LayoutLine

class LayoutLine(pointer: <Error class: unknown class><<Error class: unknown class>>, cleaner: <Error class: unknown class>? = null)

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.
