public class LayoutLine

A `PangoLayoutLine` represents one of the lines resulting from laying out a paragraph via `PangoLayout`.

`PangoLayoutLine` structures are obtained by calling [method@Pango.Layout.get_line] and are only valid until the text, attributes, or settings of the parent `PangoLayout` are modified.
