public sealed class GutterLines : Object

Collected information about visible lines.

The `GtkSourceGutterLines` object is used to collect information about visible lines.

Use this from your [signal@GutterRenderer:GtkSourceGutterLines:query-data] to collect the necessary information on visible lines. Doing so reduces the number of passes through the text btree allowing GtkSourceView to reach more frames-per-second while performing kinetic scrolling.
