \brief The Event Transitions example shows how to use event transitions,
-    a feature of \l{The State Machine Framework}.
-
-    The Event Transitions Example illustrates how states change when a
-    user enters or leaves the area of a button. The states are handled by
-    a QStateMachine object. The screen consists of a QVBoxLayout with a
-    central button.
-
-    When the mouse is outside the button, the text in the button displays
-    "Outside". When the mouse enters the button, it displays "Inside".
-
-    \borderedimage transitions.png
-
-    \snippet statemachine/eventtransitions/main.cpp 0
-
-    The \c Window class's constructors begins by creating a button.
-    This button is added to  \c layout, which is a QVBoxLayout object.
-    Then two states are created: \c s1 is the state
-    "Outside", and \c s2 is the state "Inside".
-
-    \snippet statemachine/eventtransitions/main.cpp 1
-
-    State \c s1 is the state "Outside" and state \c s2 is state "Inside".
-
-    \snippet statemachine/eventtransitions/main.cpp 2
-
-    When the button receives an event of type QEvent::Enter and the state
-    machine is in state \c s1, the machine will transition to state \c s2.
-
-    \snippet statemachine/eventtransitions/main.cpp 3
-
-    When the button receives an event of type QEvent::Leave and the state
-    machine is in state \c s2, the machine will transition back to state \c
-    s1.
-
-    \snippet statemachine/eventtransitions/main.cpp 4
-
-    Next, state \c s3 is created. \c s3 will be entered when the button
-    receives an event of type QEvent::MouseButtonPress and the state machine
-    is in state \c s2. When the button receives an event of type
-    QEvent::MouseButtonRelease and the state machine is in state \c s3, the
-    machine will revert to state \c s2.
-
-    \snippet statemachine/eventtransitions/main.cpp 5
-
-    Finally, the states are added to the machine as top-level states, the
-    initial state is set to be \c s1 ("Outside"), and the machine is started.
-
-    \snippet statemachine/eventtransitions/main.cpp 6
-
-    The main() function constructs a Window object that displays the QVBoxLayout
-    object \c layout with its \c button.

-
-    \brief The Factorial States example shows how to use \l{The State Machine
-    Framework} to calculate the factorial of an integer.
-
-    The statechart for calculating the factorial looks as follows:

-    \caption This is a caption
-    \endomit
-
-    In other words, the state machine calculates the factorial of 6 and prints
-    the result.
-
-    \snippet statemachine/factorial/main.cpp 0
-
-    The Factorial class is used to hold the data of the computation, \c x and
-    \c fac. It also provides a signal that's emitted whenever the value of \c
-    x changes.
-
-    \snippet statemachine/factorial/main.cpp 1
-
-    The FactorialLoopTransition class implements the guard (\c x > 1) and
-    calculations (\c fac = \c x * \c fac; \c x = \c x - 1) of the factorial
-    loop.
-
-    \snippet statemachine/factorial/main.cpp 2
-
-    The FactorialDoneTransition class implements the guard (\c x <= 1) that
-    terminates the factorial computation. It also prints the final result to
-    standard output.
-
-    \snippet statemachine/factorial/main.cpp 3
-
-    The application's main() function first creates the application object, a
-    Factorial object and a state machine.
-
-    \snippet statemachine/factorial/main.cpp 4
-
-    The \c compute state is created, and the initial values of \c x and \c fac
-    are defined. A FactorialLoopTransition object is created and added to the
-    state.
-
-    \snippet statemachine/factorial/main.cpp 5
-
-    A final state, \c done, is created, and a FactorialDoneTransition object
-    is created with \c done as its target state. The transition is then added
-    to the \c compute state.
-
-    \snippet statemachine/factorial/main.cpp 6
-
-    The machine's initial state is set to be the \c compute state. We connect
-    the QStateMachine::finished() signal to the QCoreApplication::quit() slot,
-    so the application will quit when the state machine's work is
-    done. Finally, the state machine is started, and the application's event
-    loop is entered.

-    \example animation/moveblocks
-    \title Move Blocks Example
-
-    \brief The Move Blocks example shows how to animate items in a
-    QGraphicsScene using a QStateMachine with a custom transition.
-
-    \image moveblocks-example.png
-
-    The example animates the blue blocks that you can see in the image
-    above. The animation moves the blocks between four preset positions.
-
-    The example consists of the following classes:
-
-    \list
-        \li \c StateSwitcher inherits QState and can add
-              \c {StateSwitchTransition}s to other states.
-              When entered, it will randomly transition to one of these
-              states.
-        \li \c StateSwitchTransition is a custom transition that
-           triggers on \c{StateSwitchEvent}s.
-        \li \c StateSwitchEvent is a QEvent that triggers \c{StateSwitchTransition}s.
-        \li \c QGraphicsRectWidget is a QGraphicsWidget that simply
-           paints its background in a solid \l{Qt::}{blue} color.
-    \endlist
-
-    The blocks are instances of \c QGraphicsRectWidget and are
-    animated in a QGraphicsScene. We do this by building a state
-    graph, which we insert animations into. The graph is then executed
-    in a QStateMachine. All this is done in \c main().
-    Let's look at the \c main() function first.
-
-    \section1 The \c main() Function
-
-    After QApplication has been initialized, we set up the
-    QGraphicsScene with its \c{QGraphicsRectWidget}s.
-
-    \snippet animation/moveblocks/main.cpp 1
-
-    After adding the scene to a QGraphicsView, it is time to build the
-    state graph. Let's first look at a statechart of what we are
-    trying to build.
-
-    \image move-blocks-chart.png
-
-    Note that the \c group has seven sub states, but we have only
-    included three of them in the diagram. The code that builds this
-    graph will be examined line-by-line, and will show how the graph
-    works. First off, we construct the \c group state:
-
-    \snippet animation/moveblocks/main.cpp 2
-
-    The timer is used to add a delay between each time the blocks are
-    moved. The timer is started when \c group is entered. As we will
-    see later, \c group has a transition back to the \c StateSwitcher
-    when the timer times out. \c group is the initial state in the
-    machine, so an animation will be scheduled when the example is
-    started.
