Scrollbar.size

Description

The current dimensions of this element.

Initially undefined, and unless explicitly set by a script, it is defined by a?LayoutManager?. A script can explicitly set size before the layout manager is invoked to establish an element size other than the?preferredSize?or the default size, but this is not recommended. Defined as [bounds.width, bounds.height]. Setting an element’s size changes its bounds property, and vice-versa.
