-    QGraphicsItemAnimation and QTimeLine.
+    This GraphicsView example shows how to implement Drag and Drop in a
+    QGraphicsItem subclass, as well as how to animate items using Qt's
+    \l{Animation Framework}.
 
     \image dragdroprobot-example.png
+
+    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 Robot class, a \c ColorItem class, and a main
+    function: the \c Robot class describes a simple robot consisting of several
+    \c RobotPart derived limbs, including \c RobotHead and \c RobotLimb, the \c
+    ColorItem class provides a draggable colored ellipse, and the \c main()
+    function provides the main application window.
+
+    We will first review the \c Robot class to see how to assemble the
+    different parts so that they can be individually rotated and animated using
+    QPropertyAnimation, and we will then review the \c ColorItem class to
+    demonstrate how to implement Drag and Drop between items. Finally we will
+    review the main() function to see how we can put all the pieces together,
+    to form the final application.
+
+    \section1 Robot Class Definition
+
+    The robot consists of three main classes: the \c RobotHead, the \c
+    RobotTorso, and the \c RobotLimb, which is used for the upper and lower
+    arms and legs. All parts derive from the \c RobotPart class, which in turn
+    inherits \c QGraphicsObject. The \c Robot class itself has no visual
+    appearance and serves only as a root node for the robot.
+
+    Let's start with the \c RobotPart class declaration.
+
+    \snippet examples/graphicsview/dragdroprobot/robot.h 0
+
+    This base class inherits QGraphicsObject. QGraphicsObject provides signals
+    and slots through inheriting QObject, and it also declares QGraphicsItem's
+    properties using Q_PROPERTY, which makes the properties accessible for
+    QPropertyAnimation.
+
+    RobotPart also implements the three most important event handlers for
+    accepting drop events:
+    \l{QGraphicsItem::dragEnterEvent()}{dragEnterEvent()},
+    \l{QGraphicsItem::dragLeaveEvent()}{dragLeaveEvent()}, and
+    \l{QGraphicsItem::dropEvent()}{dropEvent()}.
+
+    The color is stored as a member variable, along with the \c dragOver
+    variable, which we will use later to indicate visually that the limb can
+    accept colors that are is dragged onto it.
+
+    \snippet examples/graphicsview/dragdroprobot/robot.cpp 0
+
+    \c RobotPart's constructor initializes the dragOver member and sets the
+    color to Qt::lightGray. In the constructor body we enable support for
+    accepting drop events by calling
+    \l{QGraphicsItem::setAcceptDrops()}{setAcceptDrops(true)}.
+
+    The rest of this class's implementation is to support Drag and Drop.
+
+    \snippet examples/graphicsview/dragdroprobot/robot.cpp 1
+
+    The \l{QGraphicsItem::dragEnterEvent()}{dragEnterEvent()} handler is called
+    when a Drag and Drop element is dragged into the robot part's area.
+
+    The handler implementation determines whether or not this item as a whole
+    can accept the mime data assiciated with the incoming drag object. \c
+    RobotPart provides a base behavior for all parts that accepts color drops.
+    So if the incoming drag object contains a color, the event is accepted, we
+    set \c dragOver to \c true and call update() to help provide positive
+    visual feedback to the user; otherwise the event is ignored, which in turn
+    allows the event to propagate to parent elements.
+
+    \snippet examples/graphicsview/dragdroprobot/robot.cpp 2
+
+    The \l{QGraphicsItem::dragLeaveEvent()}{dragLeaveEvent()} handler is called
+    when a Drag and Drop element is dragged away from the robot part's area.
+    Our implementation simply resets \e dragOver to false and calls
+    \l{QGraphicsItem::update()}{update()} to help provide visual feedback that
+    the drag has left this item.
+
+    \snippet examples/graphicsview/dragdroprobot/robot.cpp 3
+
+    The \l{QGraphicsItem::dropEvent()}{dropEvent()} handler is called when a
+    Drag and Drop element is dropped onto an item (i.e., when the mouse button
+    is released over the item while dragging).
+
+    We reset \c dragOver to false, assign the item's new color, and call
+    \l{QGraphicsItem::update()}{update()}.