-
-    \snippet animation/moveblocks/main.cpp 3
-    \dots
-    \snippet animation/moveblocks/main.cpp 4
-
-    \c createGeometryState() returns a QState that will set the
-    geometry of our items upon entry. It also assigns \c group as the
-    parent of this state.
-
-    A QPropertyAnimation inserted into a transition will use the
-    values assigned to a QState (with QState::assignProperty()), i.e.,
-    the animation will interpolate between the current values of the
-    properties and the values in the target state. We add animated
-    transitions to the state graph later.
-
-    \snippet animation/moveblocks/main.cpp 5
-
-    We move the items in parallel. Each item is added to \c
-    animationGroup, which is the animation that is inserted into the
-    transitions.
-
-    \snippet animation/moveblocks/main.cpp 6
-
-    The sequential animation group, \c subGroup, helps us insert a
-    delay between the animation of each item.
-
-    \snippet animation/moveblocks/main.cpp 7
-    \dots
-    \snippet animation/moveblocks/main.cpp 8
-
-    A StateSwitchTransition is added to the state switcher
-    in \c StateSwitcher::addState(). We also add the animation in this
-    function. Since QPropertyAnimation uses the values from the
-    states, we can insert the same QPropertyAnimation instance in all
-    \c {StateSwitchTransition}s.
-
-    As mentioned previously, we add a transition to the state switcher
-    that triggers when the timer times out.
-
-    \snippet animation/moveblocks/main.cpp 9
-
-    Finally, we can create the state machine, add our initial state,
-    and start execution of the state graph.
-
-    \section2 The \c createGeometryState() Function
-
-    In \c createGeometryState(), we set up the geometry for each
-    graphics item.
-
-    \snippet animation/moveblocks/main.cpp 13
-
-    As mentioned before, QAbstractTransition will set up an animation
-    added with \l{QAbstractTransition::}{addAnimation()} using
-    property values set with \l{QState::}{assignProperty()}.
-
-    \section1 The StateSwitcher Class
-
-    \c StateSwitcher has state switch transitions to each \l{QState}s
-    we created with \c createGeometryState(). Its job is to transition
-    to one of these states at random when it is entered.
-
-    All functions in \c StateSwitcher are inlined. We'll step through
-    its definition.
-
-    \snippet animation/moveblocks/main.cpp 10
-
-    \c StateSwitcher is a state designed for a particular purpose and
-    will always be a top-level state. We use \c m_stateCount to keep
-    track of how many states we are managing, and \c m_lastIndex to
-    remember which state was the last state to which we transitioned.
-
-    \snippet animation/moveblocks/main.cpp 11
-
-    We select the next state we are going to transition to, and post a
-    \c StateSwitchEvent, which we know will trigger the \c
-    StateSwitchTransition to the selected state.
-
-    \snippet animation/moveblocks/main.cpp 12
-
-    This is where the magic happens. We assign a number to each state
-    added. This number is given to both a StateSwitchTransition and to
-    StateSwitchEvents. As we have seen, state switch events will
-    trigger a transition with the same number.
-
-    \section1 The StateSwitchTransition Class
-
-    \c StateSwitchTransition inherits QAbstractTransition and triggers
-    on \c{StateSwitchEvent}s. It contains only inline functions, so
-    let's take a look at its \l{QAbstractTransition::}{eventTest()}
-    function, which is the only function that we define..
-
-    \snippet animation/moveblocks/main.cpp 14
-
-    \c eventTest is called by QStateMachine when it checks whether a
-    transition should be triggered--a return value of true means that
-    it will. We simply check if our assigned number is equal to the
-    event's number (in which case we fire away).
-
-    \section1 The StateSwitchEvent Class
-
-    \c StateSwitchEvent inherits QEvent, and holds a number that has
-    been assigned to a state and state switch transition by
-    \c StateSwitcher. We have already seen how it is used to trigger
-    \c{StateSwitchTransition}s in \c StateSwitcher.
-
-    \snippet animation/moveblocks/main.cpp 15
-
-    We only have inlined functions in this class, so a look at its
-    definition will do.
-
-    \section1 The QGraphicsRectWidget Class
-
-    QGraphicsRectWidget inherits QGraphicsWidget and simply paints its
-    \l{QWidget::}{rect()} blue. We inline \l{QWidget::}{paintEvent()},
-    which is the only function we define. Here is the
-    QGraphicsRectWidget class definition:
-
-    \snippet animation/moveblocks/main.cpp 16
-
-    \section1 Moving On
-
-    The technique shown in this example works equally well for all
-    \l{QPropertyAnimation}s. As long as the value to be animated is a
-    Qt property, you can insert an animation of it into a state graph.
-
-    QState::addAnimation() takes a QAbstractAnimation, so any type
-    of animation can be inserted into the graph.

-/*!
-    \example graphicsview/padnavigator
-    \title Pad Navigator Example
-    \ingroup examples-graphicsview
-    \brief Demonstrates how to create animated user interface.
-
-    The Pad Navigator Example shows how you can use Graphics View together with
-    embedded widgets and Qt's \l{The State Machine Framework}{state machine
-    framework} to create a simple but useful, dynamic, animated user interface.
-
-    \image padnavigator-example.png
-
-    The interface consists of a flippable, rotating pad with icons that can be
-    selected using the arrow keys on your keyboard or keypad. Pressing enter
-    will flip the pad around and reveal its back side, which has a form
-    embedded into a QGraphicsProxyWidget. You can interact with the form, and
-    press the enter key to flip back to the front side of the pad at any time.
-
-    Graphics View provides the QGraphicsScene class for managing and
-    interacting with a large number of custom-made 2D graphical items derived
-    from the QGraphicsItem class, and a QGraphicsView widget for visualizing
-    the items, with support for zooming and rotation.
-
-    This example consists of a \c RoundRectItem class, a \c FlippablePad class,
-    a \c PadNavigator class, a \c SplashItem class, and a \c main() function.
-
-    \section1 RoundRectItem Class Definition
-
-    The \c RoundRectItem class is used by itself to display the icons on the
-    pad, and as a base class for \c FlippablePad, the class for the pad itself.
-    The role of the class is to paint a round rectangle of a specified size and
-    gradient color, and optionally to paint a pixmap icon on top. To support \c
-    FlippablePad it also allows filling its contents with a plain window
-    background color.
