Class

GtkAdjustment

Description [src]

class Gtk.Adjustment : GObject.InitiallyUnowned
{
  /* No available fields */
}

A model for a numeric value.

The GtkAdjustment has an associated lower and upper bound. It also contains step and page increments, and a page size.

Adjustments are used within several GTK widgets, including GtkSpinButton, GtkViewport, GtkScrollbar and GtkScale.

The GtkAdjustment object does not update the value itself. Instead it is left up to the owner of the GtkAdjustment to control the value.
