Alf::IAlfScrollBarDefaultBaseElement Class Reference
| class Alf::IAlfScrollBarDefaultBaseElement : public Alf::IAlfInterfaceBase |
An interface for the default base element of the scrollbar.
The default base element is an interface that contains the basic layouting and scrolling logic of the scrollbar widget. The base element provides a simple scrollbar visualization. It allows the user to: 1. Specify the TotalLength ViewLength and ThumbWidth 2. Specify the opacity of thumb with respect to widget opacity
The default base element of the scrollbar uses Anchor Layout
The default base element also acts as an eventhandler and currently listens to following events: 1. EEventModelChanged, EEventScrollBarClicked
default base element handles EEventScrollBarClicked event(Custom Event) which are convetred to higher level events like EEventScrollUp ,EEventScrollDown,EEventScrollLeft,EEventScrollRight , On receiving these events, the default base element accordingly changes the position of the thumb