-
-    Let's start by reviewing the \c RoundRectItem class declaration.
-
-    \snippet graphicsview/padnavigator/roundrectitem.h 0
-
-    \c RoundRectItem inherits QGraphicsObject, which makes it easy to control
-    its properties using QPropertyAnimation. Its constructor takes a rectangle
-    to determine its bounds, and a color.
-
-    Besides implementing the mandatory \l{QGraphicsItem::paint()}{paint()} and
-    \l{QGraphicsItem::boundingRect()}{boundingRect()} pure virtual functions,
-    it also provides the \c pixmap and \c fill properties.
-
-    The \c pixmap property sets an optional pixmap that is drawn on top of the
-    round rectangle. The \c fill property will, when true, fill the round
-    rectangle contents with a fixed QPalette::Window background color.
-    Otherwise the contents are filled using a gradient based on the color
-    passed to \c RoundRectItem's constructor.
-
-    \snippet graphicsview/padnavigator/roundrectitem.h 1
-
-    The private data members are:
-
-    \list
-    \li \c pix: The optional pixmap that is drawn on top of the rectangle.
-    \li \c fillRect: Corresponds to the \c fill property.
-    \li \c color: The configurable gradient color fill of the rectangle.
-    \li \c bounds: The bounds of the rectangle.
-    \li \c gradient: A precalculated gradient used to fill the rectangle.
-    \endlist
-
-    We will now review the \c RoundRectItem implementation. Let's start by
-    looking at its constructor:
-
-    \snippet graphicsview/padnavigator/roundrectitem.cpp 0
-
-    The constructor initializes its member variables and forwards the \c parent
-    argument to QGraphicsObject's constructor. It then constructs the linear
-    gradient that is used in \l{QGraphicsItem::paint()}{paint()} to draw the
-    round rectangle's gradient background. The linear gradient's starting point
-    is at the top-left corner of the bounds, and the end is at the bottom-left
-    corner. The start color is identical to the color passed as an argument,
-    and a slightly darker color is chosen for the final stop.
-
-    We store this gradient as a member variable to avoid having to recreate the
-    gradient every time the item is repainted.
-
-    Finally we set the cache mode
-    \l{QGraphicsItem::ItemCoordinateCache}{ItemCoordinateCache}. This mode
-    causes the item's rendering to be cached into an off-screen pixmap that
-    remains persistent as we move and transform the item. This mode is ideal
-    for this example, and works particularly well with OpenGL and OpenGL ES.
-
-    \snippet graphicsview/padnavigator/roundrectitem.cpp 1
-
-    The \c pixmap property implementation simple returns the member pixmap, or
-    sets it and then calls \l{QGraphicsItem::update()}{update()}.
-
-    \snippet graphicsview/padnavigator/roundrectitem.cpp 2
-
-    As the \l{QGraphicsItem::paint()}{paint()} implementation below draws a
-    simple drop shadow down and to the right of the item, we return a slightly
-    adjusted rectangle from \l{QGraphicsItem::boundingRect()}{boundingRect()}.
-
-    \snippet graphicsview/padnavigator/roundrectitem.cpp 3
-
-    The \l{QGraphicsItem::paint()}{paint()} implementation starts by rendering
-    a semi transparent black round rectangle drop shadow, two units down and to
-    the right of the main item.
-
-    \snippet graphicsview/padnavigator/roundrectitem.cpp 4
-
-    We then draw the "foreground" round rectangle itself. The fill depends on
-    the \c fill property; if true, we will with a plain QPalette::Window color.
-    We get the current brush from QApplication::palette(). We assign a single
-    unit wide pen for the stroke, assign the brush, and then draw the
-    rectangle.
-
-    \snippet graphicsview/padnavigator/roundrectitem.cpp 5
-
-    If a pixmap has been assigned to the \e pixmap property, we draw this
-    pixmap in the center of the rectangle item. The pixmaps are scaled to match
-    the size of the icons; in arguably a better approach would have been to
-    store the icons with the right size in the first places.
-
-    \snippet graphicsview/padnavigator/roundrectitem.cpp 6
-
-    Finally, for completeness we include the \c fill property implementation.
-    It returns the \c fill member variable's value, and when assigned to, it
-    calls \l{QGraphicsItem::update()}{update()}.
-
-    As mentioned already, \c RoundRectItem is the base class for \c
-    FlippablePad, which is the class representing the tilting pad itself. We
-    will proceed to reviewing \c FlippablePad.
-
-    \section1 FlippablePad Class Definition
-
-    \c FlippablePad is, in addition to its inherited \c RoundRectItem
-    responsibilities, responsible for creating and managing a grid of icons.
-
-    \snippet graphicsview/padnavigator/flippablepad.h 0
-
-    Its declaration is very simple: It inherits \c RoundRectItem and does not
-    need any special polymorphic behavior. It's suitable to declare its own
-    constructor, and a getter-function that allows \c PadNavigator to access
-    the icons in the grid by (row, column).
-
-    The example has no "real" behavior or logic of any kind, and because of
-    that, the icons do not need to provide any \e behavior or special
-    interactions management. In a real application, however, it would be
-    natural for the \c FlippablePad and its icons to handle more of the
-    navigation logic. In this example, we have chosen to leave this to
-    the \c PadNavigator class, which we will get back to below.
-
-    We will now review the \c FlippablePad implementation. This implementation
-    starts with two helper functions: \c boundsFromSize() and \c
-    posForLocation():
-
-    \snippet graphicsview/padnavigator/flippablepad.cpp 0
-
-    \c boundsForSize() takes a QSize argument, and returns the bounding
-    rectangle of the flippable pad item. The QSize determines how many rows and
-    columns the icon grid should have. Each icon is given 150x150 units of
-    space, and this determines the bounds.
-
-    \snippet graphicsview/padnavigator/flippablepad.cpp 1
-
-    \c posForLocation() returns the position of an icon given its row and
-    column position. Like \c boundsForSize(), the function assumes each icon is
-    given 150x150 units of space, and that all icons are centered around the
-    flippable pad item's origin (0, 0).
-
-    \snippet graphicsview/padnavigator/flippablepad.cpp 2
-
-    The \c FlippablePad constructor passes suitable bounds (using \c
-    boundsForSize()) and specific color to \c RoundRectItem's constructor.
