TextAreaViewport

sealed interface TextAreaViewport(source)

Immutable outer viewport requested by a multiline text editor.

The active runtime resolves nine-pixel logical line boxes, additional line spacing, and frame insets while preserving the requested width. Values own no runtime resources and may be shared across threads.
