Here, the Scrollable object is created by using an existing layer, and adding scrollbars to it. Look at the beginning of the source if you want to try this. You usually don't need to call this, since the scrollbars are updated periodically without intervention. Return the container layer. Use this layer to move or resize the scrollable component.
Valid values are 'show', 'hide', or 'auto'.
The strings must be in lowercase. More generally, all the properties above can be set, with the exception of layer. The complete archive with the icon used by the scrollbars can be found here .