-
-    \snippet graphicsview/padnavigator/flippablepad.cpp 3
-
-    It then loads pixmaps from compiled-in resources to use for its icons.
-    QDirIterator is very useful in this context, as it allows us to fetch all
-    resource "*.png" files inside the \c :/images directory without explicitly
-    naming the files.
-
-    We also make sure not to load more pixmaps than we need.
-
-    \snippet graphicsview/padnavigator/flippablepad.cpp 4
-
-    Now that we have the pixmaps, we can create icons, position then and assign
-    pixmaps. We start by finding a suitable size and color for the icons, and
-    initializing a convenient grid structure for storing the icons. This \c
-    iconGrid is also used later to find the icon for a specific (column, row)
-    location.
-
-    For each row and column in our grid, we proceed to constructing each icon
-    as an instance of \c RoundRectItem. The item is placed by using the \c
-    posForLocation() helper function. To make room for the slip-behind
-    selection item, we give each icon a \l{QGraphicsItem::zValue()}{Z-value} of
-    1. The pixmaps are distributed to the icons in round-robin fasion.
-
-    Again, this approach is only suitable for example purposes. In a real-life
-    application where each icon represents a specific action, it would be more
-    natural to assign the pixmaps directly, or that the icons themselves
-    provide suitable pixmaps.
-
-    \snippet graphicsview/padnavigator/flippablepad.cpp 5
-
-    Finally, the \c iconAt() function returns a pointer to the icon at a
-    specific row and column. It makes a somewhat bold assumption that the input
-    is valid, which is fair because the \c PadNavigator class only calls this
-    function with correct input.
-
-    We will now review the \c SplashItem class.
-
-    \section1 SplashItem Class Definition
-
-    The \c SplashItem class represents the "splash window", a semitransparent
-    white overlay with text that appears immediately after the application has
-    started, and disappears after pressing any key. The animation is controlled
-    by \c PadNavigator; this class is very simple by itself.
-
-    \snippet graphicsview/padnavigator/splashitem.h 0
-
-    The class declaration shows that \c SplashItem inherits QGraphicsObject to
-    allow it to be controlled by QPropertyAnimation. It reimplements the
-    mandatory \l{QGraphicsItem::paint()}{paint()} and
-    \l{QGraphicsItem::boundingRect()}{boundingRect()} pure virtual functions,
-    and keeps a \c text member variable which will contain the information text
-    displayed on this splash item.
-
-    Let's look at its implementation.
-
-    \snippet graphicsview/padnavigator/splashitem.cpp 0
-
-    The constructor forwards to QGraphicsObject as expected, assigns a text
-    message to the \c text member variable, and enables
-    \l{QGraphicsItem::DeviceCoordinateCache}{DeviceCoordinateCache}. This cache
-    mode is suitable because the splash item only moves and is never
-    transformed, and because it contains text, it's important that it has a
-    pixel perfect visual appearance (in constrast to
-    \l{QGraphicsItem::ItemCoordinateCache}{ItemCoordinateCache}, where the
-    visual appearance is not as good).
-
-    We use caching to avoid having to relayout and rerender the text for each
-    frame. An alterative approach would be to use the new QStaticText class.
-
-    \snippet graphicsview/padnavigator/splashitem.cpp 1
-
-    \c SplashItem's bounding rectangle is fixed at (400x175).
-
-    \snippet graphicsview/padnavigator/splashitem.cpp 2
-
-    The \l{QGraphicsItem::paint()}{paint()} implementation draws a clipped
-    round rectangle with a thick 2-unit border and a semi-transparent white
-    background. It proceeds to finding a suitable text area by adjusting the
-    splash item's bounding rectangle with 10 units in each side. The text is
-    rendered inside this rectangle, with top-left alignment, and with word
-    wrapping enabled.
-
-    The main class now remains. We will proceed to reviewing \c PadNavigator.
-
-    \section1 PadNavigator Class Definition
-
-    \c PadNavigator represents the main window of our Pad Navigator Example
-    application. It creates and controls a somewhat complex state machine, and
-    several animations. Its class declaration is very simple:
-
-    \snippet graphicsview/padnavigator/padnavigator.h 0
-
-    It inherits QGraphicsView and reimplements only one function:
-    \l{QGraphicsView::resizeEvent()}{resizeEvent()}, to ensure the scene is
-    scaled to fit inside the view when resizing the main window.
-
-    The \c PadNavigator constructor takes a QSize argument that determines the
-    number or rows and columns in the grid.
-
-    It also keeps a private member instance, \c form, which is the generated
-    code for the pad's back side item's QGraphicsProxyWidget-embedded form.
-
-    \snippet graphicsview/padnavigator/padnavigator.cpp 0
-
-    \c PadNavigator's constructor is a bit long. In short, its job is to create
-    all items, including the \c FlippablePad, the \c SplashItem and the
-    QGraphicsProxyWidget \c backItem, and then to set up all animations, states
-    and transitions that control the behavior of the application.
-
-    It starts out simple, by forwarding to QGraphicsView's constructor.
-
-    \snippet graphicsview/padnavigator/padnavigator.cpp 1
-
-    The first item to be created is \c SplashItem. This is going to be a top-level
-    item in the scene, next to \c FlippablePad, and stacked on top of it, so we
-    assign it a \l{QGraphicsItem::zValue()}{Z-value} of 1.
-
-    \snippet graphicsview/padnavigator/padnavigator.cpp 2
-
-    Now we construct the \c FlippablePad item, passing its column-row count to
-    its constructor.
-
-    The pad is controlled by three transformations, and we create one
-    QGraphicsRotation object for each of these.
-
-    \list
-    \li \c flipRotation: Rotates the grid around its Qt::YAxis. This rotation is
-    animated from 0 to 180, and eventually back, when enter is pressed on the
-    keyboard, flipping the pad around.
-    \li \c xRotation: Rotates the grid around its Qt::XAxis. This is used to
-    tilt the pad vertically corresponding to which item is currently selected.
-    This way, the selected item is always kept in front.
-    \li \c yRotation: Rotates the grid around its Qt::YAxis. This is used to
-    tilt the pad horizontally corresponding to which item is selected. This
-    way, the selected item is always kept in front.
