\brief Handler for mouse and tablet hover.
- HoverHandler detects a hovering cursor. Since touchscreens don't generally
- offer hover events, in practice it detects a hovering mouse or tablet stylus.
+ HoverHandler detects a hovering mouse or tablet stylus cursor.
- \sa MouseArea
+ A binding to the \l hovered property is the easiest way to react when the
+ cursor enters or leaves the \l {PointerHandler::parent}{parent} Item.
+ The \l {SinglePointHandler::point}{point} property provides more detail,
+ including the cursor position. The
+ \l {PointerDeviceHandler::acceptedDevices}{acceptedDevices},
+ \l {PointerDeviceHandler::acceptedPointerTypes}{acceptedPointerTypes},
+ and \l {PointerDeviceHandler::acceptedModifiers}{acceptedModifiers}
+ properties can be used to narrow the behavior to detect hovering of
+ specific kinds of devices or while holding a modifier key.
