cp.ui.ScrollArea
A ScrollArea represents an AXScrollArea. They primarily function as a "portal"
to view a larger area of the contained axuielement within (accessed via the AXContents attribute),
and also provide access to the vertical and horizontal scroll bars (accessed via the
verticalScrollBar and horizontalScrollBar properties).
The class that wraps the AXContents attribute can be provided via the contentsInit parameter in the
constructor. If not provided it defaults to Element.
The ScrollArea also delegates to the contents property, so you can access
any properties of the contained Element directly.
For example, if you have a ScrollArea with a contents of a TextField,
you can normally access the text value via the TextField.value property.
However, if you want to access the text value via the ScrollArea itself, you can do so
via the ScrollArea.value property, like so:
local scrollArea = ScrollArea(parent, ui, TextArea)
-- via `contents`:
local value = scrollArea.contents:value()
--- via delegation:
local value = scrollArea:value()It also has a Builder that supports customising an Element Builder
to create a ScrollArea with a specified contents Element type. For example, another way to
define our ScrollArea that contains a TextField is:
local scrollAreaWithTextField = ScrollArea:containing(TextField)
local scrollArea = scrollAreaWithTextField(parent, ui)The main advantage of this style is that you can pass the Builder in to other Element types
that require an "Element init" that will only be provided a parent and UI finder.
This is a subclass of Element.