-    \endlist
-
-    The combination of all three rotations is assigned via
-    QGraphicsItem::setTransformations().
-
-    \snippet graphicsview/padnavigator/padnavigator.cpp 3
-
-    Now we construct the QGraphicsProxyWidget-embedded \c backItem. The proxy
-    widget is created as a child of the pad. We create a new QWidget and
-    populate it with the \c form member. To ensure the \c hostName line edit is
-    the first to receive input focus when this item is shown, we call
-    \l{QWidget::setFocus()}{setFocus()} immediately. This will not give the
-    widget focus right away; it will only prepare the item to automatically
-    receive focus once it is shown.
-
-    The QWidget based form is embedded into the proxy widget. The proxy is
-    hidden initially; we only want to show it when the pad is rotated at least
-    90 degrees, and we also rotate the proxy itself by 180 degrees. This way we
-    give the impression that the proxy widget is "behind" the flipped pad, when
-    in fact, it's actually \e{on top of it}.
-
-    We enable \l{QGraphicsItem::ItemCoordinateCache}{ItemCoordinateCache} to
-    ensure the flip animation can run smoothly.
-
-    \snippet graphicsview/padnavigator/padnavigator.cpp 4
-
-    We now create the selection item. This is simply another instance of \c
-    RoundRectItem that is slightly larger than the icons on the pad. We create
-    it as an immediate child of the \c FlippablePad, so the selection item is a
-    sibling to all the icons. By giving it a
-    \l{QGraphicsItem::zValue()}{Z-value} of 0.5 we ensure it will slide between
-    the pad and its icons.
-
-    What follows now is a series of animation initializations.
-
-    \snippet graphicsview/padnavigator/padnavigator.cpp 5
-
-    We begin with the animations that apply to the splash item. The first
-    animation, \c smoothSplashMove, ensures that the "y" property of \c splash
-    will be animated with a 250-millisecond duration
-    \l{QEasingCurve::InQuad}{InQuad} easing function. \c smoothSplashOpacity
-    ensures the opacity of \c splash eases in and out in 250 milliseconds.
-
-    The values are assigned by \c PadNavigator's state machine, which is
-    created later.
-
-    \snippet graphicsview/padnavigator/padnavigator.cpp 6
-
-    These are the animations that control the selection item's movement and the
-    \c xRotation and \c yRotation QGraphicsRotation objects that tilt the pad.
-    All animations have a duration of 125 milliseconds, and they all use the
-    \l{QEasingCurve::InOutQuad}{InOutQuad} easing function.
-
-    \snippet graphicsview/padnavigator/padnavigator.cpp 7
-
-    We now create the animations that control the flip-effect when you press
-    the enter key. The main goal is to rotate the pad by 180 degrees or back.
-
-    \list
-    \li \c smoothFlipRotation: Animates the main 180 degree rotation of the pad.
-    \li \c smoothFlipScale: Scales the pad out and then in again while the pad is rotating.
-    \li \c flipAnimation: A parallel animation group that ensures the above animations are run in parallel.
-    \endlist
-
-    All animations are given a 500 millisecond duration and an
-    \l{QEasingCurve::InOutQuad}{InOutQuad} easing function.
-
-    It's worth taking a close look at \c smoothFlipScale. This animation's
-    start and end values are both 1.0, but at animation step 0.5 the
-    animation's value is 0.7. This means that after 50% of the animation's
-    duration, or 250 milliseconds, the pad will be scaled down to 0.7x of its
-    original size, which gives a great visual effect while flipping.
-
-    \snippet graphicsview/padnavigator/padnavigator.cpp 8
-
-    This section uses a trick to ensure that certain properties are assigned
-    precisely when the flip animation passes 50%, or 90 degrees, rotation. In
-    short, the pad's icons and selection item are all hidden, the pad's \c fill
-    property is enabled, and \c backItem is shown when flipping over. When
-    flipping back, the reverse properties are applied.
-
-    The way this is achieved is by running a sequential animation in parallel
-    to the other animations. This sequence, dubbed \c setVariablesSequence,
-    starts with a 250 millisecond pause, and then executes several animations
-    with a duration of 0. Each animation will ensure that properties are set
-    immediate at this point.
-
-    This approach can also be used to call functions or set any other
-    properties at a specific time while an animation is running.
-
-    \snippet graphicsview/padnavigator/padnavigator.cpp 9
-
-    We will now create the state machine. The whole \c PadNavigator state
-    machinery is controlled by one single state machine that has a
-    straight-forward state structure. The state engine itself is created
-    as a child of the \c PadNavigator itself. We then create three top level
-    states:
-
-    \list
-    \li \c splashState: The initial state where the splash item is visible.
-    \li \c frontState: The base state where the splash is gone and we can see
-    the front side of the pad, and navigate the selection item.
-    \li \c backState: The flipped state where the \c backItem is visible, and we
-    can interact with the QGraphicsProxyWidget-embedded form.
-    \endlist
-
-    \snippet graphicsview/padnavigator/padnavigator.cpp 10
-
-    Each state assigns specific properties to objects on entry. Most
-    interesting perhaps is the assignment of the value 0.0 to the pad's \c
-    flipRotation angle property when in \c frontState, and 180.0 when in \c
-    backState.
-
-    At the end of this section we register default animations with the state
-    engine; these animations will apply to their respective objects and
-    properties for any state transition. Otherwise it's common to assign
-    animations to specific transitions.
-
-    Specifically, we use default animations to control the selection item's
-    movement and tilt rotations. The tilt rotations are set to 0 when the pad
-    is flipped, and restored back to their original values when flipped back.
-
-    The \c splashState state is set as the initial state. This is required
-    before we start the state engine. We proceed with creating some
-    transitions.
-
-    \snippet graphicsview/padnavigator/padnavigator.cpp 11
-
-    QEventTransition defines a very flexible transition type. You can use this
-    class to trigger a transition based on an object receiving an event of a
-    specific type. In this case, we would like to transition from \c
-    splashState into \c frontState if \c PadNavigator receives any key press
-    event (QEvent::KeyPress).
-
-    We register the \c splashItem's animations to this transition to ensure they
-    are used to animate the item's movement and opacity.
