- * that wants to know if user tapped anywhere on the screen could use this.
- * - Derived: client can use the forward-pointer-events-to-gesture-helper
- * functionality by deriving from CGestureControl. Client has to create at
- * least one visual that captures pointer events. This base class will
- * receive the events and forward them to CGestureHelper.
- *
- * The client can keep other widgets on top of this control, to allow them
- * priority of capturing the pointer events.
