/**
* @brief Actor is the primary object with which Dali applications interact.
*
* - 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()
+ * - 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().
* - To be hittable, an actor must have a non-zero size.
- * - If an actor's world color is fully transparent, then it is not hittable; see GetCurrentWorldColor()
+ * - If an actor's world color is fully transparent, then it is not hittable; see GetCurrentWorldColor().
*
* <i>Hit Test Algorithm:</i>
*
* {
* // Only hit-test the actor and its children if it is sensitive and visible
* IF ( ACTOR-IS-SENSITIVE &&
- * ACTOR-IS-VISIBLE )
+ * ACTOR-IS-VISIBLE &&
+ * ACTOR-IS-ON-STAGE )
* {
* // Depth-first traversal within current layer, visiting parent first
*
- * // Check whether current actor should be hit-tested
+ * // Check whether current actor should be hit-tested.
* IF ( ( TOUCH-SIGNAL-NOT-EMPTY || HOVER-SIGNAL-NOT-EMPTY ) &&
* ACTOR-HAS-NON-ZERO-SIZE &&
* ACTOR-WORLD-COLOR-IS-NOT-TRANSPARENT )
* {
* IF ( ACTOR-IS-OVERLAY || ( DISTANCE-TO-ACTOR < DISTANCE-TO-LAST-HIT-ACTOR ) )
* {
- * // The current actor is the closest actor that was underneath the touch
+ * // The current actor is the closest actor that was underneath the touch.
* LAST-HIT-ACTOR = CURRENT-ACTOR
* }
* }
* }
*
- * // Keep checking children, in case we hit something closer
+ * // Keep checking children, in case we hit something closer.
* FOR-EACH CHILD (in order)
* {
* IF ( CHILD-IS-NOT-A-LAYER )
* // Continue traversal for this child's sub-tree
* HIT-TEST-WITHIN-LAYER ( CHILD )
* }
- * // else we skip hit-testing the child's sub-tree altogether
+ * // else we skip hit-testing the child's sub-tree altogether.
* }
* }
* }
*
* Hit Priority of above Actor tree (all overlays): 1 - Lowest. 6 - Highest.
* @endcode
- * - Stencil Actors can be used to influence the result of hits on renderable actors within a layer.
- * If a Stencil Actor exists on a layer and that Actor is marked visible then a successful
- * hit on a renderable actor can only take place in the area that the stencil Actor marks as visible.
- * The hit can be in any Stencil Actor in that layer, but must be in the region of one of them.
- * Stencil Actor inheritance behaves as with rendering in that any child of a Stencil Actor will
- * also be considered a Stencil Actor.
- * Non-renderable actors can be hit regardless of whether a stencil actor is hit or not.
+ * For more information, see SetDrawMode().
*
* <i>Touch or hover Event Delivery:</i>
*
*
* IF ( NOT-CONSUMED )
* {
- * // If event is not consumed then deliver it to the parent unless we reach the root actor
+ * // 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 or hover 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.
*
* 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.
