GutterLines

open class GutterLines(pointer: <Error class: unknown class><<Error class: unknown class>>)

Collected information about visible lines.

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

Use this from your signal@GutterRenderer::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.

getView

open fun getView(): <Error class: unknown class>

Gets the class@Gtk.TextView that the GtkSourceGutterLines represents.

hasAnyClass

open fun hasAnyClass(line: <Error class: unknown class>): Boolean

Checks to see if the line has any GQuark classes set. This can be used to help renderer implementations avoid work if nothing has been set on the class.

hasClass

open fun hasClass(line: <Error class: unknown class>, name: String): Boolean

Checks to see if method@GutterLines.add_class was called with the @name for @line.

hasQclass

open fun hasQclass(line: <Error class: unknown class>, qname: <Error class: unknown class>): Boolean

Checks to see if method@GutterLines.add_qclass was called with the quark denoted by @qname for @line.

isCursor

open fun isCursor(line: <Error class: unknown class>): Boolean

Checks to see if @line contains the insertion cursor.

isPrelit

open fun isPrelit(line: <Error class: unknown class>): Boolean

Checks to see if the view had a selection and if that selection overlaps

removeClass
