Layout.getLineReadonly

Retrieves a particular line from a pango.layout.Layout.

This is a faster alternative to pango.layout.Layout.getLine, but the user is not expected to modify the contents of the line (glyphs, glyph widths, etc.).

class Layout
getLineReadonly
(
int line
)

Parameters

line int

the index of a line, which must be between 0 and pango_layout_get_line_count(layout) - 1, inclusive.

Return Value

Type: pango.layout_line.LayoutLine

the requested pango.layout_line.LayoutLine, 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 pango.layout.Layout. No changes should be made to the line.