-
-    \snippet graphicsview/padnavigator/padnavigator.cpp 12
-
-    We use QKeyEventTransition to capture specific key events. In this case, we
-    detect that the user presses Qt::Key_Return or Qt::Key_Enter, and use this
-    to trigger transitions between \c frontState and backState. We register \c
-    flipAnimation, our complex parallel animation group, with these
-    transitions.
-
-    We continue by defining the states for each of the icons in the grid.
-
-    \snippet graphicsview/padnavigator/padnavigator.cpp 13
-
-    We will use state groups to control transitions between icons. Each icon
-    represents a \e substate of \c frontState. We will then define transitions
-    between the states by detecting key presses, using QKeyEventTransition.
-
-    We start by creating all the substates, and at the same time we create a
-    temporary grid structure for the states to make it easier to find which
-    states represents icons that are up, down, left and to the right each
-    other.
-
-    Once the first substate is known, we set this up as the initial substate of
-    \c frontState. We will use the (0, 0), or top-left, icon for the initial
-    substate. We initialze the selection item's position to be exactly where
-    the top-left icon is.
-
-    \snippet graphicsview/padnavigator/padnavigator.cpp 14
-
-    We can now create four transitions for each icon. Each transition ensures
-    that we move to the state corresponding to which arrow key has been
-    pressed. It's clear from this techinique that we could design any other
-    specific transitions to and from each of the sub states depending on these
-    and other keys.
-
-    \snippet graphicsview/padnavigator/padnavigator.cpp 15
-
-    Also, for each of the icons, we assign suitable values to the \c xRotation
-    and \c yRotation objects' "angle"-properties. If you recall, these
-    properties "tilt" the pad corresponding to which item is currently
-    selected. We ensure each icon is invisible when the pad is flipped, and
-    visible when the pad is not flipped. To ensure the visible property is
-    assigned at the right time, we add property-controlling animations to the
-    \c setVariableSequence animation defined earlier.
-
-    \snippet graphicsview/padnavigator/padnavigator.cpp 16
-
-    We are now finished with all states, transitions, and animations. We now
-    create the scene that will contain all our items. The scene gets a defined
-    background pixmap, and we disable item indexing (as most items in this
-    scene are animated). We add our \c pad item to the scene, and use its
-    bounding rectangle to fixate the scene rectangle. This rectangle is used by
-    the view to find a suitable size for the application window.
-
-    Then the scene is assigned to the view, or in our case, \c PadNavigator
-    itself.
-
-    \snippet graphicsview/padnavigator/padnavigator.cpp 17
-
-    Now that the scene has received its final size, we can position the splash
-    item at the very top, find its fade-out position, and add it to the scene.
-
-    \snippet graphicsview/padnavigator/padnavigator.cpp 18
-
-    The view toggles a few necessary properties:
-
-    \list
-    \li It disables its scroll bars - this application has no use for scroll bars.
-    \li It assigns a minimum size. This is necessary to avoid numerical errors
-    in our fit-in-view \c resizeEvent() implementation.
-    \li It sets \l{QGraphicsView::FullViewportUpdate}{FullViewportUpdate}, to
-    ensure QGraphicsView doesn't spend time figuring out precisely what needs
-    to be redrawn. This application is very simple - if anything changes,
-    everything is updated.
-    \li It enables background caching - this makes no performance difference
-    with OpenGL, but without OpenGL it avoids unnecessary re-scaling of the
-    background pixmap.
-    \li It sets render hints that increase rendering quality.
-    \li If OpenGL is supported, a QOpenGLWidget viewport is assigned to the view.
-    \endlist
-
-    Finally, we start the state engine.
-
-    \snippet graphicsview/padnavigator/padnavigator.cpp 19
-
-    The \l{QGraphicsView::resizeEvent()}{resizeEvent()} implementation calls
-    the base implementation, and then calls QGraphicsView::fitInView() to scale
-    the scene so that it fits perfectly inside the view.
-
-    By resizing the main application window, you can see this effect yourself.
-    The scene contents grow when you make the window larger, and shrink when
-    you make it smaller, while keeping the aspect ratio intact.
-
-    \section1 The main() Function
-
-    \snippet graphicsview/padnavigator/main.cpp 0
-
-    The \c main function creates the QApplication instance, uses
-    Q_INIT_RESOURCE to ensure our compiled-in resources aren't removed by the
-    linker, and then creates a 3x3 \c PadNavigator instance and shows it.
-
-    Our flippable pad shows up with a suitable splash item once control returns
-    to the event loop.
-
-    \section1 Performance Notes
-
-    The example uses OpenGL if this is available, to achieve optimal
-    performance; otherwise perspective tranformations can be quite costly.
-
-    Although this example does use QGraphicsProxyWidget to demonstrate
-    integration of Qt widget components integrated into Graphics View, using
-    QGraphicsProxyWidget comes with a performance penalty, and is therefore not
-    recommended for embedded development.
-
-    This example uses extensive item caching to avoid rerendering of static
-    elements, at the expense of graphics memory.

-    \title Ping Pong States Example
-
-    \brief The Ping Pong States example shows how to use parallel states together
-    with custom events and transitions in \l{The State Machine Framework}.
-
-    This example implements a statechart where two states communicate by
-    posting events to the state machine. The state chart looks as follows:
-
-    \image pingpong-example.png
-    \omit
-    \caption This is a caption
-    \endomit
-
-    The \c pinger and \c ponger states are parallel states, i.e. they are
-    entered simultaneously and will take transitions independently of
-    eachother.
-
-    The \c pinger state will post the first \c ping event upon entry; the \c
-    ponger state will respond by posting a \c pong event; this will cause the
-    \c pinger state to post a new \c ping event; and so on.
-
-    \snippet statemachine/pingpong/main.cpp 0
-
-    Two custom events are defined, \c PingEvent and \c PongEvent.
-
-    \snippet statemachine/pingpong/main.cpp 1
-
-    The \c Pinger class defines a state that posts a \c PingEvent to the state
-    machine when the state is entered.
-
-    \snippet statemachine/pingpong/main.cpp 2
-
-    The \c PingTransition class defines a transition that is triggered by
-    events of type \c PingEvent, and that posts a \c PongEvent (with a delay
-    of 500 milliseconds) to the state machine when the transition is
-    triggered.
