Class
GtkSourceGutterLines
Description [src]
final class GtkSource.GutterLines : GObject.Object {
/* No available fields */
}Collected information about visible lines.
The GtkSourceGutterLines object is used to collect information about
visible lines.
Use this from your GtkSourceGutterRenderer::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.

gtk_source_gutter_lines_get_last
Gets the line number (starting from 0) for the last line that is user visible.
gtk_source_gutter_lines_has_any_class
