GI.Pango.Structs.AttrIterator

The #PangoAttrIterator structure is used to represent an iterator through a #PangoAttrList. A new iterator is created with pango_attr_list_get_iterator(). Once the iterator is created, it can be advanced through the style changes in the text using pango_attr_iterator_next(). At each style change, the range of the current style segment and the attributes currently in effect can be queried.
