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.

class PgAttributeIterator {

protected

PangoAttrIterator* pangoAttrIterator;

protected

bool ownedRef;

PangoAttrIterator* getPgAttributeIteratorStruct();

void* getStruct();

this(PangoAttrIterator* pangoAttrIterator, bool ownedRef);

PgAttributeIterator copy();

void destroy();

PgAttribute get(PangoAttrType type);

ListSG getAttrs();

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

bool next();

void range(int start, int end);

}

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(): 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
