-    \class QGesture
-    \since 4.6
-    \preliminary
-
-    \brief The QGesture class is the base class for implementing custom
-    gestures.
-
-    This class represents both an object that recognizes a gesture out of a set
-    of input events (a gesture recognizer), and a gesture object itself that
-    can be used to get extended information about the triggered gesture.
-
-    The class has a list of properties that can be queried by the user to get
-    some gesture-specific parameters (for example, an offset of a Pan gesture).
-
-    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.
-
-    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.
-
-    \sa QPanGesture
+    When creating custom gesture recognizers, they might add new
+    properties to the gesture object, or custom gesture developers
+    might subclass the QGesture objects to provide some extended
+    information.
