pangoLayoutGetLineReadonly {RGtk2} | R Documentation

## pangoLayoutGetLineReadonly

### Description

Retrieves a particular line from a `PangoLayout`.

### Usage

    pangoLayoutGetLineReadonly(object, line)

### Arguments

``object`` | [`PangoLayout`] a `PangoLayout`
``line`` | [integer] the index of a line, which must be between 0 and `pango_layout_get_line_count(layout) - 1`, inclusive.

### Details

This is a faster alternative to `pangoLayoutGetLine`, but the user is not expected to modify the contents of the line (glyphs, glyph widths, etc.). Since 1.16

### Value

[`PangoLayoutLine`] the requested `PangoLayoutLine`, or `NULL` if the index is out of range. This layout line can be ref'ed and retained, but will become invalid if changes are made to the `PangoLayout`. No changes should be made to the line.
