PgAttributeIterator

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.

PangoAttrIterator* pangoAttrIterator;

void getFont(PgFontDescription desc, PgLanguage language, ListSG extraAttrs);

bool next();

Constructors

this this(PangoAttrIterator* pangoAttrIterator, bool ownedRef): Sets our main struct and passes it to the parent class.

Functions

copy PgAttributeIterator copy(): Copy a PangoAttrIterator
destroy void destroy(): Destroy a PangoAttrIterator and free all associated memory.
get PgAttribute get(PangoAttrType type): Find the current attribute of a particular type at the iterator location. When multiple attributes of the same type overlap, the attribute whose range starts closest to the current location is used.
getAttrs ListSG getAttrs(): Gets a list of all attributes at the current position of the iterator.
getFont void getFont(PgFontDescription desc, PgLanguage language, ListSG extraAttrs): Get the font and other attributes at the current iterator position.
getPgAttributeIteratorStruct PangoAttrIterator* getPgAttributeIteratorStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
next bool next(): Advance the iterator until the next change of style.
range void range(int start, int end): Get the range of the current segment. Note that the stored return values are signed, not unsigned like the values in PangoAttribute To deal with this API oversight, stored return values that wouldn't fit into a signed integer are clamped to G_MAXINT.

Variables