+
+    The declaration and implementation of \c RobotHead, \c RobotTorso, and \c
+    RobotLimb are practically identical. We will review \c RobotHead in detail,
+    as this class has one minor difference, and leave the other classes as an
+    exercise for the reader.
+
+    \snippet examples/graphicsview/dragdroprobot/robot.h 1
+
+    The \c RobotHead class inherits \c RobotPart and provides the necessary
+    implementations of \l{QGraphicsItem::boundingRect()}{boundingRect()} and
+    \l{QGraphicsItem::paint()}{paint()}. It also reimplements
+    \l{QGraphicsItem::dragEnterEvent()}{dragEnterEvent()} and dropEvent() to
+    provide special handling of image drops.
+
+    The class contains a private pixmap member that we can use to implement
+    support for accepting image drops.
+
+    \snippet examples/graphicsview/dragdroprobot/robot.cpp 4
+
+    \c RobotHead has a rather plain constructor that simply forwards to
+    \c RobotPart's constructor.
+
+    \snippet examples/graphicsview/dragdroprobot/robot.cpp 5
+
+    The \l{QGraphicsItem::boundingRect()}{boundingRect()} reimplementation
+    returns the extents for the head. Because we want the center of rotation to
+    be the bottom center of the item, we have chosen a bounding rectangle that
+    starts at (-15, -50) and extends to 30 units wide and 50 units tall. When
+    rotating the head, the "neck" will stay still while the top of the head
+    tilts from side to side.
+
+    \snippet examples/graphicsview/dragdroprobot/robot.cpp 6
+
+    In \l{QGraphicsItem::paint()}{paint()} we draw the actual head. The
+    implementation is split into two sections; if an image has been dropped
+    onto the head, we draw the image, otherwise we draw a round rectangular
+    robot head with simple vector graphics.
+
+    For performance reasons, depending on the complexity of what is painted, it
+    can often be faster to draw the head as an image rather than using a
+    sequence of vector operations.
+
+    \snippet examples/graphicsview/dragdroprobot/robot.cpp 7
+
+    The robot head can accept image drops. In order to support this, its
+    reimplementation of \l{QGraphicsItem::dragEnterEvent()}{dragEnterEvent()}
+    checks if the drag object contains image data, and if it does, then the
+    event is accepted. Otherwise we fall back to the base \c RobotPart
+    implementation.
+
+    \snippet examples/graphicsview/dragdroprobot/robot.cpp 8
+
+    To follow up on image support, we must also implement
+    \l{QGraphicsItem::dropEvent()}{dropEvent()}. We check if the drag object
+    contains image data, and if it does, we store this data as a member pixmap
+    and call \l{QGraphicsItem::update()}{update()}. This pixmap is used inside
+    the \l{QGraphicsItem::paint()}{paint()} implementation that we reviewed
+    before.
+
+    \c RobotTorso and \c RobotLimb are similar to \c RobotHead, so let's
+    skip directly to the \c Robot class.
+
+    \snippet examples/graphicsview/dragdroprobot/robot.h 4
+
+    The \c Robot class also inherits \c RobotPart, and like the other parts it
+    also implements \l{QGraphicsItem::boundingRect()}{boundingRect()} and
+    \l{QGraphicsItem::paint()}{paint()}. It provides a rather special
+    implementation, though:
+
+    \snippet examples/graphicsview/dragdroprobot/robot.cpp 9
+
+    Because the \c Robot class is only used as a base node for the rest of the
+    robot, it has no visual representation. Its
+    \l{QGraphicsItem::boundingRect()}{boundingRect()} implementation can
+    therefore return a null QRectF, and its paint() function does nothing.
+
+    \snippet examples/graphicsview/dragdroprobot/robot.cpp 10
+
+    The constuctor starts by setting the flag
+    \l{QGraphicsItem::ItemHasNoContents}{ItemHasNoContents}, which is a minor
+    optimization for items that have no visual appearance.
+
+    We then construct all the robot parts (head, torso, and upper/lower arms
+    and legs). The stacking order is very important, and we use the
+    parent-child hierarchy to ensure the elements rotate and move properly. We
+    construct the torso first, as this is the root element. We then construct
+    the head and pass the torso to \c HeadItem's constructor. This will make
+    the head a child of the torso; if you rotate the torso, the head will
+    follow. The same pattern is applied to the rest of the limbs.
