- * @defgroup Scroller Scroller
- * @ingroup Elementary
- *
- * A scroller holds a single object and "scrolls it around". This means that
- * it allows the user to use a scrollbar (or a finger) to drag the viewable
- * region around, allowing to move through a much larger object that is
- * contained in the scroller. The scroiller will always have a small minimum
- * size by default as it won't be limited by the contents of the scroller.
- *
- * Signals that you can add callbacks for are:
- *
- * edge,left - the left edge of the content has been reached
- *
- * edge,right - the right edge of the content has been reached
- *
- * edge,top - the top edge of the content has been reached
- *
- * edge,bottom - the bottom edge of the content has been reached
- *
- * scroll - the content has been scrolled (moved)
- *
- * scroll,anim,start - scrolling animation has started
- *
- * scroll,anim,stop - scrolling animation has stopped
- *
- * scroll,drag,start - dragging the contents around has started
- *
- * scroll,drag,stop - dragging the contents around has stopped
