+    \class QGraphicsSceneBspTreeIndex
+    \brief The QGraphicsSceneBspTreeIndex class provides an implementation of
+    a BSP indexing algorithm for discovering items in QGraphicsScene.
+    \since 4.6
+    \ingroup multimedia
+    \ingroup graphicsview-api
+    \mainclass
+    \internal
+
+    QGraphicsSceneBspTreeIndex index use a BSP(Binary Space Partitioning)
+    implementation to discover items quickly. This implementation is
+    very efficient for static scene. It has a depth that you can set.
+    The depth directly affects performance and memory usage; the latter
+    growing exponentially with the depth of the tree. With an optimal tree
+    depth, the index can instantly determine the locality of items, even
+    for scenes with thousands or millions of items. This also greatly improves
+    rendering performance.
+
+    By default, the value is 0, in which case Qt will guess a reasonable
+    default depth based on the size, location and number of items in the
+    scene. If these parameters change frequently, however, you may experience
+    slowdowns as the index retunes the depth internally. You can avoid
+    potential slowdowns by fixating the tree depth through setting this
+    property.
+
+    The depth of the tree and the size of the scene rectangle decide the
+    granularity of the scene's partitioning. The size of each scene segment is
+    determined by the following algorithm:
+
+    The BSP tree has an optimal size when each segment contains between 0 and
+    10 items.

+
+    This value determines the depth of BSP tree. The depth
+    directly affects performance and memory usage; the latter
+    growing exponentially with the depth of the tree. With an optimal tree
+    depth, the index can instantly determine the locality of items, even
+    for scenes with thousands or millions of items. This also greatly improves
+    rendering performance.
+
+    By default, the value is 0, in which case Qt will guess a reasonable
+    default depth based on the size, location and number of items in the
+    scene. If these parameters change frequently, however, you may experience
+    slowdowns as the index retunes the depth internally. You can avoid
+    potential slowdowns by fixating the tree depth through setting this
+    property.
+
+    The depth of the tree and the size of the scene rectangle decide the
+    granularity of the scene's partitioning. The size of each scene segment is
+    determined by the following algorithm:
+
+    The BSP tree has an optimal size when each segment contains between 0 and
+    10 items.

+    Usually gesture recognizer implements a state machine, storing its state
+    internally in the recognizer object. The recognizer receives input events
+    through the \l{QGesture::}{filterEvent()} virtual function and decides
+    whether the event should change the state of the recognizer by emitting an
+    appropriate signal.
 
-/*! \internal
+    Input events should be either fed to the recognizer one by one with a
+    filterEvent() function, or the gesture recognizer should be attached to an
+    object it filters events for by specifying it as a parent object. The
+    QGesture object installs itself as an event filter to the parent object
+    automatically, the unsetObject() function should be used to remove an event
+    filter from the parent object. To make a
+    gesture that operates on a QGraphicsItem, both the appropriate QGraphicsView
+    should be passed as a parent object and setGraphicsItem() functions should
+    be used to attach a gesture to a graphics item.
+
+    This is a base class, to create a custom gesture type, you should subclass
+    it and implement its pure virtual functions.

-    \class QGestureRecognizer

-
-    \brief The QGestureRecognizer class is the base class for
-    implementing custom gestures.
-
-    This is a base class, to create a custom gesture type, you should
-    subclass it and implement its pure virtual functions.
-
-    Usually gesture recognizer implements state machine, storing its
-    state internally in the recognizer object. The recognizer receives
-    input events through the \l{QGestureRecognizer::}{filterEvent()}
-    virtual function and decides whether the parsed event should
-    change the state of the recognizer - i.e. if the event starts or
-    ends a gesture or if it isn't related to gesture at all.
-*/
-
-/*!
-    \enum QGestureRecognizer::Result
-    \since 4.6
-
-    This enum type defines the state of the gesture recognizer.
-
-    \value Ignore Gesture recognizer ignores the event.
-
-    \value NotGesture Not a gesture.
-
-    \value GestureStarted The continuous gesture has started. When the
-    recognizer is in this state, a \l{QGestureEvent}{gesture event}
-    containing QGesture objects returned by the
-    \l{QGestureRecognizer::}{getGesture()} will be sent to a widget.
-
-    \value GestureFinished The gesture has ended. A
-    \l{QGestureEvent}{gesture event} will be sent to a widget.
-
-    \value MaybeGesture Gesture recognizer hasn't decided yet if a
-    gesture has started, but it might start soon after the following
-    events are received by the recognizer. This means that gesture
-    manager shouldn't reset() the internal state of the gesture
-    recognizer.
-*/
-
-/*! \fn QGestureRecognizer::Result QGestureRecognizer::filterEvent(const QEvent *event)
-
-    This is a pure virtual function that needs to be implemented in

-    the event sequence is a gesture or not.

-
-    Returns a gesture object that will be send to the widget. This
-    function is called when the gesture recognizer changed its state
-    to QGestureRecognizer::GestureStarted or
-    QGestureRecognizer::GestureFinished.
-
-    The returned QGesture object must point to the same object in a
-    single gesture sequence.
-
-    The gesture object is owned by the recognizer itself.
-*/
-
-/*! \fn void QGestureRecognizer::reset()
-
-    Resets the internal state of the gesture recognizer.
-*/