+
+    \snippet examples/graphicsview/dragdroprobot/robot.cpp 11
+
+    Each robot part is carefully positioned. For example, the upper left arm is
+    moved precisely to the top-left area of the torso, and the upper right arm
+    is moved to the top-right area.
+
+    \snippet examples/graphicsview/dragdroprobot/robot.cpp 12
+
+    The next section creates all animation objects. This snippet shows the two
+    animations that operate on the head's scale and rotation. The two
+    QPropertyAnimation instances simply set the object, property, and
+    respective start and end values.
+
+    All animations are controlled by one top-level parallel animation group.
+    The scale and rotation animations are added to this group.
+
+    The rest of the animations are defined in a similar way.
+
+    \snippet examples/graphicsview/dragdroprobot/robot.cpp 13
+
+    Finally we set an easing curve and duration on each animation, ensure the
+    toplevel animation group loops forever, and start the toplevel animation.
+
+    \section1 ColorItem Class Definition
+
+    The \c ColorItem class represents a circular item that can be pressed to
+    drag colors onto robot parts.
+
+    \snippet examples/graphicsview/dragdroprobot/coloritem.h 0
+
+    This class is very simple. It does not use animations, and has no need for
+    properties nor signals and slots, so to save resources, it's most natural
+    that it inherits QGraphicsItem (as opposed to QGraphicsObject).
+
+    It declares the mandatory \l{QGraphicsItem::boundingRect()}{boundingRect()}
+    and \l{QGraphicsItem::paint()}{paint()} functions, and adds
+    reimplementations of
+    \l{QGraphicsItem::mousePressEvent()}{mousePressEvent()},
+    \l{QGraphicsItem::mouseMoveEvent()}{mouseMoveEvent()}, and
+    \l{QGraphicsItem::mouseReleaseEvent()}{mouseReleaseEvent()}. It contains a
+    single private color member.
+
+    Let's take a look at its implementation.
+
+    \snippet examples/graphicsview/dragdroprobot/coloritem.cpp 0
+
+    \c ColorItem's constructor assigns an opaque random color to its color
+    member by making use of qrand(). For improved usability, it assigns a
+    tooltip that provides a useful hint to the user, and it also sets a
+    suitable cursor. This ensures that the cursor will chance to
+    Qt::OpenHandCursor when the mouse pointer hovers over the item.
+
+    Finally, we call
+    \l{QGraphicsItem::setAcceptedMouseButtons()}{setAcceptedMouseButtons()} to
+    ensure that this item can only process Qt::LeftButton. This simplifies the
+    mouse event handlers greatly, as we can always assume that only the left
+    mouse button is pressed and released.
+
+    \snippet examples/graphicsview/dragdroprobot/coloritem.cpp 1
+
+    The item's bounding rect is a fixed 30x30 units centered around the item's
+    origin (0, 0), and adjusted by 0.5 units in all directions to allow a
+    scalable pen to draw its outline. For a final visual touch the bounds
+    also compensate with a few units down and to the right to make room
+    for a simple dropshadow.
+
+    \snippet examples/graphicsview/dragdroprobot/coloritem.cpp 2
+
+    The \l{QGraphicsItem::paint()}{paint()} implementation draws an ellipse
+    with a 1-unit black outline, a plain color fill, and a dark gray
+    dropshadow.
+
+    \snippet examples/graphicsview/dragdroprobot/coloritem.cpp 3
+
+    The \l{QGraphicsItem::mousePressEvent()}{mousePressEvent()} handler is
+    called when you press the mouse button inside the item's area. Our
+    implementation simply sets the cursor to Qt::ClosedHandCursor.
+
+    \snippet examples/graphicsview/dragdroprobot/coloritem.cpp 4
+
+    The \l{QGraphicsItem::mouseReleaseEvent()}{mouseReleaseEvent()} handler is
+    called when you release the mouse button after having pressed it inside an
+    item's area. Our implementation sets the cursor back to Qt::OpenHandCursor.
+    The mouse press and release event handlers together provide useful visual
+    feedback to the user: when you move the mouse pointer over a \c CircleItem,
+    the cursor changes to an open hand. Pressing the item will show a closed
+    hand cursor. Releasing will restore to an open hand cursor again.
