Detailed Description

\qmltype HoverHandler \instantiates QQuickHoverHandler \inherits SinglePointHandler \inqmlmodule QtQuick

Handler for mouse and tablet hover.

HoverHandler detects a hovering mouse or tablet stylus cursor.

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.

The \l cursorShape property allows changing the cursor whenever \l hovered changes to true.
