Method
Pango.Item.split
Declaration [src]
PangoItem*
pango_item_split (
PangoItem* orig,
int split_index,
int split_offset
)
Description [src]
Modifies orig
to cover only the text after split_index
, and
returns a new item that covers the text before split_index
that
used to be in orig
.
You can think of split_index
as the length of the returned item.
split_index
may not be 0, and it may not be greater than or equal
to the length of orig
(that is, there must be at least one byte
assigned to each item, you can’t create a zero-length item).
split_offset
is the length of the first item in chars, and must be
provided because the text used to generate the item isn’t available,
so pango_item_split()
can’t count the char length of the split items itself.
Parameters

int |
byte index of position to split item, relative to the start of the item |
|
split_offset |
int |
number of chars between start of |
Return value