+
+    \snippet examples/graphicsview/dragdroprobot/coloritem.cpp 5
+
+    The \l{QGraphicsItem::mouseMoveEvent()}{mouseMoveEvent()} handler is called
+    when you move the mouse around after pressing the mouse button inside the
+    \c ColorItem's area. This implementation provides the most important piece
+    of logic for \c CircleItem: the code that starts and manages drags.
+
+    The implementation starts by checking if the mouse has been dragged far
+    enough to eliminate mouse jitter noise. We only want to start a drag if the
+    mouse has been dragged farther than the application start drag distance.
+
+    Continuing, we create a QDrag object, passing the event
+    \l{QGraphicsSceneEvent::widget()}{widget} (i.e., the QGraphicsView
+    viewport) to its constructor. Qt will ensure that this object is deleted at
+    the right time. We also create a QMimeData instance that can contain our
+    color or image data, and assign this to the drag object.
+
+    \snippet examples/graphicsview/dragdroprobot/coloritem.cpp 6
+
+    This snippet has a somewhat random outcome: once in a while, a special
+    image is assigned to the drag object's mime data. The pixmap is also
+    assiged as the drag object's pixmap. This will ensure that you can see the
+    image that is being dragged as a pixmap under the mouse cursor.
+
+    \snippet examples/graphicsview/dragdroprobot/coloritem.cpp 7
+
+    Otherwise, and this is the most common outcome, a simple color is assigned
+    to the drag object's mime data. We render this \c ColorItem into a new
+    pixmap to give the user visual feedback that the color is being "dragged".
+
+    \snippet examples/graphicsview/dragdroprobot/coloritem.cpp 8
+
+    Finally we execute the drag. QDrag::exec() will reenter the event loop, and
+    only exit if the drag has either been dropped, or canceled. In any case we
+    reset the cursor to Qt::OpenHandCursor.
+
+    \section1 The main() Function
+
+    Now that the \c Robot and \c ColorItem classes are complete, we can put all
+    the pieces together inside the main() function.
+
+    \snippet examples/graphicsview/dragdroprobot/main.cpp 0
+
+    We start off by constructing QApplication, and initializing the random
+    number generator. This ensures that the color items have different colors
+    every time the application starts.
+
+    \snippet examples/graphicsview/dragdroprobot/main.cpp 1
+
+    We construct a fixed size scene, and create 10 \c ColorItem instances
+    arranged in a circle. Each item is added to the scene.
+
+    In the center of this circle we create one \c Robot instance. The
+    robot is scaled and moved up a few units. It is then added to the scene.
+
+    \snippet examples/graphicsview/dragdroprobot/main.cpp 2
+
+    Finally we create a QGraphicsView window, and assign the scene to it.
+
+    For increased visual quality, we enable antialiasing. We also choose to use
+    bounding rectangle updates to simplify visual update handling.
+    The view is given a fixed sand-colored background, and a window title.
+
+    We then show the view. The animations start immediately after
+    control enters the event loop.

+    This GraphicsView example shows how to implement edges between nodes in a
+    graph, with basic interaction. You can click to drag a node around, and

     \image elasticnodes-example.png
+
+    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 Node class, an \c Edge class, a \c
+    GraphWidget test, and a \c main function: the \c Node class represents
+    draggable yellow nodes in a grid, the \c Edge class represents the lines
+    between the nodes, the \c GraphWidget class represents the application
+    window, and the \c main() function creates and shows this window, and runs
+    the event loop.
+
+    \section1 Node Class Definition
+
+    The \c Node class serves three purposes:
+
+    \list
+    \o Painting a yellow gradient "ball" in two states: sunken and raised.
+    \o Managing connections to other nodes.
+    \o Calculating forces pulling and pushing the nodes in the grid.
+    \endlist
+
+    Let's start by looking at the \c Node class declaration.
+
+    \snippet examples/graphicsview/elasticnodes/node.h 0
+
+    The \c Node class inherits QGraphicsItem, and reimplements the two
+    mandatory functions \l{QGraphicsItem::boundingRect()}{boundingRect()} and
+    \l{QGraphicsItem::paint()}{paint()} to provide its visual appearance. It
+    also reimplements \l{QGraphicsItem::shape()}{shape()} to ensure its hit
+    area has an elliptic shape (as opposed to the default bounding rectangle).
