AdjustmentSignalName

Emitted when one or more of the GtkAdjustment properties have been changed.

Note that the [propertyGtk.Adjustment:value] property is covered by the [signalGtk.Adjustment::value-changed] signal.

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

Note that getting this signal doesn’t itself guarantee that the value of the property has actually changed. When it is emitted is determined by the derived GObject class. If the implementor did not create the property with G_PARAM_EXPLICIT_NOTIFY, then any call to g_object_set_property() results in notify being emitted, even if the new value is the same as the old. If they did pass G_PARAM_EXPLICIT_NOTIFY, then this signal is emitted only when they explicitly call g_object_notify() or g_object_notify_by_pspec(), and common practice is to do that only when the value has actually changed.

This signal is typically used to obtain change notification for a single property, by specifying the property name as a detail in the g_signal_connect() call, like this:

(C Language Example):

g_signal_connect (text_view->buffer, "notify::paste-target-list",
                  G_CALLBACK (gtk_text_view_target_list_notify),
                  text_view)

It is important to note that you must use canonical parameter names as detail strings for the notify signal.

Emitted when the value has been changed.

The minimum value of the adjustment.

The page increment of the adjustment.

The page size of the adjustment.

Note that the page-size is irrelevant and should be set to zero if the adjustment is used for a simple scalar value, e.g. in a GtkSpinButton.

The step increment of the adjustment.

The maximum value of the adjustment.

Note that values will be restricted by upper - page-size if the page-size property is nonzero.

The value of the adjustment.
