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`	`PangoContext`
	A structure holding information that affects the itemization process.
	The data is owned by the caller of the function.
`text`	`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`	`int`
	First byte in `text` to process.
`length`	`int`
	The number of bytes (not characters) to process after `start_index`. This must be >= 0.
`attrs`	`PangoAttrList`
	The set of attributes that apply to `text`.
	The data is owned by the caller of the function.
`cached_iter`	`PangoAttrIterator`
	Cached attribute iterator.
	The argument can be `NULL`.
	The data is owned by the caller of the function.

Return value

Returns:	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.