-
-    \snippet statemachine/pingpong/main.cpp 3
-
-    The \c PongTransition class defines a transition that is triggered by
-    events of type \c PongEvent, and that posts a \c PingEvent (with a delay
-    of 500 milliseconds) to the state machine when the transition is
-    triggered.
-
-    \snippet statemachine/pingpong/main.cpp 4
-
-    The main() function begins by creating a state machine and a parallel
-    state group.
-
-    \snippet statemachine/pingpong/main.cpp 5
-
-    Next, the \c pinger and \c ponger states are created, with the parallel
-    state group as their parent state. Note that the transitions are \e
-    targetless. When such a transition is triggered, the source state won't be
-    exited and re-entered; only the transition's onTransition() function will
-    be called, and the state machine's configuration will remain the same,
-    which is precisely what we want in this case.
-
-    \snippet statemachine/pingpong/main.cpp 6
-
-    Finally, the group is added to the state machine, the machine is started,
-    and the application event loop is entered.

-    \example statemachine/rogue
-    \title Rogue Example
-
-    \brief The Rogue example shows how to use the Qt state machine for event
-    handling.
-
-    \image rogue-example.png
-
-    This example implements a simple text based game. Do you see the
-    \c{@} in the screenshot? That's you, the rogue. The \c{#}
-    characters are walls, and the dots represent floor. In a real
-    game, other ASCII characters would represent all kinds of objects
-    and creatures, for instance, ancient dragons (\c{D}s) or food
-    rations (\c{%}s). But let's not get carried away. In this game,
-    the rogue is simply running around in an empty room.
-
-    The rogue is moved with the keypad (2, 4, 8, 6). That aside, we
-    have implemented a \c quit command that triggers if the player
-    types \c {q}. The player is then asked if he/she really wants to
-    quit.
-
-    Most games have commands that need more than one key press (we
-    think of consecutive presses, i.e., not of several keys being
-    pressed at the same time). In this game, only the \c quit command
-    falls under this category, but for the sake of argument, let's
-    imagine a fully-fledged game with a rich set of commands. If we
-    were to implement these by catching key events in
-    \l{QWidget::}{keyPressEvent()}, we would have to keep a lot of
-    class member variables to track the sequence of keys already typed
-    (or find some other way of deducing the current state of a
-    command). This can easily lead to spaghetti, which is--as we all
-    well know, I'm sure--unpleasant. With a state machine, on the
-    other hand, separate states can wait for a single key press, and
-    that makes our lives a lot simpler.
-
-    The example consists of two classes:
-
-    \list
-        \li \c Window draws the text display of the game and sets
-            up the state machine. The window also has a status bar
-            above the area in which the rouge moves.
-        \li \c MovementTransition is a transition that carries out
-            a single move of the rogue.
-    \endlist
-
-    Before we embark on a code walkthrough, it is necessary to take a
-    closer look at the design of the machine. Here is a state chart
-    that shows what we want to achieve:
-
-    \image rogue-statechart.png
-
-    The input state waits for a key press to start a new command.
-    When receiving a key it recognizes, it transitions to one of the
-    two commands of the game; though, as we will see, movement is
-    handled by the transition itself. The quit state waits for the
-    player to answer yes or no (by typing \c y or \c n) when asked
-    whether he/she really wants to quit the game.
-
-    The chart demonstrates how we use one state to wait for a single
-    key press. The press received may trigger one of the transitions
-    connected to the state.
-
-    \section1 Window Class Definition
-
-    The \c Window class is a widget that draws the text display of the
-    game. It also sets up the state machine, i.e., creates and
-    connects the states in the machine. It is the key events from this
-    widget that are used by the machine.
-
-    \snippet statemachine/rogue/window.h 0
-
-    \c Direction specifies the direction in which the rogue is to
-    move. We use this in \c movePlayer(), which moves the rogue and
-    repaints the window. The game has a status line above the area in
-    which the rogue moves. The \c status property contains the text of
-    this line. We use a property because the QState class allows
-    setting any Qt \l{Qt's Property System}{property} when entered.
-    More on this later.
-
-    \snippet statemachine/rogue/window.h 1
-
-    The \c map is an array with the characters that are currently
-    displayed. We set up the array in \c setupMap(), and update it
-    when the rogue is moved. \c pX and \c pY is the current position
-    of the rogue. \c WIDTH and \c HEIGHT are macros specifying the
-    dimensions of the map.
-
-    The \c paintEvent() function is left out of this walkthrough. We
-    also do not discuss other code that does not concern the state
-    machine (the \c setupMap(), \c status(), \c setStatus(), \c
-    movePlayer(), and \c sizeHint() functions). If you wish to take a
-    look at the code, click on the link for the \c window.cpp file at
-    the top of this page.
-
-    \section1 Window Class Implementation
-
-    Here is the constructor of \c Window:

-    The player starts off at position (5, 5). We then set up the map
-    and statemachine. Let's proceed with the \c buildMachine()
-    function:
-
-    \snippet statemachine/rogue/window.cpp 2
-
-    We enter \c inputState when the machine is started and from the \c
-    quitState if the user wants to continue playing. We then set the
-    status to a helpful reminder of how to play the game.
-
-    First, the \c Movement transition is added to the input state.
-    This will enable the rogue to be moved with the keypad.  Notice
-    that we don't set a target state for the movement transition. This
-    will cause the transition to be triggered (and the
-    \l{QAbstractTransition::}{onTransition()} function to be invoked),
-    but the machine will not leave the \c inputState. If we had set \c
-    inputState as the target state, we would first have left and then
-    entered the \c inputState again.
-
-    \snippet statemachine/rogue/window.cpp 3
-
-    When we enter \c quitState, we update the status bar of the
-    window.
-
-    \c QKeyEventTransition is a utility class that removes the hassle
-    of implementing transitions for \l{QKeyEvent}s. We simply need to
-    specify the key on which the transition should trigger and the
-    target state of the transition.
-
-    \snippet statemachine/rogue/window.cpp 4
-
-    The transition from \c inputState allows triggering the quit state
-    when the player types \c {q}.
-
-    \snippet statemachine/rogue/window.cpp 5
-
-    The machine is set up, so it's time to start it.