+
+    For edge management purposes the node provides a simple API for adding
+    edges to a node, and for listing all connected edges.
+
+    The \l{QGraphicsItem::advance()}{advance()} reimplementation is called
+    whenever the scene's state advances by one step. The calculateForces()
+    function is called to calculate the forces that push and pull on this node
+    and its neighbors.
+
+   The \c Node class also reimplements
+   \l{QGraphicsItem::itemChange()}{itemChange()} to react to state changes (in
+   this case, position changes), and
+   \l{QGraphicsItem::mousePressEvent()}{mousePressEvent()} and
+   \l{QGraphicsItem::mouseReleaseEvent()}{mouseReleaseEvent()} to update the
+   item's visual appearance.
+
+    We will start reviewing the \c Node implementation by looking at its
+    constructor:
+
+    \snippet examples/graphicsview/elasticnodes/node.cpp 0
+
+    In the constructor, we set the
+    \l{QGraphicsItem::ItemIsMovable}{ItemIsMovable} flag to allow the item to
+    move in response to mouse dragging, and
+    \l{QGraphicsItem::ItemSendsGeometryChanges}{ItemSendsGeometryChanges} to
+    enable \l{QGraphicsItem::itemChange()}{itemChange()} notifications for
+    position and transformation changes. We also enable
+    \l{QGraphicsItem::DeviceCoordinateCache}{DeviceCoordinateCache} to speed up
+    rendering performance. To ensure that the nodes are always stacked on top
+    of edges, we finally set the item's Z value to -1.
+
+    \c Node's constructor takes a \c GraphWidget pointer and stores this as a
+    member variable. We will revisit this pointer later on.
+
+    \snippet examples/graphicsview/elasticnodes/node.cpp 1
+
+    The addEdge() function adds the input edge to a list of attached edges. The
+    edge is then adjusted so that the end points for the edge match the
+    positions of the source and destination nodes.
+
+    The edges() function simply returns the list of attached edges.
+
+    \snippet examples/graphicsview/elasticnodes/node.cpp 2
+
+    The \e calculateForces() function implements the elastic forces effect that
+    pulls and pushes on nodes in the grid. In addition to this algorithm, the
+    user can move one node around with the mouse. Because we do not want the
+    two to interfere, we start by checking if this \c Node is the current mouse
+    grabber item (i.e., QGraphicsScene::mouseGrabberItem()). Because we need to
+    find all neighboring (but not necessarily connected) nodes, we also make
+    sure the item is part of a scene in the first place.
+
+    \snippet examples/graphicsview/elasticnodes/node.cpp 3
+
+    The algorithm has two steps: the first is to calculate the forces that push
+    the nodes apart, and the second is to subtract the forces that pull the
+    nodes together. First we need to find all the nodes in the graph. We call
+    QGraphicsScene::items() to find all items in the scene, and then use
+    qgraphicsitem_cast() to look for \c Node instances.
+
+    We make use of \l{QGraphicsItem::mapFromItem()}{mapFromItem()} to create a
+    vector pointing from this node to each other node, in \l{The Graphics View
+    Coordinate System}{local coordinates}. We use the decomposed components of
+    this vector to determine the direction and strength of force that apply to
+    the node. The forces are added up for each node, and weighted so that the
+    closest nodes are given the strongest force. The sum of all forces are
+    stored in \e xvel (X-velocity) and \e yvel (Y-velocity).
+
+    \snippet examples/graphicsview/elasticnodes/node.cpp 4
+
+    The edges between the nodes represent the forces that pull the nodes
+    together. By visiting each edge that is connected to this node, we can use
+    a similar approach as above to find the direction and strength of all
+    forces. These forces are subtracted from \e xvel and \e yvel.
+
+    \snippet examples/graphicsview/elasticnodes/node.cpp 5
+
+    In theory, the sum of pushing and pulling forces should stabilize to
+    precisely 0. In practise, however, they never do. To circumvent errors in
+    numerical precision, we simply force the sum of forces to be 0 when they
+    are less than 0.1.
+
+    \snippet examples/graphicsview/elasticnodes/node.cpp 6
+
+    The final step of \e calculateForces() determines the node's new position.
