| class Alf::IAlfScrollBarWidget : public Alf::IAlfWidget |
Interface for the scrollbar widget.

Track (Place holder for Thumb)

The communication between scrollbar and scrollable widget happens through events. Scrollbar handles only pointer events which are converted to higher level events like EEventScrollUp, EEventScrollDown, EEventScrollLeft, EEventScrollRight, EEventScrollPageUp, EEventScrollPageDown, EEventScrollPageLeft and EEventScrollPageRight and sent to scrollable widget.Scrollable widget can also generate similar higher level events in response to key and pointer events.In which case it is scrollable widget's resposibility to send these events to scrollbar.
