pangoItemize {RGtk2} | R Documentation

## pangoItemize

### Description

Breaks a piece of text into segments with consistent directional level and shaping engine. 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).

### Usage

    pangoItemize(context, text, start.index, length, attrs, cached.iter = NULL)

### Arguments

``context`` | [`PangoContext`] a structure holding information that affects the itemization process.
``text`` | [char] the text to itemize.
``start.index`` | [integer] first byte in `text` to process
``length`` | [integer] 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`.
``cached.iter`` | [`PangoAttrIterator`] Cached attribute iterator, or `NULL`

### Details

`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`).

### Value

[list] a `list` of `PangoItem` structures.