+    We add the force to the node's current position. We also make sure the new
+    position stays inside of our defined boundaries. We don't actually move the
+    item in this function; that's done in a separate step, from \e advance().
+
+    \snippet examples/graphicsview/elasticnodes/node.cpp 7
+
+    The \e advance() function updates the item's current position. It is called
+    from \e GraphWidget::timerEvent(). If the node's position changed, the
+    function returns true; otherwise false is returned.
+
+    \snippet examples/graphicsview/elasticnodes/node.cpp 8
+
+    The \e Node's bounding rectangle is a 20x20 sized rectangle centered around
+    its origin (0, 0), adjusted by 2 units in all directions to compensate for
+    the node's outline stroke, and by 3 units down and to the right to make
+    room for a simple drop shadow.
+
+    \snippet examples/graphicsview/elasticnodes/node.cpp 9
+
+    The shape is a simple ellipse. This ensures that you must click inside the
+    node's elliptic shape in order to drag it around. You can test this effect
+    by running the example, and zooming far enough in so that the nodes become
+    very large. Without reimplementing \l{QGraphicsItem::shape()}{shape()}, the
+    item's hit area would be identical to its bounding rectangle (i.e.,
+    rectangular).
+
+    \snippet examples/graphicsview/elasticnodes/node.cpp 10
+
+    This function implements the node's painting. We start by drawing a simple
+    dark gray elliptic drop shadow at (-7, -7), that is, (3, 3) units down and
+    to the right.
+
+    We then draw an ellipse with a radial gradient fill. This fill is either
+    Qt::yellow to Qt::darkYellow when raised, or the opposite when sunken. In
+    sunken state we also shift the center and focal point by (3, 3) to
+    emphasize the impression that something has been pushed down.
+
+    Drawing filled ellipses with gradients can be quite slow, especially when
+    using complex gradients such as QRadialGradient. This is why this example
+    uses \l{QGraphicsItem::DeviceCoordinateCache}{DeviceCoordinateCache}, a
+    simple yet effective measure that prevents unnecessary redrawing.
+
+    \snippet examples/graphicsview/elasticnodes/node.cpp 11
+
+    We reimplement \l{QGraphicsItem::itemChange()}{itemChange()} to adjust the
+    position of all connected edges, and to notify the scene that an item has
+    moved (i.e., "something has happened"). This will trigger new force
+    calculations.
+
+    This notification is the only reason why the nodes need to keep a pointer
+    back to the \e GraphWidget. Another approach could be to provide such
+    notification using a signal; in such case, \e Node would need to inherit
+    from QGraphicsObject.
+
+    \snippet examples/graphicsview/elasticnodes/node.cpp 12
+
+    Because we have set the \l{QGraphicsItem::ItemIsMovable}{ItemIsMovable}
+    flag, we don't need to implement the logic that moves the node according to
+    mouse input; this is already provided for us. We still need to reimplement
+    the mouse press and release handlers though, to update the nodes' visual
+    appearance (i.e., sunken or raised).
+
+    \section1 Edge Class Definition
+
+    The \e Edge class represents the arrow-lines between the nodes in this
+    example. The class is very simple: it maintains a source- and destination
+    node pointer, and provides an \e adjust() function that makes sure the line
+    starts at the position of the source, and ends at the position of the
+    destination. The edges are the only items that change continuously as
+    forces pull and push on the nodes.
+
+    Let's take a look at the class declaration:
+
+    \snippet examples/graphicsview/elasticnodes/edge.h 0
+
+    \e Edge inherits from QGraphicsItem, as it's a simple class that has no use
+    for signals, slots, and properties (compare to QGraphicsObject).
+
+    The constructor takes two node pointers as input. Both pointers are
+    mandatory in this example. We also provide get-functions for each node.
+
+    The \e adjust() function repositions the edge, and the item also implements
+    \l{QGraphicsItem::boundingRect()}{boundingRect()} and
+    \{QGraphicsItem::paint()}{paint()}.
+
+    We will now review its implementation.
+
+    \snippet examples/graphicsview/elasticnodes/edge.cpp 0
+
+    The \e Edge constructor initializes its arrowSize data member to 10 units;
+    this determines the size of the arrow which is drawn in
+    \l{QGraphicsItem::paint()}{paint()}.
