+    \brief Handler for taps and clicks.
+
+    TapHandler is a handler for taps on a touchscreen or clicks on a mouse.
+
+    Detection of a valid tap gesture depends on \l gesturePolicy.
+    Note that buttons (such as QPushButton) are often implemented not to care
+    whether the press and release occur close together: if you press the button
+    and then change your mind, you need to drag all the way off the edge of the
+    button in order to cancel the click.  Therefore the default
+    \l gesturePolicy is \c TapHandler.ReleaseWithinBounds.  If you want to require
+    that the press and release are close together in both space and time,
+    set it to \c TapHandler.DragThreshold.
+
+    For multi-tap gestures (double-tap, triple-tap etc.), the distance moved
+    must not exceed QPlatformTheme::MouseDoubleClickDistance with mouse and
+    QPlatformTheme::TouchDoubleTapDistance with touch, and the time between
+    taps must not exceed QStyleHints::mouseDoubleClickInterval().

+    \qmlproperty enumeration TapHandler::gesturePolicy
+
+    The spatial constraint for a tap or long press gesture to be recognized,
+    in addition to the constraint that the release must occur before
+    \l longPressThreshold has elapsed. If these constraints are not satisfied,
+    the \l tapped signal is not emitted, and \l tapCount is not incremented.
+    If the spatial constraint is violated, \l isPressed transitions immediately
+    from true to false, regardless of the time held.
+
+    \value TapHandler.DragThreshold
+           The event point must not move significantly. If the mouse, finger
+           or stylus moves past the system-wide drag threshold
+           (QStyleHints::startDragDistance), the tap gesture is canceled, even
+           if the button or finger is still pressed. This policy can be useful
+           whenever TapHandler needs to cooperate with other pointer handlers
+           (for example \l DragHandler), because in this case TapHandler will
+           never grab.
+
+    \value TapHandler.WithinBounds
+           If the event point leaves the bounds of the \l target item, the tap
+           gesture is canceled. The TapHandler will grab on press, but release
+           the grab as soon as the boundary constraint is no longer satisfied.
+
+    \value TapHandler.ReleaseWithinBounds
+           (the default value) At the time of release (the mouse button is
+           released or the finger is lifted), if the event point is outside
+           the bounds of the \l target item, a tap gesture is not recognized.
+           This is the default value, because it corresponds to typical button
+           behavior: you can cancel a click by dragging outside the button,
+           and you can also change your mind by dragging back inside the button
+           before release. Note that it's necessary for TapHandler to grab on
+           press and retain it until release (greedy grab) in order to detect
+           this gesture.

-    The purpose of QQuickImplicitSizeItem is not immediately clear, as both
-    the implicit size properties and signals exist on QQuickItem. However,
-    for some items - where the implicit size has an underlying meaning (such as
-    Image, where the implicit size represents the real size of the image)
-    having implicit size writable is an undesirable thing.
-
-    QQuickImplicitSizeItem redefines the properties as being readonly.
-    Unfortunately, this also means they need to redefine the change signals.
-    See QTBUG-30258 for more information.
+    QQuickImplicitSizeItem redefines the implicitWidth and implicitHeight
+    properties as readonly, as some items (e.g. Image, where the implicit size
+    represents the real size of the image) should not be able to have their
