setLower
Sets the minimum value of the adjustment.
When setting multiple adjustment properties via their individual setters, multiple signal@Gtk.Adjustment::changed signals will be emitted. However, since the emission of the signal@Gtk.Adjustment::changed signal is tied to the emission of the ::notify signals of the changed properties, it’s possible to compress the signal@Gtk.Adjustment::changed signals into one by calling g_object_freeze_notify() and g_object_thaw_notify() around the calls to the individual setters.
Alternatively, using a single g_object_set() for all the properties to change, or using method@Gtk.Adjustment.configure has the same effect.
