+    \brief The Animation element is the base of all QML animations.
+
+    The Animation element cannot be used directly in a QML file.  It exists
+    to provide a set of common properties and methods, available across all the
+    other animation types that inherit from it.  Attempting to use the Animation
+    element directly will result in an error.

+    \qmlproperty bool Animation::running
+    This property holds whether the animation is currently running.
+
+    The \c running property can be set to declaratively control whether or not
+    an animation is running.  The following example will animate a rectangle
+    whenever the \l MouseArea is pressed.
+
+    \code
+    Rectangle {
+        width: 100; height: 100
+        NumberAnimation on x {
+            running: myMouse.pressed
+            from: 0; to: 100
+        }
+        MouseArea { id: myMouse }
+    }
+    \endcode
+
+    Likewise, the \c running property can be read to determine if the animation
+    is running.  In the following example the text element will indicate whether
+    or not the animation is running.
+
+    \code
+    NumberAnimation { id: myAnimation }
+    Text { text: myAnimation.running ? "Animation is running" : "Animation is not running" }
+    \endcode
+
+    Animations can also be started and stopped imperatively from JavaScript
+    using the \c start() and \c stop() methods.
+
+    By default, animations are not running. Though, when the animations are assigned to properties,
+    as property value sources using the \e on syntax, they are set to running by default.

+
+    For convenience, when a ColorAnimation is used in a \l Transition, it will

+    \ingroup qml-animation-transition
+    \since 4.7
+    \inherits Animation
+    \brief The PropertyAction element allows immediate property changes during animation.
+
+    PropertyAction is used to specify an immediate property change during an
+    animation. The property change is not animated.
+
+    It is useful for setting non-animated property values during an animation.
+
+    For example, here is a SequentialAnimation that sets the image's
+    \l {Image::}{smooth} property to \c true, animates the width of the image,
+    then sets \l {Image::}{smooth} back to \c false:
+
+    \snippet doc/src/snippets/declarative/propertyaction.qml standalone
+
+    PropertyAction is also useful for setting the exact point at which a property
+    change should occur during a \l Transition. For example, if PropertyChanges
+    was used in a \l State to rotate an item around a particular
+    \l {Item::}{transformOrigin}, it might be implemented like this:
+
+    \snippet doc/src/snippets/declarative/propertyaction.qml transition
+
+    However, with this code, the \c transformOrigin is not set until \e after
+    the animation, as a \l State is taken to define the values at the \e end of
+    a transition. The animation would rotate at the default \c transformOrigin,
+    then jump to \c Item.BottomRight. To fix this, insert a PropertyAction
+    before the RotationAnimation begins:
+
+    \snippet doc/src/snippets/declarative/propertyaction-sequential.qml sequential
+
+    This immediately sets the \c transformOrigin property to the value defined
+    in the end state of the \l Transition (i.e. the value defined in the
+    PropertyAction object) so that the rotation animation begins with the
+    correct transform origin.

+    \brief The RotationAnimation element animates changes in rotation values.
+
+    RotationAnimation is a specialized PropertyAnimation that gives control
+    over the direction of rotation during an animation.
+
+    By default, it rotates in the direction
+    of the numerical change; a rotation from 0 to 240 will rotate 240 degrees
+    clockwise, while a rotation from 240 to 0 will rotate 240 degrees
+    counterclockwise. The \l direction property can be set to specify the
+    direction in which the rotation should occur.
+
+    In the following example we use RotationAnimation to animate the rotation
+    between states via the shortest path:
+
+    \snippet doc/src/snippets/declarative/rotationanimation.qml 0
+
+    Notice the RotationAnimation did not need to set a \l target
+    value. As a convenience, when used in a transition, RotationAnimation will rotate all
+    properties named "rotation" or "angle". You can override this by providing
+    your own properties via \l {PropertyAnimation::properties}{properties} or
+    \l {PropertyAnimation::property}{property}.
+
+    Also, note the \l Rectangle will be rotated around its default
+    \l {Item::}{transformOrigin} (which is \c Item.Center). To use a different
+    transform origin, set the origin in the PropertyChanges object and apply
+    the change at the start of the animation using PropertyAction. See the
+    PropertyAction documentation for more details.
+
+    Like any other animation element, a RotationAnimation can be applied in a
+    number of ways, including transitions, behaviors and property value
+    sources. The \l {QML Animation and Transitions} documentation shows a
+    variety of methods for creating animations.