-
-    \section1 The MovementTransition Class
-
-    \c MovementTransition is triggered when the player request the
-    rogue to be moved (by typing 2, 4, 6, or 8) when the machine is in
-    the \c inputState.
-
-    \snippet statemachine/rogue/movementtransition.h 0
-
-    In the constructor, we tell QEventTransition to only send
-    \l{QEvent::}{KeyPress} events to the
-    \l{QAbstractTransition::}{eventTest()} function:
-
-    \snippet statemachine/rogue/movementtransition.h 1
-
-    The KeyPress events come wrapped in \l{QStateMachine::WrappedEvent}s. \c event
-    must be confirmed to be a wrapped event because Qt uses other
-    events internally. After that, it is simply a matter of checking
-    which key has been pressed.
-
-    Let's move on to the \c onTransition() function:
-
-    \snippet statemachine/rogue/movementtransition.h 2
-
-    When \c onTransition() is invoked, we know that we have a
-    \l{QEvent::}{KeyPress} event with 2, 4, 6, or 8, and can ask \c
-    Window to move the player.
-
-    \section1 The Roguelike Tradition
-
-    You might have been wondering why the game features a rogue. Well,
-    these kinds of text based dungeon exploration games date back to a
-    game called, yes, "Rogue". Although outflanked by the technology
-    of modern 3D computer games, roguelikes have a solid community of
-    hard-core, devoted followers.
-
-    Playing these games can be surprisingly addictive (despite the
-    lack of graphics). Angband, the perhaps most well-known rougelike,
-    is found here: \l{http://rephial.org/}.

-    \example animation/stickman
-    \title Stickman Example
-
-    \brief The Stickman example shows how to animate transitions in a state
-    machine to implement key frame animations.
-
-    \image stickman-example.png
-
-    In this example, we will write a small application which animates the joints in a skeleton and
-    projects a stickman figure on top. The stickman can be either "alive" or "dead", and when in the
-    "alive" state, he can be performing different actions defined by key frame animations.
-
-    Animations are implemented as composite states. Each child state of the animation state
-    represents a frame in the animation by setting the position of each joint in the stickman's
-    skeleton to the positions defined for the particular frame. The frames are then bound together
-    with animated transitions that trigger on the source state's propertiesAssigned() signal. Thus,
-    the machine will enter the state representing the next frame in the animation immediately after
-    it has finished animating into the previous frame.
-
-    \image stickman-example1.png
-
-    The states for an animation is constructed by reading a custom animation file format and
-    creating states that assign values to the "position" properties of each of the nodes in the
-    skeleton graph.
-
-    \snippet animation/stickman/lifecycle.cpp 1
-
-    The states are then bound together with signal transitions that listen to the
-    propertiesAssigned() signal.
-
-    \snippet animation/stickman/lifecycle.cpp 2
-
-    The last frame state is given a transition to the first one, so that the animation will loop
-    until it is interrupted when a transition out from the animation state is taken. To get smooth
-    animations between the different key frames, we set a default animation on the state machine.
-    This is a parallel animation group which contains animations for all the "position" properties
-    and will be selected by default when taking any transition that leads into a state that assigns
-    values to these properties.
-
-    \snippet animation/stickman/lifecycle.cpp 3
-
-    Several such animation states are constructed, and are placed together as children of a top
-    level "alive" state which represents the stickman life cycle. Transitions go from the parent
-    state to the child state to ensure that each of the child states inherit them.
-
-    \image stickman-example2.png
-
-    This saves us the effort of connect every state to every state with identical transitions. The
-    state machine  makes sure that transitions between the key frame animations are also smooth by
-    applying the default animation when interrupting one and starting another.
-
-    Finally, there is a transition out from the "alive" state and into the "dead" state. This is
-    a custom transition type called LightningSrikesTransition which samples every second and
-    triggers at random (one out of fifty times on average.)
-
-    \snippet animation/stickman/lifecycle.cpp 4
-
-    When it triggers, the machine will first enter a "lightningBlink" state which uses a timer to
-    pause for a brief period of time while the background color of the scene is white. This gives us
-    a flash effect when the lightning strikes.
-
-    \snippet animation/stickman/lifecycle.cpp 5
-
-    We start and stop a QTimer object when entering and exiting the state. Then we transition into
-    the "dead" state when the timer times out.
-
-    \snippet animation/stickman/lifecycle.cpp 0
-
-    When the machine is in the "dead" state, it will be unresponsive. This is because the "dead"
-    state has no transitions leading out.

-
-    \brief The Traffic Light example shows how to use \l{The State Machine Framework}
-    to implement the control flow of a traffic light.
-
-    \image trafficlight-example.png
-
-    In this example we write a TrafficLightWidget class. The traffic light has
-    three lights: Red, yellow and green. The traffic light transitions from
-    one light to another (red to yellow to green to yellow to red again) at
-    certain intervals.
-
-    \snippet statemachine/trafficlight/main.cpp 0
-
-    The LightWidget class represents a single light of the traffic light. It
-    provides an \c on property and two slots, turnOn() and turnOff(), to turn
-    the light on and off, respectively. The widget paints itself in the color
-    that's passed to the constructor.
-
-    \snippet statemachine/trafficlight/main.cpp 1
-
-    The TrafficLightWidget class represents the visual part of the traffic
-    light; it's a widget that contains three lights arranged vertically, and
-    provides accessor functions for these.
-
-    \snippet statemachine/trafficlight/main.cpp 2
-
-    The createLightState() function creates a state that turns a light on when
-    the state is entered, and off when the state is exited. The state uses a
-    timer, and as we shall see the timeout is used to transition from one
-    LightState to another. Here is the statechart for the light state:

-    \omit
-    \caption This is a caption
-    \endomit
-
-    \snippet statemachine/trafficlight/main.cpp 3
-
-    The TrafficLight class combines the TrafficLightWidget with a state
-    machine.  The state graph has four states: red-to-yellow, yellow-to-green,
-    green-to-yellow and yellow-to-red. The initial state is red-to-yellow;
-    when the state's timer times out, the state machine transitions to
-    yellow-to-green. The same process repeats through the other states.
-    This is what the statechart looks like:
