Class

Gtk.Range

Description [src]

class Gtk.Range : Gtk.Widget {
  parent_instance: GtkWidget
}

GtkRange is the common base class for widgets which visualize an adjustment.

Widgets that are derived from GtkRange include GtkScale and GtkScrollbar.

Apart from signals for monitoring the parameters of the adjustment, GtkRange provides properties and methods for setting a “fill level” on range widgets. See gtk_range_set_fill_level().
