+/*! \class QTouchEvent
+    \brief The QTouchEvent class contains parameters that describe a touch event
+.
+    \since 4.6
+    \ingroup events
+
+    Touch events occur when pressing, releasing, or moving one or more
+    touch points on a touch device (such as a touch-screen or
+    track-pad), and if the widget has the Qt::WA_AcceptTouchEvents
+    attribute.
+
+    All touch events are of type QEvent::TouchBegin,
+    QEvent::TouchUpdate, or QEvent::TouchEnd. The touchPoints()
+    function returns a list of all touch points contained in the event.
+    Information about each touch point can be retreived using the
+    QTouchEvent::TouchPoint class.
+
+    Similar to QMouseEvent, Qt automatically grabs each touch point on
+    the first press inside a widget; the widget will receive all
+    updates for the touch point until it is released. Note that it is
+    possible for a widget to receive events for multiple touch points,
+    and that multiple widgets may be receiving touch events at the same
+    time.
+
+    A touch event contains a special accept flag that indicates
+    whether the receiver wants the event. By default, the event is
+    accepted. You should call ignore() if the touch event is not handled by
+    your widget. A QEvent::TouchBegin event is propagated up the parent widget
+    chain until a widget accepts it with accept(), or an event filter
+    consumes it. If the QEvent::TouchBegin event is neither accepted nor consumed,
+    then mouse events are simulated from the state of the first touch
+    point.
+
+    The Qt::TouchPointState enum describes the different states that a
+    touch point may have.

+                    point. Unlike touch-screens, Qt allows users to only interact with a single

+    \class QGesture
+    \since 4.6
+
+    \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.

+    A QCheckBox is an option button that can be switched on (checked) or off
+    (unchecked). Checkboxes are typically used to represent features in an
+    application that can be enabled or disabled without affecting others, but
+    different types of behavior can be implemented. For example, a
+    QButtonGroup can be used to group check buttons logically, allowing
+    exclusive checkboxes. However, QButtonGroup does not provide any visual
+    representation.
+
+    The image below further illustrates the differences between exclusive and
+    non-exclusive checkboxes.

     Whenever a checkbox is checked or cleared it emits the signal
-    stateChanged(). Connect to this signal if you want to trigger an
-    action each time the checkbox changes state. You can use
-    isChecked() to query whether or not a checkbox is checked.
-
-    In addition to the usual checked and unchecked states, QCheckBox
-    optionally provides a third state to indicate "no change". This
-    is useful whenever you need to give the user the option of neither
-    checking nor unchecking a checkbox. If you need this third state,
-    enable it with setTristate(), and use checkState() to query the current
-    toggle state.
-
-    Just like QPushButton, a checkbox displays text, and optionally a
-    small icon. The icon is set with setIcon(). The text can be set in
-    the constructor or with setText(). A shortcut key can be specified
-    by preceding the preferred character with an ampersand. For
-    example:
