Variable: GtkSourceGutter

const GtkSourceGutter: "GtkSourceGutter"

Gutter object for View.

The GtkSourceGutter object represents the left or right gutter of the text view. It is used by View to draw the line numbers and Marks that might be present on a line. By packing additional GutterRenderer objects in the gutter, you can extend the gutter with your own custom drawings.

To get a GtkSourceGutter, use the View.get_gutter function.

The gutter works very much the same way as cells rendered in a Gtk.TreeView. The concept is similar, with the exception that the gutter does not have an underlying Gtk.TreeModel. The builtin line number renderer is at position %GTK_SOURCE_VIEW_GUTTER_POSITION_LINES (-30) and the marks renderer is at %GTK_SOURCE_VIEW_GUTTER_POSITION_MARKS (-20). The gutter sorts the renderers in ascending order, from left to right. So the marks are displayed on the right of the line numbers.
