  • Emitted either when the the number of either axes or keys changes.

    On X11 this will normally happen when the physical device routing events through the logical device changes (for example, user switches from the USB mouse to a tablet); in that case the logical device will change to reflect the axes and keys on the new physical device.

  • 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.
