Function
Pangoitemize
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).
Parameters
context-
Type:
PangoContextA structure holding information that affects the itemization process.
The data is owned by the caller of the function. text-
Type:
const char*The text to itemize. Must be valid UTF-8.
The data is owned by the caller of the function. The value is a NUL terminated UTF-8 string. start_index-
Type:
intFirst byte in
textto process. length-
Type:
intThe number of bytes (not characters) to process after
start_index. This must be >= 0. attrs-
Type:
PangoAttrListThe set of attributes that apply to
text.The data is owned by the caller of the function. cached_iter-
Type:
PangoAttrIteratorCached attribute iterator.
The argument can be NULL.The data is owned by the caller of the function.
Return value
Type: A list of PangoItem*
A GList of
PangoItem structures. The items should be freed using
pango_item_free() in combination with g_list_free_full().
| The caller of the function takes ownership of the data, and is responsible for freeing it. |
