public class LayoutLine

The LayoutLine structure represents one of the lines resulting from laying out a paragraph via Layout.

LayoutLine structures are obtained by calling get_line and are only valid until the text, attributes, or settings of the parent Layout are modified.

Routines for rendering PangoLayout objects are provided in code specific to each rendering system.
