~~Title: Efl.Ui.Scrollbar~~
====== Efl.Ui.Scrollbar (interface) ======

===== Description =====

%%Interface used by widgets which can display scrollbars, enabling them to hold more content than actually visible through the viewport. A scrollbar contains a draggable part (thumb) which allows the user to move the viewport around the content. The size of the thumb relates to the size of the viewport compared to the whole content.%%