+    \brief The PropertyAnimation element animates changes in property values.
+
+    PropertyAnimation provides a way to animate changes to a property's value.
+
+    It can be used to define animations in a number of ways:
+
+    \list
+    \o In a \l Transition
+
+    For example, to animate any objects that have changed their \c x or \c y properties
+    as a result of a state change, using an \c InOutQuad easing curve:
+
+    \snippet doc/src/snippets/declarative/propertyanimation.qml transition
+
+
+    \o In a \l Behavior
+
+    For example, to animate all changes to a rectangle's \c x property:
+
+    \snippet doc/src/snippets/declarative/propertyanimation.qml behavior
+
+
+    \o As a property value source
+
+    For example, to repeatedly animate the rectangle's \c x property:
+
+    \snippet doc/src/snippets/declarative/propertyanimation.qml propertyvaluesource
+
+
+    \o In a signal handler
+
+    For example, to fade out \c theObject when clicked:
+    \qml
+    MouseArea {
+        anchors.fill: theObject
+        onClicked: PropertyAnimation { target: theObject; property: "opacity"; to: 0 }
+    }
+    \endqml
+
+    \o Standalone
+
+    For example, to animate \c rect's \c width property over 500ms, from its current width to 30:
+
+    \snippet doc/src/snippets/declarative/propertyanimation.qml standalone
+
+    \endlist
+
+    Depending on how the animation is used, the set of properties normally used will be
+    different. For more information see the individual property documentation, as well
+    as the \l{QML Animation and Transitions} introduction.
+
+    Note that PropertyAnimation inherits the abstract \l Animation element.

+    \qmlproperty string PropertyAnimation::property
+    \qmlproperty Object PropertyAnimation::target
+
+    These properties are used as a set to determine which properties should be animated.
+    The singular and plural forms are functionally identical, e.g.
+    \qml
+    NumberAnimation { target: theItem; property: "x"; to: 500 }
+    \endqml
+    has the same meaning as
+    \qml
+    NumberAnimation { targets: theItem; properties: "x"; to: 500 }
+    \endqml
+    The singular forms are slightly optimized, so if you do have only a single target/property
+    to animate you should try to use them.
+
+    The \c targets property allows multiple targets to be set. For example, this animates the
+    \c x property of both \c itemA and \c itemB:

+    NumberAnimation { targets: [itemA, itemB]; properties: "x"; to: 500 }

+    \o When used in a transition, a property animation is assumed to match \e all targets

+  \ingroup qml-animation-transition
+    \since 4.7
+    \inherits Animation
+    \brief The ParentAnimation element animates changes in parent values.
+
+    ParentAnimation is used to animate a parent change for an \l Item.
+
+    For example, the following ParentChange changes \c blueRect to become
+    a child of \c redRect when it is clicked. The inclusion of the
+    ParentAnimation, which defines a NumberAnimation to be applied during
+    the transition, ensures the item animates smoothly as it moves to
+    its new parent:
+
+    \snippet doc/src/snippets/declarative/parentanimation.qml 0
+
+    A ParentAnimation can contain any number of animations. These animations will
+    be run in parallel; to run them sequentially, define them within a
+    SequentialAnimation.
+
+    In some cases, such as when reparenting between items with clipping enabled, it is useful
+    to animate the parent change via another item that does not have clipping
+    enabled. Such an item can be set using the \l via property.
+
+    For convenience, when a ParentAnimation is used in a \l Transition, it will
+    animate any ParentChange that has occurred during the state change.
+    This can be overridden by setting a specific target item using the
+    \l target property.
+
+    Like any other animation element, a ParentAnimation can be applied in a
+    number of ways, including transitions, behaviors and property value
+    sources. The \l {QML Animation and Transitions} documentation shows a
+    variety of methods for creating animations.
