class LayoutIter(pointer: <Error class: unknown class><<Error class: unknown class>>)

A PangoLayoutIter can be used to iterate over the visual extents of a PangoLayout.

To obtain a PangoLayoutIter, use method@Pango.Layout.get_iter.

The PangoLayoutIter structure is opaque, and has no user-visible fields.