+
+    In the constructor body, we call
+    \l{QGraphicsItem::setAcceptedMouseButtons()}{setAcceptedMouseButtons(0)}.
+    This ensures that the edge items are not considered for mouse input at all
+    (i.e., you cannot click the edges). Then, the source and destination
+    pointers are updated, this edge is registered with each node, and we call
+    \e adjust() to update this edge's start end end position.
+
+    \snippet examples/graphicsview/elasticnodes/edge.cpp 1
+
+    The source and destination get-functions simply return the respective
+    pointers.
+
+    \snippet examples/graphicsview/elasticnodes/edge.cpp 2
+
+    In \e adjust(), we define two points: \e sourcePoint, and \e destPoint,
+    pointing at the source and destination nodes' origins respectively. Each
+    point is calculated using \l{The Graphics View Coordinate System}{local
+    coordinates}.
+
+    We want the tip of the edge's arrows to point to the exact outline of the
+    nodes, as opposed to the center of the nodes. To find this point, we first
+    decompose the vector pointing from the center of the source to the center
+    of the destination node into X and Y, and then normalize the components by
+    dividing by the length of the vector. This gives us an X and Y unit delta
+    that, when multiplied by the radius of the node (which is 10), gives us the
+    offset that must be added to one point of the edge, and subtracted from the
+    other.
+
+    If the length of the vector is less than 20 (i.e., if two nodes overlap),
+    then we fix the source and destination pointer at the center of the source
+    node. In practise this case is very hard to reproduce manually, as the
+    forces between the two nodes is then at its maximum.
+
+    It's important to notice that we call
+    \l{QGraphicsItem::prepareGeometryChange()}{prepareGeometryChange()} in this
+    function. The reason is that the variables \e sourcePoint and \e destPoint
+    are used directly when painting, and they are returned from the
+    \l{QGraphicsItem::boundingRect()}{boundingRect()} reimplementation. We must
+    always call
+    \l{QGraphicsItem::prepareGeometryChange()}{prepareGeometryChange()} before
+    changing what \l{QGraphicsItem::boundingRect()}{boundingRect()} returns,
+    and before these variables can be used by
+    \l{QGraphicsItem::paint()}{paint()}, to keep Graphics View's internal
+    bookkeeping clean. It's safest to call this function once, immediately
+    before any such variable is modified.
+
+    \snippet examples/graphicsview/elasticnodes/edge.cpp 3
+
+    The edge's bounding rectangle is defined as the smallest rectangle that
+    includes both the start and the end point of the edge. Because we draw an
+    arrow on each edge, we also need to compensate by adjusting with half the
+    arrow size and half the pen width in all directions. The pen is used to
+    draw the outline of the arrow, and we can assume that half of the outline
+    can be drawn outside of the arrow's area, and half will be drawn inside.
+
+    \snippet examples/graphicsview/elasticnodes/edge.cpp 4
+
+    We start the reimplementation of \l{QGraphicsItem::paint()}{paint()} by
+    checking a few preconditions. Firstly, if either the source or destination
+    node is not set, then we return immediately; there is nothing to draw.
+
+    At the same time, we check if the length of the edge is approximately 0,
+    and if it is, then we also return.
+
+    \snippet examples/graphicsview/elasticnodes/edge.cpp 5
+
+    We draw the line using a pen that has round joins and caps. If you run the
+    example, zoom in and study the edge in detail, you will see that there are
+    no sharp/square edges.
+
+    \snippet examples/graphicsview/elasticnodes/edge.cpp 6
+
+    We proceed to drawing one arrow at each end of the edge. Each arrow is
+    drawn as a polygon with a black fill. The coordinates for the arrow are
+    determined using simple trigonometry.
+
+    \section1 GraphWidget Class Definition
+
+    \e GraphWidget is a subclass of QGraphicsView, which provides the main
+    window with scrollbars.
+
+    \snippet examples/graphicsview/elasticnodes/graphwidget.h 0
+
+    It provides a basic constructor that initializes the scene, an \e
+    itemMoved() function to notify changes in the scene's node graph, a few
+    event handlers, a reimplementation of
+    \l{QGraphicsView::drawBackground()}{drawBackground()}, and a helper
+    function for scaling the view by mouse or keyboard.
