+ A **hover event** is when a pointer moves within the bounds of a custom actor (e.g. mouse pointer or hover pointer).
+ A **wheel event** is when the mouse wheel (or similar) is moved while hovering over an actor (via a mouse pointer or hover pointer).
-If the control needs to utilise hover and wheel events, then the correct behaviour flag should be used when constructing the control and then the appropriate method should be overridden.
