Function
Pango.itemize
Declaration [src]
GList*
pango_itemize (
PangoContext* context,
const char* text,
int start_index,
int length,
PangoAttrList* attrs,
PangoAttrIterator* cached_iter
)
Description [src]
Breaks a piece of text into segments with consistent directional level and font.
Each byte of text
will be contained in exactly one of the items in the
returned list; the generated list of items will be in logical order (the
start offsets of the items are ascending).
cached_iter
should be an iterator over attrs
currently positioned
at a range before or containing start_index
; cached_iter
will be
advanced to the range covering the position just after
start_index
+ length
. (i.e. if itemizing in a loop, just keep passing
in the same cached_iter
).