+
+    \snippet examples/graphicsview/elasticnodes/graphwidget.cpp 0
+
+    \e GraphicsWidget's constructor creates the scene, and because most items
+    move around most of the time, it sets QGraphicsScene::NoIndex. Then the
+    scene gets a fixed \l{QGraphicsScene::sceneRect}{scene rectangle}.
+    The scene is then assigned to the \e GraphWidget view.
+
+    The view enables QGraphicsView::CacheBackground to cache rendering of its
+    static and somewhat complex background. Because the graph renders a close
+    collection of small items that all move around, it's unnecessary for
+    Graphics View to waste time finding accurate update regions, so we set the
+    QGraphicsView::BoundingRectViewportUpdate viewport update mode. The default
+    would work fine, but this mode is noticably faster for this example.
+
+    To improve rendering quality, we set QPainter::Antialiasing.
+
+    The transformation anchor decides how the view should scroll when you
+    transform the view, or in our case, when we zoom in or out. We have chosen
+    QGraphicsView::AnchorUnderMouse, which centers the view on the point under
+    the mouse cursor. This makes it easy to zoom towards a point in the scene
+    by moving the mouse over it, and then rolling the mouse wheel.
+
+    Finally we give the window a minimum size that matches the scene's default
+    size, and set a suitable window title.
+
+    \snippet examples/graphicsview/elasticnodes/graphwidget.cpp 1
+
+    The last part of the constructor creates the grid of nodes and edges, and
+    gives each node an initial position.
+
+    \snippet examples/graphicsview/elasticnodes/graphwidget.cpp 2
+
+    \e GraphWidget is notified of node movement through this \e itemMoved()
+    function. Its job is simply to restart the main timer in case it's not
+    running already. The timer is designed to stop when the graph stabilizes,
+    and start once it's unstable again.
+
+    \snippet examples/graphicsview/elasticnodes/graphwidget.cpp 3
+
+    This is \e GraphWidget's key event handler. The arrow keys move the center
+    node around, the '+' and '-' keys zoom in and out by calling \e
+    scaleView(), and the enter and space keys randomize the positions of the
+    nodes. All other key events (e.g., page up and page down) are handled by
+    QGraphicsView's default implementation.
+
+    \snippet examples/graphicsview/elasticnodes/graphwidget.cpp 4
+
+    The timer event handler's job is to run the whole force calculation
+    machinery as a smooth animation. Each time the timer is triggered, the
+    handler will find all nodes in the scene, and call \e
+    Node::calculateForces() on each node, one at a time. Then, in a final step
+    it will call \e Node::advance() to move all nodes to their new positions.
+    By checking the return value of \e advance(), we can decide if the grid
+    stabilized (i.e., no nodes moved). If so, we can stop the timer.
+
+    \snippet examples/graphicsview/elasticnodes/graphwidget.cpp 5
+
+    In the wheel event handler, we convert the mouse wheel delta to a scale
+    factor, and pass this factor to \e scaleView(). This approach takes into
+    account the speed that the wheel is rolled. The faster you roll the mouse
+    wheel, the faster the view will zoom.
+
+    \snippet examples/graphicsview/elasticnodes/graphwidget.cpp 6
+
+    The view's background is rendered in a reimplementation of
+    QGraphicsView::drawBackground(). We draw a large rectangle filled with a
+    linear gradient, with a drop shadow, and then render text in top. The text
+    is rendered twice to give a similar simple drop-shadow effect.
+
+    This background rendering is quite expensive; this is why the view enables
+    QGraphicsView::CacheBackground.
+
+    \snippet examples/graphicsview/elasticnodes/graphwidget.cpp 7
+
+    The \e scaleView() helper function checks that the scale factor stays
+    within certain limits (i.e., you cannot zoom too far in nor too far out),
+    and then applies this scale.
+
+    \section1 The main() Function
+
+    In contrast to the complexity of the rest of this example, the \e main()
+    function is very simple: We create a QApplication instance, seed the
+    randomizer using qsrand(), and then create and show an instance of \e
+    GraphWidget. Because all nodes in the grid are moved initially, the \e
+    GraphWidget timer will start immediately after control has returned to the
+    event loop.
