Adjustment.setLower
void setLower(double lower)Sets the minimum value of the adjustment.
When setting multiple adjustment properties via their individual setters, multiple #GtkAdjustment::changed signals will be emitted. However, since the emission of the #GtkAdjustment::changed signal is tied to the emission of the #GObject::notify signals of the changed properties, it’s possible to compress the #GtkAdjustment::changed signals into one by calling gobject.object.ObjectWrap.freezeNotify and gobject.object.ObjectWrap.thawNotify around the calls to the individual setters.
Alternatively, using a single gobject.object.ObjectWrap.set for all the properties to change, or using gtk.adjustment.Adjustment.configure has the same effect of compressing #GtkAdjustment::changed emissions.
Parameters
lower | the new minimum value |
