/**
* @brief Actor is the primary object with which Dali applications interact.
*
*
* <h3>Multi-Touch Events:</h3>
*
- * Touch events are received via signals; see Actor::TouchedSignal() for more details.
+ * Touch or hover events are received via signals; see Actor::TouchedSignal() and Actor::HoveredSignal() for more details.
*
* <i>Hit Testing Rules Summary:</i>
*
- * - An actor is only hittable if the actor's touch signal has a connection.
+ * - An actor is only hittable if the actor's touch or hover signal has a connection.
* - An actor is only hittable when it is between the camera's near and far planes.
* - If an actor is made insensitive, then the actor and its children are not hittable; see IsSensitive()
* - If an actor's visibility flag is unset, then none of its children are hittable either; see IsVisible()
* // Depth-first traversal within current layer, visiting parent first
*
* // Check whether current actor should be hit-tested
- * IF ( TOUCH-SIGNAL-NOT-EMPTY &&
+ * IF ( ( TOUCH-SIGNAL-NOT-EMPTY || HOVER-SIGNAL-NOT-EMPTY ) &&
* ACTOR-HAS-NON-ZERO-SIZE &&
* ACTOR-WORLD-COLOR-IS-NOT-TRANSPARENT )
* {
* also be considered a Stencil Actor.
* Non-renderable actors can be hit regardless of whether a stencil actor is hit or not.
*
- * <i>Touch Event Delivery:</i>
+ * <i>Touch or hover Event Delivery:</i>
*
* - Delivery
- * - The hit actor's touch signal is emitted first; if it is not consumed by any of the listeners,
- * the parent's touch signal is emitted, and so on.
+ * - The hit actor's touch or hover signal is emitted first; if it is not consumed by any of the listeners,
+ * the parent's touch or hover signal is emitted, and so on.
* - The following pseudocode shows the delivery mechanism:
* @code
* EMIT-TOUCH-SIGNAL( ACTOR )
* }
* }
* }
+ *
+ * EMIT-HOVER-SIGNAL( ACTOR )
+ * {
+ * IF ( HOVER-SIGNAL-NOT-EMPTY )
+ * {
+ * // Only do the emission if hover signal of actor has connections.
+ * CONSUMED = HOVERED-SIGNAL( HOVER-EVENT )
+ * }
+ *
+ * IF ( NOT-CONSUMED )
+ * {
+ * // If event is not consumed then deliver it to the parent unless we reach the root actor
+ * IF ( ACTOR-PARENT )
+ * {
+ * EMIT-HOVER-SIGNAL( ACTOR-PARENT )
+ * }
+ * }
+ * }
* @endcode
* - If there are several touch points, then the delivery is only to the first touch point's hit
- * actor (and its parents). There will be NO touch signal delivery for the hit actors of the
+ * actor (and its parents). There will be NO touch or hover signal delivery for the hit actors of the
* other touch points.
* - The local coordinates are from the top-left (0.0f, 0.0f, 0.5f) of the hit actor.
*
* - Leave State
* - A "Leave" state is set when the first point exits the bounds of the previous first point's
* hit actor (primary hit actor).
- * - When this happens, the last primary hit actor's touch signal is emitted with a "Leave" state
+ * - When this happens, the last primary hit actor's touch or hover signal is emitted with a "Leave" state
* (only if it requires leave signals); see SetLeaveRequired().
*
* - Interrupted State
- * - If a system event occurs which interrupts the touch processing, then the last primary hit
- * actor's touch signals are emitted with an "Interrupted" state.
- * - If the last primary hit actor, or one of its parents, is no longer touchable, then its
- * touch signals are also emitted with an "Interrupted" state.
+ * - If a system event occurs which interrupts the touch or hover processing, then the last primary hit
+ * actor's touch or hover signals are emitted with an "Interrupted" state.
+ * - If the last primary hit actor, or one of its parents, is no longer touchable or hoverable, then its
+ * touch or hover signals are also emitted with an "Interrupted" state.
* - If the consumed actor on touch-down is not the same as the consumed actor on touch-up, then
* touch signals are also emitted from the touch-down actor with an "Interrupted" state.
+ * - If the consumed actor on hover-start is not the same as the consumed actor on hover-finished, then
+ * hover signals are also emitted from the hover-started actor with an "Interrupted" state.
* <h3>Key Events:</h3>
*
* Key events are received by an actor once set to grab key events, only one actor can be set as focused.
